Monitoring Wetland Invertebrates on Rhos Goch National Nature Reserve, Radnorshire (2018)
This work presents the findings of wetland invertebrate monitoring work undertaken in 2017 at Rhos Goch National Nature Reserve, Radnorshire. Previous surveys have identified the four wetland habitats of bare mud, ground layer, open water and wetland flora as key wetland invertebrate assemblage features. Previously in 2007, six monitoring stations were set up and timed searches undertaken using a range of collecting methods, with the aim of developing standardised future monitoring. Target wetland invertebrate species were then chosen for each key habitat. For the reserve to be in favourable condition for its wetland invertebrate assemblage, any monitoring would have to record at least 50% of the target taxa. This work follows on from invertebrate monitoring undertaken in 2007 and 2012. A total of 438 records of 226 invertebrate species were recorded during the current 2017 monitoring. Of the 115 target species previously recorded, only 26 species (23%) were taken in 2017, marking a steady decline over the 10 year monitoring period (68 species [59%] in 2007; 37 species [32%] in 2012). This shows that all of the four key wetland habitat features are in unfavourable condition and the percentages of the target wetland species are continuing to decline. It is recommended that the levels of grazing need to be increased to provide bare mud and open water habitat, and that scrub management should continue to keep succession in check.
