Abstract. Foliar cover is often selected over biomass as the variable to sample when inventory- ing agroforestry systems. To assess forage production, biomass and cover must be satisfac- torily correlated. Significant cover/biomass relationships were developed for four major Alabama forest types. Conversion factors varied by forest type. These relationships provide practical application of understory cover measurements taken in forest inventories for use in multiresource assessments and in designing agroforestry systems.
