Some outdoor recreation activities are regulated and require participants to have a permit or license (e.g., hunting and fishing). However, wildlife watching—and especially birdwatching—is a non-consumptive activity that requires no permit or license and thus leaves few formal data trails. Crowd-sourced data with associated volunteered geographic information, gathered by a variety of citizen/community science projects and social media platforms, can complement the information about non-consumptive activities provided by standard administrative datasets.
