Surveys

Great crested newts have a very limited survey season. Presence/absence and population surveys can only be undertaken when newts are in the ponds for breeding, which is usually between mid-March and mid-June. At least half the surveys must be undertaken between mid-April and mid-May. Surveys comprise between 4 and 6 survey visits, and torch searches, bottle trapping and egg searches are usually required. Habitat assessments can be undertaken all year round.

While some invertebrates are generalists, and feed on or live in a wide variety of trees, many can only be found on certain species, or a very small number of species. Sometimes the name is a dead giveaway – oak apple gall wasps, the blue willow beetle etc. But some can be somewhat inaccurate – for instance the oak eggar moth does not feed on oaks, but gets its name due to the cocoon resembling an acorn.
