Figure 24. Baseline risk of extirpation for the Tennessee Clubshell ( Pleurobema oviforme ) and Tennessee Pigtoe ( Pleuronaia barnesiana ) mussels in the Tennessee and Cumberland River Basins, including watersheds in North Carolina. Left panels (A and C) show the mean probability of being classified as extirpated and right panels (B and D) show the mean probability of being classified as extirpated or low condition for each watershed. Warm colors (reds) represent probabilities that are more likely than not (probability > 0.5) and cool colors (blues) represent probabilities that are less likely than not (probability < 0.5). Modified from USFWS (2020).
