Navarretia fossalis


Navarretia fossalis is an annual herb found in vernal pools and other shallow freshwater depressions in northwestern Baja, California (USFW 1994). The whitish lavender flowers are arranged in flattened clusters, bloom from April to June and produce two celled capsules of reddish brown seeds (Wiggins 1980).

Distribution & Occurrence

State Range
  California
State Range of  Navarretia fossalis
Habitat

Distribution
  From northwestern Los Angelos County and western Riverside County south, through coastal San Diego County to San Quentin in northwestern Baja California, Mexico. (USFWS 1998)

Number Left
  Fewer than 30 populations exist in the United States, a few of which contain hundreds of thousands of plants during wet years, but the majority of which contain fewer than 1,000 individuals. (USFWS 1998)

Conservation, Ecology & Research

Ecological Relationships
  Ecological relationships are unknown.

Threats
  Threats include agriculture, fragmentation, grazing and urbanization.

Current Research Summary
  None known.

Current Management Summary
  In 1999, the Western Riverside County prepared a Multiple Species Habitat Conservation Plan for: The County of Riverside Transportation and Land Management Agency. The plan includes designating larger areas for species/habitat protection and also species analyses. (Dudeck and Associates Inc. 1999)

Research Management Needs
  Population monitoring and general ecology would be useful in conservation efforts.
