TY - JOUR T1 - Modeling Survival and Consequent Replacement Needs in A Street Tree Population JF - Arboriculture & Urban Forestry (AUF) JO - JOA SP - 251 LP - 255 DO - 10.48044/jauf.1979.061 VL - 5 IS - 11 AU - Norman A. Richards Y1 - 1979/11/01 UR - http://auf.isa-arbor.com/content/5/11/251.abstract N2 - The limitations of basing street tree replacement rates on the rate of recent tree removals are examined, using recent inventory data from Syracuse, New York. Survival models from available information on the city’s four major street tree species show that survival of recently planted trees dominates the rate of replacement needed to maintain the population, whereas the longevity of older trees has much less effect. Similarly, good care of developing young trees will reduce replacement needs more than will maintenance to prolong the life of older trees. ER -
