Some of the ecological problems of the stream at Stafford Lake are the invasive plant species that are trying to take over the grassy area, and other native species, by the stream. The plants are taking all the nutrients from the native plants so they can't grow and flourish as much as they should be able to. The Marin County Parks Project has also been doing other things to take control over the erosion happening to the stream. To control the speed of the water, they created the stream to move like a snake.They also bring out volunteer groups to help get rid of invasive plants. The part of the park we worked on yesterday was sheet mulching by the stream bed. We laid down a layer of hay, then 2 layers of cardboard to keep the plants from growing through the hay, another layer of hay, and then mulch on top. Yes, I think so because what we were working on was a method to try and keep the invasive species from growing by adding many layers over the soil so the couldn't grow through. This works with pest management because we are making a way to manage the growth of the unwanted invasive plants along the stream, so that the native plants will be able to grow and get the nutrients they need from the water. What I liked was being out in nature with my friends and working on protecting a place close to home that I enjoy visiting. Also, I thought that it was a great to show students how much we can impact and help the community. Also that by us sheet mulching, we were helping create better drinking water quality for others and ourselves.
