In The Nature Conservancy’s California Chapter, Sasha focuses on interdisciplinary research and conservation strategies for rangelands and irrigated agriculture in California. She has 20 years of experience in natural resources management, research, planning, and policy, primarily in California, and has worked in the public and private sectors.

Sasha received an undergraduate degree from Yale College, and an M.S. and Ph.D. from the University of California, Berkeley in the Department of Environmental Science, Policy, and Management, where she studied the effects of livestock grazing and management on vegetation and birds in California grasslands. Sasha also has co-founded two environmental non-profits, and serves on the board of the Golden Hour Restoration Institute.

Organic amendment additions to rangelands: A meta‐analysis of multiple ecosystem outcomes

Kelly Gravuer, Sasha Gennet, Heather L. Throop

Interest in land application of organic amendments—such as biosolids, composts, and manures—is growing among landowners, managers, and climate policy leaders due to their potential to increase soil carbon and help mitigate climate change, as well as to support soil health and regenerative agriculture. While organic…

Inconsistent food safety pressures complicate environmental conservation for California produce growers

Patrick Baur, Laura Driscoll, Sasha Gennet, Daniel Karp

Since a deadly outbreak of pathogenic E. coli in California spinach in 2006, produce growers have been pressured to implement on-farm practices, such as native vegetation removal, in the name of food safety. These practices are damaging to the environment and may conflict with existing laws.…

Agricultural practices for food safety threaten pest control services for fresh produce

Daniel S. Karp, Rebekah Moses, Sasha Gennet, Matthew S. Jones, Shimat Joseph, Leithen K. M'Gonigle, Lauren C. Ponisio, William E. Snyder, Claire Kremen

Food safety concerns have led to pressure on farmers to simplify their farms and landscapes, rather than diversify them. This study demonstrates that two practices – elimination of manure-based composts and removal of non-crop vegetation (i.e. habitat) – are likely having negative impacts on arthropod biodiversity,…

The Unintended Ecological and Social Impacts of Food Safety Regulations in California's Central Coast Region

Daniel S. Karp, Patrick Baur, Edward R. Atwill, Kathryn De Master, Sasha Gennet, Alastair Iles, Joanna L. Nelson, Amber R. Sciligo, Claire Kremen

In 2006, an E. coli outbreak linked to spinach grown in California’s Central Coast region catalyzed reforms in vegetable production. Without evidence, wildlife was targeted as a disease vector and, under industry and governmnet pressure, growers fenced fields, applied wildlife traps and poison, and removed…

Comanaging fresh produce for nature conservation and food safety

Daniel S. Karp, Sasha Gennet , Christopher Kilonzo, Melissa Partyka, Nicolas Chaumont, Edward R. Atwill, Claire Kremen

In 2006, a high profile outbreak of E. coli in spinach was traced to California’s Central Coast. After that outbreak, produce growers were pressured to minimize potential presence of wild animals by removing surrounding natural vegetation that provides habitat, among other practices. This study shows…

Demography linked to climate change projections in an ecoregional case study

B. C. Mclaughlin, C. N. Morozumi, J. MacKenzie, A. Cole, S. Gennet

Anticipating how species will move as the climate changes is a fundamental concern in 21st century conservation. This study modeled potential responses of blue oak (Quercus douglasii), an endemic, flagship species in California, to future climate and then validated the results in the field. This suggests…

Farm practices for food safety: an emerging threat to floodplain and riparian ecosystem

Gennet, S., J. Howard, J. Langholz, K. Andrews, M.D. Reynolds, S.A. Morrison

This paper discusses the 2006 outbreak of toxic foodborne E. coli and its impact on wildlife. The authors explain how farming practices for food safety that target wildlife can damage ecosystems but may not actually improve the safety of the food supply and how high…

Planning for Adaptation to Climate Change: Methods and Lessons Learned from Mt. Hamilton, California

Kirk Klausmeyer, Dan Olstein, Terri Schulz, Robin Cox, Sasha Gennet, Jason MacKenzie

While the literature and guidance on traditional conservation planning methods is extensive, there are few case studies on methods for incorporating climate change into conservation planning efforts. This report outlines the methods the Conservancy used to develop strategies to help species adapt in the Mount…
