The vascular plant list is the product of many people's efforts extending from well before the Elfin Forest officially came into existance as a natural area preserve. The list that this table superceeds dates from 2005 - the publication date of SWAP's "Plants and Animals of the Elfin Forest Natural Area - A Pocket Guide".

Recently, Dr. David J. Keil, Curator of the Robert F. Hoover Herbarium at CalPoly, spent considerable time and effort in the Elfin Forest to confirm and update the list. Dr. Keil was able to confirm 138 of the species as being present. 12 were removed from the list as being confirmed "not present" - previous misidentifications, extripated by nature or by the Weed Warriors. 22 new plants were added (of these 6 replace plants that were most likely misidentified previously which will probably be removed from the list). Dr. Keil notes that 23 of the oiginal scientific names have changed in the intervening 10 years.

Over the next several cycle of seasons the SWAP volunteers will be working to establish the presence or absence of the plants that Dr. Keil was not able to confirm - 82 individual species. We have located 8 so far - only 74 more to go. Expect to see this list updated frequently.

Thank you, David!

 





 

ID – arbitrary number used to cross reference between a plant’s scientific and common name(s) in the companion table available which will available soon.

Scientific Name – Authoritive name in the order Genus + species, occasionally followed by var. (varitity) or ssp. (subspieces). Clicking on the scientific name will bring up Calflora's listing for that plant; see "Calflora" below.

  ● = non-native species
●● = non-native species which is or has the potential to negatively impact the native species of the Elfin Forest.

Common Name – A vernacular name for a species often used in local area. Most plants are known by multiple common names.

Form
       T = tree
       S = shrub
       H = herb
       Sh = short herb – under 6”
       V = vine
       G = grass
       Gc = ground cover.

(Some plants have more than one form within the Forest because of local environmental conditions.)

Bloom – the months in which a plant “normally” blooms. Weather can changes these dates. Some plants bloom nearly all year round in the Forest’s mild climate,  for them “Bloom” = peak period


 KEY



Habit(at)
– refers to plant association or complex:
     c = maritime chaparral
     d = disturbed (open sand)
     k = brackish water marsh
     m = coastal salt marsh – vegetated
     o = coast live oak woodland
     r = riparian
     s = coastal dune scrub
     u = mud flat – unvegitated tidal lands and channels
     z = oak/manzanita complex

Color –
predominant color(s) of blooms.
       W = white
       Y = yellow
       O = orange
       R = red
       P = pink
       B = blue
       L = lavender or purple
       C = cream
       I = indistinct.

Where bloom has a definite two colored pattern, it is shown like “WY” – white outside/yellow center, etc.

Photo –
if ais shown clicking on it will bring up photographs of the plant from UC Berkeley's CalPhotos Image Collection - www.calphotos.org. You may freely look through their collection of photographs, but, if you want to make any other use of the photos be sure and respect the copyrights and restrictions found with each individual photograph. All this is explained on the CalPhoto web site.

Cfm –
"Confirmed" means the presence of the species has been confirmed since the 2005 list. "K13" indicates Dr. Keil found the plant present in 2013; "N15" = Al Normandin 2015, "M14" indicates Bob Meyer 2014, and "Y16" indicates Yolanda Waddell 2016. More plant IDers to be added.
