From: Prescribed fire limits wildfire severity without altering ecological importance for birds
Box plots depicting distributions of composite burn index (CBI) values for survey points treated by prescribed fire and burned by wildfire. Wildfire CBIs are shown separately for units previously treated versus not treated with prescribed fire. Boxes delineate the 25th, 50th, and 75th percentiles; whiskers denote the distance to observations furthest from the nearest quartiles (i.e., 25th and 75th percentiles) that are also within 1.5 × the inter-quartile range from the nearest quartile; and dots are observations further than 1.5 × the inter-quartile range from the nearest quartile
