In addition, the plans provide for management of the reserve lands to protect, restore, and enhance their value as gnatcatcher habitat. However, as discussed above, the status of the gnatcatcher, its coastal sage scrub habitat requirements, and the location of that habitat are already well known, and this information is readily available. Fun Facts Blue-gray Gnatcatchers sometimes beat large insects against a branch before consuming them.

    In these cases, FEMA consults with us to avoid or minimize impacts to gnatcatchers. We acknowledge that in some cases a designation of critical habitat on private lands may provide some benefit to a species by highlighting areas where the species may occur or areas that are important to the species' recovery. However, these programs generally involve rehabilitation or redevelopment of previously disturbed areas that do not contain gnatcatcher habitat. Some of these sage scrubs are publicly owned, but the rest of the sage scrubs are privately owned.
