Nursery Seedling Stock Descriptions

Trees and shrubs are graded and sold by size class. Grading is done by species, with stem and root quality considered for each. Minimum sizes are determined by reforestation staff based on seedling survivability after planting. Because of this, some species' sizes can be highly variable.
