Examples of whitebark pine trees encroaching into sagebrush grasslands for the three sites sampled during the 2017 and 2018 field seasons in southwest Montana, USA. (a) Morrison site: edge of mature seed-source stand showing whitebark pine encroachment into sagebrush landscape. (b) Morrison site: mature cone-bearing whitebark pine interspersed on sagebrush habitat. (c) Site in southwestern Montana: downward encroachment of whitebark pine into open sagebrush. (d) Morrison site: seedling- and sapling-sized whitebark pine mixing in with sagebrush. Photo credit: Sarah Flanary
