Putting Mangrove Data to Work in East Africa

Mangrove forests are among the most carbon-rich ecosystems on the planet. Their stilt-like roots trap carbon and other nutrients that rivers have carried to the coastal deltas where mangroves grow. They act as a buffer, protecting coastlines and the people who live there from increasingly strong seas and storm surges. People depend on mangrove forests…  More 

Mangroves of Mozambique

Whether small and shrubby or tall and majestic, mangroves have an unusual ability – they are specially adapted to grow in brackish water, and can tolerate ocean waves lapping at their stilt-like roots. As stands mature, soil and decaying plant matter becomes captured in the intricate web of their roots. “The soil in mangrove ecosystems…  More 

U.S. Forest Service Scientist Helps Establish First Mangrove Experimental Forest in Africa

Mangrove forests stabilize the tropical and subtropical coastlines of most of the world’s continents and provide valuable ecosystem services such as fish habitat and storm buffering. Unfortunately, mangroves are one of the world’s most threatened tropical forest ecosystems, with an estimated 35 percent of the forests already gone worldwide and others being cleared daily for…  More 

How Much Carbon is Stored in Mozambique Mangroves?

In an article published online in the journal Forest Ecology and Management, U.S. Forest Service researcher Christina Stringer and collaborators provide the first comprehensive estimate — 14 million megagrams (Mg) or almost 31 trillion pounds — of the carbon sequestered in the mangrove forests of the Zambezi River Delta in Mozambique. More important than the…  More 

Headwaters to Estuaries: Advances in Watershed Science and Management

On March 2 -5, 81  scientists, managers, and stakeholders met in North Charleston, South Carolina, to present and discuss the latest research on watershed science and management. U.S. Forest Service Southern Research Station scientist Carl Trettin served as conference chair and host  for the 5th Interagency Conference on Research in the Watersheds, which took a national perspective…  More 

Carbon Pools in African Mangrove Forests

The National Aeronautics and Space Administration (NASA) recently announced funding for a proposal that involves the U.S. Forest Service, NASA, Duke University, and the University of Maryland in using field-based research as the basis for developing remote sensing tools to assess and monitor carbon pools in African mangrove forests. The project will use advanced 3-D…  More 

A City’s Dynamic Mangrove Forest

A recent report by U.S. Forest Service researchers on the forests of the San Juan Bay Estuary watershed provides details about a highly dynamic urban forest that provides important benefits for its residents. Tom Brandeis, supervisory research forester with the Forest Service Southern Research Station (SRS) Forest Inventory and Analysis unit, worked with other Forest…  More 

Mangroves in Mozambique

September found U.S. Forest Service researchers Carl Trettin and Christina Stringer camping out on the edge of a mangrove swamp in Africa, watching the ocean tides for the best time to take their skiffs out to search for plots to set up for inventory. They were in Mozambique, which stretches along the eastern coast of Africa…  More 

Black Mangrove on the Move on the Gulf Coast of Texas

Some plant species are already migrating due to climate change, moving north into areas that aren’t as cold as they used to be. Along the Gulf Coast of Texas, black mangrove, a small shrubby tree, is expanding into saltmarshes as the intervals between winters with freezing temperatures lengthen. Easily outcompeting the Spartina cordgrasses that dominate…  More
