Discovering Alder Trees
Our first stop in our series of field trips was the JPL Bridge. Upon the start of our observations I began to notice one particular type of tree standing out from the rest. I soon discovered that the Alder tree was very common in California. I had never seen an Alder tree before, so it triggered my interest and I started reading more about it. There are many different types of Alder trees, but the most common one we came across throughout our trips was the Alnus serrulata. Our trips were at different locations of the LA River, so I was not surprised when I found out that these trees are “native to boggy ground along streams/lakes/rivers, wetland margins, springs, spring-fed meadows, ditches and swampy fields” (Missouri Botanical Garden). I also learned that one of the benefits of the Alder tree is that it helps reduce water erosion. The Alder trees also seemed great for shade and nesting for birds and other wild life. Thus, I came to realize that these trees are immensely beneficial to the ecosystem and are a great part of its biodiversity.
