Regional differences in farmers' preferences for a native bee conservation policy: The case of farming communities in Northern and Eastern Thailand.

Evidence points to past bee-mediated crop pollination deficits in Chanthaburi province, Eastern Thailand. Conversely, no such evidence has yet been reported for Chiang Mai province (Northern Thailand), suggesting that wild pollination is delivered there above the requirements of local orchards. Disc...
