| Although the quarry trail is off limits to
bikes for now (map),
please be aware that there are two astragalus plants encroaching onto this
trail at one point. There have always been a few dozen astragalus growing
in the area but this year there is a bumper crop of over 70. This plant is
possibly the home of the rare Western Tailed Blue Butterfly.
Avoid disturbing these plants! They can be identified by the cream colored flowers and light green pods (see closeup photo). |
| Letter to the Daily Breeze: Local cyclists help protect butterfly The Concerned Off-road Bicyclists Association of Palos Verdes (CORBA PV) has pitched in to help protect the rare Western Tailed Blue Butterfly. This special insect has been observed at a colony of astragalus plants on the Quarry trail at the Forrestal 
Nature Preserve.Recently, our members noticed that two of these host plants encroach slightly into the trail, and a few plants located off the trail had been stepped on. Although traffic here is very light and the colony is made up of over 70 dispersed plants, we felt that a sign would help inform trails users about the importance of protecting these plants. With approval from the land manager, CORBA PV
designed and erected a sign that will help secure a home for this butterfly.
In addition, we issued a plant alert email to over 140 members and posted
photos with detailed information on our web site mtbpv.org “Plant Alert”.
