People's Knowledge and Risk Perceptions of Invasive Plants in Metro Vancouver, British Columbia, Canada.

Effective management of invasive plants conserves biodiversity values, reduces economic costs, and minimizes negative impacts on human health. Fostering people's awareness of invasive plants is one of the most cost-effective approaches in preventing the spread and introduction of invasive plants. Therefore, this study aims to understand (1) people's knowledge and risk perceptions, (2) associations between risk perceptions and demographics, and (3) people's willingness to support current management strategies in the Metro Vancouver region, British Columbia, Canada. An online survey was carried out and received 356 responses across the region. We found that people's knowledge and risk perceptions of invasive plants were ecologically oriented. Older respondents perceived higher risks of invasive plants. Among respondents of the same age, annual income higher than $50,000 was associated with higher levels of risk perception. Respondents who had professional and/or recreational group memberships perceived higher economic risks. Respondents highly supported activities that they could take part in directly, such as community invasive pulls and native species planting. Overall, our findings aid managers in allocating appropriate funding or tailoring outreach efforts to different aspects of invasive plants as well as groups/communities where people's knowledge and risk perceptions of invasive plants are low.

Effects of law enforcement and community outreach on mammal diversity in a biodiversity hotspot.

Management activities such as law enforcement and community outreach are thought to affect conservation outcomes in protected areas, but their importance relative to intrinsic environmental characteristics of the parks and extrinsic human pressures surrounding the parks have not been explored. Furthermore, it is not clear which is more related to conservation outcomes-the management itself or local people's perceptions of the management. We measured objective (reports by park staff) and subjective (reports by local people) levels of community outreach and law enforcement based on responses to 374 questionnaires. We estimated mammal abundance and diversity of 6 protected areas based on data from 115 camera traps in Xishuangbanna, southwest China, a biodiversity hotspot with high hunting and land-conversion pressures. We then examined correlations among them and found that local people's perception of law enforcement was positively related to the local abundance of 2 large, hunted species, wild boar (Sus scrofa) (ß = 15.22) and muntjac (Muntiacus vaginalis) (ß = 14.82), but not related to the abundance of smaller mammals or to objective levels of enforcement. The subjective frequency of outreach by park staff to local communities (ß = 3.42) and park size (ß = 3.28) were significantly and positively related to mammal species richness, whereas elevation, human population density, and subjective frequency of law enforcement were not. We could not conclude that community outreach and law enforcement were directly causing increased mammal abundance and diversity. Nevertheless, the patterns we detected are some of the first empirical evidence consistent with the idea that biodiversity in protected areas may be more positively and strongly related to local perceptions of the intensity of park management than to either intrinsic (e.g., elevation, park size) or extrinsic (e.g., human population density) environmental factors.

Efectos de la Aplicación de la Ley y la Participación de la Comunidad sobre la Diversidad de Mamíferos en un Punto Caliente de Biodiversidad Resumen Las actividades de manejo como la aplicación de la ley y la participación de la comunidad afectan los resultados de conservación dentro de las áreas protegidas, pero su importancia en relación con las características ambientales intrínsecas de los parques y las presiones humanas extrínsecas que rodean a los parques no han sido exploradas. Además, no está claro cuál está más relacionado con los resultados de conservación - el manejo en sí o las percepciones que las personas locales tienen sobre el manejo. Medimos los niveles objetivos (reportes dados por el personal del parque) y subjetivos (reportes dados por los locales) de la participación de la comunidad y la aplicación de la ley con base en las respuestas a 347 cuestionarios. Estimamos la abundancia y diversidad de mamíferos de seis áreas protegidas con base en datos de 115 cámaras trampa en Xishuangbann, al suroeste de China, un punto caliente de biodiversidad con altas presiones causadas por la caza y la conversión del uso de suelo. Después examinamos la correlación entre ellos y encontramos que la percepción que los locales tienen sobre la aplicación de la ley estuvo relacionada positivamente con la abundancia local de dos grandes especies que son cazadas, el jabalí (Sus scrofa) (ß = 15.22) y el muntíaco (Muntiacus vaginalis) (ß = 14.82), pero no estuvo relacionada con la abundancia de mamíferos más pequeños o con los niveles objetivos de la aplicación de la ley. La frecuencia subjetiva del alcance del personal del parque hacia las comunidades locales (ß = 3.42) y el tamaño del parque and (ß = 3.28) estuvieron relacionadas significativa y positivamente con la riqueza de las especies de mamíferos, mientras que la elevación, la densidad de la población humana, y la frecuencia subjetiva de la aplicación de la ley no lo estuvieron. No pudimos concluir que la participación de la comunidad y la aplicación de la ley estuvieran causando directamente una abundancia y diversidad aumentada de mamíferos. Sin embargo, los patrones que detectamos son de las primeras evidencias empíricas consistentes con la idea de que la biodiversidad en las áreas protegidas podría estar relacionada positiva y fuertemente con la percepción que tienen los locales de la intensidad del manejo del parque y no con los factores ambientales intrínsecos (p. ej.: elevación, tamaño del parque) o extrínsecos (p.ej.: densidad de la población humana).

Public awareness of aesthetic and other forest values associated with sustainable forest management: a cross-cultural comparison among the public in four countries.

Korea, China, Japan and Canada are all members of the Montreal Process (MP). However, there has been little comparative research on the public awareness of forest values within the framework of Sustainable Forest Management, not only between Asia and Canada, but also among these three Asian countries. This is true of aesthetic values, especially as the MP framework has no indicator for aesthetic values. We conducted surveys to identify similarities and differences in the perceptions of various forest values, including aesthetic values, between residents of the four countries: university student groups in Korea, China, Japan and Canada, as well as a more detailed assessment of the attitudes of Koreans by including two additional groups, Korean office workers, and Koreans living in Canada. A multivariate analysis of variance test across the four university student groups revealed significant differences in the rating of six forest functions out of 31. However the same test across the three Korean groups indicated no significant differences indicating higher confidence in the generalizability of our university student comparisons. For the forest aesthetic values, an analysis of variance test showed no significant differences across all groups. The forest aesthetic value was rated 6.95 to 7.98 (out of 10.0) depending on the group and rated relatively highly among ten social values across all the groups. Thurstone scale rankings and relative distances of six major forest values indicated that climate change control was ranked as the highest priority and scenic beauty was ranked the lowest by all the groups. Comparison tests of the frequencies of preferred major forest values revealed no significant differences across the groups with the exception of the Japanese group. These results suggest that public awareness of aesthetic and other forest values are not clearly correlated with the cultural backgrounds of the individuals, and the Korean university students' awareness could potentially be representative of the Koreans general public's opinion. We expect this research to contribute to the development of aesthetic and social indicators, and to the enhancement of balancing social with environmental and economic values within the SFM framework.
