This study covers eighteen clearcuttingsites performed by five different logging crews. The clearcuttingsites are located in the five Norrbotten municipalities Älvsbyn, Piteå, Boden, Luleå and Kalix with locations from the coast and several 10 km from the coast and in to the country. The job requestor wanted to know how well the result concerning creation and preserving of the biological diversity in connections with clear cutting correspond to the requirements that FSC sets on certified companies. No FSC- certified real estate was included in the study. After performed inventory and summary of the material the result show that sixtyseven percent of the performed clear cutting sites validated according to FSC: s requirements. The remaining thirty-three percent, which is six clear cutting sites, did not cope with the requirement due to reasons that varies from case to case. On one of the sites it had became large and deep damages on the ground on the basis road to the cutting site and also ground damages on the cutting site from the machines and that it was too few natureconservationtrees left on the cutting site. On other sites the grade could have been increased if there hade been left more high stubbles with associated tops and eternity trees or environment trees on or in connection with the cutting site. When you look at the different factors that influence the grade the consideration requiring the measures as logging by sensitive biotopes, leaving of protection zones, considerations by culture remains, considerations by flora - and fauna premises most of the time got high grades. When you look at ground damages and water care there have been cutting sites with full consideration taken and also such where the considerations have been poor. A mount of saved trees and dead wood as one may think will bee the simplest factors to influence have been those who got the poorest grade. Since there are nine different factors that enters into the evaluation in order to assess if the site has coped with the requirement in order to become FSC-approved or not, one or more factors can be rejected if there are other factors with higher grades. If there is a factor that is non-present before the logging starts none consideration will be taken to that. In this way an cutting site with few tree species still can bee approved if the machines has created natural resources as high stubble with associated tops left on the ground or a group with trees that in the future can become trees of high value for nature conservation. On all of the six rejected sites there where rather few consideration factors to take into consideration but with quite simple means there had been possible to increase the grade on some off the factors to get a higher final grade.
