In her role with the Nature Conservancy’s California Chapter, Trish works with government agencies, research institutions, land managers and non-governmental agencies to develop and implement coordinated regional programs for the management and monitoring of plant and animal communities in southern California. She has worked extensively on the implementation of Habitat Conservation Plans/Natural Community Conservation Plans in Orange and San Diego Counties, where much of her work has focused on developing plans and strategies for habitat connectivity, rare plant management and monitoring, habitat restoration, and fire management. She also works to build networks of land managers, scientists, and government agencies to address and collaborate on issues related to conservation and management of imperiled species.
Prior to joining the Conservancy, Trish worked as a restoration ecologist with an environmental consulting firm. Trish is a 6th generation Californian and has been working in conservation in southern California for over 20 years. She holds a B.S. from California Polytechnic State University, San Luis Obispo and an M.L.A. from California Polytechnic State University, Pomona, School of Urban and Regional Planning.

The Nature Conservancy and the California Department of Transportation are planning 3 wildlife crossing infrastructure projects along a 3-mile stretch of Interstate 15 (I-15) in the Santa Ana-Palomar Mountains Linkage in southern California. While wildlife crossings are becoming more common, optimal designs that meet the…

Highways across the greater San Diego region in southern California are major barriers and causes of mortality for mountain lions and are contributing to the species’ genetic restriction and threat of extirpation. Due to their large territories, mountain lions must regularly cross highways in this…

Freeways are barriers to wildlife passage and gene exchange. In Southern California, mountain lion movement has been severely restricted due to this infrastructure. As a result, the mountain lions in the Santa Ana and Santa Monica Mountains have become severely inbred, threatening their long-term health and…

Conservation of wide-ranging species like mountain lions is especially difficult in highly fragmented landscapes, such as coastal southern California. Research into their populations can provide important insights into what is needed to protect them, such as where to prioritize habitat conservation or restoration. This paper…

Coastal southern California has long been the focus of regional conservation planning efforts. Decades ago – and prior to today’s heightened awareness of the magnitude of the likely impacts climate change – reserve designs were established with the intent of protecting the region’s very diverse…
