Arkansas Natural Heritage Commission
This is a great resource for Arkansas-specific information. ANHC’s professional staff conducts on-the-ground field surveys to locate and evaluate occurrences of natural communities and rare, threatened, and endangered species. Research findings and results are published in papers, professional presentations, and organized, analyzed, managed, and housed in the Arkansas Heritage Program biodiversity database. These field surveys and research projects have information on more than 900 rare species that can be used to evaluate the relative imperilment of native species and shared for environmental planning purposes.
