Planning for Wildlife Movement Across San Diego’s SR-67

In 2014, IEMM began investigating the dangers posed to wildlife along State Route 67 in order to inform rehabilitation planning for the highway.

We studied SR-67’s existing culvert structures, investigated roadkill, and analyzed bobcat and ringtail movement data to help the California Department of Transportation plan for making SR-67 safer for wildlife. Our findings were used to inform initial safety measures on the highway.

Working closely with a range of stakeholders, IEMM also completed a comprehensive connectivity analysis using existing data on a suite of local species ranging from pumas to wrentits in an expanded area beyond the highway.

Our connectivity modeling has informed prioritization of conservation actions, including a wildlife infrastructure plan for the highway. We also developed a decision support tool based on our data products to guide strategic conservation actions such as land acquisitions, land restorations, and other habitat enhancement activities.


More Ecological Management and Conservation Projects

California least tern monitoring
Led by IEMM in 2014, this project is facilitating the implementation of a scientifically robust, statewide monitoring and management program for California least terns. Species recovery objectives and current understanding of California least tern ecology guide IEMM’s research methods and goals.
Mule deer conservation
This project aims to improve upon past deer population surveys in San Diego County. Our work involves informing more effective management decisions, as well as further investigating and better addressing population health, landscape fragmentation, and other factors that may impact the deer.
Peninsular sheep population monitoring
Working in partnership with the California Department of Fish and Wildlife, SDSU researchers are determining demographic parameters that drive Peninsular bighorn sheep population growth. Our up-to-date population models inform targeted management options in response to predicted sources of population decline.
Feral pig monitoring
IEMM’s feral pig monitoring program informs the strategy and actions of a county-wide cooperative wild pig eradication effort. Since 2014, SDSU scientists have been part of the Feral Pig Working Group, which includes 11 state, local, federal, and Tribal government agencies.
