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 show was originally broadcast on KWMR in Point Reyes Station, California. Thanks for listening! (Music) Jennifer Stock: Welcome to another edition of Ocean Currents. I’m your host Jennifer Stock. On this show we talk with scientists, educators, fishermen, explorers, policymakers, ocean enthusiasts, kids, authors and more all uncovering and learning about the mysterious and vital part of our planet, the blue ocean. I bring this show to you monthly from NOAA's Cordell Bank National Marine Sanctuary, one of four National Marine Sanctuaries in California all working to protect unique and biologically diverse ecosystems. Just offshore of the KWMR listening area, on the West Marin coast, are the Greater Farallones and Cordell Bank National Marine Sanctuaries which together protect 4,581 square miles of rocky shorelines, sandy seafloors, rocky banks, deep sea canyons and maritime landscapes and artifacts. I’ve been off the air for a while and I’m so excited to dive back into ocean interviews to share with you listeners. I’m always open for suggestions for shows and interviews, so just a little promo at the beginning of the show. Please let me know what you want to hear about. You can email me at [email protected]. It’s a fresh year and I’m just thinking about what we’ll be discussing on Ocean Currents. -

And again in some shadowy future the surf will have ground these Highway 1 snakes along the lip of the continent, rocks to sand and will have returned the coast to its ear- winding past the ridges, hills and cliffs thrust upward lier state. And so in my mind’s eye these coastal forms and out of the ocean over millions of years by two plates merge and blend in a shifting, kaleidoscopic pattern in touching. In geologic time, what’s visible to our eyes has which there is no finality, no ultimate and fixed reality— all happened rather quickly. Within the timeframe of the earth becoming fluid as the sea itself.” American imperium, little more than a century and a half Since the historic deluges of California’s wettest win- in coastal California, the landscape seems permanent, ter, a year or so after the state’s driest winter, Highway 1’s enduring in this exact form until a storm crumbles a part steep embankments have been belted together in places of the cliff bearing Route 1 back into the sea. -

Sleepy Hollow Homeowners Association May 3, 2013 Board of Supervisors of Marin County 3501 Civil Center Drive San Rafael, CA 94903-4157 Re: Stream Conservation Area (SCA) Proposed Amendments to the Development Code Honorable Members of the Board of Supervisors: INTRODUCTION The Sleepy Hollow Homes Association (SHHA) objects to the proposed changes to Chapters 22.33 (Stream Protection) and 22.63 (Stream Conservation Area Permit) as they would apply to the residents of the unincorporated portion of San Anselmo known as Sleepy Hollow. We ask that the County exempt and/or delay implementation of any changes to Chapters 22.33 and 22.63 as to the city-centered corridor streams, including Sleepy Hollow. The SHHA supports implementation of the proposed amendments to the San Geronimo Valley, to protect wildlife habitat in streams where Coho Salmon currently exist. The SHHA supports regulations to ensure the health and survival of the species in these areas. The SHHA recognizes the urgency of this matter to the San Geronimo Valley, both for the survival of the endangered and declining Coho population and for the property rights of the affected residents who are currently subject to a building moratorium. -

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). -

Sea Level Rise Adaptation Report Marin Ocean Coast
Marin Ocean Coast Sea Level Rise Adaptation Report Marin County Community Development Agency February 2018 Collaboration: Sea-Level Marin Adaptation Response Team Marin County Community Development Agency February 2018 | Marin County, CA | marinslr.org A Call to Action for West Marin Residents West Marin is abundant with natural resources that are integral to its cultural identify as demonstrated by the long heritage of open space preservation and appreciation. Federal, state and local parklands abutting the Pacific Ocean provide a retreat from the hustle and bustle of Bay Area living. Coastal bluffs, beaches, wetlands, and more draw millions of international visitors for surfing, birding, kayaking, hiking, picnicking and more. Protected ranchlands are stewarded by multi-generation family farming operations which feed the region with milk, cheese, yogurt, butter, ice- cream and other products. Nestled within these vast swaths of open space are small but mighty communities that serve as both visitor hubs and homes to residents who cherish and value the unique sense of place. Climate change presents unprecedented threats to West Marin. Wetlands and beaches could be drowned with rising waters, and native plants and animal populations could plummet from changes in temperature and precipitation, ocean acidification, invasive species, and more. Coastal flooding and erosion threaten homes, roads, and utilities that are critical to the long- term sustainability of West Marin. Spearheaded by the Marin County Community Development Agency in 2014, Collaboration: Sea Level Rise Adaptation Response Team (C-SMART) is a partnership based community planning approach to solve some of these challenges. The Marin Ocean Coast Sea Level Rise Vulnerability Assessment analyzed the vulnerabilities of natural and built assets from near- to long-term combined sea level rise and storm scenarios. -
