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.
