Oddvar SkreAbstract
Seedlings of white birch seem to tolerate high winter temperatures to a higher degree than spruce seedlings, and were also more able to take advantage of elevated CO2 levels. Large differences were observed between provenances in response patterns. The southern provenance of birch was more tolerant against raised winter temperatures than the northern ecotype, and the southern spruce provenance seemed to differ from the two northern provenances in the same way. The Icelandic birch population seemed to have developed a low-growth strategy with strong CO2 acclimation and no significant CO2 responses in photosynthetic rates and growth parameters. This differing response may be explained by long-term selection pressure due to heavy grazing. One of the spruce provenences showed a similar pattern.

Albert WinsentsAbstract
Describes results of a comparison of logging with running skylines on low bearing capacity terrain and typical skyline terrain in Norway. Study addresses technical issues of the same growing concern to minimize logging impact on sensitive terrain. Study also describes use of running skylines over special intermediate supports. Future research needs for mobile tailholds and supports, plus mechanized harvesting opportunities are suggested.
