Community ash densities and economic impact potential of emerald ash borer ( Agrilus planipennis ) in four midwestern states

摘要: A survey of 586 community representatives with urban tree canopy responsibilities was conducted to provide data on ash density within four states in the Midwestern U.S., and examine potential economic losses should emerald borer (EAB) become established their communities. One hundred twenty-three responses were received from communities various sizes. Data represented 10.5% population Illinois, Indiana, Michigan, Wisconsin, 21% all surveyed. Assuming complete loss due EAB, landscape value for trees boundaries estimated be between USD $7.7 (median-based) $15 billion (mean-based). The cost remove those is somewhat smaller would $3 $5.8 billion. Replacing lost EAB 5 cm street, park, private plantings $2.7 $5.2 total surveyed, including losses, removals, replacements are $13.4 $26 costs per 1,000 residents four-state region $395,943 $769,687. rates estimates can utilized by begin developing contingency plans impact them.
