Personal specialty project from bio 10B

From observing all the plant alongside the LA river, I found that many of them are decorating flowering plants, Magnoliopsida. Especially in the Arroyo Seco area, I found around 5 to 6 flowering plants that grow there but belong to a foreign country.
As well as along side of the LA River, we found at least more than 3 Magnoliopsida. Most of them are an invasive species that people planted in their garden and got wash away when they watering their plant. Most of them ended up in the LA River.
According to the articles, Biology, and Impacts of Pacific Island Invasive, they study a specific invasive species of Magnoliopsida. Those species according to the article Apparent competition with an invasive plant hastens the extinction of an endangered lupine, the invasive plant will complete will the native and result in the imbalance of the ecology system.
