• |
Common in the forests of the Great Lake states. |
|
• |
Natural Fires in this ecosystem usually occur approximately every 125 to 180 years. |
|
• |
Jack pine is well adapted to fire. |
|
• |
Jack pine seeds have been known to still be viable after exposure to heat at 1000 degrees Fahrenheit. |
|
• |
That heat, however, opens the scales of the cone and releases the seed onto the ground where the fire has removed much of the existing vegetation and litter. |
|
• |
Jack pine seeds require contact with mineral soil to germinate, so fire serves to prepare the seedbed, reduce competition from other plants, and release the jack pine seed. |
