Voyageurs jack pine hits a height jackpot

December 7, 2018

An old jack pine in northern Minnesota has become a national champion.

Few likely would know that it was special as they whiz by on snowmobiles along the Namakan Lake shoreline in Voyageurs National Park. But two biologists knew it was big so big that its the largest in the country and reigns as the national champion of jack pines on the American Forests champion trees register.

That now makes Minnesota home to four of the 783 national champions and co-champions on the register kept by the national conservation organization.

Truth be told, the champion jack pine kind of blends into the rest of the forest, with some of the red and white pines towering 20 feet or more above it.

It kind of looks like a bump in the tree line, said wildlife biologist Austin Homkes. But most jack pines look like bushes on a hilltop. They look like theyve been struck by lightning several times.

But for those who know jack pines, this one is almost majestic.

Homkes and fellow biologist Tom Gable are always on the lookout for big trees as they traipse through the woods, tracking GPS-collared wolves.

It was Homkes who first spotted the jack pine in summer 2017. But without his measuring tools, he couldnt tell how large it was. When winter set in, Homkes and Gable were back in the area and tromped about 50 meters into the woods to take a look.

Thats enormous for a jack pine, Gable immediately blurted out to Homkes. When I saw its big trunk, I knew it was a record.

Sure enough. When all the measuring and verifying by state tree experts was done, it hit the jackpot of jack pines, standing at 73 feet high with a trunk measuring nearly 7 feet around.

That may seem puny compared to the 122-foot-tall national champion red pine in Michigan or the 138-foot-tall champion western white pine in Nevada. But by nature, jack pines are scrawnier than the more majestic reds and whites.

They often look battered and worn, Gable said. It looks like theyve taken on the elements over the years and grown up scraggly.

Few people would take notice of such trees or others, but Gable and Homkes are on a mission to find the big ones. Theyve measured and documented 200 of them.

Theyre not all champions, obviously, Gable said. But three, including the jack pine, are state records. They include a black spruce in a bog off the Ash River Trail in Voyageurs National Park and a balsam fir in Vogageurs on Kabetogama Lake.

If you dont know what youre looking for or not looking at all, you can easily pass by a tree over and over and have no idea its big, Gable said.

Few people, however, get as deep into the woods as Homkes, Gable and the other researchers working on the Voyageurs Wolf Project, a collaborative effort between the park and the University of Minnesota to study the ecology of the wolves and their prey.

Since 2015, the research teams have logged about 5,000 miles in the back country, said Steve Windels, wildlife biologist at the park. Gable and Homkes are bushwhacking into places most people dont go, and they notice things that others without a trained eye wouldnt, he added.

When you think about these big trees, theyre hiding in plain sight, Windels said. There are millions of trees here and probably lots of big ones but you probably just walk past them.

Gable and Homkes dont. They constantly scan the tree canopy as they tromp through the woods and scour the horizon from rock ledges.

We have an awareness of what could be out there, Gable said. People could see the exact same thing and not understand the significance.

The two cant help but be fascinated by the idea that trees germinated a hundred or more years ago are still standing, growing through the decades when caribou and moose were plentiful in northern Minnesota.

It symbolizes untouched wilderness, Gable said. Theres something about seeing these old trees that takes you back in time and makes me contemplate how much things have changed since then.
