An example of assessing the relationship between a performance metric (e.g., the intercept) and vegetation characteristics (e.g., hardwood proportion) across ecoregions. a For large ecoregions (i.e., at least 30 individual 313-ha aggregates could be sampled) in all study areas, a given performance metric is calculated across a range of aggregate-levels (black solid lines). At a given aggregate-level (vertical dashed line), the performance metric is extracted across ecoregions (black points). Smaller ecoregions (gray lines) were excluded. b The performance metrics for those points (black points) are regressed against a vegetation characteristic (solid line)
