Pre and Post Harvest Considerations
Look at the following pictures and think about things that must be considered Pre
Harvesting of Trees and Post Harvesting of Trees.
Areas that are ecologically sensitive and could not recover from harvesting (unsustainable) should not be logged.
3Type of soil (will the soil have enough
nutrients to support re-growth?) not possible in rain forests
4Climate (is there appropriate amounts of rain
and temperatures ranges for the forest to re-grow) (is there a change in the amount of light)
6Surroundings (Location) (will it affect nearby
ecosystems such as streams and ponds? Does it fragment a larger ecosystem?
1, 2Mechanical Preparation – clear away the
logging debris (duff and slash) with equipment
Slash burning – Removes debris by burning. This is low in cost and good for steep slopes.
3, 4Herbicides – Controls weeds with chemicals
so trees don’t compete for resource. May harm wildlife and remove cover.
Planting – Replant with genetically improved seedlings. (most Pa forests will re-seed themselves)
