Varanus griseus caspius (desert monitor) is a predator included appendix I of Convention on International Trade in Endangered Species; therefore, it is crucial to plan for its conservation. In this study, the suitable habitats of the desert monitor, Varanus griseus caspius, were evaluated in Iran, considering 10 environmental factors, for three periods of time: mid-Holocene, current, and years 2041–2060. Three individual models were produced to create an ensemble model: Generalized Boosting Model (GBM), Generalized Additive Model (GAM), and Random Forests (RF). Next, highly suitable areas in current and future periods were compared to the boundaries of conservation areas (CA). Among the different models projected, the ensemble model performed the best. The results indicated that so far, the distribution range of the species has shifted profoundly and will continue to grow in the future, while some currently suitable CAs will turn into unsuitable habitats for the species. We suggest further studies focus on redefining and broadening the CAs borders. Also, studying the species connectivity in current and potential future habitats can help to protect the species.

Varanus griseus caspius（沙漠监视器）是《濒危物种国际贸易公约》附录一的捕食者；因此，对其保护进行规划至关重要。在这项研究中，沙漠监测器Varanus griseus caspius的合适栖息地在三个时期内，对伊朗进行了评估，其中考虑了10个环境因素：全新世中期，当前和2041-2060年。生成了三个单独的模型来创建整体模型：广义提升模型（GBM），广义加性模型（GAM）和随机森林（RF）。接下来，将当前和将来高度合适的区域与保护区（CA）的边界进行了比较。在预测的不同模型中，集成模型表现最佳。结果表明，到目前为止，该物种的分布范围已经发生了深远的变化，并将在未来继续增长，而目前一些合适的CA将变成该物种的不合适栖息地。我们建议进一步的研究集中在重新定义和扩大CA边界上。也，
