The Marsh Field Study


Site Overview:


The location that I chose is a marsh near the Travelodge that is right near highway 101. I chose this area because this area is right near where I live. I also chose this spot because it is right near a highway and it has a sewer pipe leading into it so it has a lot of pollution and I want to study how polluted it is. My area I think might have some air pollution in it because it is right near the highway and I know it has a lot of water pollution in it because I have seen trash thrown into it and there is a sewer pipe leading into it. Driving directions from Tam High School are the following: 1.Start out going northwest on Miller Avenue toward Camino Alto. 2.Turn right onto Camino Alto. 3.Turn right onto E Blithedale ave. 4.Merge onto US‑101 S toward San Francisco. 5.Take the first exit. 6.Stay Straight and you will see the marsh on your right side. Below is an aerial view of the marsh:


The History: The main historical thing about this area is that before white people started to settle down here the Miwok Indians used to live here. But when the white men started to settle down here they moved further up north to escape the "white man." Then a little while after that Shelter hill Apartments were built along the marsh. You can see the apartment complex to the left of the marsh in this image.


Impacts:


Some of the human impacts that I have seen around my area were that there has been a Travelodge built right next to the marsh. Another impact that I have observed is that. There is a highway built right next to it. The high way probably causes air pollution because of the gases that cars release constantly from the exhaust pipe when they are running on the freeway. I also think that there is a lot of water pollution because of the sewer pipe that leads all of its wastes right into the marsh. And you can also see the pollution on the image that is given above. Another cause of water pollution is that you can just see trash thrown into the marsh. The water for this marsh comes from Richard son Bay which is not shown on the image. I think that these human impacts that are harming the marsh could be reduced greatly. The only thing that you could probably reduce is the water pollution by protecting the area more and having fines for people who are caught littering into the marsh. You could reduce the air pollution but you would have to tear down the highway or you would have to somehow reroute the highway or block this part of the highway off.


Habitat Ecology:


My Ecosystem is a coastal wetland ecosystem. This marsh is a modified ecosystem because it has been altered by humans but it has not been altered by agriculture. No cultivation has been taken place. Three of the biggest human activities that have changed this ecosystem are water pollution, air pollution, and urbanization and suburban sprawl. The air is polluted because of the nearby highway. The water has been polluted because of the sewer pipe and people throwing trash into it. Urbanization and suburban sprawls have changed the ecosystem because apartment buildings, hotels, and a highway have been built right near it.


Day one: I am seeing a low tide today and there isnít much going on except for a couple of birds that flew by. I know that I saw a blue Heron that flew into the marsh and just stood there and looked around. After a while it flew away. I also saw some crows flying by but the just swooped down and looked around and flew off they didnít even land. After a little while I went looking for some insects but I had a hard time finding some. I know I saw two Dragonflies flying against the wind. They kept on flying against the wind, and every few seconds they would drift back to where they started and then once again they would fly a little farther than before but then they would go back to where
