註釋In British Columbia, forest companies are required to reforest logged sites with native species to establish a new crop of trees. They are then required to tend those trees for a number of years to ensure that they survive and grow into a healthy new forest. Once the trees reach that stage, called free growing, the forest company is relieved of responsibility and the trees revert to the responsibility of the Crown. This report investigates the achievement of free growing for new forests across British Columbia through a combination of field review and analysis of the Ministry of Forests silviculture database. The time frame of the investigation covers cutblocks approved after October 1987 & harvested before December 1992. The objectives of the investigation were: to determine accuracy of record-keeping; to verify on the ground, for 291 cutblocks in six forest districts, whether the cutblocks met free-growing criteria and whether they remained free-growing after declaration; to assert compliance with the free-growing requirements of the Forest Practices Code; and to survey, based on the database, for all forest districts the success in achieving free growing within the prescribed time period, the number of cutblocks that required amendments to the silviculture prescription in order to achieve free growing, and the number of cutblocks that did not meet the free-growing requirements & why they did not. Results are presented for the province as a whole and for each selected forest district.
