Lab # 4
Marmot Dam
First of all, Being outdoors
exploring the nature is something that you won’t never forget . I visited the Marmot Dam and it was one of the most
experience that I have ever had . We met a couple of people and there was a
guy with a girl. He told us that the Dam was built in 1913 and destroyed in 2007, since that day the Dam
started to be history. Where the Dam was built there were some buildings that
were used for power facility that were destroyed as well. An organization
called Western
Beaver Conservancy started to
work in planting seeds and do some restoration project. There are some invasive
plants such as: Scotch Broom and brinca that need to be pulled out before
restoring. Also some people did some experiments for knowing what kind of
plants can survive, and some trees have four years that have been planted. We
were informed that Sandy River has 4 species of fish which are: Chinook,
Salmon, Trout, Spring.
Some of us were close where the Dam was built. A study has shown that a million cubic yard of sediments was found in the river. Spooning is upstream lahars, Always there are sediments on the sandy river, people have measured it how much sediment is inside of it, so this process last 3 to 5 years. When I started to cross the bridge I walked very close where the Dam was located. The bridge has been there since the Dam was built. The place where the Dam was located is surrounded by tall trees such as: Douglas fir, western hemlock, and also shrubs like vine maple, then I went inside of the forest and I saw a lot of woody debris, sword ferns, and a lot of trees with moss and lichen as well.
There was a tree fallen with a
diversity of woody debris. The soil surface inside the forest was covered by
decomposing material such as: needles from trees that have fallen off and logs as well, and the
trees that I saw were filled with a variety of moss. Shadia Duery told us
that when there are trees with 1 meter tall and there are others that are
smaller can’t grow because all of them are fighting for obtaining sunlight.
A girl that gave us the tour told
us that there is a fern called licorice
fern which grows on the upper parts of the trees, and it is a different species.
Some of us tasted it and was very sweet like sugar cane. Also the gravel that is along the bottom was formed after the
Dam was removed. To me hear about the Dam is something that amazed me, and as I
wrote I have learn many things about it.

Douglas. Good job on your Lab 4. Nice work adding three pictures and a video to illustrate the location of the field trip. Your grade is 8.5/10. You missed 1.5 points because you did not use enough references to the ecology of the place. Keep up the good work!
