Significant values are given in bold
Species responses to land use are assigned as winner, loser or mid-specialist to the following land-use parameters forest management index (FORMI), the percentage of non-native trees (Inonat), the percentage of dead wood with saw cuts (Idwcut) and the percentage of tree harvesting (Iharv)
“Low” and “high” refer to low- and high-gradient species, respectively. Red List status: * = no current risk (least concern), G = endangered to unknown extent, R = very rare, V = near threatened, 1 = critically endangered, 2 = endangered, 3 = vulnerable
