Kahuku Plant Inventory at Hawaii Volcanoes National Park - This inventory identified vegetation communities and located rare, threatened and endangered plants, as well as disruptive alien weeds. Forty-one kilometers of transects and 177 vegetation plots were ground-surveyed; 6.5 hours of helicopter surveys were conducted. A total of 455 vascular plant species were encountered, of which 40% were native. Five endangered, one threatened, one candidate endangered, seven species of concern, and 26 locally rare native species were found. Results from this study will enable managers to develop a framework for long-term management priorities and strategies in Kahuku which was added to Hawaii Volcanoes National Park in 2003.

Ecological Diversity at Blue Ridge Parkway - For a park that was created primarily for scenic and recreational purposes, the Blue Ridge Parkway possesses one of the most diverse assemblages of ecologically significant communities in the Eastern United States. During vegetation mapping and plant inventories conducted by the Appalachian Highlands network, 75 distinct plant communities (associations) were documented within the park; 24 of these are considered globally rare, and seven are considered globally imperiled. The variety of these communities ranges from very dry/xeric woodland slopes to cloud forests dominated by spruce and fir, to high-elevation wetlands that support boreal relict species as well as extremely rare southern Appalachian endemic species that occur nowhere else.

Bewick’s Wren Added to Chickamauga and Chattanooga National Military Park (CHCH) Species List - As part of its inventory and certification process, Cumberland Piedmont Network staff was able to add the Bewick’s wren (Thryomanes bewickii) to the CHCH park species list. This species, which was thought to be extirpated from the Appalachian region, has experienced precipitous declines throughout the eastern U.S. to the point where most states east of the Mississippi list it as ‘critically imperiled’ or ‘possibly extirpated.’  Reports of two adults feeding juveniles at the park represent the first breeding evidence in the region since the early 1980s.

Pika Found to Be Using Historic Locations - In FY 2007, a pika inventory and occupancy modeling study was conducted at Craters of the Moon National Monument and Preserve. Evidence of pika presence was detected at several historic locations and many new locations were recorded. This is significant given the growing evidence that pika may be vulnerable to climate change. Craters of the Moon may support a regionally significant pika population.

Fish Inventories Document Rare Species - Academy of Natural Sciences of Philadelphia conducted a fish inventory at Delaware Water Gap National Recreation Area and Upper Delaware Scenic and Recreational River. Several species that were previously considered to be rare or of uncertain status appear to be relatively widespread in the two parks (e.g., Eastern mudminnow, gizzard shad, northern hog sucker, bluespotted sunfish, bluntnose minnow, comely shiner, swallowtail shiner, and satinfin shiner). Combining 2005 and 2006 observations, bridle shiners, a very rare species, have been found at sites within Delaware Water Gap National Recreation Area and in NJ wildlife management areas.

Previously Undocumented Species of Reptiles and Amphibians Discovered - Amphibian surveys at Sleeping Bear Dunes National Lakeshore revealed four new species of reptiles and amphibians in the park. This work was part of the design phase for long-term monitoring of amphibians at the parks and was performed by herpetologists from the Chicago Field Museum.
