What is an invasive species? Invasive species are classified as an introduced, non-native organism (plant, animal, parasite, disease, etc.) that has spread across whole ecosystems rapidly from its site of introduction. Invasive species have a high potential of causing damages to ecosystems by disrupting natural cycles. Invasive species have been known to cause harm to the environment, economy, and even to human health. There are three characteristics a species must
fall under to be considered invasive; the species must be non-native or non-indigenous to the area, adapt easily to the new ecosystem, reproduce quickly, and cause harm to property, economy, or the native plants and animals in the ecosystem.
An invasive species that has threatened Oliver's Woods is the Emerald Ash Borer (Agrilus planipennis). The Emerald Ash Borer is a type of invasive beetle that feeds on ash trees. What makes this beetle invasive is that it is a non-native species that reproduces quickly and can rapidly destroy ash trees as well as disrupt urban landscapes.
Oliver's Woods has yet to be threatened by the Emerald Ash Borer. However, as the woods is made up of many Ash trees, it is important to consider what may happen if an invasion does occur. As of recently, there have been Emerald Ash Borer traps placed in areas of Oliver's Woods that are most susceptible to damage to help combat an invasion before it can happen.
Preventative measures such as this are crucial in maintaining the health of the woods.
