Napa-Sonoma Marshes Wildlife Area Directions to Units
Napa-Sonoma Marshes Wildlife Area Directions to Units It is highly recommended that you print out a map of the wildlife area prior to accessing. Huichica Creek (1,091 acres) From Hwy 12/121 turn south on Duhig Road and proceed approximately 2 miles then turn left on Las Amigas Road. Follow Las Amigas Road east until it connects with Buchli Station Road then turn right (south) on Buchli Station Road and follow the road through the vineyard areas until you cross the rail road tracks adjacent to CDFW parking lot. All visitors are encouraged to walk existing trails, levees and service roads south of the railroad tracks. Napa River (8,200 acres) The southern ponds (Ponds 1 and 1A) can be viewed from State Hwy. 37 which is located just north of San Pablo Bay. Where the Mare Island Bridge crosses the Napa River travel west 3.5 miles to a parking lot and locked gate on the north side of the highway with an opening provided for pedestrian access. The pedestrian access point in the gate allows foot traffic north to the large metal power transmission towers that bisect the pond. Within Ponds 1 and 1A, beyond the power towers to the north is a zone closed to hunting and fishing. The remaining portion of the Napa River Unit is to the north of these ponds, between South Slogh and Napa Slough (refer to area map), and is accessible only by boat. Ringstrom Bay (396 acres) The unit can be viewed from Ramal Road. From State Hwy. 12/121 take Ramal Road south. -

Accepted on 16 March 2015. ABSTRACT: The lB ack Kite Milvus migrans is a widespread migratory raptor found over much of the Old World. Vagrants have been widely recorded far from its main migratory routes. Here, we report the occurrence of a Black Kite in the Brazilian Saint Peter and Saint Paul Archipelago (SPSPA) in April/May 2014. The bird remained for 32 days in the SPSPA, disappearing at the end of the rainy season. It looked healthy for most of this period and was once seen preying on a seabird chick. -
Manual Removal of Cape Ivy at Audubon Canyon Ranch's Bolinas
Manual Removal of Cape Ivy at Audubon Canyon Ranch’s Bolinas Lagoon Preserve Len Blumin ([email protected]) Daniel Gluesenkamp ([email protected]) Introduction Cape ivy (Delairea odorata), an invasive vine from South Africa, has invaded many riparian areas of coastal California, and threatens thousands of acres of valuable habitat. This poster presents our 6 year experience in removing Cape ivy (CI) along a coastal creek and floodplain, using volunteer labor and a "modified scorched earth" approach. The Project – Audubon Canyon Ranch manages a system of nature preserves. Cape ivy appeared in ACR's Bolinas Lagoon Preserve before 1960 and by 1994 had invaded 6 acres in the flood plain of Volunteer Canyon (VC). In 1994 CI was identified as the highest priority invasive plant on the preserve. Encouraged by a successful CI removal pilot project in 1995, we set out to completely remove CI from Volunteer Canyon. The Site – The creek in Volunteer Canyon drops steeply through a mixed evergreen forest, flattens out as it enters the flood plain, then empties into Bolinas Lagoon. The canyon was logged from 1850 to 1875, supported ranching, farming and residential uses until the 1960s, and since 1968 has been used as an environmental education center and for ACR staff housing. While the preserve supports rich biodiversity and the canyon's slopes have few exotic plants other than non-native grasses, the flood plain is invaded by Cape ivy, Vinca major, and other non-indigenous plants listed in Table 1. Cape Ivy growth – By the mid 1970's the core Cape ivy population had covered 6.5 acres, as shown on the map. -
Sonoma Creek Baylands Strategy - Executive Summary May 2020 Contact: [email protected]
Sonoma Creek Baylands Strategy - Executive Summary May 2020 Contact: [email protected] Introduction Prior to the 1850s, the Sonoma Creek baylands were a vast mosaic of tidal and seasonal wetlands. Fresh water, sediment, and nutrients were delivered from the upper watershed to mix with the tidal waters of San Pablo Bay, creating a small estuary teeming with life. Floods along Sonoma Creek and Schell Creek spread out in an alluvial fan in the region south of present-day State Route (SR) 121, creating distributary channels and depositing sediment. During the late 19th and early 20th centuries, the Sonoma Creek baylands, along with 80 percent of wetlands around San Francisco Bay, were diked and drained for agriculture and other purposes. This created discrete parcels and simplified creek networks. Flow of water and sediment across the alluvial fans was blocked and confined to the creek channels. As a result, portions of Schellville and surrounding areas in southern Sonoma County are frequently flooded during relatively small winter storm events, when flows overtop the banks of Sonoma and Schell creeks, resulting in road closures at the junction of SR 121 and SR 12 that affect travel and public safety. Much of what used to be tidal marsh has been transformed into other habitat types including diked agricultural fields. Narrow strips of tidal marsh have developed adjacent to the tidal slough channels that run between the diked agricultural baylands. Development within the Sonoma Creek baylands continues despite the chronic flooding that is caused by filling and fragmentation of the floodplain. Flooding, and loss of habitat, species, and ecological function will increase with climate change-driven sea level rise and increased storm intensity. -

San Pablo Bay and Marin Islands National Wildlife Refuges - Refuges in the North Bay by Bryan Winton
San Pablo Bay NWR Tideline Newsletter Archives San Pablo Bay and Marin Islands National Wildlife Refuges - Refuges in the North Bay by Bryan Winton Editor’s Note: In March 2003, the National Wildlife Refuge System will be celebrating its 100th anniversary. This system is the world’s most unique network of lands and waters set aside specifically for the conservation of fish, wildlife and plants. President Theodore Roosevelt established the first refuge, 3- acre Pelican Island Bird Reservation in Florida’s Indian River Lagoon, in 1903. Roosevelt went on to create 55 more refuges before he left office in 1909; today the refuge system encompasses more than 535 units spread over 94 million acres. Leading up to 2003, the Tideline will feature each national wildlife refuge in the San Francisco Bay National Wildlife Refuge Complex. This complex is made up of seven Refuges (soon to be eight) located throughout the San Francisco Bay Area and headquartered at Don Edwards San Francisco Bay National Wildlife Refuge in Fremont. We hope these articles will enhance your appreciation of the uniqueness of each refuge and the diversity of habitats and wildlife in the San Francisco Bay Area. San Pablo Bay National Wildlife Refuge Tucked away in the northern reaches of the San Francisco Bay estuary lies a body of water and land unique to the San Francisco Bay Area. Every winter, thousands of canvasbacks - one of North America’s largest and fastest flying ducks, will descend into San Pablo Bay and the San Pablo Bay National Wildlife Refuge. This refuge not only boasts the largest wintering population of canvasbacks on the west coast, it protects the largest remaining contiguous patch of pickleweed-dominated tidal marsh found in the northern San Francisco Bay - habitat critical to Aerial view of San Pablo Bay NWR the survival of the endangered salt marsh harvest mouse. -
