Plants of Southern California: Fire-Followers One of the most spectacular displays of wildflowers in chaparral areas in southern California can occur in the first year after a fire. These displays are so beautiful that someone once wrote that "it is a wonder that botanists are not arsonists"! (I can't find where I read that, so if anyone knows where that is from, please let me know. I'm pretty sure it was a quote at the beginning of a section on fire followers.)
Here are two descriptions of the fire-followers:
The chaparral wildflowers that appear in luxuriant displays after fire are largely restricted to the first spring after fire. Of the more than 200 species of short-lived herbaceous plants that grow after fire, only a handful are found at any other time.
Introduction to California Chaparral, R.D. Quinn and S.C Keeley, p. 70.
Slopes that formerly supported dense and impenetrable stands of chaparral shrubs suddenly erupt in a diverse riot of color as dozens of species of annual plants burst into flower in March and early April. Under these conditions, particularly if there have been good fall and winter rains, as many as 50 to 100 or more annual species may be found flowering on a single slope.
Introduction to the Plant Life of Southern California Coast to Foothills, P.W. Rundel and R. Gustafson, p. 116.
The purpose of this page is to collect a list of fire-followers in southern California, and to categorize them. If you know of other fire followers not on this list, please let me know.
The species are divided into tables of different categories:
- Strict Fire-Followers, Appearing Only Immediately After a Fire for a Few Years
- Species that are always present, but are much more abundant after a fire
- Species that are much more visible after a fire
- Species that almost entirely bloom only Immediately After a Fire
- Species not categorized yet
Each table has a source code, decoded in a table at the end.
Important caveats:
- At least some fire followers are also disturbance followers, and may appear after a disturbance in the absence of fire, such as clearing of an area.
- At least some fire followers are also drought followers, and may appear in the next good rain year following a severe drought year. I was shocked to see four species at the Santa Rosa Plateau that I had never seen there before, in spring 2007 after the 2005-2006 drought year.
- Some chaparral fire followers are normally present in some areas all the time. Perhaps the best example of this is Phacelia distans, which appears every year with sufficient rainfall in the Borrego Desert and the nearby desert transition zone. But in the Santa Rosa Plateau it is only present after a major fire.
Cryptantha sp. and Toxicoscordion (Zigadenus) are other examples. There are many post-burn areas that are dominated by cryptantha after a fire, whereas it is a bit player the rest of the time. But there are also areas that have good displays of cryptanthas year after year. I know of two places where Toxicoscordion blooms reliably year after year as well, a location found by Lee Gordon and the meadow area below Cuyamaca Lake, both non-chaparral areas.
Ted Caragozian has also told me of similar non-fire-following behavior of some fire followers in the Ranchita area.
These caveats by no means invalidate the classification of these species as fire followers, since that is indeed how they behave the vast majority of the time in chaparral habitats.
These tables use the 1993 Jepson Manual First Edition name.
