WATER LOSS, NOT BRINE, KILLS MAPLE TREES

RESEARCH CONDUCTED AT THE UNIVERSITY OF MASSACHUSETTS SUGGESTS THAT DEICING SALTS AND AUTO EXHAUST EMISSIONS HAVE LITTLE TO DO WITH THE DECLINE OF MAPLE TREES IN THE VICINITY OF HIGHWAYS. RATHER, THE HIGHWAY INTRODUCES A NEW ENVIRONMENT WHOSE CHARACTERISTICS MAY BE DETRIMENTAL TO THE MAPLE AND OTHER BROADLEAF TREES AND SHRUBS. AMONG THE CONSTITUENTS OF THE TREE IN THE HIGHWAY ENVIRONMENT ARE SOIL MOISTURE, AIR FLOW, SOIL TEMPERATURE, SUNLIGHT RATINGS, SOIL DENSITY, AND RELATIVE HUMIDITY. IN SUM, THESE FACTORS LEAD TO EVAPOTRANSPIRATION: TREES AT THE ROADSIDE LOSE THREE TIMES AS MUCH WATER AS TREES IN THE FOREST. IN TESTS, DEICING SALTS DID NOT SERIOUSLY AFFECT TREES WITH A GOOD OVERALL ENVIRONMENT BUT DID IMPAIR THOSE IN A LESS FAVORABLE SETTING.
