In discussing the data obtained from the one 11 m tall white spruce, Fraser et al. (1964) [25] speculated that if the photosynthate used in making apical growth in 1961 was manufactured the previous year, then the 4 million needles that were produced up to 1960 manufactured food for about 600,000 mm of apical growth or 730 g dry weight, over 12 ...
A leaf area index (LAI) expresses the leaf area per unit ground or trunk surface area of a plant and is commonly used as an indicator of the growth rate of a plant. LAI is a complex variable that relates not only to the size of the canopy, but also to its density, and the angle at which leaves are oriented in relation to one another and to ...

The strategy aims to increasing forest coverage to 21% of the total area of Scotland by 2032, with the target rate of afforestation rising from 10,000 hectares per year in 2018 to 15,000 hectares per year by 2024. Within this, the government is seeking to establish 3000–5000 hectares per year of new native woodland. [34]
