What is an indicator plant?

An indicator plant is specifically recognized for its capacity to show signs of pest infestation. This type of plant exhibits symptoms or damage that correlates with the presence of particular pests, making it easier for pest management practitioners to identify and monitor the health of their environment. For example, if certain damage patterns are noted on the indicator plant, it can signal to the pest control professional that a specific pest issue may be present in the vicinity. This allows for targeted intervention and management strategies.

The other options do not align with the definition of an indicator plant. While some plants may be used for decoration or may be resistant to pests, these characteristics do not pertain to the role of indicating pest presence. Additionally, the characteristic of flowering annually is unrelated to pest identification or monitoring. Understanding the role of an indicator plant is crucial for effective pest management strategies in turf and ornamental settings.
