Forestry activities are performed in the open air, difficult working conditions and under the influence of various risk factors. Forest fire workers who work in the forest fire extinguishing and cooling have worked at the greatest risk operations. The majority of these workers work in the status of seasonal workers. In fire season, the fire workers usually wear work clothes for the day and stay in barracks in the forest. Work clothes of fire workers are brightly colored to be visible in the forest, fire-resistant and suitable forest conditions. It is important that to provide easy movement, to be effective against air conditions and to conform to the body features of workers of forest fire clothing in terms of health and safety. In this study, it has been assessed that satisfaction levels of forest fires worker from work clothes. It was applied a questionnaire to 44 forest fire workers. Data were analyzed statistically and solutions were developed.

Several previous studies investigated performance of optimum bucking method on coniferous trees in Turkish forestry. In this study, economic gain of using optimum bucking method was evaluated in deciduous forest of Oriental beech ( Fagus orientalis ) trees in northeastern region of Turkey. Network 2000 program was used to run optimum bucking method in a sample application. The findings of sample bucking application in Giresun Forest Regional Directorate were deemed to represent the optimum bucking data in nearby regional directorates (Artvin and Trabzon). Then, the economic gain of using optimum bucking method in producing Oriental beech ( Fagus orientalis ) was estimated for whole northeastern region of Turkey. The capability of optimum bucking method was evaluated by comparing study results with the results from traditional bucking method. The results indicated that optimum bucking application using Network 2000 program increased, although statistically not significant, the average economic value of harvested deciduous trees by 14.37%, comparing with traditional method, mainly relying on loggers’ experiences. The overall economic contribution of using optimum bucking in producing Oriental beech ( Fagus orientalis ) logs was estimated as 2,686,182.93 Turkish Lira (TL).

To this end, first, work units maps (geomorphologic facies) were created using slope, geology, and land use maps. Using this method, work units were considered as the main unit of desertification and a map was generated for each index according to assigned weights, such that the qualitative map of the desired criteria were obtained using the geometric mean of indicators. Then, through integration and determining the geometric mean of layers obtained from criteria and finally classification of the obtained maps, map of the current status of desertification in the studied area was prepared. The obtained results indicated that 31.67% of the area was in the medium class of desertification (II) and 68.33% belonged to the intense class (III).

Considering discard the theory of climax and rangeland succession model in recent years especially in arid regions and shrub lands, the new theory known as the state and transition model is taken into consideration by natural sciences and environmental specialistsb in the world. In present study, state and transition model and its application in rangeland management will be discussed and wil be peresented a case study of Iran for more description. As a case study, Nir rangelands of Yazd province will be introduced. In this rangeland, both status of enclose and grazing livestock evaluated and grazing livestock has been introduced as threshold of these two conditions. Rangelands of arid regions are biologically fragile and in the case of little degradation, a long time will be needed for compensation. The definition of different situations, thresholds, transitions and indicators will help managers to follow change trend among different plant communities and establish an ideal community. But due to very slow and very small changes in arid regions rangelands, use of models in these areas is not possible. Keywords:  Model, state and transition, Nir of Yazd, threshold, arid region.
