New research relevant to conservation in western North America

The Conservation Science Blog is intended to bring new and relevant research to the attention of conservation scientists, and facilitate discussion on how to apply this science to further conservation goals in western North America.

New version of Connectivity Analysis Toolkit (1.3.1) released

The Connectivity Analysis Toolkit is a software interface that provides conservation planners with tools for both linkage mapping and landscape-level ‘centrality’ analysis.

We have just released Version 1.3.1 with the following changes:
Updated LEMON to version 1.3.
Turned off arc mixing in network flow functions to resolve potential division by zero error.
Updated NetworkX to version 1.8.1.
Updated Hexsim-based functions to Hexsim version 2.5.3.

The free software can be downloaded here.

Society for Conservation Biology meeting hosts symposium on defining the meaning of endangered species recovery

On July 24, a symposium at the ICCB conference in Baltimore, Maryland brought together a multi-disciplinary group of biologists and policy experts from the US and Canada to address policy questions surrounding the definition of recovery, as well as the related issue of how planners can efficiently and transparently develop recovery criteria that guide recovery efforts.The US Endangered Species Act and Canada’s Species at Risk Act (SARA) are among the world’s most important biodiversity-related statutes. The Canadian federal government has suggested that SARA needs to be streamlined, in part by substituting ecosystem conservation for time-consuming recovery plans developed for individual species. In the US, recent reviews have proposed that, given the number of taxa which may require species-specific conservation measures in perpetuity, policymakers need to shift emphasis from long-term federal management of listed species to more rapid delisting that allows management by state and private entities. In contrast, others see such calls for more streamlined planning and management as undermining conservation of vulnerable taxa. In essence, this debate hinges on unresolved questions concerning how the public interprets the meaning of recovery and what cost it is willing to bear to achieve it. For some, recovery may imply self-sustaining populations that can play their historic role in ecosystems, whereas others see recovery of a small intensively-managed population as sufficient. The talks can be downloaded from the links given below.
