Dead wood (dead standing tree (snag), woody debris (WD), buried wood, and stump) abundance was estimated in Newfoundland balsam fir (Abies balsamea (L.) Mill.) black spruce (Picea mariana (Mill.) BSP) forests regrown following natural anthropogenic disturbances. Although harvesting left few snags standing, disturbances generated many snags. Most were still 2 years after disturbance, but almost all had fallen 33–34 years. Snag then increased stands aged 86–109 Natural little WD 0–2...
The effect of harvesting and slash piling on soil respiration, temperature moisture was examined in a balsam fir (Abies balsamea) black spruce (Picea marinara) forest located western Newfoundland, Canada, 2 mo to 2.5 yr following harvesting. Within 4 harvesting, temperature, moisture, respiration rates were affected by piling. Clearcut areas without (CC-S) had significantly lower than uncut forests (F). However, clearcut with cover (CC+S) higher CC-S. When harvested combined, decreased the...
Deadwood (woody debris (WD), standing dead trees (snags), stumps, and buried deadwood) abundance was estimated in Labrador humid high-boreal black spruce (Picea mariana (Mill.) BSP) forests regrown following natural anthropogenic disturbances. Aboveground deadwood (DW) similar to values observed other boreal experiencing drier or warmer climates. Clear-cut harvest generated large amounts of WD, which had almost completely decomposed 34–36 years harvesting, with a fitted volume reduction rate...
The mass of carbon (C) in standing trees on 1.5 M ha Tasmanian State forest was 163 Tg C, with 139 eucalypt forest. highest C densities occurred the tallest, crown cover, mature, wet forest, representing 0.2% by area containing only 1.3 C. Shorter mature forests lower cover contained 21–68% this density. Rainforests and regrowth or silvicultural regeneration components also densities. Landscape-level saturation could be achieved when all simultaneously This would sequester an additional 93...
Successful regeneration following harvesting or natural disturbance is a fundamental prerequisite for sustainable forest management. However, some regenerating stands have poor juvenile growth rates, which compromise management objectives. In particular, the presence of ericaceous species that proliferate after disturbance, such as Kalmia angustifolia, can slow succession boreal to point ecosystem retrogression induced. We used data from silvicultural field trial established in central...
Growth rates of young conifers can be poor on disturbed sites dominated by Kalmia angustifolia L. Hence, a conifer revegetation trial was established -dominated site to evaluate the effects various silvicultural options and planted species selected soil organic layer characteristics. Larix laricina (Du Roi) K. Koch, Pinus banksiana Lamb., Picea mariana (Mill.) BSP seedlings were in plots with or without control herbicides. The effect fertilizer amendment also assessed. Seventeen years...
Deadwood (dead standing tree (snag), woody debris (WD; downed deadwood), buried wood and stump abundance) was estimated in northern hardwood forests of Nova Scotia dominated by Acer saccharum, Betula alleghaniensis, Fagus grandifolia, papyrifera rubum. Three strata were examined (1) old forests, (2) clearcut 1–2 years before measurement (3) 8 measurement. stocks low compared with deadwood reported for similar southern inland forests. 62–88 per cent WD, amounting to 11–37 Mg ha−1. No snags...
Quantification of stand and forest C stocks in response to different disturbances is necessary develop climate change mitigation strategies evaluate accounting tools. Live tree, dead woody debris (WD), stump, buried wood, organic mineral soil are described chronosequences black spruce ( Picea mariana (Mill.) BSP) (harvest fire origin) balsam fir Abies balsamea (L.) Mill.) (insect harvest origin). The largest were found (≤179 Mg·ha –1 ), (≤123 live tree (≤93 ) pools. changed predictably with...
The exchange of carbon, primarily as the greenhouse gas carbon dioxide, between forests and atmosphere, gives forest managers opportunities to limit emissions through management. Options available reduce include 1) storing in landscapes, 2) wood products, 3) providing society with a low-emissions resource (wood products) substitute for alternative materials associated larger emissions. To evaluate trade-off dynamics each option must be understood. Here, above options are explained using...
Clearcutting Newfoundland boreal forests significantly reduced organic layer fungal and total microbial biomass in clearcut areas with without slash cover, compared forested plots. However, aerobically incubated respiration rates were highest layers from under slash, intermediate forests, lowest slash.
