The endangered woollystar plant is in bloom this month in the Santa Ana River Wash.

Endangered or threatened species in the Santa Ana River Wash

Santa Ana River woollystar: Listed as an endangered species by the U.S. and California, which means killing or possessing the plant is prohibited. Some of the woollystar’s habitat was disturbed by the construction of the Seven Oaks Dam in the late 1900s and early 2000s.

  The plant grows no taller than 3 feet. It has light grey-green stems and leaves with bright blue funnel-shaped flowers. It flowers between May and August, most heavily in June, and fruits from July to mid-October.

  The exchange plan would increase the Santa Ana River Woollystar Preservation Area to 574 acres. A 20-acre corner of the preservation area once disturbed by lumber mill would be designated a mining area in exchange for 47 acres owned by Robertson’s Ready Mix that is more suitable for the plant.
