Dr. Andrea Lloyd says:

We're planting seedlings up here in a burned plot. This is a site that was burned about 8 years ago. And right now we're up above treeline. And what we're doing is going to 8 different places above treeline where there's a fire margin. So where we can find both burned and unburned sites. And at each of those 8 places, we're planting groups of 10 seedlings. And then we'll go down to treeline and do the same thing down at treeline where there's a fire margin as well. And what we're trying to learn from all this is what effect fire has on spruce regeneration at and above treeline.
