Urban Forest Map (San Francisco)

The Urban Forest Map is a project in San Francisco, California that allows residents to enter information online by finding a tree on Google Earth, marking it and entering information regarding the street tree.  It's a great way to build an urban tree inventory through volunteer efforts.  This project is supported by governments, non-profits and businesses. It not only helps catalogue (with species, diameter at breast height and other info) the immense urban canopy the city has but it also provides data on the ecological services that the trees provide to the area. Check it out below:

Part of the reason this project was initiated was that canopy cover was extremely low (2.5% in 2008), and this inventory has helped underline this and show where new trees are most needed.  You can see all the trees in google map in either a street view or satellite view.  Pretty impressive!

Cornwall Eco Gardens

Did you know that Cornwall has an Eco-Garden? It can be found in the middle of Lamoureux Park and includes a small creek. It was built in 1997 and attracts many fish, birds and amphibians. The creek is key for spawning chinook salmon and the alternating shallow riffle areas and deeper pools have provided a home for cutlip minnow (which requires clear, silt-free streams to thrive).

The article goes on to say that smaller streams and creeks have improved in gaining back nutrients for the larger river, but more work still needs to be done. Rock reefs have been built along the river to create protected areas for fish to forage and nurse. The article also lists three areas where work is still continuing on the remedial action plan: contaminant levels in fish, decreases in levels of nutrients in smaller rivers and creeks, and fish and wildlife habitat, in particular coastal wetlands.
