Figure 1. Photographs of control (forested) and gap (open) study sites on 8 May 2011.
Figure 3. Temperature (in degrees C, see colorbar on left) as a function of time and distance along the forest floor at a second-growth forest study site. Solid dark blue lines (0C) illustrate the presence of snow cover, which insulates the ground and prevents diurnal temperature fluctuations. Forest treatments are identified on the right, where both ‘Forest’ and ‘Control’ indicate untreated 80-yr old forest. While snow persisted longer in the gaps than the untreated and thinned forest plots, the variability between different gaps was more than one week.
