Fig. 1 Net Changes in Cover . Changes in cover of species groups at the plot level with respect to pre-treatment values (2006) for each year (2007-2020). Points show the change in cover (i.e. ‘hits’) versus 2006 for a given plot by each species group within each year (n=6 plots per treatment x 4 groups x 14 years). Lines reflect modeled estimates of cover change by treatment type, species group, and duration of treatment (number of years since 2006) with a random effect of calendar year with 95% confidence intervals plotted around line estimates (Table 1).
