Unit A (South Unit 110)

Major geographic features include the Diablo Range and Caliente Range to the north and east, Sierra Madre Mountains bordering the coast, and prominent valleys including Buena Vista, Cuyama, and San Carlos Bolsa. Lake San Antonio and Lake Joallan provide reliable water reference points and potential hunting access corridors. Key ridge systems like Buttonwillow Ridge and the Oat Hills serve as natural travel corridors and glassing vantage points.

Gaviota Pass and Cuesta Pass offer navigation reference points. The Kern River drainage and Lopez Creek system create significant north-south corridors where water concentrates wildlife movement.

The overwhelming majority of hunting occurs below 5,000 feet on rolling grassland and chaparral-covered slopes with scattered oak woodlands and sagebrush. Lower elevations feature open plains, agricultural areas, and coastal benches with minimal tree cover. As elevation increases into the foothills and lower mountain ranges, vegetation becomes denser with ponderosa pine, Douglas fir, and mixed oak forests appearing above 4,000 feet.

The sparse overall forest coverage means most terrain remains relatively open, making glassing effective across large portions of the unit. Seasonal water availability shapes habitat use significantly across these elevation zones.

A dense road network of over 60,000 miles provides extensive access, including multiple highways and well-maintained ranch roads. This connectivity means the unit is accessible but also experiences significant hunting pressure on public lands, particularly near road access points and in lower elevations. Private ranches control most terrain, requiring careful navigation and permission to hunt much of the unit.

Pressure tends to concentrate along major roads and near established public access areas. Successful hunting often depends on identifying less-pressured public parcels away from primary road corridors and understanding where public land pockets exist within the private ranch landscape.

This massive unit encompasses over 26,000 square miles of central California's coastal and interior regions, stretching from near sea level to over 6,800 feet elevation. The unit includes the Diablo Range, Caliente Range, and Sierra Madre Mountains as primary topographic features, with agricultural valleys, coastal benches, and ranch country occupying much of the lower elevations. The landscape transitions from Pacific-facing coastal terrain inland through agricultural zones toward interior foothill and mountain country.

The unit's size and complexity demand careful planning—it includes segments of public land interspersed within predominantly private ranches and agricultural operations.

Water sources are moderate but concentrated in specific drainages, making creek access critical to hunting strategy. The Kern River system provides reliable water along its course, while Lopez Creek, Tecuya Creek, and Buena Vista Creek support wildlife in their respective drainages. Springs are scattered throughout—LaJolla Springs, Squirrel Spring, Oak Springs, and Willow Spring offer water access in upper elevation areas.

Summer and early fall pressure on limited water sources concentrates deer and mule deer around reliable seeps and creek systems. Understanding drainage patterns and spring locations determines effective glassing and route planning throughout the unit.

Mule deer and white-tailed deer occupy this unit across varying elevations and habitat types. Lower elevation open country and agricultural zones attract deer year-round, with seasonal elevation shifts as conditions change. Oak woodlands and chaparral-covered slopes provide cover and feed throughout the foothills.

Early season hunting focuses on higher elevation pockets where cooler temperatures and available water concentrate animals. Rut activity typically moves deer into more open terrain for visibility and movement. Late season pressure forces animals into scattered timber and protected drainages.

Success requires locating public land access, glassing open slopes during morning and evening hours, and understanding water availability patterns to predict deer concentration areas across this large, complex unit.
