Vermont Atlas of Life

BREAKING NEWS! A vastly expanded web site coming in just days! Check back often for an amazing new site full of biodiversity information.


What lives here? Where is it? What’s common? What’s at risk? The answers lie scattered among books, reports, computers, museums and even the memories or journals of Vermonters now living or long passed. The average department store knows more about its inventory than we know about what lives in Vermont. In the information age, this is troubling.

As human activity profoundly alters the map of life on local and global scales, our response requires knowledge of plant and animal distributions across vast landscapes and over long periods of time. Vermonters cannot respond effectively to climate change, natural disasters, invasive species, and other environmental threats without a new understanding of the state’s living resources. At stake is nothing less than the health of our natural world, economy, and human life itself.

It started with a simple question. How many species occur in Vermont? You’d think we’d know this for a small state steeped in a rich tradition of naturalists going back to Zadock Thompson’s seminal work on the natural history of Vermont in 1842. But, the simple answer was, no one really knew.

We do know how many species there are of some of the popular taxonomic groups like birds (currently 382) or mammals (58). But how many invertebrates are there in Vermont? A back of the envelope estimate puts it at just over 21,400 species! There are about 2,150 species of plants, with approximately 1,400 native plants. We share Vermont with at least 26,000 species, although no one knows for sure just how many.

The list continues to grow as we discover new native and introduced species across the state. For example, citizen naturalists helped the Vermont Butterfly Survey (2002-2007) discover 12 new butterflies in the state and create a conservation watch list based on our newfound knowledge. We don’t have to go far to discover new and amazing species. In 2012, a plant new to science was discovered in the Green Mountains.

The mission of the Vermont Atlas of Life is to bring over 150 years of accumulated knowledge of the biodiversity of Vermont into currency for science and society. Imagine a biodiversity warehouse where all of this was gathered and shared. Where students could learn, citizen naturalists and professional biologists could contribute new information, and conservationists could use the latest information to help protect and manage Vermont’s natural heritage. A place where anyone, anywhere, anytime, could explore, learn and share Vermont’s unique biodiversity. We hope you’ll join our efforts.

Vermont eBird

A real-time, online checklist program, Vermont eBird has revolutionized the way that the birding community reports and accesses information about birds. Launched in 2003, a simple and intuitive web-interface engages thousands of participants to submit their observations or view results via interactive queries into the eBird database.

A real-time, online checklist and photo storage program, e-Butterfly is providing a new way for the butterfly community to report, organize and access information about butterflies in North America. Launched in 2011, e-Butterfly provides rich data sources for basic information on butterfly abundance, distribution, and phenology at a variety of spatial and temporal scales across North America.

Vermont Butterfly Survey

From 2002 - 2007 volunteers of all kinds searched fields and fens, mountains and meadows, even their own backyards, to document the status of Vermont butterflies. Despite their lofty status among the insects, butterflies were largely a mystery in Vermont. There was no atlas of their distribution, no scientific assessment of the threats they face, and no conservation concept for butterfly species on a statewide scale. With this in mind, we initiated the VBS. Visit the VBS site »

Vermont Breeding Bird Atlas

VBBA is the most comprehensive bird survey in the state, and occurs only once every 25 years. The first Atlas in Vermont was published in 1985. From 2003 to 2007, volunteers from every corner of the state surveyed Vermont, from forests and fields to valleys and mountains, keeping record of the birds they found. Visit the VBBA site »
