Table 2 Change in cover (cm²) for each species of lichen between 2007 and 2016 in each of the patches photographed (cm² area rounded to nearest unit), in remnants and in ASNW. Blank cells indicate lichen species was absent in both 2007 and 2016 from the sampled patches; (–) = decline in cover of lichen between 2007 and 2016; (o) = lichen species which disappear, i.e. present in 2007 and completely absent in 2016 from the sampled patches; (*) = lichens which appear, i.e. absent in 2007 and present in 2016 in the sampled patches. 1 =  patch photographed in 0.02 m² frame, 2 =  patches photographed in 0.04 m² frame
