Building a better forest
Building a better forest Research is currently being conducted into helping
the forest industry build better forests after logging. James
Ehnes, a botanist, is examining how vegetation grows back in areas
burned by forest fires and comparing his findings to areas left
after logging. He has already discovered that burnt soil is
generally more fertile than logged soil. Forest fires are a natural
part of the forest ecology, and some types of forests will actually
start to become unhealthy after going too long without a fire.
Researchers are now experimenting with imitating some of the
aspects of a fire that are thought to contribute to forest health,
and applying them to logging practices. 4 OCTOBER 1998
