Fire & fitness of EA

Description: This recruitment experiment quantifies seedling emergence and juvenile survival of Echinacea angustifolia during its reintroduction to previously agricultural sites. We evaluate effects of two types of extant vegetation (restoration vs. old-field) on recruitment and effects of prescribed burning at four times relative to sowing. Seedlings, basal plants, and flowering plants were counted annually from 2001-2014. For 2015 and future years flowering plants are mapped as part of the demographic census in remnants experiment.
