Lush climates alone do not account for the vast biodiversity in tropical rainforests. Research on treefrogs from around the world, covering 123 sites and gathering DNA sequence data for 360 species of treefrogs, has provided a new understanding of biodiversity in tropical rainforests: some groups of treefrogs have existed together in the Amazon Basin for more than 60 million years. A more recent publication supports this finding, noting that forests in Canada and Europe may have much more in common with tropical rainforests than previously believed, but tropical forests have not been subjected to glaciations and mass extinctions, allowing for much greater biodiversity.

Cryptoforestry is a heady blog that covers cryptoforests of all sorts, from feral forests that thrive next to heavily developed urban environments without human assistance, land in limbo and "states of vegetation for which lay-language has no name", incognito forests that hide in plain view, precognitive forests that are about to become forest or are forest Fata Morgana, and unappreciated forests that are considered wastelands. The scope of the blog covers local Utrecht sites to the "g/local" Amazon basin, and lands in-between. All this is filtered through the lens of psychogeography, emphasizing "the psychological effects of a forest rather than canopy cover or land use as of importance for classification." [more inside]
