Table 1 Forest structural variables (diameter at breast height [dbh], basal area, height, and density) of live and standing dead (snags) trees, canopy cover, and understory visibility (Under vis) at the unburned reference site (R), close-burned site (QC), and distant-burned site (QL), measured between December 2015 to August 2017 at the piedmont Southern Andean Yungas forest, Jujuy province, Argentina. Values indicate mean ± standard deviation; same letter (a, b, c) next to the values denotes no significant difference (P ≥ 0.05)
