A field study conducted for my IBESS class. I spent October-April looking at a marsh in Baylands Nature Preserve, Palo Alto, CA. Have a look around!

Site Overview
My site is part of a marsh located
at Baylands Nature Preserve in East Palo Alto.
It is just off to the right of the sailing dock. My area is a portion of the marsh across from
the Harriet Mundy Marsh and several feet from the sailing dock. The site is near and almost encompasses a
small rivulet of water. The rivulet is
mostly muddy with a small amount of water, which will hopefully increase once
the rainy season starts. It is just off
the gravel trail from the parking lot.
The area is approximately a rectangle of 10 by 14 meters. Its length is 10 meters while its width is 14
meters. The area of the site is 140 m2.
Where do pollinators (such as bees
and butterflies) get their food when flowers aren’t in season? How do plants adapt to extremely hot or cold
weather? How do organisms living in
streams that exist only during parts of the year survive in the summer when the
streams dry up?
My study area is littered with numerous
different species. The area is
relatively flat with a slow 1 foot incline and immediate 3 foot decline
after. The soil is mostly dry and rocky
until reaching the rivulet where it turns muddy and standing water
appears. The area contains two bushes;
both are most likely coyote bushes.
Pollinators, for example, wasps, yellow jackets, honey bees, and
butterflies, like the small green flowers on the bushes and usually exist in
abundance in areas around the plant. The
rest of the ground is littered with pickleweed.
The cactus like substance is not prickly but contains multicolored tubes
of red, yellow, and green as stalks/stems.
In addition the area contains salt grass or possibly cord grass with
brown and sometimes yellow stalks. Song
sparrows like to perch on these stalks as well as hide out in the coyote
bushes. Pygmy Blue, a small type of butterfly, like to perch on the grass and sometimes
the pickleweed but it is uncertain what they eat. Pillbugs crawl through the brush and can
occasionally be seen in openings in the grass.
Underneath a large pickleweed is an old hole in the ground. This hole might have been a home or nesting
ground for a burrowing owl or jack rabbit.
The water source is a small rivulet not quite extending into the study
area. The ground is mostly muddy with a
small puddle of water. The area’s
climate appears to be temperate and could possibly become wet in the winter
with frequent rainfall.
From Sequoia High School’s senior
parking lot, turn right onto Elwood Street.
At the stop sign turn right onto Brewster Avenue. Drive 0.6 miles on Brewster and make a left
onto Veterans Boulevard. Drive 0.3 miles
down Veterans and make the second right onto Whipple Avenue. Make a slight right to merge onto US-101 S
towards San Jose. Drive 6.8 miles on the
101 S. Take the exit to Oregon
Expressway and make a right on Embarcadero Road. After 1 mile make a left towards the Palo
Alto Airport to stay on Embarcadero.
Continue past the Duck Pond and Nature Preserve. Park in the 3rd (last) parking lot
by the sailing station. Travel along the
gravel path towards the right of the sailing station for about 20 feet to my
designated field study site (beyond the sign).
