Download or read book Natural Regeneration of Subalpine Fir and Engelmann Spruce in Partially Harvested High-elevation Stands in East-central British Columbia written by O. A. Steen and published by British Columbia Forest Science Program. This book was released on 2008 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines factors affecting natural restocking of small openings created by partial harvesting of high elevation (> 1500 m) Engelmann spruce (Picea engelmannii Parry ex Engelm.)-subalpine fir (Abies lasiocarpa [Hook.] Nutt.) stands in east-central British Columbia, Canada. We examined the effects of opening size (0.03, 0.13, and 1.0 ha), seedbed, and seed supply on density of post-logging regeneration for 10 years post-harvest. The effect of opening size on growth release of advance regeneration was also examined. Both seed production and seedbed limited densities of post-logging seedlings. Densities of subalpine fir and Engelmann spruce post-logging regeneration remained low at two sites where seedfall was low. Seedbed scarification significantly increased seedling densities where seed rain was high. In the absence of scarification, abundant seed production had little effect on post-logging seedling densities. Increased height and basal diameter growth of advance regeneration following logging was greater on 1.0-ha than 0.13-ha and 0.03-ha openings. This study demonstrates that post-logging natural regeneration in combination with advance regeneration can restock small openings in partially harvested stands where there is an adequate distribution of mineral soil seedbed and logging or site preparation coincide with or shortly precede a year of abundant seed production.

Book excerpt: Excerpt from Natural Regeneration of Engelmann Spruce After Clearcutting in the Central Rocky Mountains in Relation to Environmental Factors Soil surface and subsurface, soil profile, and air pro file temperatures were summarized to characterize the microenvironment associated with seedbeds so that comparisons could be made between seedbed treat ments for each aspect. Soil surface temperatures and subsurface-soil and air-temperature profiles were aver aged to provide estimates of mean maximum diurnal temperatures.

Book Synopsis Natural Regeneration of Small Patch Cuts in a Southern Interior ICH Forest by : Jean Heineman
Download or read book Natural Regeneration of Small Patch Cuts in a Southern Interior ICH Forest written by Jean Heineman and published by . This book was released on 2002 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost all harvested sites in the interior cedar hemlock (ICH) zone of British Columbia are currently planted, but natural regeneration can be a viable reforestation alternative in small patch cuts or where a partial canopy is retained. This report describes a project in which five small, variable-sized patch cuts in an ICH forest were studied to determine the effects of opening size, edge characteristics, and substrate quality on the distribution & composition of natural regeneration. Results are presented & discussed regarding regeneration at four years after harvest.
Book Synopsis Factors Influencing the Density of Natural Regeneration in Uniform Shelterwoods Dominated by Douglas-fir in the Sub-boreal Spruce Zone by : Philip Joseph Burton
Download or read book Factors Influencing the Density of Natural Regeneration in Uniform Shelterwoods Dominated by Douglas-fir in the Sub-boreal Spruce Zone written by Philip Joseph Burton and published by University of British Columbia Press. This book was released on 2000 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three replicates of a uniform shelterwood trial were established in even-aged stands dominated by Douglas-fir in the SBSdw1 variant northeast of Williams Lake, B.C., with initial harvesting conducted in the summer of 1991. Treatments consisted of a two-stage shelterwood leaving 50% residual basal area (RBA) after the first entry and a three-stage shelterwood leaving 70% RBA, with overstory thinning achieved by hand-falling or by feller-buncher. Treatment units were 1.4 ha in area, with an uncut control (100% RBA) at each site. Seedfall was monitored using ten 0.37 m 2 seedfall traps in each treatment unit, inspected twice a year from 1992 through 1998. The abundance of different ground surface materials was surveyed in 1990, 1991, and 1993. Controlled germination experiments were conducted in 1994, 1995, and 1996. on four seedbed materials (forest floor, live moss, rotting wood, and mineral soil) across all RBA levels. Surveys of the density of natural regeneration were conducted in 1990, 1991, 1993, 1994, and 1996. ... Results to date suggest that a low residual basal area, combined with a high level of forest floor disturbance, is preferable for enhancing conifer regeneration. It is tentatively recommended that a preparatory cut is not necessary for naturally regenerating Douglas-fir under a shelterwood overstory in this zone, and that the seed cut should leave less than 50% residual basal area.
