Presentation of Review of Species and Habitat Selection for Climate Change Vulnerability Assessment Meeting on 1/14/14
-
On January 14, Lesley Sneddon of NatureServe presented this webinar to interested conservation and cooperative partners of the Appalachian LCC to present the process for the selection of the 50-75 species and 3-5 habitats proposed for assessment of climate change vulnerability. The selections were informed by the wealth of assessments already completed in all or part of the LCC region to date. The meeting generated good discussion on the process, species, habitats, and possible avenues for future research.

Protected areas in Borneo may fail to conserve tropical forest biodiversity under climate change
-
Protected areas (PAs) are key for conserving rainforest species, but many PAs are becoming increasingly
isolated within agricultural landscapes, which may have detrimental consequences for the forest biota
they contain. We examined the vulnerability of PA networks to climate change by examining connectivity
of PAs along elevation gradients. We used the PA network on Borneo as a model system, and examined
changes in the spatial distribution of climate conditions in future. A large proportion of PAs will not
contain analogous climates in future (based on temperature projections for 2061–2080), potentially
requiring organisms to move to cooler PAs at higher elevation, if they are to track climate changes. For
the highest warming scenario (RCP8.5), few (11–12.5%; 27–30/240) PAs were sufficiently topographically
diverse for analogous climate conditions (present-day equivalent or cooler) to remain in situ. For the
remaining 87.5–89% (210–213/240) of PAs, which were often situated at low elevation, analogous climate
will only be available in higher elevation PAs. However, over half (60–82%) of all PAs on Borneo are too
isolated for poor dispersers (<1 km per generation) to reach cooler PAs, because there is a lack of connecting
forest habitat. Even under the lowest warming scenario (RCP2.6), analogous climate conditions will
disappear from 61% (146/240) of PAs, and a large proportion of these are too isolated for poor dispersers
to reach cooler PAs. Our results suggest that low elevation PAs are particularly vulnerable to climate
change, and management to improve linkage of PAs along elevation gradients should be a conservation
priority

Service Report: Nation’s Rivers Flow toward Better Habitat, Economies and Public Safety
-
More than 200 blockages in the nation’s major natural resource “arteries” were removed last year thanks to the U.S. Fish and Wildlife Service’s National Fish Passage Program. Working with numerous partners, the program improves fish passage, local economies and public safety by ridding the nation’s rivers of derelict dams that no longer serve a purpose.

South-Central Interior Small Stream and Riparian Habitat
-
This habitat was assessed in both the Cumberland - Southern Appalachian subregion and the Interior Low Plateau subregion. Results are in the first two tabs of the spreadsheet. A description of the habitat, and a list of associated species, is included in the description tab. The remaining tabs describe the individual factors and their definitions. These results are in the review stage. Please send comments to lesley_sneddon@natureserve.org.

Stream channel geomorphology influences mussel abundance in southern Appalachian streams, U.S.A.
-
We quantified freshwater mussel abundance and species richness and their physical habitat at 24 sites in eight streams in southern Appalachian catchments in 2000 and 2001. In addition, we modelled site-specific hydraulic parameters during summer baseflow and bankfull stages to estimate high- and low-discharge conditions, respectively.
Mussel abundance was related to stream geomorphology, whereas richness was related to stream size. Baseflow habitat parameters explained only minor variation in abundance or richness, and both measures were highly correlated with mean current velocity or stream size. Bankfull shear stress composed a relatively low proportion of overall mussel habitat variability, but it accounted for significant variation in abundance and richness. Mussel abundance was highly variable at sites subject to low-shear stress during spates, whereas abundance always was low at sites subject to high-shear stress. These data suggest that habitat conditions during floods, rather than those at summer baseflow, limit the abundance of mussels in Appalachian streams. These data also suggest that mussel abundance and assemblage structure may be sensitive to any changes in channel geomorphology and hydraulic conditions that might result from land use in the catchment.
