Research Program:

Dr. Steven Ostoja is the director of the USDA California Climate Hub at Agricultural Research Service currently working on ecosystem management and rangeland restoration. The California Hub works at the science-practitioner interface alongside researchers and managers to develop and deliver science-based, region-specific information and products that supports climate-informed decision-making and adaptive capacity.  

The USDA California Climate Hub seeks to listen to the practical needs of those dealing with climate adaptation on the ground – resource managers, farmers, ranchers, forest owners, tribal authorities, and their representatives and advocates. To meet our users’ informational needs, we will draw upon our broad base of science and policy knowledge and will reach out to subject-specific experts.

Biography:

Steve is a native Californian from nearby Sacramento who earned his BS in ecology and MS in biological sciences from Cal Poly, San Luis Obispo. Steve went on to earn his PhD in ecology and conservation biology from Utah State University where his research focused on the effects of invasive species on wildlife communities and resource-consumer interactions in an applied rangeland restoration context. Before joining the Hub, Steve worked for the US Forest Service where he was head of the ecosystem management department on the Sierra National Forest. Prior to that, he worked as a supervisory ecologist for the US Geological Survey in the Yosemite office where he managed a research program that focused on invasive species management, restoration ecology, conservation biology and the effects of various stressors, including climate change, to plant and animal populations and communities. Steve joined the USDA California Climate Hub in September 2016.
