A two- year joint research effort on hybrid larch trees by the Hokkaido Forestry Research Institute and the Hokkaido Forest Products Research Institute have discovered that “trees grown from certain pollen and seed trees had 30 percent greater carbon storage capacity, compared to typical larch trees”. A “first hybrid generation between Dahurian Larch as seed trees and larch trees as pollen providers”, called the “F1”, has many desirable features like high seedling survival rates, weather resistance and increased resistance to mice pests, and a higher wood density compared to larch. The F1 hybrid of the Dahurian Larch is said to be the best choice to “enhance cost performance and carbon storage”. The larch tree is a fast growing tree species which is used in industrial plantations and in reforestation projects. The biopact website (URL above) reports that such fast-growing, “carbon capture” tree species would be useful in carbon-negative biofuel production..
