Every field season seems to yield a “theme” of organisms, no matter what the target species is for the study. Sometimes, unexpected results occur. This field season found some significant habitat alteration via storm damage at various Eastern Worm Snake (Carphophis a. amoenus) sites. Population numbers of this species were smaller than usual and could be a result of a more open canopy in damaged areas. An open canopy potentially results in an increase in the amount of moisture evaporating from the soil and increased soil temperature. For a fossorial species, hot dry soils don’t always make the best habitat.
A recheck of Smooth Green Snake (Liochlorophis vernalis) sites also saw population differences. One survey, of a once prolific site for this species, yielded zero individuals. However, plenty competitors such as the Redbelly Snake (Storeria occipitomaculata) and predators such Eastern Milk Snake (Lampropeltis triangulum) were abundant.
Long term studies and rechecks of sites help gather valuable information on population trends that are needed to better understand how species interact and thrive as habitat and climate change.
