From: Vegetation Response to Burn Severity, Native Grass Seeding, and Salvage Logging
Species richness (number of species, top) and Shannon-Wiener (SW) diversity index (bottom) for all severity and seeding treatment combinations. Data are contrasted by not salvage logged (left) and salvage logged (right). Error bars represent standard error. Capital letters next to the years on the x-axis and next to the treatments in the legend represent significant differences between means by year or by treatment; legend items are ordered from highest to lowest mean value over all years
