Conservation Significance

Conolly Ranch

The Preserve is located within the rolling hills of the eastern Coast Range and set within a larger privately owned cattle ranch.  The Preserve’s habitat consists of annual grassland typical of the area.  There is a stock pond on site that remains inundated even in severe drought years that provides habitat for both California tiger salamander (Ambystoma californiense) and California red-legged frog (Rana drayontii) and is free of non-native predatory fish and bullfrogs.  The surrounding grasslands provide habitat for San Joaquin kit fox (Vulpes macrotis mutica).

Our Work

CNLM holds a conservation easement and is responsible for monitoring the management of the site for the benefit of California tiger salamander, California red-legged frog, and San Joaquin Kit Fox.  Cattle grazing is used to maintain short-grass habitats that are essential for these species.  ThConnolly Ranche purpose of the conservation easement is to help ensure that the property will be retained in perpetuity in open space condition and prevent any use of the property that will impair or interfere with conservation values of the Preserve.

Public Access

Due to the vulnerability of the species and habitats that exist on this preserve, it is not open to the public.
