After an absence of more than a decade, a trickle of salmon are finally finding their way back to Sonoma County streams, thanks to private landowners and a coalition of conservationists.
Roughly 22 million years ago, the fish we know as salmon evolved the complicated biology they needed to commute between inland freshwater streams and the open salty ocean. Thus began one of the most remarkable life cycle journeys known on the planet.
Two million years ago, on the ancient California coastline, the salmon would have found a perfect cold and clear waterway emptying into the Pacific near the mouth of today’s Russian River. Running a hundred miles back among high ridges and dense redwood forest, its widely branching network of creeks and tributaries made ideal habitat for the spawning fish and its young.
And that paleo-Russian River has been the salmon’s home ever since.
So it came as a shock in 2001 when naturalists, fishermen and the community discovered that the number of coho salmon counted returning to the Russian River, once totaling 100,000, had dwindled to only 5.
It was found that throughout the watershed, the populations had crashed, and the salmon were disappearing, stream by stream. By 2004, only 3 of 39 tributaries and creeks in the entire watershed held any coho at all.
This past December, in a quiet event out of public view, red-flushed mature coho salmon were once again found spawning in the tree-shaded upper reaches of Mill Creek west of Healdsburg, where they had been virtually absent for decades.
That small, exciting homecoming was no accident. It came after more than 10 years of study and planning, captive breeding and painstaking stream rehabilitation by a smorgasbord of local, state, and federal agencies, private groups, academic institutions, community coalitions and concerned individuals.
And the vital key and the unsung heroes of the salmon rescue, according to those involved, are some of the private landowners whose property surrounds Mill Creek. In a scene that’s playing out along hundreds of miles of streams and creeks across Sonoma County, individual landowners are proving to be the crucial link in bringing the salmon home again.
Tracking the salmon
Everyone involved with salmon rescue in Sonoma County knows Mariska Obedzinski, because it’s her job to count the salmon. A fisheries biologist, Obedzinski is the coho monitoring coordinator for UC Sea Grant. Counting, for Obedzinski and team members Nick Bauer and Zac Reinstein, involves daily checks of underwater traps during the spring, snorkeling through chains of creekbed pools during the summer, and monitoring remote sensors to spot salmon carrying tiny implanted tracking devices.
Before the coho can be upgraded from the red-line federal “endangered” classification, Obedzinski must find 10,100 salmon in the watershed for three consecutive years. This past January, the estimate was 456. That makes every single salmon spawning again in prime habitat like Mill Creek vitally important.
Challenges for the coho
Mill Creek collects water from mountains in one of the wettest spots in Sonoma County, near Venado. Then it burbles and winds for 15 miles through wooded mountain canyons and second growth redwoods, before entering Dry Creek about a mile from the Russian River, and 35 miles from the sea.
4 tips for making the most of your CSA box
You’ve signed up for a CSA, and now it’s time to bring it home. Here are some tips on getting the most out of it.
Get a head start: As soon as you can, process the fresh vegetables so they are ready to eat or cook. Take the tops off beets and store them separately. Remove the tops from carrots, and chop the carrots into sticks. Wash your salad greens and put them in a Tupperware container lined with towels. Rib and chop kale, make a salsa out of your tomatoes, turn the basil into pesto. Freeze your berries.
Juicing for health: If you want to eat your veggies raw, consider buying a $25 juicer so you can energize with a fresh beet and carrot juice.
Clean house: The night before you pick up a new box, go through your crisper drawers and make a soup out of the vegetables remaining from last week. That way you avoid “food guilt” for wasting food, the No. 1 reason people leave a CSA,
Make a vacation plan: If you’re on vacation and your farm does not put your box on hold, share it with a neighbor or donate it to a needy family.
