Hyperlocal collections invite individuals, families, communities, and organizations to a greater understanding of, and personal responsibility for, their local biotas. These collections document such things as a school or library campus, a park, a rural county, and similar. Fostering and deepening relationships between hyperlocal collections and biodiversity research professionals represents a critical opportunity for conservation. These collections represent potential pockets of very high quality biodiversity data, given the intense focus on one location, as well as mechanisms to change the ethical calculations that individuals and communities apply to biodiversity (what has been described as “biodiversity mainstreaming”). Join us to hear about examples of hyperlocal collections in several contexts (including a small arboretum, a high school, and a rural library) and to contribute to the conversation about the future of these important resources.
