发明名称 Shelter for trees
摘要 A tree shelter comprises two parts joined by clips along a longitudinal axis. Each part comprises a funnel portion and a base portion. Each funnel portion is formed to allow the shelter to mimick the natural bending of a tree stem under the action of wind and is contoured internally to increase the area available for condenstation and evaporation of moisture. Each base part is formed to restrict growth of weed around the base of the sheltered tree. The shelter acts to protect the tree whilst permitting its natural growth in its early years.
