Lake Van is T & uuml;rkiye's largest lake, and within it lies Akdamar, a small seven-hectare island. In 2008, eight feral European rabbits were introduced to the island to attract tourists. With no natural predators, their population had increased to 3,000 by 2016, causing severe ecological damage, destroying almond trees, accelerating soil erosion, and damaging historical buildings through burrowing. In response, local authorities launched a management programme from 2016 to 2017, removing 1,500 rabbits through physical control methods such as live trapping, net trapping, and night spotlighting. However, funding shortages halted further efforts, and the population surged to an estimated 4,000-5,000 by 2023. The rabbits now occupy the entire island, degrading vegetation, diminishing ecosystem services, and threatening tourism. According to the assessment conducted in this study, the situation is classified as causing major ecological impacts under the Environmental Impact Classification for Alien Taxa and minor cultural effects under the Socio-Economic Impact Classification of Alien Taxa. Therefore, urgent, long-term management solutions are essential to prevent further degradation, with public awareness campaigns, community involvement, and education can help reduce human-mediated spread and promote responsible behaviour. Coupled with sustainable, effective management strategies, these efforts are vital to preserving the island's ecosystem and cultural heritage.

As an important ecosystem, the wild fruit forest in the Tianshan Mountains is one of the origins of many fruit trees in the world. The wild fruit forest in Emin County, Xinjiang, China, was taken as the research area, the spatial and temporal distribution of the wild fruit forest was inverted using random forest and PLUS models, and the 2027 distribution pattern of the wild fruit forest was simulated and predicted. From 2007 to 2013, damage to the wild fruit forest from tourism and overgrazing was very serious, and the area occupied by the wild fruit forest decreased rapidly from 9.59 km2 to 7.66 km2. From 2013 to 2020, suitable temperatures and reasonable tourism management provided strong conditions for the rejuvenation of wild fruit forests. The distance of the center of gravity of the wild fruit forest increased, and the density of distribution of the wild fruit forest in the northwest direction of the study area also increased. It is predicted that the wild fruit forest in the study area will show a steady and slowly increasing trend in places far away from tourist areas and with more complex terrain. It is suggested that non-permanent fences be set up as buffer zones between wild fruit forests, ensuring basic maintenance of wild fruit forests, limiting human disturbance such as overgrazing, and reducing the risk of soil erosion.

Grasshopper disasters threaten grassland animal husbandry, and overgrazing is widely recognized as one of the main causes of locust infestation in grassland regions. However, the impact of overgrazing on grasshopper disasters remains unclear. To address this knowledge gap, this study interviewed 541 households living in locust-prone areas in Inner Mongolia, China. The generalized Poisson model and OLS regression examined the relationship between herders' production behavior and locust disasters. The results showed that 42% of the herders had suffered from locusts more than three times over the past 15 years, with an average of 49 ha of grassland damaged per household. In addition, with the increase in grazing rates, the scale of locust disasters decreased before it increased. The results also showed that operating grassland areas and feeding forage reduced locust disasters significantly, while renting grassland areas and grazing rates worked oppositely. These results suggest that grazing intensity can make a significant difference in the occurrence of locust disasters.
