What consequence is noted when *Crotalus oreganus* populations are removed from a local area?
Answer
Pressure on local rodent populations is released, leading to noticeable increases
The Western Rattlesnake exerts significant regulatory pressure on local rodent populations due to its specialized diet. When these snakes are actively present and controlling the numbers of mice, voles, and gophers, the ecosystem remains balanced. However, if these snakes are intentionally or unintentionally removed from a specific territory, this regulatory pressure immediately ceases. Consequently, the existing rodent populations are released from this primary source of predation, which frequently results in a noticeable increase in their numbers shortly thereafter, potentially leading to greater agricultural or structural pest issues.
