Species composition and regeneration in cutblocks in mountain pine beetle areas

Forest Practices Board 2. Timing of Regeneration Cutblocks harvested between 1995 and 2000 Prompt reforestation is—or should logically be—an objective for cutblocks in areas affected by the  MPB epidemic. Regeneration timing was examined for cutblocks logged between 1995 and 2000, and  that had been declared as regenerated, in the MPB‐districts and in the low‐MPB‐districts. All of these  cutblocks [...] Pre- and post-harvest species composition 1995-2000 and 2000-2004 for MPB-districts 100% 90% 80% 70% Mixed Dec 60% Mono Dec Mixed Con 50% Mono Con 40% Mixed Pine 30% Mono Pine 20% 10% 0% Pre-harvest Post-harvest Pre-harvest Post-harvest 1995-2000 2000-2004 Forest Practices Board FPB/SIR/15.

The Growth of Mono-Pine Areas Large areas of similar‐aged mono‐pine may be considered undesirable, as the risk of future  infestations of MPB is increased. Therefore, the investigation looked at the total area regenerated in  mono‐pine over the two time periods—1995 to 2000 and 2000 to 2004—in the MPB and the low‐MPB  districts.  Figure 3 [...] Species conversion on 24,000 hectares of mono-pine and mixed-pine forest in the three MPB-districts for stands harvested between 2000 and 2004 14000 12000 10000 Area of forest 8000 cover (ha) 6000 4000 2000 0 Pre-harvest Post-harvest Mono-Pine Mixed-Pine Conifer Deciduous Following the harvest of 10,000 hectares of mono‐pine forest, 7,455 hectares of mono‐pine and 2,545  hectares of other species [...] Baker Creek Landscape Unit The Forest Practices Board is tracking the management of mountain pine beetle for a number of resource values in the Baker Creek landscape unit, west of Quesnel.
