Which endangered species has the greatest overlap with agricultural areas in California?

The San Joaquin kit fox has the greatest overlap with agricultural areas in California among the listed endangered species. This species primarily inhabits the San Joaquin Valley, which is notably dominated by a variety of agricultural practices, including row crops and orchards. The adaptation of the kit fox to the modified habitats of agriculture makes it more likely to be found in these areas compared to the other species mentioned.

In contrast, species like the California red-legged frog, Mission blue butterfly, and Sierra Nevada red fox have more specific habitat requirements and are often found in more natural or less disturbed environments. The California red-legged frog prefers aquatic habitats, while the Mission blue butterfly is heavily associated with certain plant species that are primarily in grassland and coastal environments. The Sierra Nevada red fox, on the other hand, is adapted to higher elevation, forested regions. Thus, their interactions and overlaps with agricultural landscapes are much less significant in comparison to the San Joaquin kit fox.
