8-13D-9-15: VEGETATION:
General Vegetation: The Hidden Springs site is composed of three (3) general vegetative zones:
• The moderate to steep slopes, ridges and gulches that are covered with sagebrush grass vegetation;
• The Dry Creek Valley bottomland, which has been converted to agricultural uses; and
• The narrow riparian zones along Currant Creek, McFarland Creek and Dry Creek.
The narrow riparian zones are fairly lush and dominated by large woody species including birch, various willows and red osier dogwood. Hackberry and chokecherry occur in the lower to midslope positions. Forbs includes those that are commonly associated with the foothill's environment. These are miner's lettuce, cleavers, Clematis ligusticifolia, and poa species, sticky geranium, stinging nettle, water pimpernel, cinquefoil and horsetail as well as sedges, grasses, bulrush and alfalfa.
Rare Plants: Rare plants studies were conducted in 1994 and 1999 as part of the site analysis and a report is included in the appendix to this community plan submittal. The reports discuss the isolated populations of Aase's onion that occur in two (2) areas on the upper, south facing slopes north of Dry Creek and at the southern portion of the property above Seaman's Gulch Road. In addition, the 1999 study revealed additional populations of Aase's onion and Wilcox's primrose on or immediately adjacent to the one hundred twenty (120) acre annexation area located at the southern portion of the site, which has been reduced to ninety-seven (97) acres due to the transfer of twenty-three (23) acres to the Cartwright Ranch planned community in 2007.
