 To accomplish this, research must be done to determine best planting and propagation practices for the site.Research has been done on two fire resilient species- Santa Barbara sedge (Carex barbarae) and creeping wild rye (Leymus triticoides) regarding planting densities, which showed that the low-density plantings were more cost effective and that these plants survive better when planted separately.Ongoing research of understory vegetation working as an umbrella species and companion planting is underway.
