Habitat destruction is one of the important factors in species extinction. Ecosystems provide a variety of services to humans, and humans need a set of these services to survive. For this purpose, the present study was conducted to identify the objectives of the Habitat Restoration Plan for the management and protection of vegetation and wildlife in the winter of 2020. To achieve the objectives of the present study, resource review was performed using the keywords Habitat Restoration and Search Restoration Ecology in online digital libraries. According to the findings of the present study, the process of ecological Restoration consists of three aspects including vegetation structure, ecological process and ecological performance. A successful habitat Restoration project also pursues four major global priority priorities, Including Regeneration, Ecosystem restoration, Rehabilitation, and Regeneration. Achieving the goals of Habitat Restoration requires a greater understanding of the ecological factors that enhance the success of the regeneration project. Water resources management is very difficult and complex.

This study was conducted to identify and investigate changes in the size, type and number of habitat patchs in Mashkid Wetland in 2010 and 2020. For this purpose, in the spring of 2020, habitat patchs were identified through field operations and by objective observation. Ground control points were prepared with the aim of assessing the accuracy of the final classification maps by recording land cover information and location of each type of patchs using a global positioning device. Landscape structure map was drawn through visual interpretation of phenomena using Google Earth satellite images. Arc GIS 10.3 software was used to prepare the final land use structure classification map and calculate the area of the patchs. The percentage of each patch in the heterogeneous land was determined by Excel 2013 software. According to the results, the landscape mosaic of the region in the spring of 2010 had habitat types of plants, rocks and alluvial areas and in the spring of 2020 consisted of habitats of plants, shrubs, rocks and water surfaces. A total of 131 patchs were identified and counted in 2020 and 40 habitat patchs in the landscape structure of the region in 2010. In 2010, poor vegetation patch had the highest percentage of area compared to the whole region and in 2020, water patch had the highest percentage of share. Overall, the results indicate significant changes in the size, variety and number of habitat patchs over time.

Habitat assessment is one of the pillars of wildlife management and protection. In the study, the evaluation of Pika habitat in Adoroshk watershed was performed using the maximum entropy algorithm model (MaxEnt). According to the principles of cartography from the geographic reference map topography to extract the boundary of the region, the digital height model for the preparation of the classified map (Dem) of elevation changes, Slope and geographical domain were used. In order to prepare the environmental layers to enter the model MaxEnt, ArcGis software version 10.3 was used. Sampling was performed using random linear transect method and binoculars through direct observation of cheeks and indexes in spring and summer of 2019 and the number 33 points of Pika,s presence were recorded by GPS. Validation of the model was performed using the area under the curve (AUC) and the usefulness of the variables by analyzing the Jacknife test. The results showed that the desirability of Paika habitat in the Adoroshk watershed is mainly in rocky and mountainous areas with grass and shrubs at altitudes above 2500 meters above sea level and slopes. It is more than 50%. The climate was considered suitable for temperate pike. Favorable areas for Paika constitute 275 hectares (17.46%) of the habitat. It was also found that in Adoroshk, Paikas prefer the western slope.

Different species of wildlife provide many services. Accordingly, in this study, the identification of wildlife with medicinal value of Adoroshk watershed and their distribution map was studied. For this purpose, in the spring and summer of 2019, through field visits and random linear transect method, habitat wildlife was identified and to prepare wildlife distribution maps, species presence points were located by a locator. It was recorded globally. Dispersion maps were prepared in the Google Earth software environment through visual interpretation of phenomena and information from field visits and ground control points. The final drawings were prepared in Arc GIS 10.3 software environment. The results showed that in Adoroshk, there are 11 species of medicinal mammals belonging to 7 families and 4 orders, of which the highest frequency belongs to the herbivorous species, the Capra aegagrus with 57 heads and the lowest number belongs to the species. Carnivores; Panthera pardus, Vormela peregusna, Martes foina and Hyaena hyaena are observed at once. The order of carnivores with 5 species has the highest number and the order of Erinaceomorpha with one species has the lowest number of medicinal species. Also, 6 species of birds with medicinal properties belonging to 3 families and 3 orders were identified and counted. Among them, the highest number belongs to Alectoris chukar with 193 pieces and the lowest number belongs to Columba palumbus with 2 pieces and the total number of medicinal birds observed in this study was estimated to be 392 pieces.

Zoning is a well-accepted method of keeping nature walkers away from ecologically sensitive and valuable areas. In this research, considering objectives such as; Introduction and feasibility study of Lipar region for tourism development, protection of biodiversity of the region and evaluation of the capabilities of Google Earth software and method of visual interpretation in simulation of regions, zoning of Lipar region was discussed. Ground control points were recorded during field visits and photographs of the area with the Global Positioning System. The ground reality map, the final zoning map and the calculation of the share of each zone were prepared in ArcGIS software version 10.3. Identification of vegetation and wildlife of the area was done through direct observation using a random method. The results of the analysis of the final classification map of the region showed that Lipar has 13 types of zones and the salt field has the lowest percentage and shrublands and grasslands with low density have the highest percentage. Also, 2.67% of the area has been affected by human construction. The results showed that areas such as sandy beaches, rocky areas and areas with vegetation on the surface of the lagoon are considered sensitive wildlife habitats. Also, in this study, 4 plant species, 6 bird species and 2 reptile species were identified.
