Lasy w Polsce stanowią blisko 30% powierzchni kraju. Jest to obszar pełniący różnorodne funkcje biotyczne, ochronne, produkcyjne i reprodukcyjne. Artykuł relacjonuje rozumienie koncepcji zrównoważonego rozwoju w leśnictwie. Przedstawia model wielofunkcyjnej gospodarki leśnej zapewniającej trwałe odtwarzanie lasów, a także sposoby planowania działań w lesie.

Forests in Poland constitute nearly 30% of the country's area. It is an area that performs a variety of biotic, protective, production and reproductive functions. This article introduces the concept of sustainable development in forestry. It presents a model of multifunctional forest management ensuring sustainable forest reproduction as well as ways of planning activities in the forest.

Tourism and recreation may help in development of local communities, especially in regions without well developed industry and agriculture. An example of such an area are Rychtal Forests. However, there are barriers to overcome in order to benefit from tourism development in the Rychtal Forests. No valuation of these forests and other areas as regards their usefulness for tourism and recreation was made so far. There was no comprehensive inventory of places attractive for tourists. There is no necessary infrastructure (tourist routes, places for rest, accommodation base). A lot of institutions manage the region (12 local communities, 2 forest districts, an Experimental Forest District, a Promotional Forest Complex). There are no funds for development of infrastructure, investments in accommodation, promotion). The example of successful undertaking in the field of tourism on forested areas is French Project - Retrouvance. This is a program based on common values of forests and non-forested areas. It is a proposal of a week-long route. The aim of the route is to discover nature. Retrouvance is based on proper relationships between visitors and hosts. It respects natural environment. If it is possible, in the places designated for accommodation renewable energy sources and wooden objects are used and effective waste management is organized.. Following the example of Retrouvance, .Let us discover Rychtal Forests. project was implemented in 2005. The aim of the project is preserving cultural heritage of rural areas, participation in local development and high quality of tourist services with due respect to environment. The first stage of the project consisted in organizational and information activities. In the second stage initial valuation of areas was made by local communities and places attractive for tourists and existing tourist infrastructure were identified. The information was marked on maps. Information collected from individual local communities were elaborated in the form of GIS. A system covering the whole area of the Rychtal Forests was created based on GIS systems for forests in individual administrative units. Three categories of objects were created: natural, historical and elements of infrastructure. Individual points received identifiers and were linked with descriptive base. The next stage was data verification in the field according to strictly approved rules common for the whole area. Verification was made by forestry students during scientific camp. Each object was described by means of standard forms. Actions taken so far are only the initial stage of the project implementation. Next action will be to mark out tourist routes. GIS will be used for this purpose. Planned routes should avoid high-density housing, industrial areas, busy roads, railways, stores of waste, etc. Simultaneously, the routes should reach the most interesting places of the region. The final course of the routes has to be consulted with all institutions concerned. The routes should take into account existing and planned accommodation, which should be situated in such way that it would be possible to divide the route into one-day sections. The final stage will be working out detailed principles of cooperation of institutions, decision on necessary investments and collecting funds. Expected advantages from the project are, first of all, the following: development of the region, change of incomes structure in forests and an increase of public interest in forests.

Satisfying the needs in respect to constantly growing demand for transport services, especially for road traffic, is based on development of the roads system with diverse technical parameters. Location of a road very often leads to formation of a conflict area, where functional restrictions of the hitherto existing ways of exploitation are involved. These restrictions mostly concern the areas of great natural value, including forest ecosystems. Location of roads within forest areas brings limitations in performing their economic, social, recreation functions and above all their role in environment and landscape preservation. The study proposes a set of criteria and indicators of the forest valorisation in terms of location of roads of high national and voivodeship ranking. The indicators of protective, economic and spatial nature have been discussed. The presented rules of valorisation should form grounds for elaborating a valorisation method whose results could serve as a helpful tool in implementation of newly planned road investments according to the least harmful variant for the forest areas.

The paper presents a system based on a computer programme which enables automation of valuation of forest functions. In the work the valuation system prepared in the Forest Management Department of the Agricultural University in Poznań (in the scope of methodical basis) was used. The method is based on three-step division of forest functions (protective, productive and recreational) and on appraisal of selected values on the level of a stand. For the appraisal a point-weight method of valuation was applied. The automation of forest functions valuation enables relatively fast control of correctness of the applied method under conditions of a concrete object (a forest district) and then verification of selected parameters assessing values and functions of the examined area. The appraisal of individual values consists in working on a great number of input data which has been very time-consuming so far. The use of computer techniques (programme preparing) allowed not only to streamline the process itself but also to eliminate potential mistakes. The programme used data from Computer System of the State Forests (SILP) and enabled preparing basic data for the needs of visualization of a forest numerical map. The programme was prepared and tested with the use of the SILP base and the forest numerical map of the forest district .wieradów. The valuation of forest functions for the forest district .wieradów encompassed 5772 stands. It has been proved that there is a relative balance between groups of functions. The group of recreational functions prevails (37.31% of valuated stands). The group of productive functions has slightly lower value . 36.15%. The group of protective functions has the lowest value . 26.53%. The analysis of the division of stands into degrees of multifunctionality showed that forests close to multifunctional constitute 31.11% and multifunctional forests constitute 30.11% of stands. The domination of the group of recreational functions in the area is justified by the fact that the area is very attractive for tourists, relatively easy accessible, with good tourist infrastructure. It occurred that neither the SILP nor the forest numerical map are sufficient source of data for valuation based on the tested method, although they are functioning flawlessly in the Forest District .wieradów. The assumption accepted in the initial stages was verified (It had been assumed that the system may facilitate introduction of principles of forest functions valuations into forest practice and it may contribute to acceleration of development of this aspect of management works). An efficient valuation system demands both wider data base of stands and corrections in the method of evaluation. There is also a need for standardization of data structure in the bases of the SILP (strict standard of the SILP). Such research directions and implementation works enable to use results of valuation for example to fix forest functions, and as a consequence, to form proper productive and protective recommendations. They may also accelerate research on a multifunctional forest model.
