• In degraded stands, it has been foreseen that all of the growing stock will be cut by clear cutting and planting will be made instead of it.
• Pinus sylvestris stands in which crown closer is 1, if planting under the forest canopy is made, the available growing stock for the first treatment will be taken of 20%, and light cutting for the second treatment are foreseen. It was foreseen to cut 50% of the remaining growing stock, and 97% of the remaining growing stock in the removal cutting that is the following treatment.
   if clear cutting is made, 97% of the growing stock will be cut clearly in the first treatment, and planting will be made instead of it.
• Pinus sylvestris stands in which crown closer is 2, if shelterwood method is made in 20% of the available growing stock in the seed cutting that is the first treatment. It was foreseen to take 50% of the remaining growing stock in the light cutting that is the second treatment and 96% of the remaining growing stock in the removal cutting.
   If clear cutting is made, 97% of the growing stock will be cut clearly in the first treatment and planting will be made instead of it.
   If planting under the forest canopy is made as 20% of the available growing stock in the first treatment, it is foreseen to take 50% of the remaining growing stock in the light cutting that is the second treatment, and 97% of the remaining growing stock in the removal cutting.
• Pinus sylvestris stands in which crown closer is 3, shelterwood method will be applied as 40% of the available growing stock in the seed cutting that is the first treatment and it was foreseen to take 50% of the remaining growing stock in the light cutting that is the second treatment and 96% of the remaining growing stock in the removal cutting.
• The 3-4% of the growing stock left in the regeneration areas was left as a value tree for ecological and biological balance.
c) Tending areas – Njega šuma; it was foreseen to make tending to all fields except for reforestation and regeneration fields in accordance with the plan technique. During the preparation of the spatial patterns of tending areas, primarily the spatial distribution of the tending areas and the size of annual tending areas are taken into consideration. The study area is divided into ten different tending blocks, cutting map and tables are organized. In the research, ten different tending blocks have been formed and each tending block was divided into ten sub-blocks within itself and numbered. The treatment years have been defined as the first treatments and will be completed from 2015 to 2024; and the second treatments from 2025 to 2034 according to the sub-blocks within each tending block hierarchically. Since the cutting transitions within the planning unit have to be given to the local people living in the nearest settlement place in accordance with the legislation, the spatial distribution of tending areas have been made. Depending on the development stages of the stands, the silvicultural treatment method changes and low thinning method is applied in Pinus sylvestris basically (Table 7).
The tending allowable cuts are calculated after the forest inventory. The trees in the sample areas taken in the field are evaluated one by one in the forest inventory, and the intermediate yield allowable cut based on the silvicultural treatments technique is determined. The tending allowable cuts identified on the basis of the stands are reassessed in the office. At this point, some factors such as the forest function presented by the forest area, management purpose and conservation targets, social pressure factor, the stand parameters, ecological conditions, road conditions and the technical capacity of the forest enterprise are effective.
RESULTS AND DISCUSSION
REZULTATI I RASPRAVA
As a result, in the forest management plan of Hisar Forest Planning Unit, 244,293 ha of area has been decided to be forested, and to make tending cutting in the 8946,83 ha of
