Abstract

The goals of SCHIRP research this year were to study our existing silvicultural field trials to assess long-term gains in productivity arising from a variety of silvicultural treatments, to increase our understanding of the biological bases for the responses, and to assess the impacts of typical silvicultural treatments on biodiversity of soil organisms and vegetation. These factors were addressed in a coordinated, integrated, multidisciplinary research program involving partners from industry, government and academia. Recent trial re-measurements have indicated that fertilization may cause a long-term improvement in productivity of these sites, and that this hinges on the application of P along with N. This information assists in developing recommendations for best management practices on these sites and prediction of rotation-length improvements in wood supply as a result of silvicultural intervention. The stand development project is proceeding as planned, and the student now has the data needed to write the thesis. The belowground ecology research continues to provide us new insights into these organisms and their interactions. We have been successful in communicating our research results to foresters and scientists; extension activities this year included: SCHIRP workshop and field tours, SCHIRP Update #2 extension report, SCHIRP non-timber forest products newsletter, Stand Establishment Decision Aid, 4 conference presentations, 2 published journal papers, 4 papers accepted for publication, and 5 papers submitted for publication.
