Pyrodiversity Trait Covariance
While FDis accounts for redundancy among traits (Laliberté & Legendre 2010), understanding how fire traits covary is valuable for categorizing fire regime groups, as well as assessing the mechanisms by which variation in fire traits affects ecosystem pattern and process. We calculated correlations among the four pyrodiversity traits at the watershed scale. To test whether correlations varied with the amount of recorded fire history, we systematically filtered out less frequently burned watersheds with increasing higher thresholds of number of fires recorded. Specifically, correlations were made among traits for all study watersheds with minimum number of fires ranging from zero to fifteen.
