(i) successional stage;
(ii) species composition;
(iii) stand structure;
(iv) patch size and shape;
(v) habitat connectivity and fragmentation;

(viii) habitat type.
department shall design timber harvests to promote long-term, landscape-level
diversity through an appropriate representation of forest conditions across the
