Background

On December 29, 1999, the Service published a rule proposing endangered status for Ambrosia pumila (San Diego ambrosia) in the Federal Register (64 FR 72993). The original comment period closed on February 28, 2000. The comment period now closes on May 30, 2000. Written comments should be submitted to the Service (see ADDRESSES section).

Ambrosia pumila is a herbaceous perennial plant with underground rhizome-like roots. This wind pollinated species is restricted to San Diego and western Riverside counties and from Colonet to Lake Chapala, in Baja California, Mexico. The species is currently known from 13 extant native occurrences in the U.S. Ambrosia pumila is threatened by the following; destruction, fragmentation, and degradation of habitat by recreational and commercial development; highway construction and maintenance; construction and maintenance activities associated with utility easements; competition from non-native plants; trampling by horses and humans; off-road vehicle (ORV) use; and inadequate regulatory mechanisms. Comments from the public regarding the accuracy of this proposed rule are sought, especially regarding:

(1) Biological, commercial trade, or other relevant data concerning any threat (or lack thereof) to this species;

(2) The location and condition of any additional occurrences of this species and the reasons why any habitat should or should not be determined to be critical habitat pursuant to section 4 of the Act;

(3) Aditional information concerning the range, distribution, and population size of this species;

(4) Current or planned activities in the subject area and their possible impacts on Ambrosia pumila or its habitat;
