Abstract
  • This paper discusses opportunities for developments in spatial clustering methods to help leverage broad scale community science data for building species distribution models (SDMs). SDMs are critical tools that inform the science and policy needed to mitigate the impacts of climate change on biodiversity. Community science data span spatial and temporal scales unachievable by expert surveys alone, but they lack the structure imposed in smaller scale studies to allow adjustments for observational biases. Spatial clustering approaches can construct the necessary structure after surveys have occurred, but more work is needed to ensure that they are effective for this purpose. In this paper, we describe the role of spatial clustering for realizing the potential of large biodiversity datasets, how existing methods approach this problem, and we formalize the problem statement which we call the Site Clustering Problem. We conclude with a discussion on the improvements made by methods introduced in this paper and the impact this can have on future ecological research and conservation decision making processes.
