Sea to Trees

During warm, wet nights in early spring, thousands of amphibians shake off their winter grogginess and take to the roads. Hardy small mammals scamper along the forest floor and make extensive homes within the cracks of Acadia’s mountains. Some of the park’s smallest creatures, that play outsized roles in nature’s food web, are also some of its most mysterious. Learn about two survey projects asking what it’s like to take the pulse of Acadia National Park on Season 3 Episode 3 of Sea to Trees.

In 1956, Robert MacArthur sat in a spruce-fir forest of Acadia National Park and tried to understand the truth behind warbler diversity. How could there be so many different species coexisting, when theory seeks to crown “one warbler to rule them all?” Learn about MacArthur’s study, how it changed the field of ecology, and the scientists revisiting his work over half a century later on Season 3 Episode 2 of Sea to Trees.

Tucked away on the University of Maine campus is a treasury of film that chronicles New England’s landscape from 1946 to 2015. We’ll hear from the researcher who is digitizing thousands of aerial photographs and making them accessible online. What can these photos tell us about the history of Acadia and how can they influence the future of land stewardship? Find out on the season three premiere of Sea to Trees.

In Season Three of Sea to Trees, we’re learning about research that delves into the past, seeks to understand the present, and charts the future of Acadia. We’ll walk through the same spruce forests as MacArthur’s warblers, try to understand how human activity is affecting some of the smallest creatures in the park, and illustrate the power of sea level rise with a group of young scientists. What can we learn from the past and present to help our future? www.Schoodicinstitute.org

Episode 3 begins with naturalist Laura Sebastianelli, who has dedicated her summers to recording all the bird songs in Acadia National Park. We follow Laura on her chase to record the American Bittern, learn why it’s so important to record Acadia’s birdsongs, and talk to all sorts of ornithological experts along the way.

Bird song is so much more than just bird-song. In this episode, we’ll learn all about birds, their songs, and what we can do to keep them around.

From social trails to heavy rain events, the summits in Acadia National Park are experiencing a lot of degradation. In this episode, we’ll discover how a backpack full of dirt can help bring life back to Acadia’s mountains. Schoodic Institute at Acadia National Park: https://schoodicinstitute.org/

Maya Pelletier calls rockweed, a type of seaweed, “the van Gogh of the intertidal.” How can citizen science help paint a picture of the state of rockweed on Maine’s coast?

In the 1880s, the Champlain Society documented the flora and fauna on the land that would become Acadia National Park. If the Champlain Society were around today, would they use iNaturalist?

The nation’s largest assessment of mercury contamination started as a project between scientists, teachers, and students at Acadia National Park. How has the help of more than 6,000 citizen scientists improved our understanding of mercury pollution across the US?
