Bird Conservation Strategy for region 7 in Ontario: identified threats

Table 5: Relative magnitude of identified threats to priority species within Bird Conservation Strategy (BCR) 7 ON by threat category and broad habitat class. Only threats with a population-level effect were considered, and 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.
