This the Ecology Park in Greenwich, it was built as part of Millenium Village scheme, that looks at quality of life and sustainability. theirs so much going on within this area i could babble on for ages. a site definatley worth looking at, it seems as though they've covered every thing that needs to have been covered, this tiny park gives home to bats, native and non native birds, loads of insects. They have also seen some species of dragon fly that have been extinct in london for several years, the whole ecosystem is amazing. what makes it better is the size of the park and the way one habitat co-works with another. they consider season to season, speceies to species, even the levels of water within ponds are crutial. Very good scheme to look at.
