Claim Text:
1. An elongated terrestrial mollusc barrier for deterring terrestrial molluscs from entering a protected region, comprising: an elongated wall portion configured to extend from a surface along a length of a perimeter of a region to be protected; an attachment member configured to attach the elongated wall portion to a landscape barrier; a granular mollusc deterrent; an inverted channel defined by at least a portion of the wall portion and a downward depending barrier portion, wherein the inverted channel is configured to receive the granular mollusc deterrent, and wherein the downward depending barrier portion is configured to reduce liquid intrusion and dissolution of the granular mollusc deterrent; and a mesh retainer extending along at least a portion of the inverted channel, wherein the mesh retainer has aperture sizes corresponding to a size of the granular mollusc deterrent to retain the granular mollusc deterrent within an inverted dry chamber portion of the inverted channel, such that there is a path for a terrestrial mollusc to directly contact retained mollusc deterrent exposed through the mesh retainer and fall from the retained mollusc deterrent to the surface when the elongated wall portion is substantially vertical, and wherein the mesh retainer exposes at least some of the retained, granular mollusc deterrent along an inverted surface-facing opening of the inverted channel, such that the retained granular mollusc deterrent is configured to directly contact a terrestrial mollusc attempting to surmount the elongated barrier.
