Abstract

Species Distribution Model (SDM) is a useful tool for conserving rare species. However, the ‘rare species modeling paradox’ presents challenges in modeling the rarest species, such as Corybas species, which have a narrow distribution and are known only from a few localities, making them difficult to model using conventional methods. An Approximate SDM (ASDMs) method was developed specifically for these species, employing a subtraction formula weighted by niche overlap metrics. This method was created in the hope that other rare species with between 5-20 occurrence records could also be modeled in the future. Our ASDMs demonstrated a good fit with directly modeled SDMs and successfully predicted the distributions of rare species with very few occurrence records. Hence, ASDMs present a promising and user-friendly approach for modeling potential distributions of rare species.
