It’s officially spring!
As the days get longer and the weather warms up, wildlife is becoming active again and the survey season is already in full swing. Reptiles are emerging from hibernation and basking in the sunshine, while Great Crested Newts (GCN) are gathering in their ponds for breeding. There’s still time to arrange surveys, but where GCN population size estimates are needed, Natural England requires 2-3 visits before mid-May, so it’s worth booking soon.
This is also the perfect time to start looking at terrestrial invertebrates, as valuable assemblages can appear across a variety of habitats. Where proposals affect streams or watercourses, it’s worth checking for White-Clawed Crayfish.
Bats are becoming active too, with activity surveys possible from April and emergence surveys of potential roosts beginning in early May. This is typically a very busy survey month, so contact your ecologist now to discuss your requirements.
The breeding bird season is well underway, but surveys can still be carried out in woodland, farmland, hedgerows, coastal habitats and heathlands. Spring is also the ideal time to plan botanical surveys, particularly in woodlands and acid grasslands, before the optimal window closes at about the end of May.
