2 Action 1.2. Develop knowledge on the impact of different forest management practices on biodiversity. Review the knowledge on how forest management systems/plans can maintain and enhance biological diversity while ensuring their economic viability. 1. Title of Project Inventaire regional permanent des ressources forestières. Regional forest inventory. 2. Objectives of Project Biodiversity parameters (plant diversity as the basis of biodiversity sensu lato) have been included in the regional forest inventory, on the basis of scientific contribution from the universities 3. Potential Contribution to the Implementation of the Action Impact of different forest management practices on biodiversity: As about sample plots are observed in a ten years cycle basis, many interpretation will be possible on the relationship between biodiversity and stand structure, management and other characteristics of the forests. 4. Actor(s) Division de la Nature et des Forêts (Regional forest service), Forest Resources Direction, team Regional forest inventory. 5. Methods, Time Frame and Geographical Scope Systematic and permanent grid of sample plots (1 plot per 50 ha). Each plot is visited every ten years (see page in annex). 6. Sources of Further Information A detailed publication will be available in mid 2000, giving results for the whole set of indicators, including biodiversity indicators. 1

4 Action 1.2. Develop knowledge on the impact of different forest management practices on biodiversity. Review the knowledge on how forest management systems/plans can maintain and enhance biological diversity while ensuring their economic viability. 1. Title of Project Etude des impacts de la gestion forestière sur la biocénose en Région wallonne. Study of forest management impact on biodiversity in Wallonia. 2. Objectives of Project - A better knowledge of effects of forest management and sylvicultural practices on local or regional biodiversity (by studying selected taxa). - Which sylvicultural methods have we to use when the aim is the conservation or improvement of biodiversity? 3. Potential Contribution to the Implementation of the Action Impact of different forest management practices on biodiversity: Comparison of richness and diversity of indicator taxa ( vascular flora, insects, birds) in six forest types ( evenaged coniferous high forest, evenaged beech high forest, evenaged oak high forest, unevenaged coniferous high forest, unevenaged beech high forest and unevenaged mixed high forest) and tree development stages (regeneration, young forest, mature forest) in Belgian Ardennes. Maintenance and enhancement of biodiversity trough management systems/plans: The results of the study will allow to define silvicultural guidelines. 4. Actor(s) Université Catholique de Louvain (Forest Unit) and Division de la Nature et des Forêts (Regional forest service) 5. Methods, Time Frame and Geographical Scope Periodic inventories of species in 22 selected stands. Planned as s three years study. Geographical scope: Belgian Ardennes ( ha of forest) and bordering regions of Germany, Luxembourg and France. 3

6 Action 1.2. Develop knowledge on the impact of different forest management practices on biodiversity. Review the knowledge on how forest management systems/plans can maintain and enhance biological diversity while ensuring their economic viability. 1. Title of Project Recherche sur l intérêt patrimonial des lisières forestières et leur gestion en zone 5b. Research on patrimonial value of forest edges and their management (in an objective 5b area). 2. Objectives of Project To propose better management methods of forest edges, optimising their economical, ecological and landscape functions. 3. Potential Contribution to the Implementation of the Action Maintenance and enhancement of biodiversity trough management systems/plans: Publication of a Manual of management methods for different types of forest edges. (This manual, in French, is sent to the Liaison unit by postal service). 4. Actor(s) Faculté Universitaire des Sciences Agronomiques de Gembloux. Faculty of Agronomical Sciences of Gembloux, Belgium, by demand of Division de la Nature et des Forêts (Regional forest service) 5. Methods, Time Frame and Geographical Scope Six months study, in a pilot area (two forest district). Geographical scope: Belgian Ardennes ( ha of forest). 6. Sources of Further Information See the manual sent by postal service. Available on the website 5

8 Action 1.2. Develop knowledge on the impact of different forest management practices on biodiversity. Review the knowledge on how forest management systems/plans can maintain and enhance biological diversity while ensuring their economic viability. 1. Title of Project Etude de techniques sylvicoles améliorant la biodiversité. Study of silvicultural methods improving biodiversity. 2. Objectives of Project To propose management methods of coniferous and broadleaves forest, taking into account main species of birds of the Birds directive (79/409/CEE). 3. Potential Contribution to the Implementation of the Action Impact of different forest management practices on biodiversity: In 3 pilot areas from the Special Protection Areas, evaluation of birds behaviour (for a few target-species ) in various stand structures. ( species and stages patterns). 4. Actor(s) Faculté Universitaire des Sciences Agronomiques de Gembloux. Faculty of Agronomical Sciences of Gembloux, Belgium, by demand of Division de la Nature et des Forêts (Regional forest service) 5. Methods, Time Frame and Geographical Scope Combination of stand typology and birds censuses. Geographical scope: Wallonia ( ha of forest), especially Special Protection Areas of the Bird Directive. 6. Sources of Further Information 7

10 Belgium Walloon Region Additional information Data collected by the regional forest inventory in Wallonia. (Summary) Classical data are in normal type characters. New SFM data are in bold type; data related to biodiversity are in italic type. These observations and measures are collected in a systematic gridnet of about permanent sampling plots (1 plot for 50 hectares of forest area). General and administrative data. - number of IGN MAP; number of plot; co-ordinates; date and time of measure. - forest district ( cantonnement forestier ), province. and commune (administrative subdivision) - ecological territory and forest region (referring to maps) - type of owner (+ identity for public owners) - size of the forest - classification of the plot (forest/non forest; productive/non productive ) Environmental data - topography: relief, exposure, slope, elevation. - soil : - type of humus, texture, drainage, soil depth, type of soil (map type) - soil sampling for ph and analysis of main nutrients (on a sub-sample of one plot for 500 ha) - phytosociology: list of plant species ; association; ecological group. Stand data - stand history - stand type and structure - clear-cut felling: species, age of cut stand, size of clear-cut-felling - deforested areas: species, age of neighbouring stand, - burned area - area damaged by storms and wind - sylvicultural practices: pruning, type and intensity of thinning, selected trees, spatial distribution of trees, etc. - health of the stand - stand quality: technological quality, proportion and list of main defects. - game damages and protection measures against game damages. - regeneration: regenerated area, stage, regeneration method. - timber conditions. - edge study (length, type) - for soil or water protection area: clear-cut felling area; artificial drainage. - evaluation of forest functions: production, game, conservation, protection... 9

11 Belgium Walloon Region Additional information Dendrometric measures For each tree of the plot: - species, girth, co-ordinates of the tree, stem height, tree layer, wood quality, health status. - timber marking - stand age for evenaged stands - species proportion (for unmeasured plots) - tree main species regeneration (area, stage) - dead and damaged trees (girth, length, dead causes) - dead wood volume - imber volume (evaluation of removed trees by stump measures) ir.
