Kathryn McEachern
Biography
Dr. Kathryn McEachern began her career in the open pit coal mines of Pacific Power and Light in Wyoming and Montana. There she designed long-term vegetation monitoring programs, directed topsoil salvage operations, and designed and tested native plant seed mixes for habitat reclamation. Her interest in ecosystem restoration led her to the University of Wisconsin-Madison, where she participated in the restoration ecology group, and helped design a new Conservation Biology Master’s program. In 1988, she began working with the National Park Service in the Great Lakes region on conservation of coastal ecosystems. She began long-term studies of a threatened dune thistle in one of the habitats she loves best: coastal dunes. Her research interests led her to the California south coast, where she continues to study rare plants and vegetation. Her particular interests are in the study of how the vegetation forms the context for rare plant persistence, as seen through long-term demographic patterns in the rare plants of the California Channel Islands. To look at this question, she is tracking the native and alien plant communities of the islands along with a suite of rare native plants that inhabit these communities. She guides the Prototype Vegetation Monitoring Program at Channel Islands National Park, and assists other agencies with plant community and rare plant monitoring program design.

Science and Products
Drivers of Ecosystem Recovery on Santa Rosa Island
The Channel Islands were used as ranches for almost 150 years. Sheep, cattle, pigs and other livestock grazed on native perennial scrub, leaving behind barren landscapes that could not collect moisture from coastal fog. In time, ranching ended and livestock were removed. WERC’s Dr. Kathryn McEachern is monitoring habitat recovery and testing the efficacy of restoration practices on the islands...
Developing Monitoring Programs for Damaged Ecosystems
California’s Channel Islands are recovering from a long history of ranching. As the island ecosystems respond to the absence of livestock, WERC’s Dr. Kathryn McEachern is working with the National Park Service to test new monitoring programs that could help ecologists and biologists study recovering environments across the West.
Restoring Rare Plants on Public Lands
Ecosystems throughout the U.S. face threats from invasive species and rapid changes to the environment. Dr. Kathryn McEachern is studying the long-term effects of invasive plants and animals, and environmental change on the survival and recovery of rare plants across the 18 California Islands and in the Great Lakes.
Channel Islands Field Station
Eight islands make up the California Islands archipelago in the United States, extending from Point Conception to the U.S. border with Mexico. The archipelago extends even farther south off the coastline of Baja Sur, Mexico, adding another 10 islands to the chain. WERC’s Channel Islands Field Station is the site of key research on endangered plants, invasive species, and conservation projects...
Effects of life history and reproduction on recruitment time lags in reintroductions of rare plants
Reintroductions are important components of conservation and recovery programs for rare plant species, but their long‐term success rates are poorly understood. Previous reviews of plant reintroductions focused on short‐term (e.g., ≤3 years) survival and flowering of founder individuals rather than on benchmarks of intergenerational persistence,...

Informing our successors: What botanical information for Santa Cruz Island will researchers and conservation managers in the century ahead need the most?
Climate changes are predicted to drive changes in plant species composition and vegetation cover around the world. Preserved specimens and other botanical information that we gather today—a period future practitioners may look back on as an early stage of modern anthropogenic climate change—will be of value to conservation managers and...

Quercus tomentella (island oak) is an endemic species that plays a key functional role in Channel Island ecosystems. Growing in groves on highland ridges, Q. tomentella captures fog and increases water inputs, stabilizes soils, and provides habitat for flora and fauna. This cloud forest system has been impacted by a long history of...
Woolsey, Jay; Hanna, Cause; McEachern, A. Kathryn; Anderson, Sean; Hartman, Brett D. Oak habitat recovery on California's largest islands: Scenarios for the role of corvid seed dispersal
Seed dispersal by birds is central to the passive restoration of many tree communities. Reintroduction of extinct seed dispersers can therefore restore degraded forests and woodlands. To test this, we constructed a spatially explicit simulation model, parameterized with field data, to consider the effect of different seed dispersal scenarios on...
Pesendorfer, Mario B.; Baker, Christopher M.; Stringer, Martin; McDonald-Madden, Eve; Bode, Michael; McEachern, A. Kathryn; Morrison, Scott A.; Sillett, T. Scott Population-specific life histories contribute to metapopulation viability
Restoration efforts can be improved by understanding how variations in life-history traits occur within populations of the same species living in different environments. This can be done by first understanding the demographic responses of natural occurring populations. Population viability analysis continues to be useful to species management and...

Channel Islands: Invasive Species
Imagine being a fragile seedling pushing through the earth and reaching for the sun — but constantly being smothered by strange grasses growing faster and taller than you are. That is the plight of the Island Phacelia (Phacelia insularis var. insularis), a tiny flower found only on Santa Rosa and San Miguel Islands, part of the remote and hauntingly gorgeous Channel
..."Fog and Wind" - Cloud Forests of Santa Rosa Island
Fog and wind are ever present on Santa Rosa Island -- one of the Channel Islands offshore of Los Angeles and southern California. Fog condenses on twigs and leaves of island woodland plants, dripping and soaking into the ground. These "cloud forests" harvest the fog and provide critical water for wildlife and the ecosystem.
