This 72-page report answers the call for stronger ecological performance standards for guiding the wetland mitigation process. Here we present two methods for setting those standards: a) a watershed approach and b) an approach based on ecological integrity assessment methods.
The report presents the most detailed study of its kind ever carried out, in which scientists identified 12 previously unknown centers of endemism — areas that safeguard species found nowhere else in the world — in the Eastern Andean slope and Amazon basin of Peru and Bolivia. The report also illustrates distribution maps for 782 endemic species of plants, mammals, amphibians, and birds in unprecedented detail.
Kentucky’s Natural Heritage: An Illustrated Guide to Biodiversity provides an essential reference to the state's natural history and unique biological patchwork—a rallying cry for the conservation of this priceless legacy.
With environmental change wreaking widespread shifts in species distribution, some plant communities will likely disappear while entirely new ones will appear within our lifetime. This reality requires an understanding of the distribution of plants species and careful definition within a consistent typological framework.
This classification subset includes all alliances and associations attributed to any of the National Forests in Texas, including the Angelina, Davy Crockett, Sabine, and/or the Sam Houston. These attributions were developed after fieldwork on National Forest lands conducted with the objective of visiting representative examples of all the major vegetation types, rare or unusual communities, and vegetation resulting from common forest management regimes.
This classification subset includes all alliances and community associations attributed to the Kisatchie National Forest in Louisiana, as well as some for which more data are needed to confirm their occurrence. This report is intended for use by Forest Service personnel and other ecologists working in the area. Fieldwork took place primarily in 1994-1995, during the early life of this project.
This classification subset includes all alliances and associations attributed to the Francis Marion National Forest in South Carolina, as well as some for which more data are needed to confirm their occurrence. This report is
intended for use by Forest Service personnel and other ecologists working in the area. Fieldwork took place primarily in 2002 and 2003.
This classification subset includes all alliances and associations attributed to the National Forests of Arkansas (Ouachita, Ozark, and St. Francis), as well as some for which more data are needed to confirm their occurrence. This report is intended for use by Forest Service personnel and other ecologists in the area. The fieldwork for the Ozark and Ouachita National Forests took place in 1998. Additonal fieldwork on the St. Francis National Forest took place in 2002.
The U.S. National Vegetation Classification standard is intended as framework and a tool for conservation planning and biodiversity protection, as well as resource planning, management, and vegetation mapping.
With gypsy moth outbreaks expected to be a fixture among North America's forest ecology for the foreseeable future, this report lays out the factors which managers take into account in shaping their response.
