The Democratic Republic of Germany now has a total area of 195 hectares and a forest coverage rate of 27%. Last year, it produced 10 million cubic meters of wood and 11,000 tons of resin. Democratic Germany started large-scale afforestation since 1945 and started extensive forest tending work from 1955 onwards. Since 1969, the area of afforestation has been renewed every year, down from 60,000 hectares in the 1950s to 20,000 hectares. The tending protection has dropped from 200,000 hectares in the 1950s to 100,000 hectares in the 1970s. At present, the total stock of forest in Democracy Germany ranges from 500 million to 704 million cubic meters, with an average of 170 to 180 cubic meters per hectare. The total annual growth of trees is 19.53 million cubic meters, with an average annual growth rate of 5.4 cubic meters per hectare. Enter eight
