Aim of study: The main aims of this study were to determine of damage level to residual stand and soil disturbance from mechanized selection logging.Area of study: Mixed beech stands in Caspian forests, northern Iran. Material and methods: Point-transect and systematic plot sampling were used for assessing damages to soil and trees, respectively.Main results: 89% of forest soil area was undisturbed or shallow disturbed, and 5.2% was deep disturbed. Soil bulk density of top 10 cm in the winching corridors, ruts and skid trails were increased 10.7%, 20.6% and 32.1% respectively than controlled area. Frequency of damages to regeneration and trees were 12% and 11.2%. The frequency of damages to regeneration was increased with increasing of their heights, but frequency of damages to trees was decreased with increasing of their diameter. The most type of damages was bole wounds in sizes of 100 to 200 cm 2 within 1 m from the ground level, and deep wounds. The frequency of damages was different in tree species (p = 0.001). The mean size of bole wounds was 174 cm 2 , and the mean height of bole wounds was 70 cm from ground level. The intensity of wounds on trees bole were decreased with increasing of their heights from ground level (p = 0.02), while their sizes were increased (p = 0.001).Research highlights: Winching of logs was the main cause of damages to soil and residual stand. The detailed planning strategy will reduce damage to level which is acceptable and predictable.

“…A critical review of methods for assessing or monitoring soil disturbance and consultation with statisticians are needed before a reliable system is implemented. Because the amount and severity of soil disturbance is often used as a proxy for longer-term growth impacts and hydrologic functions, it is essential that soil disturbance types are calibrated as to their impacts on tree growth and hydrologic functions based on research studies (Curran et al 2005b).…”

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...

“…Ministry of Forests (BCMoF) scientists are responsible for both research and operational support, ensuring this integration. To have an effective adaptive management process for soil conservation, each jurisdiction needs to address three objectives: (1) more uniform terms for describing soil disturbance; (2) cost-effective techniques for monitoring and assessing soil disturbance; and (3) reliable, site-specific methods to rate soils for risk of detrimental soil disturbance (Curran et al 2005c). These are briefly discussed below:…”

“…This paper presents an adaptive management framework for soil disturbance that supports internal operations and policy as well as external reporting for due diligence in forest soil management. To support this framework, common language and key components should be defined and agreed upon (Curran et al 2005c). These components include clear definitions of the various types of monitoring, which are critical to the adaptive management process.…”

Soil disturbance guidelines should be based on comparable disturbance categories adapted to specific local soil conditions, validated by monitoring and research. Guidelines, standards, and practices should be continually improved based on an adaptive management process, which is presented in this paper. Core components of this process include: reliable monitoring protocols for assessing and comparing soil disturbance for operations, certification and sustainability protocols; effective methods to predict the vulnerability of specific soils to disturbance and related mitigative measures; and, quantitative research to build a database that documents the practical consequences of soil disturbance for tree growth and soil functions.Key words: soil disturbance; soil compaction; rutting; monitoring (implementation, effectiveness, and validation); criteria and indicators; Montreal Process RÉSUMÉ Les directives portant sur les perturbations du sol devraient être établies à partir de catégories comparables de perturbation adaptées aux conditions spécifiques du sol affecté et validées au moyen d'un suivi et de recherches. Les directives, les normes et les pratiques devraient être continuellement améliorées en fonction d'un processus de gestion adaptative qui fait l'objet d'une présentation dans cet article. Les principaux éléments de ce processus comprennent : des protocoles fiables de suivi pour évaluer et comparer les perturbations au cours des opérations et pour des protocoles de certification et de durabilité; des méthodes efficaces de prédiction de la vulnérabilité de certains sols en matière de perturbation et des mesures de mitigation qui s'y rattachent; et, des recherches quantitatives pour élaborer une base de données qui documente les conséquences pratiques de la perturbation du sol sur la croissance des arbres et les fonctions du sol.
