Highlights of Douglas fir natural regeneration.

Abstract

Enough natural reproduction to produce a fully stocked stand immediately after logging occurs on only a small percentage of the clear-cut and broadcast-burned areas in the Douglas fir region. Studies have been made of the environmental factors that enter into this rather hesitant transition from old forest to new in order to work out a silvicultural system for the type that will result in more prompt and adequate restocking following logging, and some of the more recent findings are given in the following paragraphs.
