Why should we care?
Once here, invasive species can easily spread and outcompete native flora and fauna, upsetting the natural balance. This can lead to many detrimental environmental changes, such as losses of habitat quality or quantity, changes to ecosystem processes, declines or losses of other native or beneficial species or other environmental changes.
Invasive species also cost our economy billions of dollars per year by lowering productivity and yields of natural resource-based industries, damaging infrastructure, hampering trade, and costing money to control and monitor. Human wellbeing is also affected by invasive species as they can impact our recreational areas and opportunities, damage our cultural resources and restrict our way of life. Some invasive species even pose a direct threat to human health.
