Abstract:
INTRODUCTION

Treeshelters are now used in the establishment of trees in the landscape (Evans and Potter, 1985; Frearson and Weiss, 1987; Potter, 1988). These treeshelters are cylindrical or square, translucent, polypropylene tubes of varying height (usually 60 to 150 cm) which are placed around seedlings or transplants at planting time. Trials in England have shown that placing these shelters over transplanted or naturally sprouted seedlings of various species improved the seedling survival rate. Treeshelters protected seedlings from herbicidal drift and animal browsing, but their most attractive characteristic was the 60% to 600% increase in plant height (Frearson and Weiss, 1987; Potter, 1988, 1991). Growth rate increases have been attributed to the enhanced growing environment around the plant achieved with the use of the treeshelter. Increases in ambient temperature, relative humidity, and CO₂ concentration have all been suggested as probable causes for increased growth
