Background

The Loch Lomond button celery was listed as endangered under the federal Endangered Species Act in 1985 as an emergency measure due to the threat of

from proposed dredging and filling of the vernal pool.The Loch Lomond Draft Management Plan, CA Dept. of Fish and Game, Sept 1994 p.4 The land was purchased by the CDFG on March 28, 1988, for $46,000 with funds provided by the State Public Works Board and the California Wildlife Conservation Board. A post and rail fence was installed by CDGF to limit access. Historically, the area was used as a recreation field for baseball games, horseback riding, ice-skating, volleyball and cycling and was adjacent to the Loch Lomond Lodge, a popular resort until destroyed by fire on August 14, 1967.

In 1941, Robert Hoover collected the first specimen of button celery, although the plant is named for botanist Lincoln Constance who, together with M.Yusuf Sheikh, collected samples from the vernal pool in 1973. Sheikh continued to search other areas for the button celery as part of his doctoral thesis, but found no other populations. In 1984, California state botanists also conducted a search for other populations with no success. The emergency listing in the ''Federal Register'' by the

of the species. (At the time, the Reserve had the only known population. Since the 1990s, three more populations have been found.) The emergency listing expired on March 29, 1986, and a new proposed rule was submitted by USFWS on March 26 which included public notification and request for comments. A Final Rule was issued and the button celery was federally listed as

on January 22, 1987. The landowner was planning construction of a pool or lake at the site and excavation had already begun, so the disturbed area was graded and reseeded with button celery. Other threats included off-highway vehicles, people treading through the meadow, and illegal dumping. During the rainy season, off-road vehicles are still a problem, and the Department of Fish and Game was surveying the property for installation of new fencing in 2009.
