Glacier Park hen monitoring a part of continent-wide collaboration


Gear in hand, the group units off by way of the eerily silent forest of Glacier Nationwide Park nicely earlier than daybreak.

Because the solar’s first rays creep their means over the mountains to the east, greater than a dozen biologists, volunteers and interns are onerous at work establishing a sequence of huge nets alongside the mist-covered shore of McDonald Creek.

Their intention for the day is a straightforward one, seize as many birds as doable for identification, information assortment and banding.

The trouble is a part of the Institute for Chicken Populations’ Monitoring Avian Productiveness and Survivorship (MAPS) program, a continent-wide collaborative effort amongst public companies, non-governmental teams, and people to help the conservation of birds and their habitats.

Every summer time since 2020, park biologist Lisa Bate and her colleagues have arrange the nets and data-collection station each 10 days to study extra about Glacier’s hen inhabitants.

“We do that so we are able to examine the causes of hen inhabitants modifications in North America,” she defined. “We’re actually seeking to get at what are the causes for inhabitants decline or will increase and whether or not issues are extra severe in winter or breeding grounds. We need to see the traits in several areas and what are the relationships between inhabitants modifications and modifications in climate, local weather and habitat loss.”

MAPS hen banders acquire information that can be utilized to estimate key demographic parameters, often known as very important charges, like productiveness, recruitment, and survival of particular person hen species. This info helps scientists perceive which life-stages could also be most vital in limiting inhabitants progress or inflicting declines.

Since 1989, greater than 1,200 MAPS stations unfold throughout almost each state and Canadian province have collected greater than 2.5 million hen seize information.

Bate first heard about this system whereas taking part in a webinar and determined Glacier Nationwide Park can be an ideal place for a knowledge assortment station.

“Nationwide parks are nice locations to get management information on hen species since they don’t have growth, logging or mineral mining. Gathering information in a nationwide park can actually inform us quite a bit about what’s going on with sure species.”

In accordance with Bate, Yosemite Nationwide Park in California has seven information assortment stations and has been taking part in this system for greater than 20 years. She hopes Glacier can develop its program in coming years to assist acquire as a lot information as doable.

“We might band a hen right here and it might present up within the southern U.S., Mexico and even Central America and we are able to study the place it’s molting, the place it’s wintering and the way issues like local weather change are affecting that,” she stated. “That is information that could be very helpful to biologists.”

In its first three years of operation, the Glacier Nationwide Park MAPS station has captured or noticed greater than 75 species of birds within the park, however Bate says this system has different upsides as nicely.

“All the workers, volunteers, interns and guests with this system get to study hen IDs and we speak about hen conservation. I simply love seeing folks mild up when they’re holding a hen of their arms for the primary time,” she stated. “I additionally really feel strongly about getting younger folks out within the outdoor and extra engaged in wildlife conservation. I feel this is without doubt one of the greatest applications we’ve to get folks . It’s an effective way to mild a hearth beneath the subsequent technology of biologists and scientists.”

This system has already overcome quite a few challenges in its first three years, however Bate says it will likely be a couple of extra seasons earlier than scientists can glean any patterns from the information collected.

“You have to run a MAPS station for no less than 5 years to have the ability to see the traits within the information, so we’re nonetheless studying about what is occurring with the hen inhabitants in Glacier Nationwide Park,” she stated. “With us although, it’d take longer than that since we began in a 12 months with Covid after which the subsequent 12 months had flooding. Typically science takes a short time.”
