Gallery: 2024 Spring Salamander Survey
We welcomed two dozen volunteers out to Emily Min Hunt Preserve April 27 to explore the protected property and assist in Huron Pines’ annual Spring Salamander Survey.
This opportunity in community science is one way our organization assesses and monitors the health of the preserve’s ecosystems, particularly the sensitive forest wetlands where amphibians like salamanders and wood frogs congregate during the spring breeding season. Emily Min Hunt Preserve is located in southeastern Presque Isle County.
Weeks ahead of time, our team placed a series of cover boards—small squares of untreated plywood and thin slabs of natural logs—in a grid pattern on the forest floor. These objects are an ideal spot for salamanders to hide or hunt for insects and a safe place for volunteers to collect these reclusive creatures in a methodical way.
When one is found, volunteers swiftly and carefully contain individual salamanders in sandwich bags to minimize handling while measurements are taken. Working in teams, volunteers note the length and species of each individual and where it was located within the grid, providing useful data on the age and density of the salamander population in this corner of the preserve.
Just as importantly, the survey is a way for people to make deeper connections to nature and become better stewards of the unique wildlife and landscapes which define Northern Michigan. For some, it’s their first time seeing a salamander, and other discoveries—like a ring-necked snake coiled under a cover board—are always possible.
June Baer, age 8, giggled with delight while holding a spotted salamander for her first time, describing the experience as “scary but really cool actually.”
“I saw this (event) on the news and knew she’d enjoy it,” said June’s dad, Sam. “She loves animals and learning and is so curious about everything."
We found 16 salamanders that morning—14 eastern red-backed salamanders, a common variety, and two spotted salamanders which marked the first appearance by this species in our surveys. The abundance and diversity of these creatures are a sign this protected ecosystem is in good health.
Thank you to all the volunteers who joined us for this year’s survey, and to the Consumers Energy Foundation for supporting the event. We've gathered some photos from the survey which you can find in the gallery below.
2024 Survey Results
Sixteen salamanders representing two species were found during the 2024 survey. The graphic below illustrates the grid layout of salamander cover boards and natural wood slabs near a forested wetland at Emily Min Hunt Preserve. Here’s how to interpret the illustration:
This is a view looking down onto the grid covering an area of approximately 6,750 square feet.
Letter/number combinations (example “E2”) denote sites with a board and a natural wood slab. Each site has a board and a wood slab adjacent to one another.
Colored squares indicate sites where salamanders were found.
A blue square (“E1”) indicates a site where at least one salamander was found under the board.
A pink square (“B5”) indicates a site where at least one salamander was found under the wood slab.
A purple square (“A5”) indicates a site where salamanders were found under both the board and the wood slab.
Salamanders appear to favor the plywood boards, which may trap and hold more moisture against the ground.
2023 Survey Results
The graphic below illustrates the grid layout of only plywood cover boards at the preserve for the 2023 survey. Natural wood slabs were added for the 2024 survey to better understand the preferences of salamanders. Seven salamanders were found during the 2023 survey and their locations are indicated by the pink squares.
