Ecology surveys are constrained by season. The calendar below can be used as a guideline to help you to plan your project. Please note that the timings are a guideline only and circumstances (e.g. weather) can result in yearly changes. Additionally, please be aware that in many cases it is necessary to undertake more than one survey throughout the survey season. Surveys are listed alphabetically.
