Numbers of species associated with hollows declined in an eastward direction, although this was only marginally significant. ‘Year’ was a significant variable

for all species and for all wood and bark associated species. This difference was mainly caused by there being few species present in 2004 compared to 2007. In 2004, a park (Drottningholm) was the only surveyed site, whereas in 2007 many sites in the southwestern BIBW2992 cost part of the study region were surveyed. The two measures of trunk circumference did not, in five out of the six cases, significantly explain species number. The exception was red-listed species associated with hollows, which was significant when also the variable ‘RT90N’ was included (Table 3). The number of lime trees on a site had a significantly negative relationship to all species and all wood and bark species. ANOVA failed to show any significant association (df = 24: RT90N,

P = 0.44; RT90E, P = 0.78) between the two coordinate variables and the ‘type’ of the locality (Fig. 1). Species composition Species composition was significantly affected by site ‘type’ (Fig. 4; Table 4). Both ‘Park’ and ‘Open’ were significantly correlated with species composition for all three tested groups of species. However, the north–south Aprepitant gradient had an even stronger explanatory power (Table 4). The tree circumference variables were significantly correlated with species composition in one case each (Table 4).
