Vaccinium angiislifoliwn extends from ca. sea level to 1300 m asl in Eastern Canada to 1300-1500 m asl in Virginia. On the higher points of the Adirondack Mountains V. angustifolium is replaced by V. boreale (Sweet Hurts) (Vander Kloet 1977). 4. Physical Habitat (a) Climatic relations. Vaccinium angustifolium occurs in a large area of eastern North America and tolerates a wide range of climatic conditions. The variability of this species with regard to productivity is well established (Aalders and Hall 1963b; Hall, Aalders, and Wood 1966) but the adaptiveness of the species to different climatic conditions requires further study. A comparison of growth under different climatic conditions was conducted on uniform plant and soil media in 1965 and 1966 at Kentville, Nova Scotia; Normandin. Quebec; and St. John's West, Newfoundland. Linear shoot growth of 20 plants from seven clones at the three respective stations averaged 183, 141, and 111 cm per plant in 1965; and 195, 153, and 70 cm in 1966. The number of flower buds produced per plant averaged 126, 94, and 66 in 1965; and 88, 54, and 23 in 1966. Thus climatic conditions for growth varied widely among the three stations. Vegetative growth was not notably different between 1965 and 1966 at Kentville and Normandin, but much poorer in 1966 at St. John's West; reproductive growth was much better in 1965 than 1966 at all three stations. In Eastern Canada, winter temperatures for V. angustifolium and other chamaephytes are generally ameliorated by a snow cover. Inadequate snow cover may be followed by shoot dieback to ground level in the Lac de St. Je
