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 

Estimating Ecosystem Water Use

For more than a decade, U.S. Forest Service and Chinese scientists have collaborated to understand how human activities affect carbon and water cycles in managed ecosystems. Working through the U.S.-China Carbon Consortium, scientists share data from a network of eddy covariance flux towers across the two countries. The towers measure the flow of water vapor,…  More 

In the Amazon Rainforest, Small Roads Have Big Impacts

Cars, trucks, and other vehicles leave noise, pollution, and roadkill in their wake. But if those impacts are subtracted, what about the roads themselves? “We wanted to untangle the effects of a road from the effects of driving vehicles on that road,” says U.S. Forest Service scientist Daniel Saenz. The issue is especially important in…  More 

An Assignment in Africa Connects Forests, Water, and People

Steve McNulty, Ge Sun, and Erika (Cohen) Mack hiked for three hours on a winding trail over steep hills through land thick with trees and vines. They arrived at a pool and looked up at a towering waterfall. If they had stood at the top of the waterfall, they would have seen forested land stretching…  More 

Dry Tropical Forests in the Caribbean and Latin America under Threat

The climate and fertile soils of the dry tropical forests of Latin America and the Caribbean have been important to humans as areas to grow crops since pre-Columbian times. Because of this and more recent use for intensive cultivation and cattle grazing, many of these forests have been cleared, with less than 10 percent of…  More 

A Stoplight Tool to Enhance Communication of Forest Landscape Restoration

Today finds U.S. Forest Service scientist John Stanturf in Portland, Oregon, sharing the “spotlight tool” — a framework he and international collaborators developed to assess forest restoration projects in relation to climate change adaptation and mitigation — with communicators from all over the world participating in a joint workshop of the UNECE-FAO and the International Union of…  More 

Little Rock Hosts International Silviculture Workshop

On May 31st, over 50 researchers from the United States, China, Germany, Slovenia, Chile, Germany, Poland, Finland, the Czech Republic, Switzerland, Canada, Belgium, and the United Kingdom descended upon Little Rock, Arkansas to discuss forestry management techniques from around the world at the 10th International Workshop on Uneven-aged Silviculture. Jim Guldin, project leader for both of…  More 

Landscape Ecology Meeting Draws Forest Service Scientists and Record Attendance

After more than a year of planning, local organizers from the U.S. Forest Service Eastern Forest Environmental Threat Assessment Center were thrilled to finally welcome attendees of the annual meeting of the U.S. International Association for Landscape Ecology (US-IALE), held last month in Asheville, North Carolina. It was the 29th annual and the largest ever…  More 

Santee Experimental Forest Chosen for U.S.-China Climate Change and Forests Initiative

U.S. Forest Service Southern Research Station scientists and the Santee Experimental Forest (Santee) located in the Francis Marion National Forest near Charleston, South Carolina, have been chosen to participate in the U.S,-China Climate Change and Forests Initiative, a new program  of the U.S.-China Climate Change Working Group sponsored by the U.S. Department of State. The U.S.-China…  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
