LiDAR now used for forestry management

or forest companies, like TimberWest, the health of the trees and associated ecosystems are paramount. From seedling to maturity, the trees must be monitored, and any problems addressed.
The way in which this monitoring happens is changing dramatically through the convergence of new sensing technologies such as LiDAR, and the ability to deploy sensing technology using drones. See more here.
What was once used only for air space and meteorological research, LiDAR, which stands for Light Detection And Ranging and is commonly referred to as airborne laser scanning, is now being used for forest research to more accurately examine everything from the height and diameter of trees to ground terrain evaluation and plot-level wood volume estimates.
In the just-released video , University of British Columbia (UBC) forestry professor Dr. Nicholas Coops emphasizes LiDAR and drone use are just two more recent examples of the forest sectors technological revolution, and the types of technology incorporated into every-day forest management.
“This link between technology and forestry has always been there. I think now it just happens to be exploding at the moment.”
Coops explains LiDAR technology can be used with airplanes or drones and involves sending pulses of light down to the ground that bounce back and mirrors the data captured into images that allow forest planners to measure the topography, depth, height, slope and other values of the land being surveyed.

Domenico Iannidinardo, TimberWest’s Vice-President of Sustainability and Chief Forester says he sees great value in LiDAR technology and drones when it comes to forest management and planning. LiDAR can provide a wide range of enhanced ecological applications such as evaluating microhabitat diversity and watershed modelling. Through the use of LiDAR, forest planners can rapidly and accurately produce three-dimensional data-sets which allows them to better assess road building opportunities, stand value and wood quality, resulting in more efficient inventory management.
“As leaders in forest stewardship internationally and leaders in technological development provincially, the forest industry in Canada has long since understood the need to constantly strive for producing the most accurate and sustainable forest management plans possible,” says Iannidinardo. “That comes from taking full advantage of cutting-edge technologies such as LiDAR and drones.”
Molly Hudson, TimberWest’s Manager of Stewardship and Engagement, echoes Iannidinardo’s comments and adds, “Drones provide us with a high-resolution aerial view that complements our ground-based assessments. We are using them more and more for our reforestation and we are starting to use them in our wildlife management as well, which includes the monitoring and assessment of fish and riparian areas.
UBC’s Faculty of Forestry Dean Dr. John Innes says he is convinced the industry’s integration and adoption of technology will only continue to build momentum in the future.
“Technology is helping forest managers by allowing them access to huge amounts of data more quickly and more efficiently than ever before,” he says. “I believe that the forest industry will continue to use increasing amounts of technology because it will continue to make forestry more efficient, and it’s going to make our practices that much better.”
