THE NECESSITY OF HIGH QUALITY HABITAT WHEN YOU’RE LIVING ON THE EDGE: A CASE STUDY OF THE HUDSONIAN EMERALD
Although widely distributed at higher latitudes, the Hudsonian emerald dragonfly (Somatochlora hudsonica, Hagen) is more sparsely distributed and less common in Colorado, the southernmost edge of its range. Here, S. hudsonica is a sensitive species whose local distribution and specific habitat requirements are generally poorly understood. In this study, we estimated likely habitat for S. hudsonica in Boulder County, CO using both a literature-based habitat suitability index and species distribution models trained using prior recorded occurrences. We then ground-truthed these suitability maps by surveying for S. hudsonica at ponds and lakes across a range of predicted suitabilities within the county. Our literature-based habitat suitability index proved to be significantly higher at ponds where we found S. hudsonica compared to those where we did not observe the species. Furthermore, ponds where we found S. hudsonica tended to be at higher elevation, have a higher percentage of intact forest within 500m, and have better water quality than those ponds where S. hudsonica was absent. Together, these results indicate the necessity of protecting small, snow-fed mountain ponds from anthropogenic disturbances that would prevent them from providing adequate habitat for this thermally restricted species.
