Cherry Orchard, Diglis
The rough vegetation along the boundary with Diglis Lane and trees near the north and west
boundaries give some cover for a limited range of invertebrates. A small colony of gatekeeper
butterﬂies (Pyronia tithonus) use the grass on the edge of the recreation ground opposite the sharp
bend in Navigation Road (indicated by ‘Pt’ on map 7.1).
Rough grass and scrub area
The time of year when this survey was carried out was too late for many beetle species but a large number of many of the common grassland bug species were found. A range of common species, including eight members of the ladybird family, were found in good numbers. Only two of the common species of orthoptera were found, both frequently. No nationally listed or RDB species
were recorded but the five specimens of Notoxus found in the sandy area at SO849l53l5 were of special interest. These bare sand areas should be conserved as possible nesting sites for various hymenoptera – solitary bees and hunting wasps. The osiers in the same area were rich in beetles,again common species.
River bank area
A few species of common invertebrates was found associated with the vegetation between the river and the berm. As expected in the shaded conditions, numerous spiders, harvestmen and snails were found.
There are no permanent water bodies on the site, although there is evidence of seasonal ponds in the southern section of the site adjacent to the Duck Brook, but these were dry at the time of the invertebrate survey. No sampling was carried out in the river as access is difficult and dangerous.
There are, therefore, no records for water invertebrates from this survey.
A list of invertebrate species recorded on the site is given in Appendix 8.1.
The site comprises two clearly distinct areas — an intensively managed recreation ground (the north end) and a largely un-managed area (the south end). The latter of these comprises a large central area of rough grassland fairly free of scrub, surrounded by dense bramble thickets, grassland with
abundant scrub invasion and tall ruderal vegetation. The greatest species diversity is in the rough grassland. These areas are described in greater detail below.
