Protected Species Survey Calendar

Some ecological survey work can be limited to certain times of the year due to seasonal constraints. Certain factors, such as weather conditions, and breeding seasons mean that some surveys can only be undertaken during certain months of the year when the conditions are right.

The protected species survey calendar below highlights the optimal times of the year to survey for each species.
