Appendix 4: Silviculture Graphs


Ten Year Analysis: Silviculture surveys on Crown land have increased substantially in the last 10 years to meet the increasing need for planning and monitoring of silviculture activities.

 

Ten-year analysis: The use of prescribed fire for site preparation has decreased over the last decade. Since 1991/92, mechanical site preparation has been used for more than half of the total site preparation done each year, with fire used for less than one-third.

 

Ten-year analysis: Crown land planted has peaked in 1994/95 at 216,000 hectares. As the backlog of not satisfactorily restocked (NSR) land is regenerated, planting will continue to decline, leveling off over the next decade.

 

Ten-year analysis: Brushing has been maintained at steady levels because of the need to establish free-growing forests.

 

Ten-year analysis: Spacing of young coniferous stands has increased significantly through FRDA II (1991-1995), the Provincial Incremental Program, and initially through funding provided by Forest Renewal BC. Recent funding reductions have decreased the size of the spacing program.

 

Ten-year analysis: The need for fertilization is dependent on specific forest site conditions, and it varies each year.

 

Ten-year analysis: Pruning treatments which increase future wood value have increased substantially since 1991/92 through to 1997/98. Recent funding reductions have decreased the size of the pruning program.

 

The three-billionth tree was planted in 1993, the four-billionth in 1997.

 

Trees planted yearly reached an all-time high in 1996 with 260 million trees. Planting will continue to decline as the backlog of not satisfactorily restocked (NSR) land is regenerated.
