The Rollers or Coraciidae (Passeriformes) are distributed in Africa, Asia, Europe, Australia, and New Guinea. The family has two genera including Coracias with nine species and Eurystomus with four species. Of this species diversity, only European Roller (Coracias garrulus) and Indian Roller (Coracias benghalensis) are found in Iran. Evolutionary biologists have always emphasized the importance of recording contact zones for sister species and relatives. The occurrence of hybridization in Coraciiformes was reported at about 14%. The reproductive range of European and Indian roller is broadly geographically separated, however their geographic distributions are in contact in eastern Iraq, western and southern Iran, and Pakistan. There is no information on the contact zone and hybridization between the two species. Therefore, in this study the distribution of these two rollers in the Fars province (southwestern Iran), contact zone and hybridization were investigated in fieldworks conducted during spring and summer in 2017 and 2018 years. The results showed that the European Roller was distributed throughout all of Fars province except narrow range in the south of the province but the distribution of Indian Roller is more restricted to the southern and western half of the province, so the two species has overlapping zones in the southern half and western parts of the province. In the present study, no hybrid specimens were observed in terms of plumage colors.

Brown bear (Ursus arctos) is the largest carnivore of Iran with a holarctic distribution in Europe, Asia, and North America. In Iran, its distribution is restricted to the mountain forest areas of Alborz and Zagros and Fars province is on the southernmost distribution boundary for this species worldwide. Iran's brown bears recognized as U. a. syriacus, which has discrete populations at high risk, and there is a critical lack of knowledge concerning different aspects of its biology. This research was carried out in order to identify its distribution pattern and conservation planning for four years in Fars province. As direct observation of brown bears is difficult due to its nocturnal activity, signs are usually used in such researches. A total of 170 signs of this species were recorded in Fars province. The most signs are traces (about 48%) and scat (about 20%). Investigation of the signs and the mapping of the species in Fars province using ArcGIS 10.3 showed that the highest presence of this species belongs to Mountains areas of Marvdasht (32.54%) and Sepidan (31.95%) in the northern parts of the province with a height range of 1600 to more than 2800 meters above sea level. Based on the obtained results it can be concluded that brown bear faces conflict with humans by attack on humans, domestic livestock, honey hives, fish farms and agricultural products in the province.

Zoning and implementation of strict program for each zone must be done to procurement of management goals in protected areas. In order to evaluate the ecological potential of Kuh-e Gorm, non-hunting area (83410 ha) in Fars province, possibility of its conversion to a protected area and land management, zoning has been performed using GIS software. Thus, to pursue this purposes, nocturnal and daily surveys were done to identify vegetation communities and animal species. Ecological and socio-economic resources were initially surveyed and mapped (1:100.000). Overlaying of different maps, created final map of environmental units (with 625 environmental units). Table of environmental units was completed and positional data were analyzed, then area was zoned for mentioned purposes. The result show that 7 zones are possible in the area as follows: 10.74% of the area is suitable for restricted nature reserve, safe area zone 31.86% for protected area zone, 2.40% for restricted use zone, 46.88% for extensive use zone, 4.11% for rehabilitation zone, 0.61% for special use zone and 3.40% for buffer zone. In total 42% of allocated zones are suitable for conservational proposes. Some animal species such as Capra aegagrus, Lutra lutra, Dryomys nitedula, Aquila chrysaetos, Falco tinnunculus, varanus griseus and Testudo graeca are important in term of conservational value.
