squirrel corn |
Dicentra canadensis |
An inhabitant of the eastern hardwood forest, Dicentra canadensis seems to prefer rich soils with rocky outcrops. The deep ravines and river valleys of Minnesota's southeast counties represent the extreme northwest extent of Squirrel Corn's North American range. It is by no means common in that area. The DNR says it is now most at risk from invasive species, earthworms in particular, and was listed as a Special Concern species in 1984.? |

prescribed fire |
|
A helicopter, loaded with a DAID (Delayed Aerial Ignition Device) fuels up before taking off again during a prescribed burn. The DAID works by using polystyrene balls, 1.25 inches in diameter, containing potassium permanganate. The balls are fed into a dispenser, generally mounted in a helicopter as is the case here, where they are injected with a water-glycol solution and then dropped through a chute leading out of the helicopter. The chemicals react thermally and ignite in 25-30 seconds. The space between ignition points on the ground is primarily a function of helicopter speed, gear ratio of the dispenser, and the number of chutes used (up to four). |
