Russian River Salmon & Steelhead Monitoring Program biologists visit more than 40 streams where they monitor salmon and steelhead populations. These biologists spend a lot of time in the water looking for fish. Here's how much territory they covered in 2015.
- Number of streams- 42
- Length of stream surveyed- 96.3 miles
- Total stream length covered by crews the entire season: 192.6 miles; the equivalent of walking from Santa Rosa to Lake Tahoe.
2014-15 Spawner Survey Season – counting adult salmon and steelhead and their nests (redds):
- Number of streams- 22
- Length of stream surveyed- 76.4 miles
- Total stream length hiked by crews the entire season: 630 miles; the equivalent of walking from Santa Rosa to Portland, OR.
2015 Wetted Habitat Surveys - documenting low summer stream flow conditions as experienced by juvenile fish rearing in streams. Each site is visited one time for these surveys:
- Number of streams- 32
- Length of stream surveyed- 93.8 miles; the equivalent of a round trip to Santa Rosa to San Francisco.
Total stream length hiked by crews for all surveys in 2015: 916.4 miles which is the equivalent of walking from Santa Rosa, CA to Albuquerque, NM.

On Martin Luther King Jr. Day, members of the greater Santa Rosa community celebrated the National Day of Service at Paulin Creek Open Space Preserve. Over 100 volunteers from 4H, local girl scout troops, Youth Connections, AmeriCorps and local neighbors came together to help preserve a critical riparian corridor within urban Santa Rosa. These engaged community members removed invasive French Broom from the preserve and planted native seed. These efforts will help the vegetation return to its natural state, improving wildlife habitat and stream health.
In conjunction with Sorrel Allen from the Sonoma County Agricultural Preservation and Open Space District (SCAPOSD), this volunteer event was organized by Troy Cameron and Jenna Dohman, AmeriCorps members from the Watershed Stewards Program serving their term at California Sea Grant. The SCAPOSD has ongoing volunteer efforts to protect and enhance the natural resources in this preserve. The Watershed Stewards Program and SCAPOSD would like to thank all the 4H members that participated in this event, helping to protect natural resources in Sonoma County for future generations.
The Sonoma County Agricultural Preservation and Open Space District (SCAPOSD) purchased this land in 2002 when prospective development of two parcels of the land raised public awareness about the property and led to a call for preservation. The Paulin Creek Preserve encompasses 46 acres of land and 9 of those acres are owned by SCAPOSD which are open year-round to the public.
Paulin Creek flows through the middle of this preserve. It flows westward into Piner Creek, then Santa Rosa Creek, the Laguna de Santa Rosa, and finally reaches the Russian River before flowing out into the ocean. The Russian River is a class 1 fisheries stream as it has threatened and endangered salmonid species including Coho, Chinook, and Steelhead. Specifically, Steelhead have been seen in Paulin Creek, so this habitat is very important for the survival of the species in the Russian River system. The Sonoma County Water Agency also owns a portion of this preserve and on their portion, there is a dam with a flood control reservoir. This holds back water to prevent flooding, but outflows are released throughout the year, so downstream of this dam Paulin Creek has water all year, even through the dry season in the summer. Paulin Creek Open Space Preserve also has diverse vegetation. It is home to a number of native plants including mixed grasslands, mixed oak woodlands (bays, coast live oak, Oregon oak, madrone, big leaf maple, buckeye), understory (snowberry, poison oak, native honeysuckle, native blackberry toyon) riparian woodlands and wetlands.
There are also invasive plants present including the French Broom that was removed during this event! While invasive plants can sometimes be pretty, they can severely outcompete native plants. Because they are foreign to the landscape, they may not have any natural predators in the area. Native plants might also not have defenses appropriate for this new plant. An invasive plant might be aggressive enough to completely dominate an area of land, which decreases biodiversity. As the invasive plant takes over, it can change food webs in an ecosystem. An animal used to eating the plant life in one area may not get the necessary nutrients from this new invasive plant, causing these animals to move to a new location. Similarly, new species of animals may come to eat this invasive plant.
Needless to say, this volunteer effort to remove invasive French Broom will greatly benefit the wildlife habitat on the Paulin Creek Preserve. Thanks again to all the volunteers who took time out of their busy schedules to lend a hand in their community!

Troy Cameron grew up in Sonoma County and started his career with the Sonoma Ecology Center followed by work for the Bureau of land Management in Oregon. He studied Environmental Science in New Zealand where he received his undergraduate degree from Massey University. This fall, he returned to Sonoma County as a WSP member to work with the Coho Salmon Monitoring Program.
Jenna Dohman studied at Western Washington University and earned a degree in Environmental Science. As an undergraduate she experimented with algae in a marine chemistry laboratory. After graduating, she completed field work in the Idaho Wilderness and the Mojave Desert before coming to Sonoma County as a WSP member with the Coho Salmon Monitoring Program.
