Governing body Greater Farallones National Marine Sanctuary

Kent Island is a small island in Marin County, California. In 1964 it was proposed for large-scale development including a hotel and marina, but the plan was defeated in 1967. The island is now included in the Greater Farallones National Marine Sanctuary.

Location

The island is located within the Bolinas Lagoon, a salt water inlet of the Pacific Ocean. The island is opposite the town of Bolinas, near Stinson Beach, California, and is surrounded by mud flats at low tide. [3]

On April 18, 2008, Sage Tezak, Bolinas Lagoon Restoration Coordinator of the Gulf of the Farallones National Marine Sanctuary stated in an Advisory Council Meeting that Kent Island's shoreline had historically been dynamic in that it would move, causing the island to change shape. He noted that the appearance of invasive plant species on the island in recent years has stabilized the shoreline, eliminating the gradual movement of the island. [4]

History

Saving Kent Island

In 1964 development on the island was proposed by Bahia Baulines Inc., which had leased 100 acres (40 ha) of underwater tidelands. The plan would have begun by dredging mud from the northern end of the lagoon and depositing it on the island to give it more height and to increase the overall size. The construction phase would have included a hotel and restaurant, both with parking lots, as well as an office, a boat facility and marina for up to 1,500  watercraft, and a helicopter pad.

The plan was terminated in 1967 when Audubon Canyon Ranch, the Nature Conservancy and the Marin Conservation League worked together to save the 110 acres (45 ha) island from the development. Funds were raised to purchase the island and give it to the county on the stipulation that the property remain undeveloped as a nature preserve. The Marin County Board of Supervisors voted to accept the island into the public domain just hours before the Bolinas Harbor District would have acted to condemn the island in court to stop Marin County's conservation effort. [5] [6]

1980s to present day

The island became a part of Gulf of the Farallones National Marine Sanctuary in 1981. In 1998 Bolinas Lagoon was declared one of 17 Wetlands of International Importance in the USA by UNESCO. There are ongoing concerns that the waters around the island are gradually silting, affecting both human activity as well as the flora and fauna of the area. [6] [7]

In 2009, the Marin County Open Space District and County of Marin were funded through NOAA to remove invasive species and restore native vegetation to approximately 23 acres (9.3 ha) of tidal marsh and regionally rare coastal dune habitat, on and around the island. The project will restore nesting habitat for the endangered snowy plover. [8]

Wildlife on and around Kent Island

A wildlife sanctuary, the island is a haul-out spot for harbor seals and their pups. [9] A study of seal behavior on the island showed that the animals were often disturbed by nearby human activity, with people rowing past the island in canoes a primary cause. Humans approaching the seals closer than 100 meters caused the animals to leave the sites much more often than activities by people at a greater distance. [10]

The island is also a known roosting spot for the California brown pelican. [11] Other avian life includes the long-billed curlew, willets, ring-billed gulls, marbled godwits, American avocets, and black-bellied plovers. [12]

The Mud Islands reserve is located within Port Phillip, about 90 km (56 mi) south-west of Melbourne, Australia, lying 10 km (6.2 mi) inside Port Phillip Heads, 7 km (4.3 mi) north of Portsea and 9 km (5.6 mi) east of Queenscliff. The land area of about 50 hectares is made up of three low-lying islands surrounding a shallow tidal 35-hectare (86-acre) lagoon connected to the sea by three narrow channels. The shapes and configuration of the islands change over the years due to movement of sand by tidal currents.

Farallon Islands Group of islands off the coast of California, United States

The Farallon Islands, or Farallones, are a group of islands and sea stacks in the Gulf of the Farallones, off the coast of San Francisco, California, United States. The islands are also sometimes referred to by mariners as the Devil's Teeth Islands, in reference to the many treacherous underwater shoals in their vicinity. The islands lie 30 miles (48 km) outside the Golden Gate and 20 miles (32 km) south of Point Reyes, and are visible from the mainland on clear days. The islands are part of the City and County of San Francisco. The only inhabited portion of the islands is on Southeast Farallon Island (SEFI), where researchers from Point Blue Conservation Science and the U.S. Fish and Wildlife Service stay. The islands are closed to the public.

Richardson Bay arm of San Francisco Bay

Richardson Bay is a shallow, ecologically rich arm of San Francisco Bay, managed under a Joint Powers Agency of four northern California cities. The 911-acre (369 ha) Richardson Bay Sanctuary was acquired in the early 1960s by the National Audubon Society. The bay was named for William A.
