In this episode of K9 Conservationists, Kayla speaks with Dr. Charles van Rees, our Conservation Correspondent, about invasive species. Science Highlight: None What makes a species invasive? Generalists Fast-reproducing Behavioral flexibility Lack predators/pressures Harmful to the ecosystem in general Why do they matter? Conservation implications Economic losses (statistics) How do they work? Arrival Propagules Establishment Secondary spread How do people deal with them? EDRR & related surveying Tier system from PRISM Tier 1 – Early Detection/Prevention – Highest level of survey efforts. Should conduct delineation surveys and assign to appropriate Tier if detected. (a) inside buffer but not in PRISM, (b) outside PRISM and buffer, but close (eastern North America), (c) Far outside PRISM and buffer (not in east NA) but introduction pathway exists. Tier 2 – Eradication – Highest level of response efforts. High impact species with low enough abundance to make era
