Cherry Orchard, Diglis

A survey looking for slow worms and habitat suitable for slow worms. Much of the site
appeared suitable for slow worms, but the population was small and seemed fragmented
(mostly restricted to the interface between grassland, scrub and bramble mosaic).

4. METHODOLOGY.

The following surveys were carried out:

  • Invertebrate surveys. Undertaken by John Meiklejohn on 18 July and 28 August 2000.
  •  Higher plant surveys. Undertaken by Ann Fells over four visits between  7 June and 25 August 2000.

4.1  INVERTEBRATES.

A brief entomological survey of the site was undertaken following accepted standard methodology
(New, 1998). Collecting methods included hand-collecting, sweep netting, tapping trees and shrubs
over a beating tray and visual observation. Standard reference texts were used to identify
invertebrates in the laboratory in cases where field identification was not possible.

The main invertebrate groups recorded were Odonata (dragonflies & damselflies), Orthoptera
(grasshoppers and crickets), Dermaptera (earwigs), Hemiptera (bugs), Hymenoptera (bees, wasps &
ants), Lepidoptera (butterflies and moths), Coleoptera (beetles), Neuroptera (lacewings), Araneae
(spiders), Opiliones (harvestmen), Crustacea (crustaceans; only woodlice recorded), Mollusca
(molluscs).

To undertake a comprehensive invertebrate survey, several visits would be required over a period
of years. Therefore the information gathered is indicative of the site, but is not entirely comprehensive.

4.2 VEGETATION.

A plant survey was undertaken following the methodology of the Phase l Habitat Survey (NCC,
1990). This involved walking over the site and mapping the different habitat types found. These
were then assessed for their plant species composition over four visits, on the 7 June, 26th June,
19 July and 25  August, to taking early and late developing species.
