Abstract
Kusalan habitat is located on a northwest-southeast mountain with an intensive topography near the Sarvabad town in the
west of Kurdistan. This habitat encompasses a set of unique bioenvironmental phenomenon (such as Quercus forests and
dense ranges) as well as three permanent rivers and numerous springs. So far, there was no study on the bioenvironmental
habitat potentials. This persuaded us to conduct a research on the bioenvironmental potentials of the region, to protect the
area, according to IUCN criterions. Field surveys, remote sensing and geographic Information System (GIS) were used to
identify and analyze the ecological, social and economical resources of the study area. Hybrid method was also employed
using digital classification of 10m SPOT5 image of 2005 and field data as visual interpretation. Applying this method, the
potential resources were identified. Then the maps of land forms, Hydrology, soil, vegetation, wildlife habitat, ecological
potentials, current applications and the conventional boundaries were provided. In the next stage, bioenvironmental units
were determined through applying GIS analysis along with gathering the maps and overlaying them. Zoning of the
bioenvironmental resources was performed on the basis of IUCN definitions. The results of this study demonstrated that the
study area involves 224 of flora species and 195 of fauna species as well as 5 main zones including: 29% secure zone,
40.75% protection zone, 13.7% alternative recreation zone, 3.21% mass recreation zone and 0.14% cultural and historical
zone and 13.2% reconstructing zone along with the many scientific and training values and a unique wild natural landscape.
Thus, Kusalan habitat is worth to be introduced as a national park (II) and to be considered as one of the four national
protected areas in Iran. According to the results of this research, the GIS and RS can be used for identifying inaccessible
bioenvironmental resources with an intensive topography and providing their maps with the aim of protecting the area,
based on IUCN criterions.
1- Introduction
Establishing protected areas is considered as a conscious
attempt to support the last remainders of a biodiversity which
preserved their natural properties in the current instable
developing process. Applying scientific principles to study the
bioenvironmental potentials and evaluating the ecological
potentials determines the land use type and the natural potential
(ecological potential) (makhdom, 1999). These studies has been
already conducted in traditional ways by using the ground data
collection, however, this method was an expensive, time
consuming method and in some cases difficult to access. To
address this problem, remote sensed images are used to study
the natural resources, forests, ranges, wild life, erosion and
other bioenvironmental factors (chaderi 1996). Consequently,
studying the ecological potentials of western habitats of
Mazandaran, involving forests, ranges, apparent animal types
such as some kinds of Mammals, birds, reptilian, etc. seems
very necessary.
2- Materials and Methods
Ecological resources include biological and physical sources,
each of them involving different parameters. In general, 3
methods of identifying ecological sources include:
1- Inventory and sampling
2- Automatic visual interpretation of aerial photographs,
remotely sensed images and topographic maps
3- Geographic information system (Makhdom, 1999).
At first, a supervised digital classification method was applied
using a maximum likelihood classifier. To do this, seven
groups of training samples were selected as a model of spectral
reflectance for different phenomena in the study area (including
water, Gardens, planted crops, unplanted crops, forests,
pastures, rocky lands and manufactured areas) based on the
ground survey data.
The resulted map has a total accuracy of 57.4% and a kapa
coefficient of 72.3%. Then, a visual classification method was
applied. To do this classification, the raster map was transferred
to a vector one. In the next step, the obtained map was laid on
SPOT 5 panchromatic image. Then, it was interpreted,
reviewed and edited using ground data in an Arc view 3.2
environment. The resulted map had a total accuracy of 65.15%
and a kapa coefficient of 78.65%. This matter indicates the
high capability of spot5 data associated with using a hybrid
classification method to provide maps of the mountainous and
non accessible areas. Ecological resources include:
2-1 Physical sources: Due to lack of a meteorological station
in the study area, we used Synoptic station of Marivan and
Paveh which are located near Kusalan. Rivers and Brooklets
were extracted from topographic maps and remote sensed
images. Then, they were digitized. The registered points were
transferred to GIS in order to identify the existing springs.
Ground samples and geographic characteristics of springs
obtained by GPS system were used. In the next stage,
hydrographic maps of the Kusalan area were also provided.
