Pinkham Way: Report on the continuation of the invertebrate survey from end of February to the end of September 2015. By Edward Milner 1. Results The trapping described in the Preliminary Report was continued from the end of February 2015 until the end of September 2015. A further 11 (possibly 12) species of spider were added, making a current list of 86 spp. A total of 14 new species of beetle were recorded, and all the beetle records (79 spp.) from the earlier (Ove Arup) survey were added to the database. In total this resulted in a list of 243 spp. of beetle recorded from the site. Lists of the two groups are included below in the Appendices. In the Preliminary Report it was suggested that it might take five years trapping (plus sweepnetting, which has not been permitted) to reach 100 spp. of spider but this limited extension has shown that such a list might be produced much sooner than that. Beetles Of the newly recorded species (in heavy type in the species list)most were common and widespread in the London area. The only one of note was Kissophagus hederae(Scolytidae)Nationally Notable B, a scarce bark beetle which is known to visit ivy flowers for nectar. It is scarce in the London area. Among the beetles recorded during the Ove Arup survey 12 were species not recorded by the author at other sites in the London area, and at least 10 further species appear to be scarce in the whole London area; the conclusion that should have been drawn was that in the London context this is an unusually rich site for beetles. Spiders The newly recorded spiders (in heavy type in the list) are all fairly common species mostly known from at least 20 sites in London and Middlesex. Pseudoscorpion During the Ove Arup survey a pseudoscorpion Chthonius tetrachelatus was recorded. This is a scarce species only known from two other sites in north London. Conclusion and recommendations The newly recorded species do not throw additional light on the conservation value of the site except to confirm the earlier conclusion that the site is of considerable conservation value both in the local context within Haringey, and in the wider London context. 1 It is strongly recommended that the site be protected, and that the invasive alien plants in particular Russian Comfrey and Goat’s Rue be removed from the site as far as possible. Current stewardship by the North London Waste Authority does not appear to be addressing this issue. At a future date further pitfall-trapping and, ideally, regular summer sweepnetting should be done across the site, including the south-facing railway bank. It must be assumed that there are numerous species of beetle and spider (and possibly pseudoscorpion) present on the site that are yet to be recorded. JEDM 5/10/2015 2 2. Appendices Appendix 1. List of all beetles recorded First column is National Conservation status (if any), followed by name of beetle, date of first record and the author’s reference No. Main plant-feeding families are Elateridae (click beetles), Apionidae (tiny weevils), Chrysomelidae (flower beetles) and Curculionidae (weevils) Reference No. 000301 refers to beetles first recorded in the Ove Arup survey Species
