Bird Conservation Strategy for region 5 in Canada: identified threats

Table 4. Relative magnitude of identified threats to priority species within BCR 5 Pacific and Yukon by threat category and broad habitat class. Overall ranks were generated through a roll-up procedure described in Kennedy et al. (2012). L represents Low Magnitude threats; M = Medium; H = High; VH = Very High. Blank cells indicate that no priority species had threats identified in the threat category/habitat combination.
