Chapters 13 establish the need for early-detection of invasive plants, provide linkages to relevant policies and programs, summarize dominant invasion theories relevant to this text, and outline the key components required to implement a successful early-detection monitoring program. Chapters 410 address each of the early-detection steps in detail including setting goals and objectives, prioritizing species and resources for monitoring, identifying remote sensing options, choosing analytical processes, conducting evaluation and assessment, formulating sampling design, managing data, and implementing detection methods. Chapters 1113 provide examples of applications of early-detection principles, including: insights into early-detection protocol development across multiple parks, an approach to probabilistic predictive modeling of invasive plants with detailed examples, an example using remotely sensed and geographically referenced data for predicting the risk of occurrence for target species, a small park example using volunteers, and a protocol for integrating early-detection and long-term trends monitoring across large and small parks. Subsequent materials include citations, a glossary, detailed reports from participating researchers, and a protocol template that meets NPS I&M program standards. The protocol template will be useful for those who may be required to document their specific early-detection procedures.
