Fire managers are increasingly using natural ignitions to restore and maintain fire-adapted ecosystems. Managing natural ignitions after decades of suppression, however, holds inherent ecological, economic, and personal risks. During the severe drought of 2011, fire management staff on the Ouachita National Forest used a range of strategies to manage the lightning-ignited High Peak Wildfire becaus...
Subtropical China has a large area of Acacia mangium plantations; however, some key aspects of the structural and functional changes and the associated mechanisms after planting are still not well understood. We established a permanent plot in an A. mangium plantation and monitored the plant diversity (i.e., the number of species), biomass, soil physical and chemical properties and light transmitt...

Returning a site or landscape to some historical condition is a long-standing objective in restoration ecology, but restoration ecology is by no means limited solely to the goal of returning an ecosystem to a prior condition. Restoration, done properly, can increase biodiversity, restore structure and connectivity, and enhance a variety of ecosystem services that may better position ecosystems to ...
On November 3, about forty people from the USDA Forest Service and The American Chestnut Foundation (TACF) gathered virtually. It was the second biennial plan of work meeting between TACF and SRS. Since the 1990s, the two organizations have worked together on American chestnut (Castanea dentata) restoration. In 2017 and in 2019, they committed to […]...
New research has demonstrated how, in contrast to encroachment by the invasive alien tree species Prosopis julifora (known as Mathenge -in Kenya or Promi in Baringo), restoration of grasslands in tropical semi-arid regions can both mitigate the impacts of climate change and restore key benefits usually provided by healthy grasslands for pastoralists and agro-pastoralist communities....

In early 1953, eight blocks of the Southwide Pine Seed Source Study (SPSSS) featuring two geographically based series of shortleaf pine (Pinus echinata) were planted in Compartment 46 of the Crossett Experimental Forest (CEF). These shortleaf pines originated from Arkansas, Louisiana, Mississippi, Missouri, New Jersey, Oklahoma, Pennsylvania, Tennessee, and Texas seed sources. Their survival, fusi...
<p>Ecological restoration is central to the wellbeing of Indigenous communities, who have tended, burned, and harvested a variety of resources across diverse ecosystems in California for millennia. Despite having more tribes and more Native Americans than any other state, California has less land under tribal control than most of the states west of the Continental Divide. Consequently, tribe...
Watershed assessments have become common for prioritizing restoration in river networks. These assessments primarily focus on geomorphic conditions of rivers but less frequently incorporate non-geomorphic abiotic factors such as water chemistry and temperature, and biotic factors such as the structure of food webs. Using a dynamic food web model that integrates physical and ecological environmenta...
