The Anthropocene
Here is the means to end the great ex0nc0on spasm. The next century will, I believe, be the era of restora0on in ecology". E.O. Conceptual approach HANDS ON APPLIED APPROACH Urban restora1on and the problem of legacy metals; Two examples (collabora1on with SFU and BCIT) 1) Beaver Lake 2) MacKay Creek Beaver Lake Stanley Park's interior oasis is Beaver Lake, a beau0ful wilderness full of trees, animals and plants, crea0ng a serene place to enjoy the Park at its finest. Its allure is its seclusion from vehicular traffic….. Rapidly filling in; quickly moving from a lake to wetland to meadow Si/ng on lake bo8om To restore the lake, then will likely need to remove accumulated sediment. Will it be safe to do so?
