RARE PLANT POPULATION SEARCHES AND MAPPING
Management Objective:
To maintain or increase the numbers of rare plant individuals and populations.
Methods:
The overall goal is to compile and maintain a current and complete map of selected
rare plant species on the island. Existing rare plant location data has been
compiled and standardized. Existing information will be obtained from Wrigley
Memorial and Botanic Garden and Santa Barbara Botanic Garden botanists. Existing
rare plant maps were distributed to appropriate Conservancy employees, on which
they drew in locations not currently mapped. The Data Dictionary used with our
Trimble GeoExplorer units to record appropriate information about each plant
population has been refined. Ongoing efforts to map rare plant locations as they
are seen continue. Focused searches will be conducted annually for particularly
rare plants. In 2001, the Federally Endangered Pentachaeta lyonii was targeted,
which has not been recorded since 1931. Suitable habitat in the general area
of the original population was identified and searched by general reconnaissance.
The plant was not located.
Collection Frequency:
Ongoing mapping efforts. Focused rare plant searches are conducted once per year
within their blooming period. |
