Eryngium aristulatum var. parishii


San Diego button celery is an annual herb from the parsley family and is often recognized by its low spreading appearance and greenish flowers. It once occurred in many vernal pool systems, but by the late 1980's 23% of vernal pool systems had been destroyed, leaving remaining populations impoverished.

Vernal pools, one of California's most threatened habitats, are natural depressions that fill with water during the winter and spring and dry up during the summer. Plants that live in the vernal pool ecosystem are specifically adapted to their ephemeral pool environment. The pools are too wet in winter for upland plants and too dry in summer for aquatic plants. Like other vernal pool plant species, Eryngium aristulatum germinates during the flooding period and blooms as the pools dries.

Distribution & Occurrence

State Range
  California
State Range of  Eryngium aristulatum var. parishii
Habitat
  Found in vernal pool systems and salt marshes.

San Diego button-celery (Eryngium aristulatum) is associated with other endangered Vernal Pool species including, Burke's goldfields (Lasthenia burkei, California Orcutt grass (Orcuttia californica), San Diego mesa mint (Pogogyne abramsii) and Sebastopol Meadowfoam (Limnanthes vinculans).

Distribution
  Santa Rosa Plateau in Riverside County.

Number Left
  This species is known only from 4 populations on the Santa Rosa Plateau containing fewer then 1,000 individuals. (Dudeck and Associates Inc. 1999)

Conservation, Ecology & Research

Ecological Relationships
  None known.

Threats
  Threats include urban and agricultural development, alteration of drainage patterns, mowing and livestock grazing, off-road vehicles, trash dumping, and competition from weedy, non-native plants.

Current Research Summary
  In 1993, Rancho Santa Ana Botanic Garden created 30 small vernal pools as part of their plant display as well as part of a long term gene flow study by the Garden's Research Department and Endangered Species Program. Artificial vernal pools have also been created by the University of California's Botanic Garden. Because these pools require careful tending it has been concluded that recreated pools are not self-sustaining and therefore not a viable option to replace the loss of naturally occurring vernal pools.

Current Management Summary
  • Under the terms of a settlement agreement approved Monday, July 23, 2001 by the U.S. District Court in Sacramento, the U.S. Fish and Wildlife Service (Service) will map critical habitat for 15 endangered and threatened species that are dependent on vernal pool wetlands in California. The critical habitat designation will add protection to California's remaining vernal pool habitat.
• All four remaining populations and substantial habitat that may support this species are preserved within the Santa Rosa Plateau Preserve. (Dudeck and Associates Inc. 1999)

Research Management Needs
  Population monitoring, reproductive/seed biology and general ecology of vernal pool dynamics would aid in the conservation of this and associated species.
