Countryside Survey, Topsoil Invertebrates – Number of Broad Taxa

Countryside Survey topsoil Number of Invertebrate Broad Taxa data is representative of 0 – 8 cm soil depth. For invertebrate data, a total of 947 cores from 256 1km × 1km squares across Great Britain were analysed in 2007. Please see Emmett et al. 2010 for further details of sampling and methods.

Estimates of mean values within selected habitats and parent material characteristics across GB were made using CS data from 1998 and 2007 using a mixed model approach. Please see Scott, 2008 for further details of similar statistical analysis.

The estimated means of combinations of broad habitat/dominant grain size class using 2007 data are mapped on to the dominant habitat and dominant grain size class in each 1km × 1km square 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. 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. Where these areas occur they are left blank.
