are not limited to) ridges, canyons, riparian areas, and open spaces to travel between their <br />required habitats. <br />As background, it is important to note that "movement corridors" depends on the species in <br />question and its consistent use patterns. Animal movements generally can be divided into three <br />major behavioral categories: <br />• Movements within a home range or territory; <br />• Movements during migration; and <br />• Movements during dispersal <br />While no detailed study of animal movements has been conducted for the project site, knowledge <br />of the site, its habitats, and the ecology of the species potentially occurring onsite permits <br />sufficient predictions about the types of movements occurring in the region and whether or not <br />proposed development would constitute a significant impact to animal movements. <br />This site, while long undeveloped, has long supported landscapes that were of low wildlife value <br />as it was historically an intensely farm azea and now supports primarily ruderal vegetation. <br />While a number of relatively common reptiles, birds, and mammals use the site at times, it does <br />not provide a conduit whereby these species (or others) would traverse it while traveling from <br />higher quality habitat patches. It is important to note, that a corridor needs to "link" patches of <br />higher quality habitat and at best, this site is best characterized as surrounded by developed <br />habitats. Therefore, this site does not function significantly as a movement corridor. <br />2.3 SPECIAL STATUS PLANTS AND ANIMALS <br />Several species of plants and animals within the state of California have low populations and/or <br />limited distributions. Such species may be considered "rare" and aze vulnerable to extirpation as <br />the state's human population grows and the habitats these species occupy are converted to <br />agricultural and urban uses. As described more fully in Section 3.2, state and federal laws have <br />provided the California Department of Fish and Game (CDFG) and the U.S. Fish and Wildlife <br />9 <br />Ironwood 55+ Biotic Evaluation Live Oak Associates, Inc. <br />
