SNH Invertebrate Site Condition Monitoring 2013/14: Alvie SSSI

Quality Control

We have a very high level of confidence in this dataset. Where necessary, rare specimens were compared against reference collections, those held in the National Museums Scotland collection and identities confirmed with experts.

Method steps

1. Surveys targeted the invertebrate assemblage feature of Alvie SSSI. However, other taxa were also recorded. We sampled adult Diptera on 15 April 2013 by sweep netting along a transect attempting to cover a representative area of deadwood habitats around Tor Alvie. One sweep consisted of moving the net back and forth through the vegetation ahead whilst walking slowly, covering approximately a 10 x 1 m section of ground. We surveyed for Donacia aquatica by sweeping emergent and bankside vegetation on 1 July 2013. We sampled Vertigo lilljeborgi on 6 July 2013 by taking 1L samples from the edge of Loch Beag. Hagenella clathrata was sampled using sweep nets around the bankside vegetation of Bogach on 15 and 16 July 2013.
