  1. Change in aspen density over a range of height ratio classes in the SBPSxc

  2. IDFdk3 The vicious aspen was not as bad as it looked! 6 years old 20 years old ( not brushed)

  3. SBSdw1 Pine and aspen: a different story 10 year old pine

  4. Recommended changes from research trial results • Note: • Only for pine at free growing height • Only for zonal sites

  5. Research suggests that current provincial guidance with regard to aspen competition in pine stands could use some tweaking • Research is only on one site – is this valid? • We only studied pine and aspen but there are other species out there • Results we have developed are for pre-brushing surveys. What about post-brushing? • And what about other similar ecosystems? • What do you mean other values???? Could the changes affect something else?

  6. Verifying the broad application of the results • Why Verify? • Broad application of research results from just one site is not recommended:we collected information to determine if the research could be extended across the same unit • For inclusion of similar ecosystems: we can’t afford to complete research in every subzone so we collected data to determine if we could extend the research across other ecosystems • With operational assistance we sampled a range of operational sites across a variety of subzones.

  7. Other ecosystems in the Cariboo with aspen communities as defined by the “Expert System”
