Conservation Strategy for Imperiled Aquatic Species in the UTRB
-
The Strategy provides guidance to Field Offices in reevaluating current ("status quo") conservation approaches in order to deliver the most cost effective approach toward the conservation and management of imperiled freshwater fish and mussel species in the Upper Tennessee River Basin.

Conservation in the face of climate change: The roles of alternative models, monitoring, and adaptation in confronting and reducing uncertainty
-
The broad physical and biological principles behind climate change and its potential large scale ecological impacts on biota are fairly well understood, although likely responses of biotic communities at fine spatio-temporal scales are not, limiting the ability of conservation programs to respond effectively to climate change outside the range of human experience. Much of the climate debate has focused on attempts to resolve key uncertainties in a hypothesis-testing framework. However, conservation decisions cannot await resolution of these scientific issues and instead must proceed in the face of uncertainty. We suggest that conservation should precede in an adaptive management framework, in which decisions are guided by predictions under multiple, plausible hypotheses about climate impacts. Under this plan, monitoring is used to evaluate the response of the system to climate drivers, and management actions (perhaps experimental) are used to confront testable predictions with data, in turn providing feedback for future decision making. We illustrate these principles with the problem of mitigating the effects of climate change on terrestrial bird communities in the southern Appalachian Mountains, USA.

Six Common Mistakes in Conservation Priority Setting
-
A vast number of prioritization schemes have been developed to help conservation navigate tough decisions about the allocation of finite resources. However, the application of quantitative approaches to setting priorities in conservation frequently includes mistakes that can undermine their authors’ intention to be more rigorous and scientific in the way priorities are established and resources allocated. Drawing on well-established principles of decision science, we highlight 6 mistakes commonly associated with setting priorities for conservation: not acknowledging conservation plans are prioritizations; trying to solve an ill- defined problem; not prioritizing actions; arbitrariness; hidden value judgments; and not acknowledging risk of failure. We explain these mistakes and offer a path to help conservation planners avoid making the same mistakes in future prioritizations.

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.
