Management Notes for this Location:
Rattus rattus was eradicated from Anacapa East in December 2001. The eradication programme was led by Island Conservation and Channel Islands National Park. One application of brodifacoum (25ppm) was carried out aerially and by hand broadcast, at a rate of 15kg/ha. The endemic mouse (see Peromyscus maniculatus ssp. anacapae in IUCN Red List of Threatened Species) was protected by staggering the eradication over the three Anacapa islets, so that a free-ranging population was always present on one or more islets. A captive population was also kept on the island (Howald et al., 2004). A number of measures are now in place to prevent reinfestation: rodent proof storage areas, rodent proof containers, and rodent control at all entry points to the island (Anacapa Island Restoration Plan Progress Report and Work Plan). This was the first aerial application of rodenticide to eradicate rats in North America. For more information on the project and project updates please see: Project update May, 2003
Anacapa East (43 ha) is part of the Channel Islands National Park off the coast of California, USA. Its vegetation is primarily grassy.
