A method of creating a wetland in a remote arid location includes identifying or establishing a channel of flowing water at the arid location, and installing therein a mat containing seeds, and / or seedlings, and a super absorbent polymer (SAP). Water is applied to the SAP, such that both edible and dam-constructing vegetation grows and matures from the mat. Beavers are then dropped into the arid location by parachute in containers that open upon landing. The beavers eat the edible vegetation and use the dam-constructing vegetation to construct at least one dam across the channel of flowing water, thereby forming a wetland that further encourages both the vegetation and the beavers to propagate. A perforated, transparent or translucent cover sheet can be placed on or suspended above the mat. A water barrier can be placed below the mat. The wetland vegetation cools and humidifies the environment by transpiration of water.
