Trees are a great tool for restoration—they store carbon, provide habitat for wildlife, and prevent erosion with their root systems.
But some types of trees hold a trick within their biology that makes them even more effective, a kind of shortcut that allows people to quickly fill an area with new plantings.
“Trees are expensive,” said Zach Cline, live stake coordinator with the Chesapeake Conservancy. “Live staking is a great way to get them really cheap, and plant hundreds of trees with only a few hours of time.”
Rather than planting a seed or a sapling in the soil, live staking involves taking a cutting of a branch or stem and driving it into the ground. Each stake—they must still be alive, hence “live” staking—will then grow roots and eventually become an individual tree.
Though there’s something almost magical to full trees sprouting from stakes, the process is a longstanding technique that takes advantage of reproductive strategies of trees in areas of high disturbance. Cline said that trees such as willows and dogwoods evolved to propagate not only from seeds but also with stems and branches that take root when they fall off a tree.
Live staking doesn’t work everywhere. It’s more successful with certain types of trees adapted to wetlands (willows, dogwoods, elderberry, buttonbush, alders, and sycamores) and in wetter areas where stakes can get a lot of moisture. Live stakes can be beneficial along streambanks, where they help against erosion, as well as for urban or agricultural areas.
With the right conditions, live staking can be very successful. Chesapeake Conservancy carries out live staking projects throughout the region, and they’ve had planting areas where 90 percent of stakes grow into trees, Cline said.
In March, the Maryland Department of Natural Resources hosted a live staking training event at Pearlstone Retreat Center, an environmental education center in Reisterstown, Baltimore County. The Chesapeake Conservancy led the training, which brought in staff and volunteers from several local organizations.
DNR and the Greater Baltimore Wilderness Coalition support a workforce development program called the Climate Crew Network. Emily Morrow, green jobs network coordinator with DNR’s Office of Outdoor Recreation, said these trainings are aimed at helping people gain skills for green jobs, but they also offer other benefits.
“Part of that workforce development is getting exposure to a lot of different environmental fields,” Morrow said. “So learning how to live stake might be environmental education and it might be community engagement, but it’s also showing people the value of being outside and why that’s good for your physical and mental health.”
At Pearlstone, the group geared up with pruners, loppers, and buckets, and descended a hill to a small impoundment pond. That day, the work of the trainees served a dual environmental purpose—as they gathered live stakes, they were also helping to clear cut an area where vegetation was impeding the function of the small dam.
When an area isn’t being clear cut, Cline said it’s best to take only a third of the mass of a tree or shrub. So if there are nine stems in the ground, take only three. That lets the trees easily grow back.
Using the loppers, the group cut off large stems of willows and dogwoods. Then, they pruned off smaller branches, so each stem became one long, straight stick. They placed the stick standing straight up in the 5-gallon bucket in order to cut it to about 1.5 feet, lopping a straight cut on the top and a diagonal cut on the bottom, where the stake will go into the ground. The stake should be about the width of a thumb…
