Alligator Weed

The presence of this invasive species disrupts the natural flow of water due to the dense mats created from its clusters of stems. It out competes the native vegetation for space and solar energy through these dense mats because they are large cluster and limit the amount of light that submerged vegetation receives. These compact clusters of stems also disturb the regular exchange of gases that occur underneath the surface that directly influences aerobic processes, such as photosynthesis. Aside from driving down the population of native aquatic vegetation, A. philoxeroides can also influence the growth and yield of crops in pastures and fields. These dense mats can affect the natural flow of water that is used in irrigation systems and as well as affect the quality of the water by increasing the sedimentation present in the water. Both factors are things that crops depend upon to not be disturbed, to provide a healthy yield for farmers, which is also falls within an impact it has on society that will be discussed later. On top of this, the likelihood of flooding is more like due to the drainage brought upon by the dense mats, which in turn can also damage the crops. Furthermore, this is a small insight into the negative impacts this invasive species has on the environment.
