Rio Grande National Forest Adaptation Workshop
-
There is an increasing need to consider the anticipated effects of climate change on ecosystems and identify management actions that respond to these changes. This workshop will support participants from the Rio Grande National Forest in determining which climate impacts are of greatest concern to them, and identify management opportunities for adapting to change. The Adaptation Workbook provides a structured process for integrating climate change considerations into management planning and activities.

Scientists Locate Natural “Strongholds” across Southeast US that Could Protect Nature in the Face of Climate Change
-
A new study by The Nature Conservancy has identified a series of natural “strongholds” across the Southeastern United States that are predicted to withstand the growing impacts of climate change and help ensure nature’s survival.

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

Solar energy development impacts on land cover change and protected areas
-
Decisions determining the use of land for energy are of exigent concern as land scarcity, the need for ecosystem services, and demands for energy generation have concomitantly increased globally. Utility-scale solar energy (USSE) [i.e., ≥1 megawatt (MW)] development requires large quantities of space and land; however, studies quantifying the effect of USSE on land cover change and protected areas are limited. We assessed siting impacts of >160 USSE installations by technology type [photovoltaic (PV) vs. concentrating solar power (CSP)], area (in square kilometers), and capacity (in MW) within the global solar hot spot of the state of California (United States). Additionally, we used the Carnegie Energy and Environmental Compatibility model, a multiple criteria model, to quantify each installation according to environmental and technical compatibility. Last, we evaluated installations according to their proximity to protected areas, including inventoried roadless areas, endangered and threatened species habitat, and federally protected areas. We found the plurality of USSE (6,995 MW) in California is sited in shrublands and scrublands, comprising 375 km2 of land cover change. Twenty-eight percent of USSE installations are located in croplands and pastures, comprising 155 km2 of change. Less than 15% of USSE installations are sited in “Compatible” areas. The majority of “Incompatible” USSE power plants are sited far from existing transmission infrastructure, and all USSE installations average at most 7 and 5 km from protected areas, for PV and CSP, respectively. Where energy, food, and conservation goals intersect, environmental compatibility can be achieved when resource opportunities, constraints, and trade-offs are integrated into siting decisions.

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.
