RESOURCES project

INTRODUCTION:

As one of the world's top ten forested countries, Australia relies on growers to manage productive, healthy forests sustainably for generations to come. HQPlantations is part of Australia’s plantation timber industry, which includes the forest, wood, and paper products sector - Australia's sixth-largest manufacturing industry.

Aerometrex has been a trusted provider of geospatial data to the company and continues to work with them on a range of use cases. Highlighted below is a case study that showcases some of HQPlantations’ key challenges and demands from a spatial data perspective, which Aerometrex has worked collaboratively to provide solutions for.

THE RESULTS & BENEFITS:

The datasets provided by Aerometrex enabled HQPlantations to extract the core metrics they require to understand the growth and commercial value of their managed forests at scale.

Various teams within HQPlantations have embraced the LiDAR data across a range of use cases. The derived forest structural information has enabled:

• Generation of up-to-date approximations of the timber yield, considering the response to internal and external factors such as the introduction of new genetics or recent climate variations and inter-annual rainfall variations.
• Individual tree detection for achieving a stocking count and potential mortality in younger age stands that haven’t yet hit canopy closure.
• Updating of the detailed terrain information, allowing operational teams to identify the orientation of plantations, natural drainage lines, old site cultivation, ripping & mound contours, and thus aid planning activities such as harvesting events.
• Supplementing satellite imagery with high-resolution aerial imagery to pick up areas that may have been affected by weather events, e.g., scorched in a fire.
• Greater reliance on airborne LiDAR data to supplement ground surveys, for volumetric calculations due to safety and scalability reasons.

Repeat captures shall also allow HQPlantations to have an ongoing and updated view of the younger stands between the ages of 3 to 10 years, to calculate metrics for growth models over time and predict more accurately how the estate shall grow and what it’s worth to their investors.

“We have engaged Aerometrex to conduct a series of airborne LiDAR and imagery campaigns in recent years. This data has now become instrumental in the monitoring of changes to growing stock across our plantation estate. The data has also become increasingly important for the planning of forest operations as the business transitions to precision forestry.”

CONCLUSION:

Projects such as these, provide growers like HQPlantations with clear commercial benefits, related to the increased efficiency in their monitoring operations which reduce the reliance on costly traditional boots-on-ground field surveys as well as increase the scalability of remote sensing solutions. Companies can utilise remote sensing applications to reduce costs and improve the accuracy, precision, and timeliness of plantation characterisation. This can help them as well as their contract partners focus on continuous improvement and innovation towards sustainable plantation management.
