Please note the addendum/correction below

Our chapter's plant lists are usually for locations in Placer or Nevada County. We are publishing a newly compiled list for Boggs Lake in Lake County because it is such a unique place, and because it was the site of one of our field trips.

Boggs Lake (elevation 2,800 ft.) is actually a giant vernal pool...probably the largest vernal pool in the state. The lake surface covers about 90 acres when it is full. There are no significant streams in or out of the lake. In wet years, some water may remain all year long. The lake lies in a volcanic depression lined with a very fine covering of volcanic ash which has compacted to become impervious. The layer of ash is only a few feet thick however, and the substrata beneath it contain numerous fissures into which the water can pour when the layer of ash is penetrated. Burrowing animals occasionally breach it, causing sudden drops in water level. On one occasion, the lake level dropped 18 inches overnight. There are a half-dozen rare & endangered plants in the 1B category found there, several of which are found nowhere else in the world. Several other plants are found there that are growing well out of their range.

In 1971, a subdivision and commercial campground was proposed for the site but CNPS mounted a campaign to preserve it. The campaign caused a rare plant reserve to be established in 1973 which is now managed by the Nature Conservancy. The reserve has grown from the original donation of 101 acres to more than 200 acres today.

The history of Bogg's Lake is a fascinating one but beyond the scope of a plant list. There are good articles on the lake in the October, 1974 and the July, 1988 issues of Fremontia.

To get there, take Hwy 29 West out of Lower Lake and turn left on Bottle Rock Road, which is a considerable distance from Lower Lake. Turn left again on Harrington Flat Road. The lake will become visible on the left-hand side a short distance from the turnoff. The entrance to the reserve and a small parking area can be found on the left side of the road shortly after the lake becomes visible.

Because the lake occurs at about the 2800 ft. elevation mark, the best time to visit is from mid to late June.

This list merges several lists of plants compiled for the lake and includes plants not found on those lists but seen on our field trip on June 24, 1995. It also revises taxonomy to conform to the new Jepson Manual.

Native species are indicated by the botanical name appearing in bold type. Established alien species are indicated in normal weight type.

IRIDACEAE (Iris Family)

• Iris douglasiana (Douglas Iris)
  Note: this ID may be incorrect--Steven Ayala writes (March 1999):

  One identification on the list bothers me though - Iris douglasiana (family Iridaceae) is a maritime, coastal species...the only way it could possibly be found around Boggs Lake would be if one of the local families bought it from some nursery and planted it there.

  Two iris species are found on Harrington Flat road though: Iris macrosiphon (small, usually some shade of lavender, petals separate immediately at top of perianth tube) and Iris fernaldii (yellow, petals form a trumpet-like funnel above end of perianth tube before separating). The two interbreed freely where their ranges overlap, so the identity of a specific plant might well be Iris fernaldii X macrosiphon.
