The module will help you to choose the most suitable methods for your situation. It's important to use monitoring methods in a consistent way and to the same standards. This will give you confidence in what the monitoring data is saying and help inform decisions.
How to use this module
- Read our Introduction to animal pest monitoring. In this document you will find comparative tables and decision trees to help you select the methods that are best for your study.
- Once you have selected the best methods, read the method descriptions to inventory and monitor animal pests. Be sure to take note of the minimum data collection standards for methods.
- Prepare your project.
- Read project planning guides to help with planning.
- Check if any online DOC training courses for your chosen method.
Introduction to animal pest monitoring
This document introduces the different methods to inventory and monitor animal pest populations.
Tables and decision trees will help you to decide on the methods appropriate for your project’s objectives. Some comparative tables and decision trees are specific to determining the most suitable methods for goat and deer monitoring.
