The image shows three rectangular landscape photographs arranged horizontally and labeled at the bottom of each panel as “(A)”, “(B)”, and “(C)”, illustrating changes in forest cover in Jasper National Park over time. Panel “(A)” on the left is a historical photograph from 1915 and shows a mountain valley with sparse forest cover, exposed slopes, and a river or valley corridor running through the center. Panel “(B)” in the middle is a repeat photograph from 1998 and shows the same valley with noticeably increased forest cover extending across the slopes and valley floor, while the mountains and corridor remain visible. Panel “(C)” on the right is a repeat photograph from 2019 and shows the same landscape in full color, with dense forest cover on the slopes and valley floor, green vegetation in the foreground, and distant mountains under a bright sky.Changes in forest cover in JNP (A: 1915 historical photograph, (b) 1998 repeat photograph, (c) 2019 repeat photograph).
