Scenarios of future land use change around United States’ protected areas
-
Land use change around protected areas can diminish their conservation value, making it important to
predict future land use changes nearby. Our goal was to evaluate future land use changes around protected
areas of different types in the United States under different socioeconomic scenarios. We analyzed
econometric-based projections of future land use change to capture changes around 1260 protected
areas, including National Forests, Parks, Refuges, and Wilderness Areas, from 2001 to 2051, under different
land use policies and crop prices. Our results showed that urban expansion around protected areas
will continue to be a major threat, and expand by 67% under business-as-usual conditions.
Concomitantly, a substantial number of protected areas will lose natural vegetation in their surroundings.
National land-use policies or changes in crop prices are not likely to affect the overall pattern of land use,
but can have effects in certain regions. Discouraging urbanization through zoning, for example, can
reduce future urban pressures around National Forests and Refuges in the East, while the implementation
of an afforestation policy can increase the amount of natural vegetation around some Refuges throughout
the U.S. On the other hand, increases in crop prices can increase crop/pasture cover around some protected
areas, and limit the potential recovery of natural vegetation. Overall, our results highlight that future
land-use change around protected areas is likely to be substantial but variable among regions and
protected area types. Safeguarding the conservation value of protected areas may require serious consideration of threats and opportunities arising from future land use.

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.

Southeast Aquatic Barrier Prioritization Tool
-
The Southeast Aquatic Barrier Prioritization Tool aims to build aquatic connectivity in rivers and streams. The Tool provides inventory data on aquatic barriers (like dams and road-related culverts) and helps practitioners to describe, understand, and prioritize these barriers for removal, restoration, and mitigation.
Aquatic connectivity in rivers and streams is essential for fish and other aquatic organisms.
The Southeast Aquatic Resources Partnership (SARP) developed the tool with support from partners and funders.

The Stream Continuity Portal
-
This aquatic connectivity portal is a one-stop shop for tools and regional collaboratives focused on aquatic organism passage (“fish passage”) and fragmentation of river and stream ecosystems. It is a starting place for stakeholders, users, and tool developers looking to keep track of the latest initiatives and better identify opportunities for collaboration and action. This portal is maintained by the North Atlantic Aquatic Connectivity Collaborative (NAACC). More coming soon!

Using a structured decision making process for strategic conservation of imperiled aquatic species in the Upper Tennessee River Basin
-
Development of strategic conservation of imperiled species faces several large challenges, including uncertainty in species response to management actions, budgetary constraints that limit options, and issues with scaling expected conservation benefits from local to landscape levels and from single to multiple species. We used a structured decision making process and a multi-scale approach to identify a cost-effective conservation strategy for the imperiled aquatic species in the Upper Tennessee River Basin (UTRB), which face a variety of threats. The UTRB, which encompasses a landscape of 22,360 square miles primarily in Virginia, North Carolina, and Tennessee, harbors one of the most globally diverse assemblages of freshwater fishes and mussels occurring at temperate latitudes. In developing the strategy, we sought to identify which management actions to emphasize to best achieve recovery of imperiled aquatic species, given costs and uncertainty in management effectiveness. The strategy was developed for conservation implementation over a 20-year period, with periodic review and revision. In this presentation, we describe the ecological significance of the UTRB, the planning process, and the resulting strategy. A strategic emphasis on population management emerged as the optimal approach for achieving conservation of imperiled aquatic species in the UTRB, which aligns well with the goals of existing plans for conserving and recovering imperiled fishes and mussels in the UTRB. The structured planning process and resulting conservation strategy dovetail with the landscape approach to conservation embodied in the USFWS’s strategic habitat conservation approach and network of Landscape Conservation Cooperatives.
