V. Caboun 2010. New classification <strong>and</strong> utilization of forest functions in l<strong>and</strong>scape<br />

472<br />

This classification of forest functions creates a basic information base for the possibility of the<br />

utilization of the functions of tree species <strong>and</strong> their communities in the l<strong>and</strong>scape by human<br />

society.<br />

The aim is to construct the classification system for the assessment of the potential of forest<br />

functions <strong>and</strong> real fulfilment of the functions of a forest growing in different site conditions <strong>and</strong><br />

types of the l<strong>and</strong>scape with various use <strong>and</strong> degree of anthropic changes. An emphasis will be<br />

put on the real state of forest, its current tree species composition, age <strong>and</strong> spatial structure,<br />

ecological stability considering not only historical development but also present state as well as<br />

its expected development, global <strong>and</strong> regional (mainly climatic) changes <strong>and</strong> anthropogenic<br />

effects, <strong>and</strong> social requirements <strong>and</strong> the interests of the forests owners.<br />

A new important element in the utilization of forest functions is financial reimbursement paid to<br />

the forest owner for the provided services<br />

Philosophy of practical use <strong>and</strong> methodology in detecting, classifying <strong>and</strong> valuation of forest<br />

functions in the l<strong>and</strong>scape is expressed briefly in following points:<br />

• Setting apart a part of the l<strong>and</strong>scape for the assessment <strong>and</strong> valuation of forest functions<br />

• Ecological-functional typifying of determined part of the l<strong>and</strong>scape <strong>and</strong> attributing of<br />

corresponding (potential) communities of tree species<br />

• Evaluation of the difference of the structure of real forests with optimal structure of<br />

potential forests in the determined part of the l<strong>and</strong>scape<br />

• Determination of ecological-stabilization rate (effect) of real forests in the determined part<br />

of the l<strong>and</strong>scape (classification of ecological stability of forests <strong>and</strong> particular part of the<br />

l<strong>and</strong>scape)<br />

• Assessment of real functionality of forests <strong>and</strong> communities of tree species in the<br />

determined part of the l<strong>and</strong>scape from the viewpoint of their structure<br />

• Assessment of social requirements on the use of the determined part of the l<strong>and</strong>scape <strong>and</strong> on<br />

fulfilment of the functions by forest tree species <strong>and</strong> their communities<br />

• Appraisal <strong>and</strong> valuation of forest functions with regard to the type of the determined part of<br />

the l<strong>and</strong>scape <strong>and</strong> requirements on fulfilment <strong>and</strong> utilization of forest functions in the<br />

determined part of the l<strong>and</strong>scape<br />

• Proposal of management <strong>and</strong> measures to optimise the structure of forests <strong>and</strong> their<br />

functions in the determined part of the l<strong>and</strong>scape with regard to the state, ecological stability<br />

<strong>and</strong> financially grounded requirements on the use of forest functions <strong>and</strong> the functions of<br />

communities of tree species in this particular part of the l<strong>and</strong>scape.<br />

From the viewpoint of prediction of the development of fulfilment <strong>and</strong> utilization of the<br />

functions of tree species communities in the l<strong>and</strong>scape it must be noted that as it is possible with<br />

ecological stability to determine its probable development on the basis of supposed changed of<br />

site conditions <strong>and</strong> the structure of forest ecosystem, it is also possible to predict the<br />

development of the capability of this ecosystem to fulfil individual functions in the l<strong>and</strong>scape or<br />

environment. But it is very difficult to predict the need, capability <strong>and</strong> social willingness of the<br />

utilization of these functions with their adequate financial reimbursement.<br />

It is possible <strong>and</strong> appropriate to present in graph the comparison of potential <strong>and</strong> present<br />

fulfilment of the functions by tree species <strong>and</strong> their communities in the studied area.<br />

Similarly, real utilization of the functions of tree species <strong>and</strong> their communities on the studied<br />

territory as well as comparison of real utilization of the functions with social order can be<br />

illustrated in graph.<br />

4. .Discussion <strong>and</strong> conclusion<br />

From insinuated way is possible to compare real possibilities of particular ecosystem to fulfil<br />

required functions what subsequently shows the need of the management of this ecosystem. The<br />
