Other claims from this paper (8)
- Association Mountain pine beetle attack was associated with substantially lower moisture content, starch and sugar proportions, and crude fat in lodgepole pine foliage.
- Association Foliage of beetle-attacked trees had higher proportions of lignin, cellulose and hemicellulose.
- Association Emission rates of several terpenes increased in yellow foliage.
- Intervention effect Fresh yellow and red foliage of beetle-attacked trees had increased ignitability and sustainability compared with unattacked green foliage.
- Intervention effect Fresh yellow and red foliage of beetle-attacked trees had lower temperatures at ignition than unattacked green foliage.
- Intervention effect Fresh yellow and red foliage of beetle-attacked trees had higher heat yields than unattacked green foliage.
- Association Fuel moisture is overwhelmingly important for flammability.
- Association Fuel chemical composition has significant effects on lodgepole pine foliage flammability.
