Description of Bird Conservation Region 6 : identified threats

Table 4a. Relative magnitude of identified threats to priority species within Bird Conservation Region (BCR) 6 by threat category and broad habitat class.
Overall ranks were generated through a roll-up procedure described in Kennedy et al. (2012) Table Footnotea. 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.
