Summary
The Nature Park Medvednica, which is V protection category, according to the IUCN categorization implies recreation beside landscape preservation management in terms of natural protection, tourism and recreation, as well as scientific research, biodiversity preservation, education and sustainable exploitation of natural resources. The forests represent basic value of this area and condition its purpose and management. It has been determined that habitat diversity indices vary dependently on data spatial resolution. The habitat map M 1:25,000 showed to be the most appropriate (compared to 1:50,000 and 1:100,000 scales) for the analyses of the Park’s management and for certain areas the data of higher spatial resolution would be desirable. Data on plant diversity, and previously calculated landforms diversity per MTB 1/64 grid units were used as well. When identifying the tourist and visiting areas of the Park it is necessary to include biodiversity value of the area in order to sustainably manage among nature and cultural protection and tourist exploitation. The GIS usage in nature protection management is justifiable and very efficient, enabling the generation and collection of multidisciplinary data as well as spatial model projection obtained using these data, helping in prompt decision making, saving time and resources.
Key words: landforms, GIS, habitat map, vegetation map, diversity index
INTRODUCTION
Uvod
In assessing protected areas there are several difficulties to be encountered in regard to biodiversity, ecosystem, clean air and water safety, as well as overall nature protection since these are economically difficult measurable parameters. The value of non-commercial goods and services is necessary to express in monetary terms, wherever possible (WCPA, 1998). Excessive exploitation might occur in case when protected area is not correctly evaluated which decreases ecological goods and services value (Hat, 2003; Jenkins et al., 2004.). World trend indicates decreased
