GRASSLAND SURVEY 2020
Here are the results of a baseline survey of invertebrate life commissioned by the WoodChips and carried out during the summer of 2020 by Graeme Lyons, an ecologist who specialises in invertebrates.
Graeme surveyed mostly on the grassland areas to discover what invertebrate species are present at the site. He used various methods, including a vacuum, a sweep net and beating tray, to discover what is crawling, climbing and flying at the site. This will enable future generations of naturalists and ecologists to study changes to the invertebrate fauna and will, I'm sure, enhance our knowledge of the importance of the semi-natural grasslands in our stewardship.
One thing is immediately obvious from this baseline survey – the relatively high proportion of species currently regarded to be of national conservation concern. When viewing the data, please be aware that the number 1 indicates presence at the site – it is NOT a count of specimens collected!
I have, where possible, added the English (Vernacular) names to aid those who are not used to using the scientific names of species.

The following abbreviations are used to indicate conservation status:
NR = Nationally Rare
NS = Nationally Scarce
NT = Near Threatened
VU = Vulnerable
EN = Endangered
LC = Least Concern (but illegal to collect, injure, or kill under Schedule 5 of the Wildlife Act in the UK.)
The 7.8% rating for species conservation status gives us a snapshot of the Conservation Value of the Site – 7.8% of all species found are in need of conservation measures and/or monitoring.
