The Society for Northwestern Vertebrate Biology is the longest running scientific association devoted to the study of vertebrate ecology in the Pacific Northwest. Our society strives to promote professional working relationships among ornithologists, mammalogists, herpetologists, and ichthyologists in our region.

Please explore our website and be sure to check out our flagship publication, Northwestern Naturalist. If you share our passion for learning about the natural history and ecology of the Northwest consider attending our annual meeting, a great place to meet new people while learning about research that is currently being conducted in our region.
