Landscape-level diversity in the BWCA depends on a fire-made mosaic of successional stages.

Evidence

If the unit of concern is a large region like the Canoe Area, however, and not just individual stands, then diversity for tht whole ecosystem is a function of both tht composition of individual communities and their relative abundance and arrangeIn& on the landscape. Maximum divcrsit$y here is attained with a full spectrum of successional stages and community types patterning the landscape, arranged like patches on a quilt. There would be new burns, early postfire successions, maturing pioneer forests, midlife stands showing invasion of shade-tolerant species: and very old communities. The scene, over time, would IX: like a slowly changing kaleidoscope. This is clearly the may it was in the primeval ecosystem. — Miron L. Heinselman, Fire in the Virgin Forests of the…, 411
