Abstract

Shelters for enhancing the growth of trees by protecting tree trunks from damaging sunlight. The shelters include a longitudinal tubular structure having a top edge and a bottom edge. The shelters includes a conduit extending from the top edge to the bottom edge of the shelter. The longitudinal tubular structure may be formed from a polymeric material including a pigment selected to block at least a portion of electromagnetic radiation. The polymeric material including the pigment blocks at least about 30% of electromagnetic radiation at any wavelength from about 200 nm to about 2500 nm.
