Model estimates of topsoil invertebrates [Countryside Survey]

Countryside Survey topsoil invertebrate data is representative of 0 - 8 cm soil depth and includes Total catch, Mite:Springtail ratio, Number of broad taxa and Shannon diversity. For invertebrate data, a total of 947 cores from 256 1km x 1km squares across Great Britain were analysed in 2007. Please see Emmett et al. 2010 for further details of sampling and methods (http://www.countrysidesurvey.org.uk/outputs/technical-reports). Estimates of mean values within selected habitats and parent material characteristics across GB were made using CS data from 1978, 1998 and 2007 using a mixed model approach. Please see Scott, 2008 for further details of similar statistical analysis (http://www.countrysidesurvey.org.uk/outputs/technical-reports). The estimated means of habitat /parent material combinations using 2007 data are modelled on dominant habitat and parent material characteristics derived from the Land Cover Map 2007 and Parent Material Model 2009, respectively. The parent material characteristic used was that which minimised AIC in each model (see Supporting Information). Areas, such as urban and littoral rock, are not sampled by CS and therefore have no associated data. Also, in some circumstances sample sizes for particular habitat / parent material combinations were insufficient to estimate mean values.
