A vital component in silviculture, brushing is essential for ensuring the growth of a stand as young trees fight with other plants and brush for critical resources such as water, sunlight and nutrients. It is also important as a way of reducing or eliminating competition for young trees, as they grow at a far slower rate than many other bush and vegetation.
Forest leaders managing vast areas are challenged with determining the extent of viable crop trees within stands because of the amount of additional vegetation. Until now, heavy investment in aerial surveys, backed up with ‘boots in the ground’ assessments, have been the only method of figuring this out. Multiply that investment across multiple stands – and remote sensing technologies start to make sense.
