[email protected] 1 Supplemental Methods Study site Our study took place in three sites (named Helena, Paradise, and Whitefish) within the Northern Rocky Mountains, which encompasses the Crown of the Continent and the Greater Yellowstone Ecosystem in western Montana, USA (Fig. 1; Burkle, Myers, & Belote, 2015). Historically, this region has experienced mixed-severity fire regimes (Baker, 2009; Fischer & Bradley, 1987), which favor understory and early successional plant species and a mosaic of forest successional stages (Hessburg & Agee, 2003; Perry et al., 2011). Wildfires have largely been suppressed over the past century, however, leading to denser stands and more intense and extensive wildfires in the past few decades (e.g. Miller, Safford, Crimmins, & Thode, 2009). The Helena site is characterized by low primary productivity, Paradise by intermediate productivity, and Whitefish by high productivity (Burkle et al., 2015). These three site include a variety of forested ecosystems, including ponderosa-pine dominated forests and woodlands in Helena, lodgepole- pine and Douglas-fir forests in Paradise, and western-larch, lodgepole-pine and mixed-conifer forests in Whitefish (Burkle et al., 2015).
