urban industrial stream restoration (U.S.)


From Susan J. Tweit's Walking Nature Home Blog

"As I worked my way gradually upstream between trail and creek, I thought about how this block of urban creek and its thread of habitat for people and wilder life has changed. When I first saw this shallow spring creek, it ran ruler-straight between dirt banks thinly hazed by a prickly growth of invasive annual weeds. Chunks of concrete protruded from the dirt here and there, along with oozing spills of asphalt, rusting fence wire and pieces of cast-iron engine blocks, and other remnants of the place's industrial past, the whole festooned with windblown trash.

It was not a thing of beauty. But Richard and I had just purchased the formerly industrial property on the other side of the creek. It came complete with six-foot-high chain-link fence topped with sagging barbed wire, crumbling century-old brick shop building, rusting junk, and knee-high weeds. (Our friends thought we were crazy.) Richard wanted the place for the shop, which he had already restored in his mind's eye for an office and studio; I was drawn to that slender thread of water.

I have always wanted a creek to play with, and I was not daunted by the shabby condition of the one I got. Right away, before we pulled up the posts and removed the fence around the property (we donated both to the town public works department), before we hauled away many construction dumpsters of unidentifiable industrial detritus to clear a space for our house-to-be, before Richard cleared the old shop building down to its beautiful timber-frame and brick bones and fixed it up, before we built our house and planted wildflowers and constructed our kitchen garden in the embrace of one old u-shaped stretch of cement wall left from the property's industrial past, we set to work reclaiming the creek.

First came weeding: Richard and I spent whole hot, sweaty weekend days pulling tumbleweed, cheatgrass, and kochia by the trailer-load. We grubbed out weedy Siberian elm trees and Canada thistle. When the annual weeds sprouted from the carpet of the previous year's seeds, we burned them with a propane torch, hoed them, and sprayed them. And then we planted native shrubs to begin the slow process of reweaving the natural community: red-twig dogwood, golden-currant, skunkbrush sumac, chokecherry, Indian plum, rabbitbrush, and my favorite, big sagebrush with its silvery-green leaves and pungent fragrance.

As we weeded and watered the tiny sprigs of shrubs that were all we could afford, other natives returned. Two clumps of streambank willow sprang up just above the creek, their wand-like stems reaching five and six feet tall and casting lacy shade over the bare bank. Soon more clumps of willow appeared, sprouting from the underground roots of those pioneers. Indian ricegrass, with its cloud of seedheads, appeared on the dry upper bank, along with purple aster and scarlet globemallow.

Over the decade-plus since, we have urged the native plants along in recolonizing this block of formerly blighted creek, spreading seeds here, pulling weeds there, planting a few more shrubs, plus a rescued clump of wild Rocky Mountain irises, and a couple of cottonwood trees. We have watched the butterflies return on fluttering wings to feed from the wildflowers and lay their eggs on their favorite plants, the bees buzz in to gather pollen, and the hummingbirds hover, sipping nectar. We have heard Northern dippers practice their warbling songs in the concrete culvert where the creek goes under the street, and seen tiny trout flash in the water under the shade of the willows."

urban biodiversity (moths, starlings) toronto

Have been finding some great stuff on the Urban Biodiversity Facebook Group (Toronto) page:

From last summer:

Discover the "butterflies of the night" at the annual High Park Moth Night with the Toronto Entomologists Association. TEA leaders (Dave Beadle, Tom Mason) and members will set up special lights and help us identify moths. Meet at the benches across from the Grenadier restaurant at 8:15 pm. This outing is especially good for children - bring the whole family! Please bring flashlights, insect containers, moth guides if you have them.

And this recent video of a Starling Murmuration at Yonge and Dundas:

Roerich Garden Project (Montreal)


"Emily Rose Michaud is an interdisciplinary artist working at the intersections of community development, civic participation, performance, and land art. In recent years, her experimental and socially driven practice has resulted in a series of performances incorporating living ‘sproutfits’ and tapestries, a guerilla gardener’s ensemble, an electronic book designed to be reproduced and remixed by others (roerichproject.artefati.ca) and the Roerich Garden Project – a three-year land art project in a post-industrial railyard turned urban meadow.

She is also part of Sprout Out Loud! which is an on-growing gardener's ensemble that seeks to support and develop the relationship between residents and the land around them. This project seeks to:
- Engage with the meadow creatively and document how people use and care about this space
- Valorize this living space before it is forgotten in silence
- Draw attention to the city's plans and provoke dialogue
- Reclaim the commons, activate unused urban spaces, re-enchant the public with the natural world and living systems of the urban core

- Invite others to plant similar ideas in their own environments where needed"

Renaturalized (Broken City Lab - Windsor)


When the City of Windsor was on strike the summer of 2009, mowing parks and other city owned property was halted. Many of these areas became "naturalized" and Broken City Lab had the brilliant idea to do a bit of activism and get people to take notice of these areas in a different way:

From their Blog in July 2009: "We recently decided to demarcate some of many accidental meadows across Windsor with these Naturalized Area signs. In hopes that these signs might momentarily allow residents of Windsor to look at these naturalized spaces for what they are—that is, wonderful additions to our urban landscape—instead of the result of a politically-charged issue, we spent the earlier part of this week designing the signs, getting them printed, drilling holes, and installing them."

Green Alleys... je t'aime! (Montreal)


Reading about this made my day! I love the Promenade Plantée in Paris and want to explore the High Line in NYC and now these Green Alleys in Montreal! Great idea!

Montreal boroughs build green alleys
- Flowers, trees to help make areas more appealing (CBC Article - July 2011)

The Montreal borough of Mercier-Hochelaga-Maisonneuve is working on making its alleyways a friendlier place to be — both for local residents and the environment.

The neighbourhood, located in the east end of the city, said Wednesday that it would invest $20,000 to plant flowers and trees in four alleys this year.

Borough mayor Réal Ménard said the initiative is designed to make the areas more inviting to the public, creating spaces for people to sit and relax.

"It's a gathering event for [people]," he said.

The increase in foot traffic will also discourage criminals and drug users because they will be unwilling to break laws in the presence of other citizens, Ménard said.

With the addition of four new green alleyways, the borough will have a total of eight. The project was started in 2010 and Ménard said more are planned for next year.

Although the project — which started in 2010 — is organized by the Maisonneuve Longue Pointe Eco-Centre, volunteers actually do the landscaping.

"They're the ones who are going to build the boxes that the flowers are going to be in," said Anne Gosselin from the centre. "They're going to be planting trees, They're going to paint the streets."

Gosselin said the alleys have been a success and help to mitigate heat coming from the asphalt.

"They offer a nice place for people to spend time," she said.

And it is residents who get to decide which alleys will be greened, Gosselin said.

Mercier-Hochelaga-Maisonneuve isn't the only neighbourhood looking to make its thoroughfares a nicer place to be.

On July 6, the nearby borough of Plateau-Mont-Royal, also said it would invest $137,000 to build five eco- and citizen-friendly alleyways.

There are similar initiatives throughout Montreal, and a total of 100 streets have been transformed into green space.

urban restoration

Green Apple Corps: Ecological Restoration with NYC Department of Parks and Restoration

The Green Apple Corps works to restore natural areas throughout New York City by doing intensive, hands-on ecological restoration work in the more than 12,000 acres of undeveloped parkland managed by New York City Department of Parks and Recreation. Corps members remove invasive and exotic plant species from forests, meadows, marshes, and freshwater and coastal wetlands, while helping to re–plant degraded areas with native species. Corps members also work to slow down erosion of slopes caused by inadequate drainage as well as foot and bicycle traffic, using cribbing techniques and materials that are designed to blend in with the natural surroundings. Additionally, throughout the program, Corps members take on exciting projects such as installing green roofs, building rainwater harvesting systems, and spearheading community plantings and coastal cleanups.

The GreenApple Corps collaborates with several other restoration groups, including Parks’ Natural Resources Group, Prospect Park Alliance, Central Park Conservancy, Grow NYC and the Gaia Institute. The combined efforts of the GreenApple Corps and its collaborators allow for increased amounts of ecological restoration work to be done, while also giving Corps members the opportunity to learn from practitioners with years of field experience.

roof top garden in georgetown

An Urban Meadow: Georgetown's Hidden Rooftop Garden

- Garden in the Sky -
High above the bustle of Georgetown, an unusual rooftop offers condo residents a prairie of their own.

By Adrian Higgins, Washington Post
Sunday, September 20, 2009

Tom Carroll pulls up the birdsong application on his iPhone, summons the call of a song sparrow and points the device to the meadow that starts about 20 feet from his home.

Sure enough, after a minute or two, an actual song sparrow starts calling back to the digital one. This might be little more than an endearing party trick if Carroll and his wife, Dora Marcus, lived on the edge of a field in, say, upper Montgomery County. But they live a little farther downstream on the Potomac River, in the shadow of Key Bridge. The meadow, perhaps Washington's greatest secret garden, is perched atop a Pepco electrical substation on the Georgetown waterfront.

The straw-colored flower heads of a grass called calamagrostis are just visible for the most observant of motorists on the Whitehurst Freeway, and pedestrians on Key Bridge might glance back to see the fuzzy-topped brick substation, but there is no real public vantage point to view the full sweep of this prairie in the sky. This paradox is heightened during rush hour, when the freeway, Key Bridge and M Street NW are filled with weary drivers unaware of the meadow floating above them.

The grasses give movement in the slightest breeze: The calamagrostis sways like pennants on wires on the meadow's southern edge, and the molinia stems shimmer veil-like on its western side. From high summer into fall, the full meadow goes through subtle color gyrations.

For Carroll and Marcus and their neighbors, the garden presents layers of color and texture, and a kinetic quality augmented by the birds. Mallard ducks, doves, sparrows, goldfinches and other species find both refuge and food here. In this 10,000 square feet of meadow 42 feet in the air, they thrive unmolested by cats, raccoons, people, snakes or floods. Only landscapers have access to the plants, and they must use long ladders. "Nobody picks the flowers," said Marcus, chuckling. And yet from their fifth-floor, two-bedroom condo, it's almost as if you can reach out and stroke the grasses.

Look to the right, and the meadow forms the ground plane for a view of Key Bridge with the Rosslyn skyline behind. Look downriver, and the garden frames a vista of the Potomac curving before the Watergate and the Kennedy Center. With the balcony door open, the apartment is filled with the whooshing of cars on the Whitehurst Freeway and the growl of jets twisting their way to Reagan National Airport. Close the door, with its soundproofed glass, and the scene shifts to one of surreal silence. The calamagrostis continues to dance.

Marcus and Carroll live in the plush condo building known only by its address, 3303 Water Street. The nine-story building is sandwiched between the freeway and the C&O Canal, and contains 72 apartments. It looks like a converted factory or warehouse but is only five years old and stands on a site that used to be occupied by electrical transformers and a canalside hill.

**********************************************

The garden was planted and is maintained by Washington Landscapes, whose owner, Peter C. Dickens, lives in the condo building, though his view is of the C&O Canal. His 10-member crews spend a day on the roof each month between March and December. The gardeners gain access with long extension ladders tethered to the roof's parapet. Wearing rock-climbing gear for safety, they use ropes to move material on or off the roof. They check the irrigation system and hand-pull weeds and any little trees that the birds have brought in. All the dead top growth of the grasses and perennials is cut and removed in late winter. Maintenance is funded by the residents' condo fees.

In the spring, thousands of daffodils sway in the April breezes. By June, the herbaceous plantings provide a textured carpet of green against the rose pink drifts of Nearly Wild and the oranges and yellows of daylilies. By July, flowers erupt for a summerlong display, including the wispy violet blossoms of the Russian sage, the golden black-eyed Susans and the azure blossoms of the chaste tree. The roses just keep blooming.

When visitors see the meadow "they say you've got your own Serengeti," Marcus said. "They can't get over it."

Chimney Swift Towers (Winnipeg)



Some very interesting projects to help establish new habitat for chimney swifts:

Stevens Point Sculpture Park - Stevens Point, Wisconsin

The Stevens Point Sculpture Park is working in partnership with the Aldo Leopold Audobon Society to develop and install two or more sculptural objects that can function as chimney swift nesting towers.

Call for Entries - Sculptural Chimney Swift Habitat


Nature Manitoba - Chimney Swift Program - Winnipeg and Surrounding Area


From 2006 to 2011, the Manitoba Chimney Swift Initiative received funding from the Manitoba government’s Sustainable Development Innovations Fund (SDIF) and from Environment Canada’s EcoAction Community Funding program. The project has also received support from Manitoba Hydro and other institutions.

In 2008, swift towers were erected in Starbuck, St. Adolphe, Portage la Prairie, and Winnipeg. In addition to watching these sites, the group continues to identify and monitor roosting and nest sites around the province.

Urban Wetland Art (in Toronto)



From Wet Kit:

The Canadian Plastics Industry Association commissioned Noel Harding, to create "The Elevated Wetlands:" a plastic-based, functioning, ecological sculpture. The initiative informs the public of the usefulness, resourcefulness and aesthetic appeal of recycled plastics. "The Elevated Wetlands" is located right beside the Don Valley Parkway, one of Toronto's busiest highways next to the Don Mills Road exit and the Don River.

Solar-run pumps draw water from the polluted Don River into the ponds below the six raised plastic "planters." The water is pumped from the ponds to three of the planters where it flows into three others. The structures use a recycled plastic "soil substitute" to promote vegetative growth that isolates and retrieves wastes, toxins and other impurities from the water. The project was inaugurated on October 1, 1998.

new discoveries in Ottawa!


Canada Lands Company purchases CFB Rockcliffe, Ottawa

Cannot wait to see what they come up with here!

Update December 2011: There is now a project coordinator listed and this description on the CLC website:

"The 310 acres (125 hectares) of the former Canadian Forces Base Rockcliffe, so close to Ottawa’s downtown core, present a once-in-a-life-time opportunity to discuss and address issues of urban reintegration, quality of life and factors important in designing the place where you live, work, learn and play.

The mission is to develop an exemplary diverse contemporary neighbourhood offering a choice in housing, employment, commercial, institutional and leisure activities which will be defined by the site’s unique setting, along with a commitment to environmental sustainability and long term economic viability.

The company will now activate a development process of the site, beginning with assembling a team of professionals. CLC looks forward to renewed consultations with the community and the City to create a vibrant mixed-used sustainable neighbourhood. More will be said about this as CLC’s development team and the consultation process takes shape over the coming months."



I'm also thrilled to have found out about the Montfort Woods!

From 90 wpm @ F22: "The Montfort Woods is a 9-acre wooded area located between the Montfort Hospital and the former Rockcliffe air base in east-end Ottawa. Originally owned by the Sisters of Wisdom, it was acquired in the 1990's to DRC Phoenix, a real estate developer. An application for re-zoning of the land was filed and granted by the City of Ottawa in 2002, allowing DRC Phoenix to build 258 townhouses on the land.

Local citizens and community organizations mobilized; the fate of the woods remained uncertain for the next two years. The National Capital Commission got involved by proposing a land swap with DRC Phoenix, whereby Phoenix would get Moffat Farm along the Rideau River in exchange for the Montfort Woods. The Moffat Farm project was ultimately rejected by the City, but the Montfort Woods remains the property of the National Capital Commission. The land was declared an environmentally sensitive area in September 2004, which rules out any future applications for re-zoning."

Ottawa Urban Wild Tours 2011


Series of five summer Urban Wild Tours in Ottawa are complete!

What a great summer we had with attendance ranging from 15 to 80 people on various tours. The support people showed for the tours was incredible! We were so thrilled with the turnout (both families and individuals) and the interest that everyone had in the great tour topics.

It was a pleasure to work with Julie who had the inspiring idea and recruited others to bring about these tours. With her creativity, enthusiasm and talent these events were easy to organize and she showed such dedication to seeing them through. And her design and graphic work gave these events such a professional online presence.

Working with all five tour guides who volunteered their time was a thrill. It was wonderful for them to share their knowledge and their love for the urban wild and their individual focus on specific flora and fauna topics. We were so lucky to find such passionate and informative guides.

Thanks so everyone for a wonderful summer!

amphibian habitat study (Ottawa)

The Geomatics and Landscape Ecology Research Laboratory at Carleton University has also done a conservation study on amphibians to determine the effect of road and land use around local ponds and the effect they have on frog and toad populations.

You can read more about the conclusions of their study and the recommendations in the following online brochure.

A short summary is: Terrestrial habitat of up to 2 kms around breeding sites (ponds, wetlands and wet forests) needs to be conserved along with networks between breeding sites (corridors). Reduced traffic along roads within these boundaries is key. Both forest and open space are important to have a diverse frog and toad population in urban/suburban areas.

Unique ecosystem in Ottawa

Did you know that Ottawa has a sand dune ecosystem (that has existed over 10,000 years)? Did you know that it is shrinking every year? Ottawa could lose this sand dune for good within 10 - 15 years.

But there is good news:

A restoration effort is being carried out by Biodiversity Conservancy in collaboration with the National Capital Commission and funded by the Ontario Trillium Foundation to restore the remaining part of the SSD system to a sustainable level. The restoration includes making a scientific assessment of orgsanisms living in SSD, removing weeds, selected trees, accumulated organic material, and cleaning the sand in the core of the remaining dune to stabilize the system. A corridor of woodland will be maintained around the perimeter of the SSD to minimize erosion by wind and to contain the sand in the dune.

For more information on this important biodiversity project go to the Biodiversity Conservancy website. They also have a Biodiversity Journal which they publish four times a year.

bears in urban areas


Bear and Human Interaction:

"People often mistake a bear clacking his jaws as threatening, but he is really saying "get out of here, leave me alone and don't hurt me," Stringham said.

Non-threatening behaviour and sensitivity to body language usually defuses the situation, he said.

Some cities are now ensuring there is a green corridor so lost wildlife can be escorted out of town, he said."


Read more here.

To study or to act:

"Still, $3 million (for a bear census on Kenai Peninsula) would buy a lot of bear-resistant garbage cans and fund a significant outreach campaign to educate the public about decreasing bear attractants. That may be a better use for the money, Selinger said. As much as he’d like to have an answer when people ask how many bears there are on the peninsula, he’s hesitant to be enthusiastic about a census without knowing how valid that result would be."

Creek Rehabilitation (Ottawa) CBC News Article

Ottawa looks to protect waterways from run-off

Pinecrest Creek rehabilitation to be pilot project aimed at waterways affected by development


CBC News
Posted: Jul 30, 2011 9:56 AM ET

The City of Ottawa wants to rehabilitate an urban stream in the west end that frequently floods because of surrounding developments, and says the plan could be a template for similar streams in the city.

Pinecrest Creek, a four-kilometer-long tributary that flows from Algonquin College into the Ottawa River, can rise by more than two metres after a rainstorm, ruining the shoreline and killing the aquatic life.

Jennifer Lamoureux, a biologist with the Rideau Valley Conservation Authority, says the conditions also mean that oil, salt and pet feces run from neighbourhoods into the waterway after rainstorms and eventually the Ottawa River, just upstream of Westboro Beach.

"It does get into Pinecrest Creek," she said. "There is very little control, if any, as far as filtration."

To deal with the creek's woes, the city is working on a proposal that will be released this fall. Dixon Weir, Ottawa's general manager of environmental services, says the report will encourage property owners to take responsibility for their stormwater run-off.

The plan may include incentives for rain barrels and perforated parking surfaces.

Weir says it's a pilot project that could become a template for managing other urban streams.

"This is a key learning opportunity for the city, and also for the residents, to understand better their impact and their positive contribution and influence they can have on the environment," he said.

************************

Since 2008 the National Capital Commission has been improving the creek's capacity to handle storm water run off and trying to lessen bank erosion:

"The NCC will undertake with the support of the City of Ottawa work to restore sections of the creek experiencing severe erosion or degradation to a fully-functioning, natural system. The proposed approach follows natural channel principles that enhance fish habitat while mitigating erosion forces. The following modifications are proposed at many restoration sites within the 2.3 km natural creek channel to help the creek system deal with erosion due to increased flows and steep hydrographs:
- Increased channel capacity and increased access to adjacent floodplain areas by the use of proposed floodplain pools, cutting back the channel side slopes, and the creation of shallow floodplain benches;

- Reduce flow velocities by the use of proposed meander pools, mid-channel low flow channels in exposed bedrock areas, in-stream anchor boulders, and modifications to channel widths;

- Reinforce bank stabilization in high impact areas; and

- Clearing of channel blockages, such as sediment and woody debris accumulations, channel protrusions which obstruct flow, and mid-channel bars which deflect flows.
Nine restoration sections, with a total combined length of approximately 670 metres of the 2.3 km of open channel, are proposed for restoration. Modifications will result in approximately 635 cubic metres of additional channel capacity."

replanting of an acreage in southeastern Manitoba

Silver Plains Project

From the website:

The plan for the Silver Plains Project combines elements of restoration, revegetation, and wildlife planting. We are gathering seed from the surrounding area (or obtaining it from vendors and acquaintances whose sources are nearby). We look forward to the day when the yard is low-maintenance. We have already seen an increase in native fauna: mostly insects, but also many birds.

While this replanting is close to being a restoration it can’t really be called that because species from many components of the Tallgrass Prairie ecosystem are being compressed into two hectares, including species for an artificial wet meadow which will not survive (in dry years) without someone to turn on the water. This planting might be considered revegetation or a wildlife planting except it is a yard, not a pasture or a uninhabited field.

***********************

From "Amended Toronto Green Building Standards Retain Bird-Friendly Measures" (November 2009)

"Council left intact existing green standard measures aimed at preventing bird-building collisions.
Window glass on new constructions must still be treated with a density pattern of between 10 and 28 centimetres apart or otherwise be able to mute reflections for at least the first 10 to 12 metres of a building, above grade.
 
The same goes for a requirement that builders ensure ground-level ventilation grates have a porosity of less than two centimetres by two centimetres.
 
Council adjusted new reduced light pollution targets “to make them a little clearer,” Welsh said.
New constructions and properties must reduce nighttime glare and light trespass, exterior light fixtures must be shielded to prevent glare or light trespasses onto neighbouring properties, and the city no longer allows up-lighting from exterior light fixtures unless a heritage designation applies.
The City has also added one requirement. When green roofs are built adjacent to glass surfaces, the glass must be treated to at least 12 metres above roof-level.
 
“We did a study on migratory birds and that was one of the recommendations from the study,” Welsh said. "

three levels of stream restoration & riparian buffers


Stream restoration images (before and after) from Natural Resources Conservation Services Website (U.S. Dept. of Agriculture)

Three Levels of Stream Protection:

1. To restore a stream means to re-create meanders, stabilize soil and install gently sloping stream banks. Stream restoration is not always possible due to constraints such as utility crossings, structures or roadways.

2. To enhance a stream is to attempt meanders and gentle slopes where possible and to stabilize the soil.

3. To stabilize a stream is simply to secure the stream banks from further erosion because constraints limit other degrees of stream protection.

From: Charlotte-Mecklenburg website



Riparian Buffers:

A riparian buffer is the forested area next to a body of water that serves as a protective strip against pollutants and erosion. The establishment of a riparian buffer is actually one of the most effective and important steps to restoring a stream and should be incorporated in stream restoration projects whenever possible. Many considerations should be taken into account when implementing a riparian buffer, but with some small amount of guidance, the average homeowner can improve the short-term and long-term health of a stream greatly and with less of a monetary investment than other stream restoration techniques.

When designing a riparian buffer, consideration should be made to use native, site-appropriate species (fitting light, soil and moisture requirements). Also, the riparian buffer should be designed to include all levels of the forest canopy (this includes large trees, shrubs, herbaceous material and native grasses). Riparian buffers serve many functions for a stream such as reducing nutrient inputs, reducing stream bank erosion and the subsequent sedimentation, reducing thermal pollution, providing habitat to aquatic and terrestrial species, and providing a food source for aquatic macro-invertebrates. While serving all of these functions, riparian buffers can also be aesthetically pleasing, incorporating wildflowers and budding trees.

Riparian buffers can provide many long-term ecological functions for a stream ecosystem while requiring minimal effort to implement.

roosting crows and supportive urbanites


Amber of Unstuffed Blog posted earlier this spring about the editorial regarding the crows of Alta Vista (Ottawa). What was heartening was reading some of the comments supporting the crows...

Rivereview park alumnus
9:13 AM on April 6, 2011


It is disappointing to see the "kill them" attitiude whenvever there is a conflict between wildlife and humans. I lived in Riverview Park for 15 years up until a year ago. Yes there are lots of crows compared to other areas. So lets find ways of working with the influx of crows. We have adapted to ever increasing numbers of people. A little balance is what is called for. It may be we have to adapt to the increased numbers. Crows aren't "creepy". That is an attitude that needs adjustment. If you take the time to get to know crows, they are fascinating - smart, loyal to their families and resilient. They are ominvores just like people. I think more education on efforts to co-exist would go a long way to helping the problem.

Well, I live right next door to those ol'crows at Baleena Park. In fact, I go to work around the time they are just getting up and starting to move about...I have yet to step in any poop, despite occassionally seeing some on my truck,which could have been left by the one of the large number of sea gulls in the area.

At night when the crows "come Home" from their day of scavaging and eating garbage it's cool to see them come into the neighbourhood in small squadrons all lining up on the roof tops waiting for their turn to park for the night in one of the tall trees.

In the morning, even though they can be a bit loud, it's cool to see them circling around and heading off to their business......Leave the crows be you anti-nature creeps and learn to enjoy what little nature is left in your city-ass lives!

Sheesh some poeple are just jerks.....

What's with the idea of tying an owl to bait crows ?
Or people suggesting we open shooting contests ?
Or culling geese ?
Or poisoning crows ?
Seriously, folks suggesting that have personal issues.
Is that how you treat people also ?

Can't anyone here just enjoy nature anymore ? Respect people and animals around them ? Not be violent ?
Ottawa used to be nice with the greenbelt, the surrounding woodlands and fields, the geese and birds and swans. It was a great and safe place to bring up kids with people who enriched lives rather than trying to take them away.
What happened ?

It is very true that it is a necessity to clear crows away from areas where they can cause damage, and endanger people's lives, but is the best idea that the City Councillor can come up with for protecting the hospital helipad really one that involves torturing an innocent owl?

And how much of a necessity is it really to clear them completely out of the neighborhoods? Because they get into garbage bags? We have to protect our garbage from racoons anyway. Is the bird poop really a big issue? I see the great flocks of these birds everyday when they are roosting in the trees, flying overhead, and walking in the grass, but I have yet to notice any bird poop.

The presence of these birds does bring joy and pleasure to some people, who like to see a bit of wildlife where we live, to remind us that we are not just machines living on a paved earth. Do we really need to destroy a great part of nature just because it provides a slight inconvenience to some?

I live near a crow's roost, and I can't believe what I am reading. I have never once considered them a nuisance.

I get that we need to keep them away from the helicopter pad, although the method seems very cruel to the owl. But other than that, people are just being silly.

The crows are fascinating to watch,and they do a fabulous job of cleaning up the neighbourhood of small dead animals, of which there is usually an abundance. We are also overrun with squirrels, bunnies,and field mice. Which, by the way, is what likely attracts the crows to these areas.Not to mention they clean up some of the garbage the filthy humans leave lying about.

I am overjoyed to feel like I can live amongst nature so close to the city centre. I don't get that the crows, or any other animal, are a nuisance (except when safety is a factor).

Neighbours who make a pastime out of complaining, now them, I would like to get rid of.

Owls will attract agressive attention from a large murder of crows. i wouldn't want to be the owl that gets this job.

Nobody complained when people built houses on the crows homes. The crows are just returning the favor!

"Dear Residents of Alta Vista, We're not sure about how you redecorated our forrest, but thanks for all the garbage.

Love,
The Crows"

make your voice heard for biodiversity

BIODIVERSITY CHARTER

Ontario Nature’s goal is to generate 10,000 signatures by the 22nd of May 2011 (which the U.N. proclaimed as the International Day for Biological Diversity) to request that federal, provincial and municipal governments to take action and stop the loss of Ontario's biological diversity by 2020. Right now they have over 5000 and a little over 10 days left. Why is it important for us to protect the biodiversity that we have in Ontario (and in the rest of the world)?

"Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example,
- A larger number of plant species means a greater variety of crops
- Greater species diversity ensures natural sustainability for all life forms
- Healthy ecosystems can better withstand and recover from a variety of disasters."
(Quote found here.) The continual increase in human population has meant a larger encroachment on wilderness every year - whether it's for dwellings, food or resource extraction. We may be on our way to the next mass extinction. It's up to us to protect what is left and enrich what we can.

Please sign the charter at Ontario Nature's website.

SLOE - Rideau River herptile survey (ottawa)

Reptile and Amphibian Survey

Sustainable Living Ottawa East is hosting its first reptile and amphibian survey along the Rideau River Nature Trail. The goal is to discover the rich diversity of reptile and amphibian species living in the community, so further action to protect these species can be taken as well as to preserve the health of the Rideau River shoreline. This event will also help SLOE build stewardship within the neighbourhood. This event will be a fun and educational experience for the whole family.

Sat May 14, 9 am - 12 pm and 9 - 10 pm.
Sat Jun 18 9 am - 12 pm and 9-10 pm.

For information and if you want to participate, contact Jess Pelow

bioengineering for stream restoration


From the R.V.C.A.:
Bioengineering is erosion control using live cuttings of willows and dogwoods to help stabilize banks and revegetate shorelines in areas where tree planting will wash out. It is an alternative to using harder structures, such as rip rap, gabion baskets, armourstone, etc. Layers of soil are wrapped in coconut fiber to hold them into the bank. Live cuttings of willows and dogwoods are used to create a fascine (tubular structure) placed along the water line, and live cuttings are then placed between the layers of wrapped soil. Shrubs are then introduced at the top of slope.
Link to Ontario Streams for a more detailed description of fascines.

Here is a link to a report on a bioengineering project for Graham Creek in Ottawa.

Read this 2011 post about riparian buffers and the three levels of stream restoration.

bird skyscraper design (Chicago)

Found Online:

September 17, 2009


A skyscraper for the birds: Aqua gets an award from animal rights group

Chicago architect Jeanne Gang's 82-story Aqua tower (left) isn't done yet, but PETA (People for the Ethical Treatment of Animals) is giving Gang and her firm, Studio Gang Architects, an award for the bird-friendly design of Aqua. The group says that birds are less likely to kill themselves flying into Aqua's windows because of the skyscraper undulating curves and because its exterior glass is etched with marks that birds will be able to see.

"The American architect Louis Sullivan coined the phrase 'form follows function,'" PETA's president, Ingrid Newkirk, says in a news release. "In the Aqua Tower, form follows compassion."

Vertical Garden City projects (by Mori)


Urban Design Consultant: Mori (Japan)

From their website:

Adopting the “Vertical Garden Cities” as our redevelopment concept, one of our primary missions is to build environmentally friendly cities rich in greenery, striving to maximize open space and “green” the cityscape. Through intelligent consolidation and redevelopment of densely developed areas and the building of high-rise buildings to free surface land for greenery and by taking proactive steps to “green” the buildings with roof gardens, we are able to create numerous corners of nature within the city.
