Zone D19, California

Mountainous Southern California terrain in the San Jacinto and Santa Rosa Mountains (San Bernardino National Forest), grading down to surrounding desert. The broader San Bernardino National Forest ranges from high peaks (San Gorgonio Mountain, the highest point in Southern California at 11,503 ft) down to semi-desert; HuntScore characterizes the zone's public lands as predominantly steep. Exact zone-specific elevation bands were not found in a source, so they are not stated here.

Zone D19 is accessed primarily via SR-243 (Banning-Idyllwild Panoramic Highway, entering from I-10 at Banning) and SR-74 (connecting Hemet to the west and Palm Desert to the east through the Mountain Center/Garner Valley area); the zone is broadly bounded by I-10 to the north, Hwy 111 to the east, Hwy 78 to the south, and Hwy 79 to the west. The bulk of public land is administered by the San Bernardino National Forest, San Jacinto Ranger District (Idyllwild station: 25905 Hwy 243, (909) 382-2921), with additional BLM lands and the Santa Rosa and San Jacinto Mountains National Monument; no Adventure Pass is required when parked on Forest roads in the San Jacinto District during hunting season. Key named access roads include Forest Road 6S13 (Thomas Mountain Road), a year-round dirt route running from Anza south to Garner Valley with dispersed yellow-post campsites usable as base camps, and Apple Canyon Road (off Hwy 74 near Lake Hemet) which leads to the Spitler Peak Trailhead roughly 2.5 miles from the highway; the Cactus Spring Trail (5E01) trailhead at Pinyon Flat Campground off Hwy 74 provides foot access into the southern Santa Rosa range. Hunters should note that the San Jacinto Wilderness and Santa Rosa Wilderness fall within the zone boundaries and contain State Game Refuges 4D and 4G respectively — these areas are closed to deer hunting — so hunters must confirm exact refuge boundary locations before accessing these non-motorized wilderness areas.

Within the San Bernardino National Forest the zone spans a range of cover types described by USFS as mixed conifer forest and oak woodland at higher elevations, transitioning through pinyon-juniper stands and chaparral to semi-desert at lower elevations. Zone-specific stand-by-stand vegetation breakdowns were not located in a source.

HuntScore reports the D-19 deer population as stable to slightly declining and considerably below historical levels. The rut can begin as early as late October and run through late December (per HuntScore). General mule/black-tailed deer ecology in this Southern California mountain-to-desert system supports elevation-driven seasonal movement, with deer using higher conifer/oak habitat in summer and lower chaparral/desert-edge zones in colder months; precise zone-specific migration corridors were not found in a source and are not asserted.
