“…This indicates that the productivity of the ecosystem has not sufficiently recovered from the disturbance. The NPP in this site was similar to the NPP (72-447 g·C·m −2 ·year −1 ) of a regenerating boreal black spruce forest 3-12 years after disturbance [26], but smaller than the NPP (655-829 g·C·m −2 ·year −1 , assuming that C content of a plant is 0.5) of a naturally regenerating temperate forest where the canopy-forming trees recovered within four to six years [47]). To examine the process of carbon accumulation after disturbance, many studies have used a chronosequence approach [25,[27][28][29].…”

Quantitative evaluations of biomass accumulation after disturbances in forests are crucially important for elucidating and predicting forest carbon dynamics in order to understand the carbon sink/source activities. During early secondary succession, understory vegetation often affects sapling growth. However, reports on biomass recovery in naturally-regenerating sites are limited in Japan. Therefore, we traced annual or biennial changes in plant species, biomass, and net primary production (NPP) in a naturally regenerating site in Japan after windthrow and salvage-logging plantation for nine years. The catastrophic disturbance depleted the aboveground biomass (AGB) from 90.6 to 2.7 Mg·ha −1 , changing understory dominant species from Dryopteris spp. to Rubus idaeus. The mean understory AGB recovered to 4.7 Mg·ha −1 in seven years with the dominant species changing to invasive Solidago gigantea. Subsequently, patches of deciduous trees (mainly Betula spp.) recovered whereas the understory AGB decreased. Mean understory NPP increased to 272 g·C·m −2 ·year −1 within seven years after the disturbance, but decreased thereafter to 189 g·C·m −2 ·year −1 . Total NPP stagnated despite increasing overstory NPP. The biomass accumulation is similar to that of naturally regenerating sites without increase of trees in boreal and temperate regions. Dense ground vegetation and low water and nutrient availability of the soil in the study site restrict the recovery of canopy-forming trees and eventually influence the biomass accumulation.

“…Total N in aboveground parts of mature aspen (40-95 yr old) ranged from 220 to For personal use only. 660 kg N ha -1 (Kimmins et al 1985;Hendrickson 1988;Peterson and Peterson 1992;Wang et al 1995). Approximately one-half of the N was in the bolewood and bark.…”

“…The total K pool of the mineral horizons would be of the magnitude of 50 000 kg K ha -1 . The K removed in the harvested aspen would be about 130 kg K ha -1 (based on literature values from Alban et al [1978], Pastor and Bockheim [1984], Peterson and Peterson [1992], Wang et al [1995]). The losses of K would be negligible in terms of the total K in the soil; however, the K removed in the harvest was equivalent to about 25% of the extractable soil K (LFH and three surface mineral horizons).…”

. 1998. Soil nutrient and vegetation response to patch clear-cutting of an aspen forest near Meadow Lake, Saskatchewan. Can. J. Soil Sci. 78: 59-68. Alternate silviculture systems, such as small patch clearcuts, may become important in the development of sustainable forest management strategies in aspen forests. A study was initiated in a 64-yr-old trembling aspen (Populus tremuloides Michx.) stand in Meadow Lake Provincial Park, Saskatchewan to determine changes in nutrient dynamics and secondary succession following patch clear-cutting. One hectare replicated patch cuts were logged in the winter of 1993-1994. There was no site preparation following harvest. Annual vegetation, regeneration and soil and plant nutrient data were collected annually, 1 yr prior to, and 3 yr following harvest. Aspen regeneration was 48 375 stems ha -1 2 yr after treatment. Stand (alpha) diversity of the understory was not affected by harvesting, although annual species turnover (beta diversity) increased slightly after harvest. There was an increase in aspen foliar nitrogen (N) for 2 yr following harvest. Soil nutrient concentrations did not differ between patch cut and unharvested plots except total potassium (18% lower in the LFH of the harvested treatments 3 yr after harvesting). Small patch cuts with the litter horizon kept intact may be appropriate for aspendominated stands in the boreal mixed wood to minimize ecological disturbance while maintaining aesthetics within a park setting.Key words: Ammonium, aspen regeneration, diversity, nitrate, plant community structure, soil productivity Maynard, D.

Can. J. Soil Sci. 78: 59-68. Des systèmes alternatifs de sylviculture, comme la coupe à blanc par petites trouées, pourraient devenir une composante importante dans l'élaboration des stratégies d'aménagement durable des forêts de trembles. Nous avons étudié un peuplement de peupliers fauxtrembles (Populus tremuloides Michx.) âgé de 64 ans dans le parc provincial Meadow Lake, en Saskatchewan, afin de déterminer les modifications dans la dynamique des éléments nutritifs et la succession secondaire après une coupe à blanc par trouées. Au cours de l'hiver 1993-1994, une coupe à blanc par trouées a été pratiquée sur un hectare, avec répétition. Il n'y a eu aucune pré-paration du terrain après la coupe. Nous avons recueilli des données sur la végétation annuelle, la régénération, le sol et les éléments nutritifs, un an avant la coupe et, chaque année après celle-ci, pendant trois ans. La régénération de la tremblaie soumise au traitement a été de 48 375 tiges par hectare deux ans après la coupe. La diversité (alpha) de l'étage inférieur n'a pas été modifiée par la coupe, mais le renouvellement annuel des espèces (bêta) a augmenté légèrement après la coupe. Il y a eu une augmentation de l'azote (N) foliaire chez le tremble pendant deux ans après la...

“…Estimates of timing to canopy maximum were based on interpretation of yield tables (Alberta Forest Service 1985), previous Millar Western yield curves (Millar Western Forest Products 1999) and other literature (Lieffers and Stadt 1994, Wang et al 1995, Ryan et al 1997. In all simulations, LAI of mature conifer canopies varied between 2.3 and 3.5 annually and deciduous LAI varied from 2.9 to 3.2 inter-annually (dependent on annual rainfall and temperature).…”

The Forest Watershed and Riparian Disturbance (FORWARD) project input into the Millar Western Forest Products Ltd. Detailed Forest Management Plan consists of three main components: 1) watershed and stream layer maps and associated datasets; 2) soil and wetland layer maps and associated datasets; and 3) a lookup table that permits planners to determine runoff coefficients (the variable selected for hydrological modelling) for functional first order watersheds, based upon various site factors and time since disturbance. The watershed and stream layer component includes a hydrological network, a Digital Elevation Model, and Strahler classified streams and watersheds for functional first and third order watersheds in the entire Millar Western Forest Management Agreement area. Relatively coarse mineral soils (which drain quickly) and wetlands (which retain water) were the key features that needed to be identified for the FORWARD modelling effort; therefore, the soil and wetland layers represent a combined soil texture and wetland coverage. The runoff coefficient lookup table integrates predictions of hydrologic impacts of harvest into planning.
