Climate change is a pressing issue that impacts many areas of life, but have you ever considered how it affects reptiles and amphibians… or even your experience herping? As the clock ticks on efforts to slow or reverse climate change, its effects are becoming a reality we must adapt to and navigate in the years to come.

Temperature & Reproduction

One of the most significant ways climate change impacts reptiles is through rising temperatures. As cold-blooded animals, reptiles depend on external heat sources to regulate their body temperature, making them particularly sensitive to temperature fluctuations. While warmer temperatures might seem beneficial, specific temperature ranges are critical for maintaining their physiological processes. The extent of the impact varies depending on the species and location. For instance, lizards are projected to be among the most vulnerable, as their reproduction is closely tied to specific temperature thresholds. Similarly, snakes face comparable challenges due to their reliance on precise environmental conditions. Additionally, rising temperatures often lead to water scarcity, which can make it harder for reptiles and amphibians to find adequate water sources and food

Disease Vulnerability & Habitat Alterations

The rise in global temperatures and fluctuations in weather patterns significantly increase the risk of disease and habitat alterations for reptiles and amphibians. These creatures experience heightened stress as temperatures rise, which weakens their immune systems and makes them more susceptible to diseases and infections. For example, the chytrid fungus, which thrives in warmer, wetter conditions, and causes chytridiomycosis, a deadly disease that has already devastated amphibian populations worldwide. With continued warming, this threat is likely to grow. Similarly, reptiles are at an increased risk of contracting Upper Respiratory Tract Disease, which is exacerbated by environmental stressors.

Habitat destruction further compounds these challenges. Rising sea levels and more frequent wildfires are rapidly destroying critical habitats, forcing reptiles and amphibians to migrate to less suitable areas. These restricted spaces lead to closer contact between individuals, increasing the spread of diseases. Additionally, as reptiles move in search of new habitats, they may encounter unfamiliar pathogens, to which they have little or no immunity, further threatening their survival.

Looking Forward

While the challenges posed by climate change are significant, there is hope on the horizon. Studies have shown that some reptile species demonstrate the ability to adapt to changing environmental conditions. For example, certain lizards and snakes have adjusted their behavior and activity patterns to avoid extreme heat, while others have shifted their nesting or hibernation periods to better align with seasonal changes. These adaptations provide a glimpse of how resilient reptiles can be in the face of adversity.

As climate change continues to reshape our world, its impact on reptiles and amphibians and the ecosystems they inhabit, cannot be ignored. These changes also alter the experience of herping, challenging enthusiasts to adapt their practices and deepen their understanding of these fascinating creatures. From disrupted habitats to the spread of diseases, the challenges are immense, but so are the opportunities to make a difference.

Embarking on a herping tour is more than just a chance to observe reptiles and amphibians; it’s an opportunity to witness firsthand how these species are navigating the pressures of a changing environment. Herping can also play a critical role in conservation efforts, providing valuable data and fostering a connection with nature that drives awareness and action.
