Nature's Calendar

Find out the best times of year to see and survey particular species.

What’s about and when?

At different times of the year, different things are happening in the lifecycles of our wildlife. This means that certain times of year are better for seeing and surveying species. For example, great crested newts hibernate between December and March, so there is little point in surveying for them during that time.

And some species are also more sensitive to disturbance at certain times of year, for example when they are rearing young.

Our Nature's calendar shows the best times to survey certain species and the times that species are most sensitive during their annual lifecycles.
