“…Commensurate with this is the need for long-term research because in many temperate forest ecosystems it may take up to two decades (or longer) to establish relationships between soil disturbance and tree growth (Morris and Miller 1994). In addition to this validation, there is also a need for compliance (implementation) and effectiveness monitoring of soil disturbances to demonstrate management success and track these with the longer-term effects, so changes to criteria and standards can be made as new research data become available (Curran et al 2005a).…”

“…Implementation of these guidelines involves development and maintenance of policy, guidance documents and training, monitoring, reporting protocols and research that facilitate application of improved technical knowledge and practical experience. This is best done in an adaptive management framework, pairing the operational efforts with the generation and tracking of new research (Curran et al 2005a).…”

The challenge for all agencies managing public or private forest lands is to develop resource management policy and procedures based on the best available information. Science-based resource management occurs through an adaptive management process that includes three types of monitoring: implementation (compliance), effectiveness, and validation (research). Continued research, and the establishment of new trials is required to support soil conservation efforts and to investigate new concerns, such as climate change, bio-fuel harvest, and changing practices. Cooperative scientific networks and other collaborations are required to secure benefits from a common approach to soil disturbance management and reporting under various provincial/state, national and international sustainability protocols such as the Montréal Process. The technical session on Forest Soil Disturbances at the 2006 Annual Meeting of the Canadian Society of Soil Science in Banff, Alberta, is one step in collaboration, and brought together a group of experts from across Canada, and some from the United States of America, to share knowledge and experience and to discuss issues related to soil disturbance effects, policies and practices on forest lands. Selected papers are presented in this special issue on Forest Soil Disturbance, with this background paper focusing on the types of scientific support activities needed for science-based management of forest soil disturbance. Key words: Soil compaction, adaptive management, soil conservation, Montréal Process, natural resource management, monitoring

“…Concurrently, disturbance categories should be revised under an adaptive management process (Curran et al 2005a), as results become available from monitoring, operational trials, and research studies like the Long-Term Soil Productivity (LTSP) network (Powers et al 2005). Consistent categories would enable those defining best management practice guidance (BMPs) and thresholds for severity and extent of disturbance to maintain soil productivity and hydrologic integrity to be consistent with disturbance category definitions.…”

Soil disturbance from forest practices ranges from barely perceptible to very obvious, and from positive to nil to negative effects on forest productivity and / or hydrologic function. Currently, most public and private land holders and various other interested parties have different approaches to describing this soil disturbance. More uniformity is needed to describe, monitor, and report soil disturbance from forest practices. We describe required elements for attaining: (1) more uniform terms for describing soil disturbance; (2) cost-effective techniques for monitoring or assessing soil disturbance; and (3) reliable methods to rate inherent soil susceptibility to compaction, rutting, mechanical topsoil displacement, and erosion. Visual disturbance categories are practical for describing soil disturbance. Soil disturbance categories for the Pacific Northwest are described in detail to illustrate essential elements for attaining Element One. A number of potential products are listed to meet the other elements. Completion of these will facilitate collecting comparable data and sharing research and training information. Coordinated efforts will also ensure a more seamless process for assessing and reporting for sustainability protocols, and responding to third-party certification protocols. Additionally, these products will improve operational relevance of research results.Key words: soil disturbance, forest productivity, hydrologic function, monitoring, Montréal Process, risk ratings for soils, soil compaction, soil displacement, soil erosion, sustainability protocols, third-party certification RÉSUMÉ La perturbation du sol au cours des travaux forestiers varie de presque imperceptible à très évidente, accompagnée d'effets positifs, nuls et négatifs sur la productivité forestière ou encore sur les fonctions hydrologiques. Actuellement, la plupart des propriétaires de terrains publics ou privés, ainsi que les groupes de personnes intéressées soutiennent différentes approches de description de la perturbation du sol. Une plus grande uniformité est requise pour décrire, surveiller et faire état des perturbations du sol suite à des travaux forestiers. Nous décrivons les éléments requis pour obtenir (1) des termes plus uniformes pour décrire les perturbations du sol, (2) des techniques efficaces en terme de coût pour surveiller ou évaluer les perturbations du sol et, (3) des méthodes fiables pour classer la susceptibilité inhérente du sol en terme de compaction, orniérage, de déplacement mécanique du sol de surface et d'érosion. Les catégories visuelles de perturbation sont utiles pour décrire les perturbations du sol. Les catégories de perturbation du sol pour le Nord-Ouest du Pacifique sont décrites en détail afin d'illustrer les éléments essentiels requis pour atteindre le Niveau Un. Plusieurs détails supplémentaires sont énumérés dans le cas des autres niveaux. Ces mesures faciliteront la collecte de données comparables et le partage d'information reliée à la recherche et à la formation. Des efforts concer...

Influence of mechanized timber harvesting on soil compaction in northern hardwood forests

Evaluating and refining methods to minimize soil compaction during timber harvesting is important for maintaining soil health and long-term forest productivity. This is especially important when harvesting methods change over time. In this study, a hybrid harvesting method was used with the trees cut by one machine, in-forest processing of trees by other machines, and transporting the wood to the roadside by a forwarder on silt loam soils during the summer months. Two methods for sampling soils with mixed horizons in logging trails were developed to determine the baseline values of soil bulk density for longterm monitoring and to compare soils from nonmixed B horizons with those of B horizons from nontrafficked areas. For both methods, paired soil samples, in and outside of logging trails, were collected to determine the difference in bulk density between trails and nontrafficked areas. Soil compaction in trails was greatest where the soils adjacent to trails had low bulk densities and for locations that were closest to landings. These results are important in the context of climate change, as more summer logging is expected to occur in areas traditionally cut in the winter because of longer frost-free periods and more winter precipitation occurring as rain. More logging during the expanding snow-free season could translate to a greater degree of compaction and longer soil recovery times over a larger portion of the forested landscape.
