They, sometimes, come from Atlanta. Sometimes they volunteer from Alpharetta, or Roswell, or Gwinnett County.
This time, however, was a little different.
45 students from the University of Wisconsin-Madison are offering their services at the John Ripley Forbes Big Tree Preserve, in Sandy Springs.
To his knowledge this is the farthest anyone has traveled to volunteer at Big Trees.
"They want to spend a morning doing a service project," says Sam Hale, the preserves's president.
"They were looking, online, for some sort of community service project, and they found us," says Hale.
"We will be planting native plants at the Preserve," Hale tells WSB. "They're going to dig and plant those plants."
The students will be making three stops during their spring break; Champaign, Illinois, Nashville, Tennessee, and Sandy Springs.
The planting should take about three hours and then the volunteer will be on their way.
"I don't know where they're going after this," says Hale, "but we're grateful that they chose to come here."
