Every city has acres of in-between land that, if managed well, could become oases of greenery harboring insect, bird and other animal life.
The rubble-strewn cities of the Second World War, to the astonishment of their inhabitants, very quickly brimmed with plant and animal life.
In central Münster, Germany, piles of rubble were veiled with spontaneously growing pussy willow, mountain maple, birches, yellow mulleins and wild strawberry.
Neglected sites were profuse in biodiversity, often containing many more species of plants and insects than nearby parks or even the countryside.
Like the Great Trinity Forest, first it was abandoned and then hundreds of species took over, many of them endangered.
