Rank Reasons

Endemic to California, Galium hardhamiae is known from about 24 occurrences in Monterey and San Luis Obispo Counties. Twelve of these are historical, though it is likely many of these are still extant. The numbers of plants and acreage covered are data not currently well understood. Galium hardhamiae occurs on public lands and private lands including Hearst Corp lands which may now be protected.

Range Extent Comments

This California endemic occupies a small area in adjacent Monterey and San Luis Obispo counties.

Occurrences Comments

Known from 23 element occurrences, 12 of which are historical (more than 20 years since they were seen). However, some or all of the historical occurrences may still be extant.

Threat Impact Comments

Few threats are listed for any element occurrence. One EO lists road building as a threat. Many are too remote to have threats. Some are on DOD-Ft. Hunter-Liggett lands where military operations could threaten. Some populations are known from former Hearst Corp lands which may now be de facto protected.
