Invasive species (exotic or non-native species) can be animals or plants that establish themselves in an area where they are not naturally from. The non-native species are often a nuisance to the area’s natural habitat. Not only can they cause an imbalance in an ecosystem, they can also wreak havoc on the lives of humans by creating obstacles for local manufacturing and trade. Unfortunately, these invasive species thrive since they don’t have competition, which also allows them to spread quickly. More than 140 non-native species have been introduced to the Great Lakes since the 19th century. It’s predicted that 34% of these invasive species find their way into the Great Lakes via ballast water.
Once the invasive species are introduced, it’s challenging to find a safe way to remove them, which is why prevention is key. If you are an avid lake goer, there are simple ways to decrease the spread of invasive species.
1. Inspect and clean everything that has had contact with the water-even your dog. This also includes boats, jet skis, trailers, boots, tires, etc. Some plants and animals from the lake can be microscopic and are able to survive in a small amount of mud or water. Use towels to dry out motors, scuba tanks, flotation devices, etc. Hot water, vinegar or salt water can be used to properly clean boating items.
2. Do not release any plants or animals into water that they did not come from. You don’t want to put bait or an aquatic pet into a body of water if it doesn’t belong in that body of water. Storm drains should not be used for disposal either, because they sometimes connect to lakes or wetlands.
3. Spread the word to other lake goers. If you have extra towels or cleaning products, share them with fellow boaters. Some boaters might not be aware of the situation, so you can explain to them why it’s important for them to sterilize their equipment before leaving the lake.
Although legislation plays an important role in battling the spread of invasive species, individuals need to lend a helping hand. Eradicating non-native species is difficult without killing off the rest of the ecosystem, so it’s crucial to focus on prevention so additional organisms don’t make their way in.
