Grazing for Bog Turtle Habitat Management: Case Study of a New York Fen
-
This study presents results from a single wetland complex in New York, USA, which we managed primarily with cattle grazing over four and a half growing seasons. Management effectiveness was assessed by monitoring Bog Turtle nest placement, habitat use via radio tracking, and vegetation structure and composition change in permanent plots.

Importance of demographic surveys and public lands for the conservation of eastern hellbenders Cryptobranchus alleganiensis alleganiensis in southeast USA
-
Comparisons of recent and historic population demographic studies of eastern hellbenders Cryptobranchus alleganiensis alleganiensis have identified significant population declines and extirpations associated with habitat degradation, poor water quality and disease, leading to nomination as a candidate for listing under the Endangered Species Act. However, populations in the southern Appalachian region of the range have received less attention despite relatively high levels of watershed protection due to the establishment of federally protected National Forest and National Park public lands. These watersheds likely represent some of the best remaining available habitat, yet the lack of published studies make assessment of population stability and viability very difficult. Our objectives were to (1) conduct a capture-mark-recapture (CMR) demographic study and a point transect survey on the Hiwassee River in Tennessee which is designated a National Scenic River, and is largely contained within the Cherokee National Forest, (2) quantify the size structure of the population, (3) compare abundance, survival and recruitment with historic and contemporary hellbender populations across the range, (4) assess the importance of this population and the significance of National Forest and National Park lands in the context of hellbender population conservation in the southeastern United States. We detected all age classes present, with larval hellbenders comprising 21.5% of captures. Using a combination of static life table and CMR methods, we determined that survival rates during the first year were low (~10%), but were high (68–94%) for taggable sized hellbenders. Density of hellbenders at the study site was very high (84 taggable sized hellbenders per 100m of river) compared to recent demographic studies conducted in other regions of the range. We detected hellbenders over ~28 km of river, with a mean density of 23 taggable sized hellbenders per 100m of river, and a total population estimate of 6440 taggable hellbenders. National Forest and National Park lands are likely to continue to play a particularly important role in providing suitable habitat for hellbenders in the southern Appalachians. In fact, only six of 21 known hellbender locations in Tennessee appear to show consistent larval recruitment, all of which are located within or adjacent to National Forest or National Park land.

Improving the Utility of Artificial Shelters for Monitoring Eastern Hellbender Salamanders (Cryptobranchus alleganienses alleganiensis)
-
Artificial shelters show great promise as novel, non-invasive tools for studying
hellbenders, but their use thus far has faced several challenges. During initial trials in multiple
river networks, artificial shelters routinely became blocked by sediment and dislodged during
high stream discharge events, and were rarely used by hellbenders. We sought to determine
whether these complications could be overcome via alternative shelter design, placement, and
maintenance. Between 2013 and 2018, we deployed 438 artificial shelters of two different
designs across ten stream reaches and three rivers in the upper Tennessee River Basin. We
assessed evidence for several hypotheses, postulating broadly that the availability, stability, and
use of artificial shelters by hellbenders would depend on how shelters were constructed,
deployed, and/or maintained. We found that maintaining shelters at least once every 40 days
limited sediment blockage, and building ~ 40 kg shelters with 3-4 cm thick walls and recessed
lids improved their stability during high discharge events. Additionally, we found that
hellbenders most frequently occupied and nested in artificial shelters when they were deployed
in deeper (~50+ cm) portions of reaches with high adult hellbender densities. Our results suggest
that artificial shelters can serve as effective tools for studying hellbenders when designed,
deployed, and maintained with these advancements, but also highlight some limitations of their
use.

Interactive Conservation Planning for the Appalachian LCC
-
The Appalachian LCC is currently engaged in an effort to develop a draft regional conservation plan for the Cooperative using an interactive and iterative spatial prioritization framework. Using available data and modeling approaches that are well supported in the literature, researchers from Clemson University are developing conservation planning models that include site selection, ecological threat assessments, and broad ranging habitat and ecological connectivity analyses.

Interpretive Text and Graphics for AppLCC Web Portal (conservation planning tools)
-
We have provided some interpretation material and text for conservation planning tools. These programs have been grouped into broad, sometime overlapping purposes. These brief descriptions of the various conservation planning tools can be put up on the AppLCC web portal, for users to get an idea about the tools available and what purposes they could serve. We have alo provided other links, where users can get detailed information about the tool.
