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.

The present invention relates to the field of robot intelligent control technology, and in particular to a navigation path control method for a beaver-like robot using multimodal sensor fusion. The method comprises: collecting underwater environment data and motion posture data of the beaver-like robot in real time through a multimodal sensor group; preprocessing the underwater environment data and the motion posture data of the beaver-like robot; and generating a global navigation path based on a dynamic model of the underwater environment using an improved path planning algorithm. The present invention uses multimodal sensor fusion technology to integrate multiple sensors such as sonar, binocular vision cameras, depth sensors, and inertial measurement units to achieve comprehensive collection of underwater environment and motion posture data of the beaver-like robot, effectively solving the problem of incomplete perception of traditional single sensors, greatly improving the obstacle detection rate, significantly improving the accuracy of environmental perception, and improving the navigation efficiency and safety of the beaver-like robot in complex underwater environments.

A method of extracting water-soluble minerals from an arid location includes identifying or establishing a channel of flowing water at the arid location, and installing a mat containing seeds, and / or seedlings, and a super absorbent polymer (SAP). A perforated, transparent cover sheet is placed on or above the mat. Water is applied to the SAP, such that both edible and dam-constructing vegetation grows and matures from the mat. Beavers are introduced into the arid location, which eat the edible vegetation and use the dam-constructing vegetation to construct a dam that blocks the channel, thereby flooding a region proximate the channel. After the flood water has dissolved the minerals in the flooded region, it is drained and processed to extract the minerals. The drained water can be remotely processed, or directed to an evaporation pond, where the minerals remain while the water is evaporated, recaptured, and reintroduced into the channel.

A culvert has an attachment at an entrance end for inhibiting beaver activity at the culvert where the attachment includes two panels coupled together at one end by a third panel portion or by a hinge to form a pivotal structure with each panel including a bottom rail placed on a ground surface extending from the culvert entrance and a plurality of upstanding bars at spaced positions along the bottom rail. The attachment is opened at the hinge line or the third panel portion so that the hinge line is located in front of the entrance with each panel extending back to a respective side of the entrance and fastened by a chain coupling to that side. The upstanding bars are arranged so that water passes therebetween to or from the entrance end and the bars are closely spaced so as to prevent passage of beavers to the entrance end.
