New Acadia hiking trails foreman takes reins at key time
A new foreman is leading the way for work on Acadia hiking trails.
David Schlag, the new foreman of the Acadia trails crew, stands outside the crew’s trailer in Acadia National Park.
David Schlag, a 14-year veteran of the crew, is taking over as Acadia National Park trails crew foreman at a time when the park is facing some headwinds: trail damage from extreme weather events, increasing wear and tear on the trails with record crowds and a continuing shortage of seasonal workers.
Schlag will also oversee what could be one of the more transformational projects in years for Acadia hiking trails. The National Park Service is planning several trail extensions and a rehabilitation of the birch-lined Hemlock Path to make it more accessible, possibly with a boardwalk, as part of a more comprehensive effort to restore the Great Meadow.
This section of Hemlock Path with its birch trees is much photographed, and set for a major overhaul to improve drainage and accessibility as part of the restoration of Acadia’s Great Meadow. It’s one of the projects to be overseen by David Schlag, the new Acadia trails foreman.
Cross over to Bar Island at low tide in June and July, and soon you’ll discover fields of majestic purple, blue and pink lupine wildflowers of Acadia, beckoning to be admired and photographed.
Western lupine blooms in early June on Bar Island. The flower is popular with tourists who sometimes stop to pose for photos next to the purple, blue or pink flowers.
Squeezed along the edge of the fields stands a less showy plant – common milkweed – which could be missed if not for a sign calling this place a “Milkweed Habitat.”
These fields may be the site of a coming showdown between lupine and milkweed that could affect the fate of monarch butterflies in Acadia National Park.
As photogenic as the spiky tall flowers of the western lupine are, they are invasive non-native plants, threatening to crowd out the homelier milkweed critical to the lifecycle of the monarch, which recently became candidate for listing under the US Endangered Species Act. The faceoff between lupine and milkweed and the monarch could eventually come to a head on the island, just off the coast of Bar Harbor.
An effort by the National Park Service to protect the soon-to-be-endangered Monarch butterfly includes spreading seeds for milkweed on Bar Island and staking signs to inform the public.
“If the western lupine is encroaching on critical habitats in the park…it would be a very high priority to remove it,” said Amanda S. Pollock, Acadia public affairs officer, in an email. In years past, the park’s Invasive Plant Monitoring Team “removed lupines encroaching on a significant area of milkweed to protect habitat for the soon to be listed as endangered monarch butterfly.”
Pollock said the team has managed lupine encroaching on milkweed on Bar Island, Fernald Point, and a small area near Great Meadow Drive. She said the team has removed lupine on Bar Island “but only a section of the field, near the milkweed and the path.”
The park has not planted any mature milkweed, but resource managers have spread seed in areas where milkweed would likely grow well, including Bar Island, Pollock added.
Which plant’s tendency to spread will win out: Invasive western lupine, on the left, or the later-to-bloom milkweed on the right? Monarch butterflies exclusively lay their eggs on milkweed, as the developing caterpillars need the milkweed sap for chemical defense against predators. This scene played out on Bar Island in Acadia National Park in early July.
