Abbott’s Lagoon Summer Wildflower Bloom Update 7/11/11

It may be approaching the middle of July but the Bay Area wildflower season is not over. Many flowers are in bloom at Abbott’s Lagoon at Pt. Reyes.

We hiked out to the lagoon, then went up to the bluff  just before the bridge and continued a short distance along the fence at the top,  and then down and over to the dunes. Except for the Gentian which was still in bud and very close, most of the summer flowers were out and blooming.  There are many species to be found and I listed all the ones that I was able to ID (with help) on the plant list below. Many birds were active today as well  but my bird list is rather small as my attention was mainly on the flowers. There were also mule deer and brush rabbits as well. It was a foggy day creating good light for wildflower photography when the winds slowed down.

ABBOTT’S LAGOON Plant list for July 11, 2011

I used the  Marin CNPS list for Abbott’s Lagoon for reference.   It  can be found at the following link: (http://www.marin.edu/cnps/ABBOTTS_LAGOON_PUBLIC_TRAIL2009.html).  I have only listed the plants I was able to identify (with much assistance) .  All errors are mine.  Includes off-trail area to North of the trail as far as edge of the freshwater lagoon, the sand-dunes and the bluffs to the S. of the bridge. This ridge to the East of, and overlooking, the brackish lagoon, is especially rich in coastal wildflowers in April and May.  List 1B plants are rare, threatened or endangered species, decimal additions are more recent clarifications of the estimated degree of rarity, 1B.1 being the rarest.    Alien species, or weeds, are marked  *.  All other plants are Californian natives.
