Option B: Labeled the preferred option. The island's land area is home to the largest seabird colony of the contiguous United States. A trip is planned for 2015 for scientists to return to Henderson and study the impact of rat eradication on seabird and other species populations. Home to whaling and sealing fleets 100 years ago, the primary European inhabitant today is the Norway brown rat—a resident responsible for the ongoing devastation of South Georgia’s bird population. The toxicant compound Brodifacoum-25D Conservation is a secondary anticoagulant rodenticide known to have a serious risk of non-target and secondary poisonings.

The A24 trap was developed for the purpose of sustained conservation by effectively targeting invasive rodent populations without putting other wildlife at risk in the process. every animal on the islands other than the mice). Whether or not 1,000 gulls actually die if this plan is carried out, the fact that it allows for as many as 1,000 poisoned gulls that could fly to and die on Marin, Sonoma and San Franciso beaches, that will be eaten by marine mammals and other marine species, and by land-based predators, all of which will also be poisoned, is not “acceptable” to WildCare. Feds Withdraw Plan to Drop Rat Poison on Farallon Islands – for Now. The document about the Rat Island project, “Critical Evaluation of Nontarget Mortality” (PDF), further demonstrates that, while most poisoning of non-target animals resulted from predation upon bait-poisoned rodents, gulls and other animals were found to have also consumed the pellets and to have died from primary poisoning from brodifacoum. SAN FRANCISCO (KRON) – There’s a plan in the works to drop 1.5 tons of poison pellets on the Farallon Islands — A move aimed at eliminating a rodent … A diverse population of seal species also make use of the isolated island chain for living on and pupping.

What we disagree with is that the only two alternatives to help and protect the fragile ecosystem on the Farallon Islands are to a) do nothing or b) drop 2,917 pounds of poisoned bait on the islands. With this number of gulls killed, their modeling predicts that Western Gull populations after 20 years would be about the same whether or not the project goes forward. After multiple Commissioners asked probing questions of Fish & Wildlife service representatives, they proposed to withdraw their request for consistency for the time being. In other isolated island habitats, bird species have rebounded quickly from rat eradication. This project poses severe risks and will have long term impacts to ALL the living resources within the public trust. When the winter season causes mouse numbers to plummet, the owls have taken to preying on the endangered ashy storm petrels in substitute. rats (Rattus spp.). The island also is the wintering ground of several species of migrants, and regularly attracts vagrant birds (about 400 species of bird have been recorded on or around the island). Over the past decade, WildCare has tested hundreds predatory patients in our Wildlife Hospital for exposure to rodenticides from having eaten poisoned rodents. USFWS requested a “consistency determination” from the Commission, and that item was number 14a on the meeting agenda. The Farallon Islands are only 26 miles west of San Francisco but feel remote.

That is because things have been very quiet regarding the Farallon Islands aerial rat poison drop. There is not currently an estimate of when that record will be published. Before the service applies for those permits, it will issue a record of decision that describes the alternatives the agency considered and discusses its plans for mitigation and monitoring. 3. The purpose of this collaboration was to innovate an alternative to using labor intensive, single set traps for dealing with invasive rodent populations. . Spread the word! The aerial broadcasting of toxic rodenticide pellets over the entire landmass of the Farallon Islands does not fit these criteria and should not even be considered in the eradication proposal. This is called secondary poisoning, and is a harsh reality of pest eradication programs such as this one. It is WildCare’s position that, if control of House Mouse populations is necessary, responsible, non-toxic and environmentally sustainable approaches must be used.

These islands (Southeast Farallon and Maintop Island) off the coast of San Francisco are the winter water playground of adult great white sharks measuring 15 to 20 feet long. Indirect Impact. Tests done by USFWS to determine the efficacy of gull hazing methods were incomplete as the tests did not include dumping 2,917 pounds of edible bait on the islands, nor did they arrange for thousands of dying mice to be present. Opponents cite concerns that the poisons will endanger a range of wildlife on or near the islands, while proponents say the project will help threatened seabirds and the island ecosystem. Rodents that have consumed brodifacoum do not die immediately. Coalitions both in favor of the poison drop, and those of us opposed to it, are gearing up to sway public opinion. With the A24 traps being kept on the island, re-invasion of rats has been prevented. Without any natural predators on the islands, the mice thrived and bred with few challenges. Poison is the easy way out, but the easy way is not always the best way. Numerous aquatic species will be exposed to the poison creating unknown consequences. The fact that the trap is self-resetting the trap is always be ready to strike another pest. Eradicate the mice through an aerial broadcast of rodent bait containing Brodifacoum-25D Conservation.
