1 Introduction The once widespread native tallgrass prairies of the Great Plains have been largely eliminated by human actions. It is estimated that more than 90% of the native tallgrass prairies of North America, thought to have at one time covered 67.6 million ha, no longer exist (Samson and Knopf 1994). The decline of native prairies is largely attributable to their conversion to agricultural and other land uses (Samson et al. 2004).
1 INTRODUCTION Ecological communities and their properties (e.g. species richness, biomass) are temporally dynamic. Temporal variability tends to decrease with increasing spatial scales (e.g. local to regional) and with increasing levels of biological organization (e.g. population to community and ecosystem level) (Gonzalez et al., 2020; Kéfi et al., 2019; Tilman, 1996).
