Soil conditions and tree growth on rehabilitated and degraded sites: stewardship of BC's forest soils

Author(s): Bulmer, Chuck (BC Ministry of Forests)
Subject: Earth Sciences, Forestry
Series: Forest Investment Account (FIA) - Forest Science Program


This comprehensive and integrated project extends and enhances more than 5 years of research. Soil conservation efforts have reduced the amount of harvesting-related soil disturbance in BC's forests over the past decade, and soil rehabilitation techniques have restored productivity to degraded soils, but new information is needed to reduce costs and improve results. Our early results indicated that soil rehabilitation efforts were often successful; more recently, we evaluated soil physical conditions implicated in limiting tree growth on degraded soils. This project will improve soil conservation planning and stewardship of BC's forest soils by (1) providing updated information on tree growth for a number of rehabilitated sites to improve productivity estimates; (2) further investigating physical factors to improve planning and rehabilitation techniques for a range of soil types; and (3) developing and testing a methodology for the rapid and objective evaluation of soil compaction on forest sites in BC.
