Plant Species List for the SRP

• Brodiaea santarosae, The Santa Rosa Basalt Brodiaea (not yet added to the lists below)

• Flora of the Trails of the Santa Rosa Plateau Ecological Reserve (the latest list of the 456 taxa that occur on or near the trails of the Santa Rosa Plateau Ecological Reserve (updated 7 April 2006 for list as of 7 September 2005).

• Analysis of Flora of the Trails of the Santa Rosa Plateau Ecological Reserve (analysis of the latest list of the 456 taxa (36 taxa added since 9 June 2005!) that occur on or near the trails of the Santa Rosa Plateau Ecological Reserve as of 7 September 2005; analysis page updated 8 September 2005).

• Taxa of the Santa Rosa Plateau Ecological Reserve Found Only Off-Trail (the latest list of the 188 taxa that occur only off-trail within the Santa Rosa Plateau Ecological Reserve; updated 9 June 2005; note that some of these taxa were subsequently found on trail later in 2005).

• Flora of the Greater Santa Rosa Plateau Region (the latest list of the 667 taxa that occur in the entire greater Santa Rosa Plateau Region; updated 9 June 2005).

  Subsets of this Flora, with additional information such as bloom times, life form, and number of trails on which each taxa was observed, both at the SRP and elsewhere in Southern California (these lists are not current; they were last updated in 2003):

  • The Most Common Showy Flowers, Shrubs and Trees (the 109 most common noticeable flowers, shrubs and trees found on the trails of the Santa Rosa Plateau Ecological Reserve, sorted by the number of trails for which each taxon has been found)
  • Common Showy Flowers, Shrubs and Trees (the 195 most common noticeable flowers, shrubs and trees found on the trails of the Santa Rosa Plateau Ecological Reserve, in conventional family order)
  • List of Taxa That Are Not Common Showy Flowers, Shrubs and Trees (the rest of the entire plant list, in conventional family order)

• Bloom Identification Guide (Strong and Chester's guide to identifying plants on the trails of the SRP by flower color and plant habit; 148 sp.)

• Gordon House's Historical Record of Plants Blooming in the Santa Rosa Plateau (The total list of species recorded by Gordon House for 1997-2000 in his Bloom Reports; 126 species. A few misidentifications still need to be corrected; compare to the SRP species list above to make sure any species here is on the list.)

• Additions To The Plant List For The Santa Rosa Plateau (The ten additional species I found in 2001 and 2002. Note that this is an older page; many more species have been added in 2003, which are given in the latest list above.)
