The Canadian forest industry is worth $57 billion dollars, employs over 230,000 Canadians, and contributes over 10% of the Gross Domestic Product. Critical to the industry is the quality of the 650 million seedlings planted every year. Individual tree evaluation in progeny and provenance trials are essential for ranking and selecting the best genotypes and populations to ensure maximum target growth and yield attributes and adaptation, a critical endeavor for sustainable forest management decisions. This project is a unique collaboration across the forest genetics value chain between UBC, the BC Forest Improvement and Research Management Branch and FYBR Solutions, a forest analytics company, with the aim of developing and demonstrating innovative, and ultimately, operational approaches to measure characteristics of Spruce trees grown from natural stand and genetically selected populations, planted across BC and the Yukon. By developing new approaches to more quickly, effectively and accurately measure the height, diameter, and crown dimensions of provenance trials, this project will position Canada as a global forest genetics leader, not only in the genetic improvement of critical, economically valuable forest tree species, but in the field of seed breeding and climate adaption.

加拿大林业价值 570 亿加元，雇用了超过 23 万加拿大人，贡献了国内生产总值的 10% 以上。对于该行业来说至关重要的是每年种植的 6.5 亿株树苗的质量。后代和种源试验中的单株树木评估对于排序和选择最佳基因型和种群至关重要，以确保最大的目标生长和产量属性和适应性，这是可持续森林管理决策的关键努力。该项目是 UBC、不列颠哥伦比亚省森林改良和研究管理分部和森林分析公司 FYBR Solutions 之间跨森林遗传学价值链的独特合作，旨在开发和展示创新的、最终的操作方法来衡量云杉树由自然林和经过基因选择的种群生长而成，种植在不列颠哥伦比亚省和育空地区。通过开发新方法来更快速、有效和准确地测量种源试验的高度、直径和树冠尺寸，该项目将使加拿大成为全球森林遗传学的领导者，不仅在关键的、具有经济价值的森林树种的遗传改良方面，而是在种子育种和气候适应领域。
