Rosemont retained WestLand Resources to conduct a variety of biological studies to support special status species, such as the federally listed lesser long-nosed bat. The Palmer's agave has been identified as the primary foraging plant for the nectar-feeding lesser long-nosed bat in southeastern AZ. WestLand conducted various surveys on the Property and regionally to determine how many agaves might be impacted by the proposed activities at Rosemont.
