What observation regarding movement patterns implies that finding multiple Eastern species individuals suggests a stable local population?

Answer

They maintain a relatively small home range, not traveling more than 125 meters on average.

The ecology of the Eastern Worm Snake is tied to minimal spatial movement, a feature that has implications for population density assessment. Studies focusing on the Eastern species have indicated that these snakes do not exhibit strong homing instincts that drive long-distance travel, instead maintaining a relatively small home range. On average, observations suggest these snakes do not travel distances exceeding 125 meters throughout their entire preferred range. Because their movement is so localized and limited, encountering several individuals within a small geographical area is highly indicative of a locally established, stable population that is successfully utilizing the available microhabitat resources.
