One puzzled them, and a curator was called to identify the large, long-legged wetland fowl as a purple swamphen – the creature that supplies the title for Lively's latest book, The Purple Swamp Hen and Other Stories (Fig Tree).
As with all other long-term wetland evolution studies12,13,14,15, this 20-year time step is a compromise between computational time and process description and is compatible with the slow dynamics of the system.
An ill-considered Supreme Court decision two years ago narrowed safeguards for certain isolated wetlands long covered by the law.
The long journey from wetlands to publication in a scientific journal required several steps to definitively show the distinctiveness of the new critter.

Julie Sibbing, a wetlands policy expert at the National Wildlife Federation, said, "It's like writing off the entire Southwest from the Clean Water Act, where water is more precious than in any other region of the country.

A member of the local community counted the number of animals at the wetland on a particular day each week for as long as the wetland held water.
Much of the flood plain has been given over to the Wyspy Swiderskie wildlife reserve on its east bank, with several sandy beaches and a long band of wetland abundant with wild flowers, butterflies, lizards, snakes, hawks and beavers – all thriving on the edge of the capital.
