2-2 Land Shape maps: To assess the parameters forming the
land shape (height classes, slope classes and five main
geographic directions) and to prepare the necessary maps, four
sheets of topographic maps at the scale of 1:50000 of year 1997
were used. Finally, the land shape maps were obtained by
overlaying the map layers of height, slope and geographic
direction.
2-3 Biological Resources
2-3-1 Plants: The extinction rates of plants in the study area
were measured after careful frequent ground checking at
different phonological stages of plant growth by collecting
vegetation samples.
2-3-2 Animals: The information about the animals in the study
area was collected by the wildlife habitat experts. To prepare
the wildlife scattering map, the animal species index was
determined. Then, habitat location was registered by GPS
device and spatial data was transferred to GIS environment.
The vector map of wildlife habitat was obtained through the
hybrid interpretation of remotely sensed images.
2-3-3 Land shape: Since the land shape is a qualitative factor,
remotely sensed images and a topographic map of 1:50000
associated with the field data were used to identify the scenery
of Kusalan area.
2-4 Socio-economical studies
Conventional boundary map was prepared via hybrid
interpretation of SPOT5 images and ground surveys with local
people.
2-4-1 Evaluating the Bioenvironmental Potentials: The
following processes are used in all methods of evaluating the
bioenvironmental potentials:
1- Ecologic resources identification
2- Socio-economic data collection
3- Ecologic data collection and analysis
4- Evaluating the ecological potential for each unit, then
comparing them with the ecological properties of each unit in
the model
5- Zoning
6- Providing the land use potentials in terms of the global
criteria
3- Results
The results of bioenvironmental resource identification
(ecologic and socio-economic resources) are as follows:
3-1 Ecologic resource
3-1-1 Physical resources: Results of studying the physical
resources show:
3-1-2 Climate: The Combination of climatic conditions in
Marivan and Paveh stations, and the average of climatic
parameters show the cold wet climate of Kusalan area.
3-1-4 Land shape: According the obtained results, there are
many mountains and elevations with crest or round tops in the
comice or precipices shapes. The walls of valleys often have a
steep or moderate slope, ending to bottom-line of brooklets.
Direction of brooklets is mainly observed in linear form having
a low width and a V shape profile view. The studies on
topographic factors demonstrated the mountainous high altitude
topography of Kusalaa Based on table 1 and map2, height
variation range is 1800m and the main height classes are 1200-
1800m in 40% of the study area. 27% of the area is covered
with 2000-2500m classes which are suitable for protection
according to evaluation models. Table 1 shows the percentage
and area of each slope class. Distribution of classes is
heterogeneous and the permanent predominant slope class is
30-60%. The slope above 60% covers 1/3 of the study area.
Based on the results of this study, the area for the classes is
north orientation (28/8%), west orientation (25/6%), east
orientation (25/1%), and south orientation (20/2%). Due to the
uniformity of area distribution of the main orientations, the
summer and winter time is proper for wildlife, so, animals
won't migrate to the neighbor habitats. Land shape was
determined by resultant of 3 physiographic factors of slope,
height, orientation. As the result, 509 small ecosystems are
obtained from Kusalan big ecosystem.

3-1-3 Hydrology: There are abundant steep slope brooklets
and springs in Kusalan habitat which all of them ends to Sirvan
River. The main springs of Kusalan include: Hooseian, Lar,
Odele, Hevar, Hevar Heye Shour.
3-2 Biological resources
3-2-1 Plants: 224 plant species were identified using field data
and through a process of plant collection and identification in
