- Many exotic plant pests and pathogens are unknown prior to their establishment, making prevention and management difficult.
- Sentinel plantings to detect pests and pathogens prior to introduction provide information about the likelihood of introduction and the potential impact on plants native to the importing country.
- This paper discusses the different types of sentinel plantings based on the native range and age of the plants, their purpose, limitations and benefits.
- Summarised results from published studies illustrate the benefits of sentinel plantings
