Claim Text:
1. A beaver control device for use with a culvert pipe comprising: a cylindrical frame comprising a plurality of longitudinally extending bars at angularly spaced positions around a longitudinal axis of the cylindrical frame and at least one peripheral bar arrangement interconnecting the longitudinal bars so as to define on the frame a longitudinal length between opposing longitudinal ends thereof, a bottom peripheral portion for resting on the ground, a to peripheral portion which is vertically opposite the bottom peripheral portion, a transverse center plane passing across the frame through the longitudinal axis and an upright center plane passing through the axis joining the bottom peripheral portion and the top peripheral portion; and a plurality of transverse bars generally parallel to the transverse center plane; the plurality of transverse bars being arranged at positions spaced along said longitudinal length of the frame; each of the transverse bars spanning substantially straight across the frame from a position at or adjacent the frame on a first side of the upright center plane to a position at or adjacent the frame on second opposite side of the upright center plane; wherein the plurality of transverse bars are elevated above the bottom peripheral portion of the frame and located at a position below the transverse center plane so that the transverse bars are closer to the bottom peripheral portion than to the top peripheral portion.
