Invasive species control or eradication is an important issue. On the islands of Hawaii, this problem is exceedingly evident
when it comes to Miconia
calvescens (Miconia). Adequate funding is needed to control or eradicate this invasive plant, but with the limited amount of funding available
for the fight against Miconia, it is important to make sure that the fund is being spent in a way that addresses the needs or preferences of the Hawaiian
residents. Using the conjoint choice experiment method, we designed a survey that would measure the Hawaiian residents’ willingness
to support Miconia control program attributes. The attributes focused on were cost, biodiversity loss, extent of spread and soil erosion. Latent
class approach was used to assess the surveyed population to see the different preferences by individual classes. The results
show three different classes or groups of individuals with varying preferences for a control program of which cost and erosion
were the top preferred attributes among the classes. These groups were defined by their socio-demographics of income, the
length of residency and exposure to farming/gardening activities. Even with a preference for lower cost, a group showed willingness
to pay more ($2.40) for a program that reduces erosion from high to low. Finally, the biodiversity attribute had very low
consideration from a majority of the respondents showing the need for educating the public regarding its importance in preserving
the unique environment in Hawaii. 相似文献
