Just a short hike into a 200-acre woodland in Manhasset lie a series of shallow basins in the forest floor left behind by retreating glaciers. After a dry August, the basins are empty, but in spring they will fill with snowmelt and rain and teem with wildlife: spotted salamanders and wood frogs, waterthrushes and rusty blackbirds, woodland bats and a resident pair of coyotes. Small freshwater wetlands like this provide habitat for dozens of species, offer protection against flooding and help cle

Invasive plants are undermining the health of Long Island's forests. Home gardeners can help control them.

On a muggy day in late August, George Jackman, an aquatic ecologist who works on habitat restoration, stood at the edge of Quassaick Creek in upstate New York.

For 300 years, that torrent had been contained by a small dam that once powered a nearby mill, where the
