Fire
- A Fundamental Force
Like
wind, rain, and sunshine, fire is a part of the Yellowstone
ecosystem.
Plants
decompose very slowly in Yellowstone's cool, dry environment.
Fire speeds up this process.
Wood
and other organic material are turned into ash. Minerals and
valuable nutrients then fertilize the soil.
Natural
fires burn in a patchy pattern - a mosaic. New openings in the
forest allow sunlight to reach the ground.
Grasses,
flowers, shrubs, and seedling trees grow quickly in these sunny
fertile areas.
This
exhibit made possible by a generous grant from the Yellowstone Association.
Graphics
on the sign
In
addition to the text there are pictures of lodgepole pines showing the recovery
of the forest after fires, and pine cones.
