At present, many existing protected areas have not fully considered the impact of climate factors in their design. Therefore, it is urgent to introduce higher precision tools, such as satellite remote sensing monitoring combined with regional climate models, to optimize protection strategies. A major issue is the steady loss of natural habitats, which is driving some high-risk snakes in Southeast Asia and Africa into densely populated towns and villages (Martinez et al., 2024). The situation is urgent; action should begin now to stabilize species and keep ecosystems in balance. Practical steps include building cross-regional wildlife corridors, using tracking tools to monitor movements, and setting habitat management plans that can adjust to local conditions (Lourenço-De-Moraes et al., 2019). 5.2 Adaptive strategies in temperate and arid-zone snakes Living in cool and dry areas, many snakes are responding to climate change in their own ways. Taking the European grass snake as an example, the warming has brought a "double-edged effect": smoother reproduction and wider spread; But the decrease in snowfall makes it more difficult for them to survive through the winter (Elmberg et al., 2024). North American rattlesnakes are also adjusting - changing their wintering shelters, extending or shortening their resting periods, and changing their strategies during predation (Moreno-Rueda et al., 2009). These practices are currently effective; Once warming accelerates, the adaptation speed may be difficult to match (Liu, 2025). 5.3 Narrowing of adaptive limits in high-altitude snakes Pressure on high-altitude species is building. For the Sichuan mouse snake, dams and water projects have broken the riparian corridor and caused habitat fragmentation (Figure 2) (Song et al., 2023). Suitable areas keep shrinking, and rugged terrain further separates groups, limiting exchange. The Gran Chaco shows a similar pattern: smaller patches hold more species, and competition for food and shelter intensifies (Cabral et al., 2024). The core problem is speed—habitat is vanishing faster than evolution or behavior can adjust, raising the risk of decline.
