Survey calendar

Protected species surveys often have seasonal restrictions, which can affect the timing of planning applications. To help you plan ahead, we have created a simple survey calendar that shows the optimal months for all key ecological surveys.

Why survey windows matter

Different species can only be surveyed at certain times of year. Planning authorities must ensure that surveys are valid, and cannot determine applications that rely on out-of-season data.

Understanding survey windows helps you:

• Plan your project timetable more confidently

• Avoid predictable delays

• Ensure your application is supported by valid evidence

• Identify the most efficient route through planning

Need help interpreting the calendar?

We regularly help homeowners, architects and developers to integrate survey windows into project timelines.

If you would like guidance, send us your drawings or a short description of your site and we will recommend the most efficient route forward.
