Introduction Flora of the Santa Rosa Plateau 2010 Burn Area
The FloraIntroduction
This flora is the result of two surveys of the 60 acre burn area at the Santa Rosa Plateau from the fire that began at the Visitor Center and burned north on 1 September 2010. The first survey was done on 25 April 2011, by Tom Chester, Dave Stith, and Kay Madore, with Marsha Hanson and Jeanne Gulley participating in the first part of the survey. The second survey was done on 29 April 2011 by Tom Chester, Mike Crouse and Michael Charters. Michael put some of his images from this trip in his photogallery.
We intend to keep surveying this area this year, and in subsequent years, to record the species as a function of year after the burn.
In the future, we'll add an analysis of this list, since we have a pre-burn checklist for the part of the burn area covered by the Granite Loop and Wiashal Trails.
Several new records for the SRP Flora resulted from these surveys. More on those will be added in the future.
The Flora
The Flora
The Checklist below contains only species that are fairly confidently identified, although some identifications are only from young plants. Thus a few identifications may turn out to be incorrect.
One notable species is missing from the list, since we are not sure of its determination yet. There are about 30 plants scattered over three locations of a young plant that looks like a baby Malacothamnus or Ribes. The hairs of those plants are similar to those of Ribes, but no Ribes species was found in this area before the burn.
For pictures of some of these species, see photogallery from Michael Charters from 29 April 2011.
The Checklist is sorted first by category - dicots, monocots, and ferns - and then by family and scientific name. The Family and Scientific Name are from the 1993 first edition Jepson Manual. An asterisk before the Common Name indicates a non-native taxon.
Estimates of the minimum number of plants, up to a maximum of 99 plants, are given in each of the two survey areas, the Wiashal burn area and the Granite Loop burn area. For the Wiashal burn area, the number of locations is also given, up to a maximum of 9. A "location" is not precisely-defined, but is roughly an area of radius 0.1 mile.
