Investigating the destructive effect of Hystrix indica on pine trees in Khajir National Park and providing a solution to control it

Wild pistachio or pistachio (Pistacia atlantica) is one of the plants that has been allocated a surface for its growth in different regions of Iran. This plant is used in the production of gum (turpentine) and its use in the production of medicinal and sanitary materials, protection of water and soil and prevention of soil erosion, use of its fruit and foliage as fodder in animal feeding, preservation of wildlife and The resort value and also as a native plant that has a high tolerance to harsh environmental conditions including drought is of great importance. Therefore, it is necessary to protect this species against the threats and dangers it faces. In the last few years, with the increase in the population of Teshi due to reasons mainly of human origin, such as the lack of proper waste management and the increase in changes of use to agricultural lands and gardens in and around Khajir National Park, in addition to these cases, the decrease in the population of leopards (Panthera pardus tulliana) in this The region, as one of the main prey eaters and hunters of Tishi, we are witnessing an increase in the population of Tishi and the damage of Tishi to agricultural lands and gardens and more importantly to Baneh trees in Khajir National Park, which can subsequently cause a decrease in the level of Baneh forests in this region and increase soil erosion. to be The methods of physical control of Tshi population such as trapping, hunting by dogs, electric fences and guarding will have very little effect and in addition, biological control of the species will be hardly possible. In order to protect the trunks of trees in Khajir National Park against the damage of the trees, it is recommended to use wire nets. The resistance of wire nets against oxidation and wear is a key component in determining the type and structure of wire nets. The implementation program of the Chinese netting solution of the trunk trees to protect against drought in Khajir National Park was carried out in 2 phases from the beginning of August 1402 to the end of September 1402, and the third phase of the program is also underway.
