Public perceptions of risk and acceptability of forest vegetation management alternatives in Ontario. Forestry Chronicle, 74, 720-727.https://hdl.handle.net/1794/220818 pagesWe examined public perceptions of risk and acceptability for 9 alternatives to controlling forest vegetation in Ontario (N = 2,301) in the fall of 1994. The proportion of respondents indicating whether an alternative was 1) difficult to control, 2) potentially catastrophic, 3) a problem for future generations, and 4) a personal worry determined perceptions of risk for each vegetation management alternative. Ranking of alternatives from highest to lowest perceived risk was: aerially-applied herbicides> biological control > ground-applied herbicides> mulches> prescribed fire> heavy equipment> cover cropping> manual cutting> grazing animals. Public acceptance was lowest for aerially-applied herbicides (18%) followed by ground-applied herbicides (37%), biological control (57% ), prescribed fire (57% ), mulches (65% ), heavy equipment (72%), cover cropping (80%), grazing animals (82% ), and manual cutting (89% ). Public acceptability of various agents for biological control differed depending on the proposed agent. Natural plant toxins were viewed as most acceptable (73%) followed by microorganims (42%), genetically-engineered organisms (39%), and viruses (21 %). We found a strong correlation between a risk perception index and acceptability of the alternatives for the general public (r2 = 0.84) and those in timber- dependent communities (r2 = 0.89). Our results suggest that stronger public support can probably be achieved for forest vegetation management programs that include non-herbicide alternatives.en-USCreative Commons BY-NC-ND 4.0-USForest vegetation managementPublic oppositionRisk perceptionHerbicidesBiological controlPrescribe fireMulchesHeavy equipmentCover croppingGrazing animalsManual cuttingArticle
