Introduction
This web site lists the many different techniques forest owners
and forest workers should be using to control erosion during a
timber harvest. Forest owners can apply these practices to smaller-scale
projects like firewood cutting and timber stand improvement as
well.

The
key concept in preventing forest soil erosion during logging
is to contain small amounts of water over short distances.

Moving
water has tremendous energy. Each gallon of water flowing down
a skid trail or through a log landing has the potential to carry
away several pounds of loose soil. An afternoon of rain on a forty-acre
hillside deposits more than two million gallons of water. This
water has the potential to wash away hundreds of tons of forest
soil, which will take more than 100 years to re-develop.
Best
management practices reduce the amount of forest soil washed or
blown away in adverse weather. They have been proven to improve
the quality of streams and ponds by reducing sediment. Through
all these practices, the principle remains: contain small amounts
of water over short distances.
Physical
control of sediment and erosion starts the minute a logging crew
arrives at the timber harvest site. Within the first few hours
or days, they establish the attitudes and procedures that will
keep forests soil erosion to a minimum. Before the first chainsaw
is started, several hours of preparation, map reading, and walk-throughs
have already taken place. If a crew shows up on a job site unprepared
for erosion control, the forest and area streams will suffer irreparable
or expensive damage.
Landowners
and foresters can help prepare a logging crew by making it clear
that erosion control is a priority. It is very important to meet
together and explain how, when and where erosion is to be managed.
Best
management practices are an economical approach to timber harvesting.
Compared to the cost of repairs, BMPs are relatively cheap and
easy to install.
