Transcript of Sea Lettuce, Pickleweed, and Debris

Pickleweed, Sea Lettuce, and Debris
at Elkhorn Slough by Julie Guerrero, Rosa Valerio,
and Brittany Anne Hackwell Why Pickleweed and Sea Lettuce? Pickleweed and Sea Lettuce are two of the most important habitats at Elkhorn Slough. They provide a large habitat for numerous organisms throughout the slough. Pickleweed is a terrestial plant, and resides along the saltmarshes. We studied a single pickleweed habitat along the trail to Whistlestop Lagoon. Sea Lettuce, on the other hand, is an aquatic plant.
We studied a single sea lettuce habitat at Whistlestop Lagoon. Our Project Question
was: What is the difference of species richness of macroinverterbrates in Pickleweed and Sea Lettuce habitats? Our Hypothesis was:
Sea Lettuce has a higher species richness than Pickleweed Materials:
-Nets
-Small and large
-Quadrats
-Boots
-Sample Containers -Plastic Containers
-Medium and large
-Cameras
-Notebooks
-Waders
-Magnifying Glasses
-Microscopes What We Did! For the pickleweed site,
we chose four spots to sample, using the quadrats.
We gathered two samples from each spot; one of the duff, and one of the dirt. Duff is the top layer of the
dirt, including the dead branches
that fall off of the plant. For the sea lettuce site, we
placed a quadrat at two places along the shore, and took one sample from each. We placed each sample in a large plastic tub, sifted through it all, and recorded the data that we found. What We Found! The sea lettuce habitat
had a higher population
of macroinverterbrates
than the pickleweed habitat
did. On average, we found 2.6 On average, we found 2.6
macroinverterbrates in pickleweed,
and 5.33 in sea lettuce. What Else We Found! In addition to all the results, we also found a lot of trash There was a lot of debris
in the pickleweed site. The closer to
the water,
the more debris
there was. All the trash and debris
is detrimental to the
habitat, and all the organisms that live there. What We Can Do! Steps must be taken to preserve these habitats! Desposing of our waste properly is the first step. Restoration projects
that help these habitats
are a great way to help too. They help the community,
and get you involved! There are many organizations that
are dedicated to restoring
local habitats. With little steps,
we can improve not
only Elkhorn Slough, but
many habitats all around us! Acknowledgements Amy Gunzelmann Cassy Marichal Kim Swan Bree Candiloro Kenton Parker Sandra Jones Satina Ciandro Jenny de la Hoz Everyone at the
