Forest harvesting in mountain caribou range has been an issue for many years. Radiotelemetry studies on mountain caribou in the last decade have helped identify the geographic areas of conflict, improved understanding of the mechanisms by which forestry activities affect caribou, and suggested new approaches to management. Forest harvesting has begun to impact population of northern caribou, and researchers have begun to examine those impacts. Interest in integrating forest management and caribou habitat management has increased and has manifested itself in two ways: experimentation with special stand management practices intended to maintain or create caribou habitat, and the creation of tools to help managers make decisions in a landscape context.

Habitat management for woodland caribou (Rangifer tarandus caribou) in southeastern British Columbia has generally focussed on protecting old-growth forests from logging. As that strategy becomes more difficult to maintain, biologists are beginning to explore opportunities to manage second-growth stands to provide arboreal lichens and other habitat resources important to caribou. Special harvesting and stand management practices are being developed and formulated into strategies for maintaining caribou populations in managed stands.

Abstract Visualization is a powerful tool for depicting projections of forest structure and landscape conditions, for communicating habitat management practices, and for providing a landscape context to private landowners and to those concerned with public land management. Recent advances in visualization technology, especially in graphics quality, ease of use, and relative ease of learning, make it readily usable by natural resource managers. Concerns about the appearance of even-aged practices, which have the greatest potential to enhance wildlife diversity, have constrained forest management. We developed realistic visual simulations to display the outcomes of forest management practices used to create and maintain a range of wildlife habitat conditions in New England, and to project future landscape appearance for periods up to 100 years. We describe the simulation process so that it can be used elsewhere. Realistic visual images can be a useful tool to clearly display habitat management alternatives for landowners and participants in public land management and to improve communication about the long-term appearance of the landscape as periodic treatments are applied.

This paper examines suspended sediment concentration and stream discharge during freshet in three small sub-boreal forest streams (<1.5 m in width) in the central interior of British Columbia for 1 year prior to (1996) and for 5 years following forest harvesting (1997–2001). Harvesting prescriptions in a 20-m strip beside one stream required complete removal of merchantable timber (>15 cm diameter at breast height (DBH) for pine and >20 cm for spruce), while all stems <30 cm DBH were retained beside a second stream. A third stream remained unharvested as a control. The two riparian treatments were prescribed to test the efficacy of current British Columbia legislation that allows for varying amounts of riparian retention as best management practices for the management of windthrow. Both treated watersheds were clear-cut harvested (approximately 55% removal) in January 1997, and in the following year, temporary access roads were deactivated, including two stream crossings in the low-retention watershed. An increase in peak snowmelt and total freshet discharge was first noted in the second spring following harvest in both treatments and remained above predicted in all subsequent years. Suspended sediment also increased during freshet following harvest but returned to levels at or below preharvest predictions within 3 years or less in the high-retention watershed.

Moisture Contents

We examined the effects of forest harvesting on the net exchange of methane (CH4) between the atmosphere and sandy soils in two mature slash pine (Pinus elliottii Engelm. var. elliottii) plantations in northern Florida. Before each of the stem-only harvests, soils in these plantations were net sinks for CH4 (-0.03 to -2.6 mg CH4·m-2·d-1) on all but one sampling date. On this one pre-harvest sampling date, soils in one plantation were net sources of CH4. This emission coincided with an average soil moisture content of 83% water filled pore space (WFPS), which was significantly greater than the average soil moisture contents (25-66% WFPS) for all pre-harvest sampling dates. After harvesting, soils in both plantations became net sources of CH4. Average emission rates from harvested soils ranged from 3 to 11 mg CH4·m-2·d-1. Harvested soils were net sources of CH4 for at least 1 year after the harvest. However, the duration of the post-harvest CH4 emission period was reduced by bedding the plantation soils, a typical post-harvest site preparation treatment. Bedded soils in harvested stands were either relatively small net CH4 sources (0.2 mg CH4·m-2·d-1) or net CH4 sinks (-0.4 mg CH4·m-2·d-1). Soil CH4 fluxes were highly correlated with soil moisture contents (r2 = 0.66 and 0.71; significant at p < 0.05), which were strongly influenced by climate and forest management practices. For example, soil moisture contents for one of our sites, averaged over the pre-harvest, post-harvest, and post-harvest-plus-bedding periods were 46, 68, and 38% WFPS, respectively. Our results suggest that increased soil moisture in southern pine plantations induced by either precipitation events or forest management changes the direction of the soil CH4 flux from sink to source.

Risk Of Predation

Caribou (Rangifer tarandus) living in the mountainous areas of British Columbia are usually classified as either northern caribou, which spend much of the winter in low-elevation relatively young forests foraging primarily on terrestrial lichens, or mountain caribou, which winter in high-elevation old subalpine forests foraging exclusively on arboreal lichens. The forest-management practices necessary to conserve caribou differ substantially between these two categories of animals with different life-history strategies. Because of this variability in winter-habitat use, information relating specifically to Takla Lake caribou was required for forest management. To provide this information, we radio-collared 15 female caribou in two subherds in the vicinity of Takla Lake and determined their distribution and movements between January 1996 and May 1998 in relation to topography and vegetation cover. Habitat selection was examined using a classified satellite image. At the landscape scale, Takla Lake caribou avoided low-elevation forests (presumably because of the associated high risk of predation from wolves (Canis lupus)), occupying small seasonally overlapping home ranges (mean 151 km2) at intermediate and high elevations. Within home ranges in all seasons, caribou were most often found in the forest but, relative to availability, they selected forests only during calving. When in the forest, caribou selected open hybrid white-Engelmann spruce (Picea glauca × Picea engelmannii) - subalpine fir (Abies lasiocarpa) forests over lodgepole pine (Pinus contorta) and deciduous forests in all seasons except spring. Caribou selected open spruce-fir stands over dry and closed spruce-fir stands in all seasons except calving. We conclude that caribou feed primarily on arboreal lichens in winter, because the open spruce-fir forests that they use have moderate to high arboreal lichen abundance, deep snow, and few terrestrial lichens. Takla Lake caribou were not typical of either mountain or northern caribou, but as is typical of insular populations of any species, have adapted to the food, topography, and cover types available to them on their mountain islands in a sea of moose (Alces alces) and wolves.

Recent Increase

Natural regeneration will continue to play an important role in forest management practices in British Columbia despite the recent increase in artificial regeneration. It is anticipated that by the time the artificial regeneration programme has been fully developed, up to fifty per cent of the areas logged will be restocked artificially, leaving the other fifty per cent to restock naturally.

The Impact

&lt;p&gt;The development, the alternative pathways for use of bioresources, can lead to plausible stressors in the future on forestry dominated catchments. It is needed to analyse the impact of regional future projections on different land system management (LSM) attributes. The catchment scale projections are downscaled from Nordic Bioeconomic Pathways (NBPs), the subsets of Shared Socioeconomic Pathways (SSPs). As a case study, the Simojoki catchment (3160 km&lt;sup&gt;2&lt;/sup&gt;) in northern Finland has been considered where drained peatlands and forests dominate (53%) in the catchment. We integrated stakeholder-driven input, Finnish forest inventory model pathways (MELA) and hydrological catchment model (SWAT) to explore the future consequences of forest management practices for different NBP scenarios. We calibrated and validated water quality parameters in SWAT for the Simojoki catchment. Then, based on the output of MELA model of LSM attributes including stand management, catchment management strategy and fertilizer use, we used NBP scenario projections in SWAT model. We also included stakeholders&amp;#8217; evaluations of biomass removal at the time of harvesting at the Simojoki catchment. Additionally, climate imposing emission scenarios have been integrated into SWAT model to analyse longer perception of climate change (CC). The final outcomes of the proposed scenarios (NBP and/or CC&lt;strong&gt;)&lt;/strong&gt; will portray the probable impacts on each LSM attribute in the Simojoki catchment, to adapt to the future forest management consequences.&lt;/p&gt;

Natural resource managers, environmental interest groups, and public agencies need identifiable, measurable indicators of sustainability based on meaningful fine-scale specifics that are appropriate for both fine and increasingly broader social/ecological scales. The "Identify the Specifics" framework, field tested in Ontario, Saskatchewan, and British Columbia, uses collective local expert knowledge to integrate and prioritize social/ecological concerns that become the foundation for both local and increasingly broader-scale indicators of sustainable management. Results to date suggest that: (1) local experts have valuable knowledge to contribute; (2) identified local indicators, once reviewed, can contribute to both local- and broader-scale indicators; (3) fewer than 10 indicators may provide an adequate foundation for assessing the sustainability of local range and forest management practices; and (4) local and broader-scale experts commonly identify different indicators because they have different knowledge bases, priorities, and responsibilities. Differences in the indicators identified among experts representing different scales may be minimized if indicators at broader scales are developed with knowledge of specifics from finer scales. The Specifics approach is presently being used across British Columbia to help identify knowledge gaps and related research and extension priorities.

The Status

The natural conditions, climate change and socio-economic challenges related to the transformation from a socialistic society towards a market-driven system make the implementation of sustainable land management practices in Mongolia especially complicated. Forests play an important role in land management. In addition to providing resources and ecosystem functions, Mongolian forests protect against land degradation.We conducted a literature review of the status of forest management in Mongolia and lessons learned, with special consideration to halting deforestation and degradation. We grouped our review into seven challenges relevant to developing regionally adapted forest management systems that both safeguard forest health and consider socio-economic needs. In our review, we found that current forest management in Mongolia is not always sustainable, and that some practices lack scientific grounding. An overwhelming number of sources noticed a decrease in forest area and quality during the last decades, although afforestation initiatives are reported to have increased. We found that they have had, with few exceptions, only limited success. During our review, however, we found a number of case studies that presented or proposed promising approaches to (re-)establishing and managing forests. These studies are further supported by a body of literature that examines how forest administration, and local participation can be modified to better support sustainable forestry. Based on our review, we conclude that it is necessary to integrate capacity development and forest research into holistic initiatives. A special focus should be given to the linkages between vegetation cover and the hydrological regime.
