U.S. Urban Tree Cover Down and other Remote Sensing News

Results indicate that tree cover in urban areas of the United States is declining at a rate of about four million trees per year, according to a U.S. Forest Service study of 20 U.S. cities published in Urban Forestry & Urban Greening.

Forest researchers David Nowak and Eric Greenfield of the U.S. Forest Service's Northern Research Station used satellite imagery to find that tree cover is decreasing at a rate of about 0.27 percent of land area per year in U.S. cities, which is equivalent to about 0.9 percent of existing urban tree cover being lost annually.

Conservationists are using UAVs to gather data to protect land, plants and animals.

Using seed funding from the National Geographic Society, The Orangutan Conservancy, and the Denver Zoo, Lian Pin Koh, an ecologist at the ETH Zürich, and Serge Wich, a biologist at the University of Zürich and PanEco, have developed a conservation drone equipped with cameras, sensors and GPS. So far they have used the remote-controlled aircraft to map deforestation, count orangutans and other endangered species, and get a bird's eye view of hard-to-access forest areas in North Sumatra, Indonesia.
