Invasive exotic plants are one of the most serious threats to natural resources in national parks. They are able to reproduce in great numbers, rapidly colonize new areas, displace native species, and alter ecosystem processes across multiple scales. Established invasive exotic plants may exist in small populations for long periods, making them difficult to detect. However, if discovered in these early stages, control efforts are likely to cost less and be more successful than after a species has become more widespread. Therefore, it is critical to detect exotic plants early and to quickly control them.
Early detection surveys for invasive plants give park managers the information they need to prioritize and plan for their control when eradication is most effective, economical, and ecologically sound. This knowledge can also help support long-term, ecosystem-wide strategies for controlling invasive plant species. Upon request by park managers, the Sonoran Desert Network may provide information on the status of invasive exotic plants in targeted areas of network parks.
