Fish & Wildlife Service prepared a Recovery Plan for the California least tern in 1985, and in 2006 reviewed the status of recovery efforts to date, finding that that there are enough pairs of terns to meet the recovery goals of the 1985 plan, significant risks to the species still exist. Survival Adaptations. The subspecies has been listed as endangered since 1972 (California Department of Fish and Game 1972, US Bureau of Sport Fisheries and Wildlife 1973).

[3] Keane Biological Consulting. The successful and continued recovery of the California Least Tern population is in large part a result of intensive management of a limited number of sites; without which it is unlikely that even the observed level of recovery would have occurred. The California least tern (Sterna antillarum browni) nests in colonies on the Pacific coast of California and Baja, Mexico on relativey open beaches where vegetation is limited by the tidal scouring [1]. California least tern (Sterna antillarum browni); and the Federally threatened marbled murrelet (Brachyramphus marmoratus), southern sea otter (Enhydra lutris nereis), and bull trout (Salvelinus confluentus) and their designated critical habitat.

Mengel (1965) did not recognize S.a. anthalassos at Bell I *12*. such as landfills and airports (California Least Tern Recovery Team 1977). We have to go through a legal process(45 KB PDF) to make the change. As biologists continue to work to recover California least terns to healthy population levels, efforts are underway to protect current nesting areas using signage, fencing, chick banding and other habitat enhancement measures. Both species are protected under the federal Endangered Species Act. When placed on the endangered species list in 1970, just 225 nesting tern pairs were recorded in California [2]. The California least tern is a subspecies of least terns, which likely got their name because they’re the smallest terns. Its downlisting and delisting criteria incorporate the total population size, number of colonies, geographic distribution, population viability, and management status. Its body is slate grey above and white below, with the pointed wings and forked tail characteristic of most terns. Portland, Oregon. Nelson, Chase).

Since 1984, the number of California Least Tern pairs in the Alameda colony has increased by 9.7% per year, but the colony size appears to have stabilized in the last decade.. To avoid humans, some tern colonies nest at more inland mudflat and dredge fill sites, which appears to make them more susceptible to predation by foxes, raccoons, cats and dogs. U.S. The 1990 Recovery Plan for the Interior Population of the Least Tern, from the FWS, notes that the recovery objective is delisting of the population, perhaps as early as 2005 if recovery criteria are met.

A portion of the increase in the 1970s is attributable to expansion and greater consistency in survey effort, but greatest increases occurred from 1980 to the present. In the Act, the term “species” includes “any subspecies of fish or wildlife or plants, and any distinct population segment [DPS] of any species of vertebrate fish or wildlife which interbreeds when mature.” Therefore, we use the term “species” to refer … 2007.

My name is Danny and I'm a 7th grade student in San Diego, California. To be viable, a colony must have at least 20 breeding pairs, a three year mean reproduction rate of >= 1.0 fledglings/pair, and be fully protected under a long-term management plan. 2316. (S. a. antillarum) least tern colonies which can move in response to newly created or removed nesting habitats (from storms or floods), California LETE colonies are restricted to existing sites, and all potential habitat is likely necessary to support population viability. 2006.

In 2018, Least Terns nested at Eden Landing Ecological Reserve, a The Western Snowy Plover and The California Least Tern are both native to the Pacific Coast, creating nesting sites up and down the coast of California and in to Mexico. Restricting access to nesting sites on beaches is a common practice and reduces disturbance to breeding pairs while also keeping out certain predators. Under the Act, we are required to conduct a review of all listed species at least once every 5 years (5-year review) to review their status and determine whether they should be classified differently or removed from listed status. Over 70% of California least terns reside on just five nesting sites and the reproductive rate of the species remains lower than … FOOD. [1] USFWS. Terns require an undisturbed stretch of sparsely vegetated sandy or gravelly ground near a lagoon, estuary or bay in order to nest. We review existing data on the distribution of the Least Tern, Sternula antillarum along the Brazilian coast, based on the literature and museum specimens, and present results of a year-long study (October 2008 to September 2009) on the seasonal abundance of this species on a large tidal flat area, Cajuais Bank, in the State of Ceará, north-eastern Brazil. Fish and Wildlife Service, Portland, Oregon. The largest 2004 sites were at Camp Pendleton (21%), U.S. Navy lands at San Diego Bay (16%), Los Angeles Harbor, Pier 400 (15%), Point Mugu (8%), Alameda Point (6%), Batiquitos Lagoon Ecological Reserve (6%), Huntington State Beach (5%), and Tijuana Estuary (5%). Least terns in Montana will often be found sharing sandbars with the piping plover, a threatened species. It could formerly be found in great abundance from Moss Landing, Monterey County, California to San Jose del Cabo, southern Baja California, Mexico.
