Invertebrates of Trees and Shrubs


Description

Clearly very common, but different species of tree support different invertebrates and different ages of those trees support increasingly specialised invertebrates. Some species require a combination of habitats e.g. hawthorn and umbellifers.

Fauna: e.g. forest bug

A common shield bug found throughout most of Britain. A tree-dwelling predator of caterpillars etc, most often found in woods but also recorded on isolated trees.

Forest bug (Pentatoma rufipes)

Importance

Many invertebrate species of trees and shrubs perform vital tasks such as predation of pest species (such as aphids) and pollination. They also have an important position in the food chain, supporting local populations of small mammals, birds, etc.

Beneficial management

  • All native trees have considerable wildlife value. Maintain all native trees around the farm.
  • Aim to maintain or establish the full age range, from new saplings to mature standards through to veterans.
  • Avoid fertiliser and pesticide drift near hedgerow or in-field trees and shrubs.
  • Avoid soil disturbance close to trees, try to leave at least the width of the canopy undisturbed.
  • Avoid over-tidiness by leaving dead wood in-situ unless it poses a direct safety concern e.g. adjacent to roads and footpaths.
