Mangrove expansion has been observed in some subtropical locations around the world.

Scientists at the University of Georgia’s Marine Institute at Sapelo Island have found that the amount of vegetation along the Georgia coast has declined significantly in the last 30 years, spurring concerns about the overall health of marshland […]

In western North America, mountain pine beetles infest and ravage thousands of acres of forest lands. Landsat satellites bear witness to the onslaught in a way that neither humans nor most other satellites can.

Since record keeping began in 1860, no period has been drier for southeastern Australia than the decade-long Millennium Drought. The lack of rain between 1997 and 2009 led to livestock losses, crop failures, and percentage drops in the Australian GDP.

NASA and the U.S. Geological Survey’s Landsat satellite images over the past three decades showed that the severe drought periods recorded since the 1980s have not slowed rapid tree and shrub growth, especially on steep slopes burned recently by […]

The BirdReturns program, created by The Nature Conservancy of California, is an effort to provide “pop-up habitats” for some of the millions of shorebirds, such as sandpipers and plovers, that migrate each year from their summer breeding grounds […]

A NASA-led team of scientists has developed the first-ever method for detecting the presence of different types of underground forest fungi from space, information that may help researchers predict how climate change will alter forest habitats.

Across the U.S. and particularly in Washington state, very little is known about the acreage, yearly flooding cycles and even the actual locations of wetlands. Even hazier is what could happen to these vital ecosystems under climate change.

A marriage in the remote forests of China promises to unite two important forces to better inform the health and future of biodiversity. The union is reported in this week’s journal Ecological Indicators by Michigan State University researchers.

A new Landsat-based report from the USGS St. Petersburg Coastal and Marine Science Center takes an integrated look at barrier islands.

Alex Riter, a graduate student at the University of Maryland College Park, presented her finding on how Hurricane Sandy affected New Jersey coastal marches at #AGU15. We talked to Riter about her research.
