Invasive species may be impacting your backyard without you even realizing it. These non-native plants, animals, and organisms can harm ecosystems, the economy, and even human health when they take root in areas where they don’t naturally belong.
If you missed our recent Facebook Live presentation on this important topic, don’t worry — the recording is now available for on-demand viewing! In the webinar, experts from the Princeton Hydro team – Michael McGraw, CSE, QAWB, ACE, Senior Project Manager and Senior Wildlife Biologist of Regulatory Compliance & Wildlife Surveys, and Jesse Smith, Aquatic Ecologist – provide practical tips on how to identify and manage invasive species, helping to keep your backyard and local environment thriving.
Invasive species are organisms that are not native to an area but thrive and spread aggressively, often causing harm to native ecosystems. They compete for resources, disrupt habitats, and can introduce diseases, leading to the decline of native species. Unlike exotic species, which may be non-native but do not necessarily cause harm, invasive species tend to simplify ecosystems by outcompeting native plants and animals.
A well-known example is the Emerald Ash Borer, a beetle responsible for the widespread death of ash trees across North America. Another, Phragmites australis, also known as Common Reed, is a highly invasive grass that dominates wetlands, lowering biodiversity and displacing native species. The spread of these and other invasive species can be exacerbated by human activity and even by climate change.
In their natural environment, invasive species have predators and environmental checks that keep their populations under control. However, when introduced to new habitats, they lack these natural controls, allowing them to spread rapidly. Invasive species can alter ecosystems by:
Freshwater ecosystems and wetlands are particularly vulnerable because it’s hard to contain the spread of invasives in these environments. Once established, invasive species are difficult to remove and can cause long-term damage.
The good news is that there are steps we can take to help prevent and manage invasive species in our communities. Here’s what you can do:
Educate and Share: Education is one of the most powerful tools in fighting invasives. Learn about which plants are native and beneficial to your specific region. Talk with your neighbors, community organizations, and local land managers about the importance of managing invasive species. And consider sharing educational resources like this blog and our on-demand webinar.
Reduce the Spread: Prevention is the best strategy. By planting native species, removing invasives, and avoiding the release of invasive species into the environment, you can help stop the spread.
Monitor Your Property: Routinely checking your property for invasive species is key to early detection. Reach out to local watershed organizations to get involved in monitoring efforts. Get involved with organizations focused on monitoring and protecting local lakes and waterways. In Virginia, the Smith Mountain Lake Association has launched “Dock Watch,” a community science program where volunteers collect water samples from select docks to monitor harmful algal blooms, track cyanobacteria levels, and report invasive aquatic species.
Document and Report: Learn to identify common invasive species in your area and report them to local authorities, such as your county extension office or an invasive species management team. In New Jersey, the Invasive Species Strike Team works to control the spread of these harmful organisms.
Here are some methods to consider when removing Invasive Species:
