Plant & Habitat Restoration
Since 1993, we’ve worked side by side with landowners and volunteers on projects that restore, protect, and improve our natural heritage. We have developed a deep understanding of the Valley and its ecology, and its residents and their concerns. With expertise in native plants and animals and invasive species, and with experience, ready permits, and an ability to secure grants, SEC staff help make watershed projects less costly and move faster for landowners and land managers.

Nathanson Creek Preserve
Working with community experts and students, SEC secured over $2 million in grant funding to design and build this ¾ mile preserve. Nathanson Creek Preserve successfully meets multiple goals: it provides educational opportunities for three nearby schools, serves to assist with stormwater management, and it provides the community with recreational space, while benefiting fish and wildlife through enhanced stream habitat. It is widely used by residents and visitors.
Fryer Creek Restoration
Partnering with the City of Sonoma and the Sonoma County Water Agency, Sonoma Ecology Center has improved this 1960s-era flood control channel so it functions like a natural stream. Fryer Creek still maintains flood control, but it now also has native plants that enhance and restore the stream habitat, improved water quality for fish and wildlife, and a scenic walking path for people.
Sonoma Creek Habitat Restoration
Sonoma Creek is one of the most important streams in the Bay Area because of its native fish and wildlife. SEC staff, partners, and creekside landowners have helped to restore Sonoma Creek over the past 20 years by: removing barriers to native fish migration, improving fish habitat, keeping stream banks and beds from washing away, slowing and filtering stormwater, removing weeds, and planting native plants.
Native Plant Propagation
Native plants are key to a healthy ecosystem: they support and sustain native fish and wildlife, stabilize creek banks, and—because they are adapted to native soils—they have more efficient water uptake and can improve water infiltration for groundwater. Over the last five years, SEC has grown and planted over 25,000 native plants. Read more about native plants and our Native Plant Nursery.
Invasive Weed Removal
After human development, invasive species are the second greatest cause of habitat loss in the world. In addition to displacing native plants and animals, invasives can increase fire risk and harbor pests. SEC staff created the model for eradication of Arundo (a highly invasive weed in Western streams) in California. Read more about invasives and SEC’s work to eliminate them locally.
Mark Newhouser, Restoration Program Manager
BA Environmental Studies, Sonoma State University
Mark has over 20 years of experience in restoration project management, including planning, design, and construction. His completed projects include fish and wildlife habitat enhancement, stormwater management, river parkway development, and preserve management. He is also a natural resource workshop and field school instructor, specializing in invasive weed species ecology and control methodology. For nine years he coordinated Arundo donax eradication efforts throughout the Bay Delta watershed and is a Licensed Contractor and a Licensed Pesticide Applicator.
Jemma Williams, Restoration Specialist
BA in Geography and Mapping Science with a minor in Natural Resources, Humboldt State University
Jemma has 6 years experience in Natural Resource management and served two terms of the AmeriCorps program in watershed restoration. Since then she has held various positions in Natural Resource management and riparian zone restoration. She has performed both plant and animal species surveys, designed and implemented habitat restoration projects, and worked in many of the various ecosystems of the West coast. She is interested in human environment interactions, sustainable land management, and ecological enhancement techniques.
Michael Ziglar, Horticulture Specialist
BS in Conservation and Resource Studies, UC Berkeley
Michael also has a minor in Forestry and worked at Richardson Bay Audubon Center where he helped enhance and develop the nursery. Michael spent some time as a farm intern in Hawaii and was a scientific aide with CA Department of Fish and Wildlife.
