This study examines the impact of climate change on altitudinal movement patterns and number individuals four large mammal species within Central Alborz Protected Area (CAPA) region Mountains, a biodiversity hotspot, over 23-year period (1999 to 2022). During warm season (May 25-September 29), temperatures were reported have increased by 2-2.5 °C, while relative humidity was observed decreased 4-4.5%. Compared past two decades (2000-2022), Caspian red deer initiate their annual high-altitude migrations 15-20 days earlier, with in summer range increasing more than threefold. Wild goats also migrated peak arrivals from 20-36 (1999-2003) 36-57 (2018-2022) between May 25 31, highlighting temperature as primary driver herbivore movement. In contrast, brown bears exhibited subtle movement, likely influenced both humidity. boars, an approximate 40% increase individuals, tended return lower elevations earlier previous years (1999-2003). These highlight role significant regulator ecology, influencing habitat use. However, human-induced barriers, such roads settlements, present additional threats these seasonal migrations. underscores urgent need for adaptive management strategies, including protection corridors, expansion core zones, enhanced community engagement, support resilience under changing climatic conditions.
