Abstract

In 2002, the Hayman Fire burned across 55 800 ha of Colorado Front Range P. ponderosa-P. menziesii forest. Also burned in the fire were 20 upland and five riparian plots within a 400-ha study area. These plots had been surveyed for understorey plant composition and cover 5-6 yrs prior. We re-measured all plots annually from 2003 to 2007, 1-5 yrs post-fire. Changes in the occurrence of common understorey plant species and in metrics of understorey plant richness and cover were analysed with regard to fire severity and time since fire using repeated measures ANOVA. Compositional changes were explored using ordination.
