Cost-Benefit analysis for Dutch elm disease (Ophiostoma ulmi) in Manitoba, Canada
A cost-benefit analysis of Manitoba's integrated Dutch elm disease management programme, between 1975-90, has been carried out in Canada. Since 1981 Manitoban authorities spent an average of 1.5 million CAD per year to keep the disease incidence under 2.5%. An increase of the annual loss rate by a few percentage points would translate directly into costs of 22.3 million CAD for elm removal, 21 million CAD for replacement trees, a decline in real estate value and a near complete loss of the urban forests in many towns and cities. The province of Manitoba has realized a minimum of savings of 5.01 million CAD since 1981 by managing Dutch elm disease. Implementation of buffer zones around selected communities has significantly reduced urban elm losses.
