Baby harbor seals at rest alongside their mothers on the banks of the Russian River estuary mark the arrival of another pupping season and the passage of another year that Elinor Twohy, 94, has kept watch.
Stationed in and around her riverfront cottage on the northernmost reaches of the estuary, Twohy has maintained a record of daily observations on the seal colony for more than a quarter century, taking on the mantle of citizen science long before the phrase was in common use.
Hers is a commitment built on curiosity and scrupulous attention that evolved after she and her late-husband, John, first bought what was then a cozy weekend home at the river’s end 52 years ago, acquiring close-up views of the ever-changing world right outside their doors.
But Twohy’s work also has served to inform a number of scientific studies over time, supplying long-term, standardized data on the seals’ haul-out habits, as well as river conditions and other observations at a level of detail and quality seldom available.
“These sorts of 30- or 40-year data sets don’t exist,” said Bay Area hydrologist Dane Behrens, who used Twohy’s observations and photos as a UC Davis doctoral student in his research on dynamics that shape the river’s tidal lagoon. “For someone to have done this for so long, so diligently… I mean, it was at the point where if she went on vacation, she found someone to do it for her.”
Twohy’s preoccupation with the Jenner seals arose decades ago through her growing interest in coastal wildlife and a burgeoning awareness of the importance of conservation, born in part through her participation in a late 1960s campaign to fend off plans to dredge gravel from the Russian River estuary. Twohy said her initial encounter and friendship with a local environmentalist, the late Virginia Hechtman, helped crystallize her appreciation for the coast and her understanding that “we could lose all the natural wonders here.”
Twohy later helped battle a planned housing division and, with her husband, called for permanent protection of the Jenner Headlands more than three decades before a conservation purchase in 2009 made it so, Jenner Headlands Preserve Manager Brook Edwards said.
In the early 1970s, around the time she and her husband moved full time to Jenner, Twohy began noticing increasing numbers of harbor seals hauling out at the river mouth. They have since become a year-round colony.
