The effects of native seed mix composition and sowing density on plant community reassembly in wetlands

Seed-based restoration of wetlands is often necessary to improve important ecosystem functions (e.g., invasion resistance, habitat-provisioning) and meet society’s need for wetland ecosystem services such as supporting recreational activities and improving water quality.  However, persistent questions remain about the composition and sowing density of seed mixes needed to restore robust native wetland plant communities.  In Great Salt Lake wetlands (Utah, USA), the revegetation of native species is crucial to recovering critical habitat and preventing reinvasion of the invasive, non-native grass, Phragmites australis and other invasive species (e.g., Typha spp.).  In greenhouse and field experiments, we investigated the effects of seed mix composition and sowing density on plant community reassembly.  We predicted that seed mixes containing native forb species with resource-preempting traits (e.g., rapid seedling emergence, high aboveground growth rate), and high sowing densities (>5..., See article \"The effects of native seed mix composition and sowing density on plant community reassembly in wetlands\" for methods., , # Data from: The effects of native seed mix composition and sowing density on plant community reassembly in wetlands
