How do you manage invasives at water intakes?
Invasive plants and animals can disrupt any natural water system if they are allowed to do so. If left without controls at water intakes, they can take over the local habitat that create negative impacts in a variety of different ways. There are three points of emphasis which are used to stop invasives from taking over: disease control, early detection, and reactive response.
Disease control maintains the local plant and animal populations. A habitat that is fighting a disease is a habitat that is vulnerable to invasives. Through monitoring efforts, diseases are either treated immediately or removed from the local habitat.
Early detection creates a faster response. The goal of an early detection campaign is to make sure that invasives have the lowest possible impact on the local environment.
Reactive responses reduce or remove a threat. This can be done through manual removal, decontamination, or through biological controls. The latter option allows for other living plants or animals to be introduced into the water intakes so that the invasives are eliminated over time.
If invasives do gain control over a habitat, it becomes almost impossible to have them removed. This is why prevention is always the first and most important goal in protecting local water intakes. Our natural habitats are precious. Procedures like these will make sure they are preserved for generations to come.
