River Otter (Lontra Canadensis) Monitoring Report 2019 Marin County, California
PO Box 103 Web: riverotterecology.org Forest Knolls, CA 94933 Facebook.com/BayAreaOtters 415.342.7956 Instagram: riverotterecology River Otter (Lontra canadensis) Monitoring Report 2019 Marin County, California The River Otter Ecology Project PO Box 103, Forest Knolls, CA 94933 By Megan Isadore and Terence Carroll February 21, 2020 Daniel Dietrich The River Otter Ecology Project 1 February 21, 2020 Background While historical records on river otters in the San Francisco Bay Area are sparse, existing information indicates that river otters had been extirpated from much, if not all, of Marin County by the 1930’s when both Grinnell and trapping records indicate no coastal river otters in Marin and southward. Beginning in 1989, river otters were noticed in coastal Marin County, particularly in Rodeo Lagoon, Walker Creek, and Lagunitas Creek. As apex predators using variety of terrestrial and aquatic habitat types, river otters are sentinel indicators of watershed function and health (Larivière and Walton 1998). They predate a wide variety of native and non-native species in freshwater and marine environments (Penland and Black 2009, Garwood and others 2013). They are susceptible to parasites such as Cryptosporidium and Giardia spp. (Gaydos and others 2007), and Vibrio spp. (Bouley and others 2015), and they may bioaccumulate environmental contaminants such as mercury, metals, organochlorines, and hydrocarbons (Francis and others 1994, Halbrook and others 1996, Bowyer and others 2003). Furthermore, understanding river otter ecology and population status is a critical element of ecosystem management (Bowen 1997, Kruuk 2006, Ben-David and Golden 2009). River otters transport aquatic nutrients to land (Ben-David and others 2004); transmit trophic effects (Crait and Ben-David 2007); and affect the composition and abundance of prey species via trophic subsidy (Garwood and others 2013). -

This radio program was originally broadcast on KWMR in Point Reyes Station, California. Thanks for listening! (Music) Jennifer Stock: Hi there, everyone. Good afternoon. You're listening to Ocean Currents, a show where we talk about the blue part of our planet, the mighty ocean. My name is Jennifer Stock and I bring this show to KWMR from the Cordell Bank National Marine Sanctuary, which is one of the most unique, vibrant marine ecosystems off the coast here of Point Reyes and part of a national system of special marine protected areas off the coast here. On Ocean Currents, we focus on what's happening out there in what covers three-quarters of the planet. So, there's a lot of territory to cover on this show. We talk about discoveries, research, ocean policy, and ways for us land-based folks to get involved and learn more. This program runs the first Monday of every month if you'd like to tune in regularly and it's part of the West Marin Matters series where every Monday at 1 on KWMR, you can tune in to listen in about a local environmental or economic topic. This is a special month in June. We celebrate World Oceans Day. It's actually tomorrow and June 11th marks Jacques Cousteau’s 100th birthday. -

Climate Change Report for Gulf of the Farallones and Cordell
Chapter 6 Responses in Marine Habitats Sea Level Rise: Intertidal organisms will respond to sea level rise by shifting their distributions to keep pace with rising sea level. It has been suggested that all but the slowest growing organisms will be able to keep pace with rising sea level (Harley et al. 2006) but few studies have thoroughly examined this phenomenon. As in soft sediment systems, the ability of intertidal organisms to migrate will depend on available upland habitat. If these communities are adjacent to steep coastal bluffs it is unclear if they will be able to colonize this habitat. Further, increased erosion and sedimentation may impede their ability to move. Waves: Greater wave activity (see 3.3.2 Waves) suggests that intertidal and subtidal organisms may experience greater physical forces. A number of studies indicate that the strength of organisms does not always scale with their size (Denny et al. 1985; Carrington 1990; Gaylord et al. 1994; Denny and Kitzes 2005; Gaylord et al. 2008), which can lead to selective removal of larger organisms, influencing size structure and species interactions that depend on size. However, the relationship between offshore significant wave height and hydrodynamic force is not simple. Although local wave height inside the surf zone is a good predictor of wave velocity and force (Gaylord 1999, 2000), the relationship between offshore Hs and intertidal force cannot be expressed via a simple linear relationship (Helmuth and Denny 2003). In many cases (89% of sites examined), elevated offshore wave activity increased force up to a point (Hs > 2-2.5 m), after which force did not increase with wave height. -
Environmental History and Oysters at Point Reyes National Seashore
Restoring the Past: Environmental History and Oysters at Point Reyes National Seashore Timothy Babalis Since its inception more than 40 years ago, environmental history has matured into a respected, if somewhat nebulous, discipline in academic circles but has so far received less attention within public land management agencies such as the National Park Service.1 This is unfortunate, because environmental history can provide information of great practical interest to resource managers as well as offering a valuable perspective on management prac- tices. The singular characteristic which distinguishes environmental history from other his- torical methodologies is the acknowledgement that history happens in places. Like geogra- phers, whose field is closely related, environmental historians consider the spatial dimension of history to be just as important as its temporal. As a result, the physical environment is one of environmental history’s principal subjects, along with the usual human actors, political events, and cultural expressions of traditional history. But environmental history also acknowledges the active capacity of the environment to influence and form human history,as well as being the place where that history unfolds. Environmental historians study the recip- rocal relationship between human societies and the physical environments they inhabit. As one prominent environmental historian has written, “When I use the term ‘environmental history,’I mean specifically the history of the consequences of human actions on the environ- ment and the reciprocal consequences of an altered nature for human society.”2 While most environmental historians agree on this basic formula, the field quickly diverges in a bewildering number of directions and becomes increasingly difficult to catego- rize or define. -
Tomales Bay Harbor Seals: a Colony at Risk, 1992
THIRD BIENNIAL STATE OF TOMALES BAY CONFERENCE October 24, 1992 Tomales Bay Harbor Seals: A Colony at Risk? Sarah G. Allen, Point Reyes Bird Observatory 4990 Shoreline Hwy, Stinson Beach Ca 94970 Mary Ellen King, Audubon Canyon Ranch 4900 Shoreline Hwy, Stinson Beach Ca 94970 INTRODUCTION Conservation, management, and protection of harbor seats come under the purview of the Marine Mammal Protection Act (MMPA) of 1972 (Public Law 92-522). A primary directive of the MMPA is to protect marine mammal stocks from declining below their optimum sustainable population. To fulfill this directive in California, the California Department of Fish and Game (CDFG), in cooperation with the National Marine Fisheries Service (NMFS), has been conducting annual, state-wide, aerial surveys of harbor seals to assess the status of the population. Harbor seal colonies along the Point Reyes coastline represent about 20% of the estimated breeding population of the state of California, and consequently, have received attention from CDFG and NMFS. In cooperation with these agencies and supported by the Point Reyes National Seashore and the Gulf of the Farallones National Marine Sanctuary, S. Allen has been monitoring harbor seals in Point Reyes since 1982. Audubon Canyon Ranch has supported surveys in Tomales Bay conducted by M. King and volunteers since 1991. Tomales Bay is one of several locations along the Point Reyes Peninsula where harbor seals (Phoca vitulina richardsi) congregate onshore. Resting areas or "haul-out" sites in Point Reyes are found in remote areas on tidal sand bars, sandy pocket beaches, and offshore tidal ledges or islands (Figure 1). -

She was my second celebrity encounter since moving back to Northern California last year, the first being a certain celebrity chef cutting me off on Highway 12. I later learned that Ms. Hedren’s appearance is an annual tradition, and that some of the money she makes from it goes to support her extensive charity work. Though I’ve never seen the film in its entirety, I learned the story through multiple trips to the restaurant and the Saint Teresa of Avila Church in Bodega. Even I, who spent the majority of my life in Middle Tennessee, feel local pride knowing these beautiful places are immortalized in such a loved and influential film. -

Welcome to Our Home! Please Take a Few Minutes to Look Through This
Welcome to our home! Please take a few minutes to look through this binder, as it contains lots of useful information about the house and grounds. Over the past six years, our wonderful community of friends, neighbors and many craftspeople have helped us revitalize the ranch, including rebuilding our beautiful, memory-filled 150-year-old hay barn - please feel free to go in and check it out (there’s some cool old farm photos in there, too)! While you’re here, be sure to enjoy the star-filled skies, magnificent sunsets across the bay and also learn about a handful of activists who saved West Marin from development, captured in the documentary, “Rebels with a Cause” (there’s a DVD in the TV room). Whether you’ve come to celebrate, retreat or escape, we hope you have a wonderful stay, and please don’t hesitate to let us know if there’s anything you need. Michael, Vivien & Miriam Straus (siblings) October, 2020 The Important Stuff Parking - Please keep the driveways clear (and don’t block the gates to the fields), super important because farm vehicles need 24-hour access to the fields. Shoeless House - Please remove your shoes (a farm is a dirty place, and it’s best kept outside). No Smoking - The house and buildings are strictly non-smoking. Please smoke (or vape) away from the house, and toss your butts in the garbage can (which may seem obvious, but we’re always surprised to discover that many smokers mindlessly toss their butts all over the ranch). Water - Please conserve our water (we don’t have our own spring, and purchasing water is quite expensive). -
Advocate Protecting and Sustaining the Unique Lands, Waters, and Biodiversity of West Marin Since 1971
ADVOCATE PROTECTING AND SUSTAINING THE UNIQUE LANDS, WATERS, AND BIODIVERSITY OF WEST MARIN SINCE 1971 ACTION ALERTS, PROGRAMS, EVENTS, VOLUNTEERING & GIVING WINTER 2019 1 Executive Director’s Note MISSION To protect and sustain the unique lands, In West Marin, we are already feeling the impacts of a changing climate. Our sea levels are waters, and biodiversity of West Marin. rising, extreme storms are causing flooding, and extended dry seasons are increasing our risk of catastrophic wildfires. As a result, our communities are left with the difficult task of managing VISION our response and adaptation efforts around this crisis. To provide long-term protection and conservation of the unique ecosystems We can’t count on our federal administration to provide climate leadership; instead we witness and rural communities of West Marin to the active dismantling and weakening of environmental protections and denial of the climate serve as a foundation for environmental crisis. It is left to our local communities to proactively engage to shift policies, raise awareness, protection for future generations. and connect with one another to ensure resilience in these uncertain times. EAC’s long-standing work to protect West Marin’s lands, waters, and biodiversity through GUIDING PRINCIPLES advocacy, engagement, and education has become even more critical, as we face the biggest social and environmental challenge of our time. ADVOCACY Use grassroots strategies to research While our climate emergency is overwhelming and terrifying, we must remain hopeful and and publicize local environmental collaborative, ready to face the challenge instead of focusing on negativity and despair. We can issues facing our community to inform, act locally to advocate for meaningful changes in Marin County and California to mitigate the empower, and educate stakeholders and worst impacts, change behaviors, and address systemic problems.
