When zookeepers discovered that flamingos need a large flock in order to breed, it led to all kinds of crazy approaches to fool the birds – mirrors, plastic yard ornaments, speakers playing bird-crowd sounds (now, zoos generally just keep more birds). I think of habitat loss and fragmentation like a flock of flamingos. There’s a certain amount required for the habitat to function properly. If the size is too small or divided, it will fail.
The Atlantic Longleaf Pine Ecosystem (a.k.a. pine barrens – a deceptive name considering the high amount of biodiversity) spanned over 35 million hectares (about the size of Germany) around the year 1500; today, only ~1 million hectares of pocket forests remain. (1)
Good news though! If habitat is restored, amphibians (including our friend, Mabee’s salamander), among many other species, come back too. (2)
