The resulting deformation, growth loss and mortality negatively affect forest health, ecosystem functioning, biodiversity, and social and economic values. Invasive species, specifically invasive plants, can interfere with forest regeneration and productivity through direct competition with tree seedlings, resulting in reduced density and slowed growth rate of tree saplings.
