Many ecological surveys can only be undertaken during specific times of the year, and some require multiple visits across a limited seasonal window.

To help developers, planners, architects and landowners plan ahead, we’ve produced a downloadable Ecology Survey Calendar covering the most common protected species and habitat surveys in England, including:

• Bats
• Great Crested Newts
• Breeding Birds
• Dormice
• Reptiles
• Water Voles
• Otters
• UKHab Surveys
• …and more.

The Ecology Survey Calendar provides a quick visual overview of:

✅ Optimal survey timings
✅ Sub-optimal survey timings
✅ Seasonal constraints that could affect planning timelines

 

Early ecological input can significantly reduce programme risk and help avoid unnecessary delays later in the planning process.
