The Bigscale Logperch (Percina macrolepida) is a small (9 cm [3.5 in]) fish that is native to the Sabine River (Louisiana), Red River (Arkansas and Oklahoma), and the Rio Grande drainage (New Mexico, Texas, and Mexico). It has also been introduced in northeastern New Mexico. It inhabits runs and pools of small to medium rivers and can tolerate turbidity and a variety of flow levels; it is found in some reservoirs. The Bigscale Logperch will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Bigscale Logperch’s climate change vulnerability is primarily impacted by anthropogenic or topographic barriers and biologic factors that could increase the effects of climate change on this species.
