Timing and setting up logging infrastructure
This web article explains
how landowners, loggers, and foresters can use maps and weather
information to document plans for the physical portions of a timber
On a baseline map of the timber harvest site, mark the critical
areas identified while reviewing the planning information:
- Ravines and
- Dry washes
- Wetlands and
- Steep slopes
the main landing and entry point. The landing should be outside
a streamside zone, and more than 200 feet from water bodies if
possible. Plan on using a filter strip of vegetation between landings
and neaby water bodies.
Determine if existing
roads will be useful. If an existing road is poorly constructed,
and many are, it is often better to put it to rest by seeding
it, installing waterbars, and blocking it off. Plan routes of
new roads and trails to avoid creating erosion problems. Many
older forest roads were designed for winter use only.
Mark potential forest
roadways, using the contour as a guide. To the extent possible,
follow the contour of the land. On hillsides, use switchbacks.
Wherever the road is placed, make sure it will be graded for good
Avoid steep areas,
such as gullies, ravines, outcroppings, and cliffs. Major
erosion hazard. If you are going to extract timber from these
areas, plan to use winching equipment, erosion matting and other
erosion control materials and techniques.
Avoid wet areas,
springs, and intermittent streams. If plans call for crossing,
use one of the options such as corrugated trail, pole fords, etc.
the timber harvest for the appropriate season. A timber harvest
during winter conditions minimizes erosion as long as the soil
is frozen solid. Summer condition timber harvests are good on
soil that is seasonally wet, yet is dry enough to support equipment
through the summer. In areas where the soil never seems to freeze
or dry out, reconsider the timber harvest. The damage to the forest
may be more than the timber is worth.
