Prevalence of Batrachochytrium dendrobatidis in Eastern Hellbender (Cryptobranchus alleganiensis) Populations in West Virginia, USA
-
The eastern hellbender (Cryptobranchus alleganiensis alleganiensis) is a North American salamander species in decline throughout its range. Efforts to identify the causes of decline have included surveillance for the chytrid fungus Batrachochytrium dendrobatidis (Bd), which has been associated with global amphibian population losses. We evaluated the prevalence of Bd in 42 hellbenders at four sites in West Virginia, US, from June to September 2013, using standard swab protocols and real-time PCR. Overall prevalence of Bd was 52% (22/42; 37.7–66.6%; 95% confidence interval). Prevalence was highest in individuals with body weight ≥695 g (χ2=7.2487, df=1, P=0.007), and was higher in montane sampling sites than lowland sites (t=−2.4599, df=44, P=0.02). While increased prevalence in montane sampling sites was expected, increased prevalence in larger hellbenders was unexpected and hypothesized to be associated with greater surface area for infection or prolonged periods of exposure in older, larger hellbenders. Wild hellbenders have not been reported to display clinical disease associated with Bd; however, prevalence in the population is important information for evaluating reservoir status and risk to other species, and as a baseline for investigation in the face of an outbreak of clinical disease.

Purdue Agriculture Help the Hellbender
-
Everyone can do something to Help the Hellbender. On this website, you will find information about the hellbender, as well as household and farm management practices that can help keep our rivers and streams clean. People who fish and kayak can also learn what they should do if they see a hellbender in the wild.

The Hellbender is a giant, aquatic salamander that has experienced severe population declines throughout its range. It is a sensitive species and there are a number of factors contributing to its declines. To help address the varied threats facing the Hellbender, Help the Hellbender has produced several new products focused on educating both stakeholders and the general public on ways that they can help protect hellbenders.

Range-wide assessment of grazing and hydrology in bog turtle wetlands
-
In December 2018, a meeting of bog turtle experts was hosted in Richmond, VA and experts across the Eastern range of the species identified as a high priority the need to better understand the benefits and potential negative impacts of livestock grazing in bog turtle inhabited wetlands. Hydrologic conditions in bog turtle wetlands emerged as a secondary concern needing more research. Recently, NRCS’ Conservation Effects Assessment Project (CEAP) awarded funds to Dr. Carola Haas leading a team of researchers at Virginia Tech University to conduct an assessment on these two topics (grazing and hydrology).

Sagebrush Biome Framework
-
This framework for 2021-2025 reflects collaborative, multi-state planning efforts to update SGI 2.0, and continues to build from a decade of success conserving the sagebrush biome. This framework also serves as NRCS’ ongoing contribution to the Sagebrush Conservation Strategy administered by Western Association of Fish and Wildlife Agencies. Sharing common cross-boundary threats, NRCS staff across eleven western states collaborated to create this shared vision for conservation action.
