Unintended Consequences
Some unintended consequences have been observed from post fire seeding. Seed mixes, even “certified weed free” seed mixes, have been contaminated with invasive species and initiated new infestations. Successful growth of seeded grasses (i.e., enough to affect water erosion) have displaced native or naturalized species, including shrub and tree seedlings. Seed bed preparation and the seeding process has facilitated the growth and expansion of naturalized non-native species. The machinery used in landscape seeding operations (e.g., drill seeders and chains) impact surviving native plants and disturb microbial soil crusts.
