It seems like we are growing many roads with a tree here and there and
calling that a forest. What is the solution? Close most of the roads! One
of the biggest parks in Europe is doing just that! So it can be done. It is
a sound treatment for health of a forest or park. Roads change the pathways
of water, allow grass to compete with trees, and disrupt the mycorrhizae and
other tree associates. And when trees get sick, all the associates of trees
also get sick. Ask a koala!

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
