In highly fragmented landscapes, natural recolonization isn’t sufficient for restoring native plant communities. Obtaining sufficient quantities of native seed is a major barrier to many restorations, especially large-scale projects Wild seed harvest is relied on to overcome commercial seed supply constraints but it introduces risks to the remnant vegetation being harvested. In a field survey of harvested and unharvested tallgrass prairies, Justin Meissen (2015) showed that short-lived, non-clonal species appeared to be most susceptible to decline from seed harvest. His dissertation research followed up on this finding with modeling and field experiments.
