Table 1-A. Percentage area required as wildlife tree patches when landscape units have been designated and landscape level biodiversity objectives have been established ¹
% of the area available for harvesting in the biogeoclimatic subzone that has already been harvested without recommended wildlife tree or equivalent retention	% of the biogeoclimatic subzone within the landscape unit available for harvest
	90	70	50	30	10
10	7	5	3	1	0

Note: The table axes refer to the area of the landscape unit.

If leave areas adjacent to or outside of the block meet the required inter-patch distances and recommended patch area and composition requirements, then WTPs are not required inside the cutblock. However, these adjacent areas should be mapped and included in the silviculture prescription for tracking purposes.
