Secretary Jewell Announces New Wildlife and Climate Studies at the Northeast Climate Science Center
-
Secretary of the Interior Sally Jewell announced recently that Interior’s Northeast Climate Science Center (NE CSC) is awarding nearly $700,000 to universities and other partners for research to guide managers of parks, refuges and other cultural and natural resources in planning how to help species and ecosystems adapt to climate change.

Seeing the landscape for the trees: Metrics to guide riparian shade management in river catchments
-
Rising water temperature (Tw) due to anthropogenic climate change may have serious conse- quences for river ecosystems. Conservation and/or expansion of riparian shade could counter warming and buy time for ecosystems to adapt. However, sensitivity of river reaches to direct solar radiation is highly het- erogeneous in space and time, so benefits of shading are also expected to be site specific. We use a network of high-resolution temperature measurements from two upland rivers in the UK, in conjunction with topo- graphic shade modeling, to assess the relative significance of landscape and riparian shade to the thermal behavior of river reaches. Trees occupy 7% of the study catchments (comparable with the UK national aver- age) yet shade covers 52% of the area and is concentrated along river corridors. Riparian shade is most ben- eficial for managing Tw at distances 5–20 km downstream from the source of the rivers where discharge is modest, flow is dominated by near-surface hydrological pathways, there is a wide floodplain with little land- scape shade, and where cumulative solar exposure times are sufficient to affect Tw. For the rivers studied, we find that approximately 0.5 km of complete shade is necessary to off-set Tw by 18C during July (the month with peak Tw) at a headwater site; whereas 1.1 km of shade is required 25 km downstream. Further research is needed to assess the integrated effect of future changes in air temperature, sunshine duration, direct solar radiation, and downward diffuse radiation on Tw to help tree planting schemes achieve

Significant anthropogenic-induced changes of climate classes since 1950
-
Anthropogenic forcings have contributed to global and regional warming in the last few decades and likely affected terrestrial precipitation. Here we examine changes in major Köppen climate classes from gridded observed data and their uncertainties due to internal climate variability using control simulations from Coupled Model Intercomparison Project 5 (CMIP5). About 5.7% of the global total land area has shifted toward warmer and drier climate types from 1950–2010, and significant changes include expansion of arid and high-latitude continental climate zones, shrinkage in polar and midlatitude continental climates, poleward shifts in temperate, continental and polar climates, and increasing average elevation of tropical and polar climates. Using CMIP5 multi-model averaged historical simulations forced by observed anthropogenic and natural, or natural only, forcing components, we find that these changes of climate types since 1950 cannot be explained as natural variations but are driven by anthropogenic factors.

Sour Streams in Appalachia: Mapping Nature’s Buffer Against Sulfur Deposition
-
Sulfur emissions are regulated by the Environmental Protection Agency, but sulfuric acid that has
leached into soil and streams can linger in the environment and harm vegetation and aquatic life. Some
watersheds are better able to buffer streams against acidification than others; scientists learned why in
southern Appalachia.

South Atlantic LCC
-
The South Atlantic Landscape Conservation Cooperative (SALCC) is part of a national network of Landscape Conservation Cooperatives (LCCs). The partnership will consider landscape-scale stressors, including climate change, habitat fragmentation, invasive species, and water scarcity as it attempts to provide a vision for a landscape capable of sustaining healthy populations of fish, wildlife, plants and cultural resources. The SALCC crosses six states, from southern Virginia to northern Florida.

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.
