There were eight key objectives for the Isobel project in 2005-06:
(1) establish site preparation treatments and plant seedlings in each of the 72 site preparation x livestock exclosure treatments within each of the 12 harvest treatments,
(2) collect hemispheric photographs to determine ground-level light conditions at the site preparation vegetation plot locations (72x30=2160),
(3) collect initial post- site preparation treatment measurements of soil nutrients, scorch height and forest fuels in relation to site preparation,
(4) prepare a report for journal submission on the short-term effects of harvesting on understory vegetation composition and biomass,
(5) upgrade a selection of vegetation permanent sample plots to provincial growth and yield standards, and provide regeneration data for the provincial PrognosisBC calibration process,
(6) extend the current TASS model scenarios to include (a) group and patch retention harvesting, (b) assess the likely effects of regeneration density on stand structure, and (c) assess the likely effects of insect attack on stand structure, and to complete a report for publication on these analyses,
(7) maintain an updated metadata structure for the Isobel project, and (8) continue with extension to forest management audiences.
