Table 1 Roost tree-scale characteristics of 22 roost trees used by Myotis californicus. Contextual variables included the following: bat frequency: individual identifier; tree species: ALRH = White alder (Alnus rhombifolia), CADE = Incense cedars (Calocedrus spp.), QUKE = California black oak (Quercus kelloggii), UMCA = California bay (Umbellularia californica), QUCH = Canyon live oak (Quercus chyrysolepis), ABCO = White fir (Abies concolor); roost type: CR = crevice, EB = exfoliating bark, CA = cavity, UK = unknown; roost height: vertical height of roost on tree (m). Environmental variables used in the analysis included the following: DBH: diameter at breast height (cm); tree height (m); % Exfol. bark: estimated percentage of bark on tree that is exfoliating; % Bark on tree: estimated percentage of tree that is covered in bark; % Canopy cover; Snags: number of snags within 17.8 m of roost tree; Sun exposure: 1 = none, 2 = half, 3 = full; Crown class: D = dominant, C = co-dominant, I = intermediate, S = suppressed; Leaf type: D = deciduous, E = evergreen; tree type: C = conifer, H = hardwood. Burn variables used in the analysis: Burn severity: UA = unburned alive, UD = unburned dead, BBMi = bark burned to the midpoint of the tree, BBMa = bark burned to the base of the tree; Burned/unburned: U = unburned alive or dead, B = burned at any severity
