Suitability of Native Broadleaf Species for Reforestation in the Cariboo Area of the Southern Interior Forest Region

This document evaluates the long-term viability of planting native broadleaf trees as a reforestation strategy in British Columbia's Cariboo region. By tracking species like aspen, birch, and cottonwood alongside traditional conifers over a ten-year study period, the authors discovered that planted broadleaves suffered from poor survival rates due to wildlife browsing, frost, and competition from grass. While these deciduous trees naturally excel at enhancing soil nutrients and providing frost protection for understory seedlings, the study concluded that they are currently less reliable than conifers when manually planted. This document suggests that while broadleaves remain vital for forest biodiversity and health, their successful management in this region relies more on robust natural regeneration than on artificial cultivation.
