Forest Insights to revolutionise forest inventory management

For immediate release
15 November 2023

Scion, in collaboration with Indufor Asia Pacific Ltd, has revealed a prototype for a new interactive tool providing the forestry industry with powerful inventory information to make management, harvesting and wood processing decisions easier.

Called ‘Forest Insights’, scientists from the Crown Research Institute outlined the tool’s capabilities and applications for the industry at ForestTECH 2023 in Rotorua this week, Australasia’s premier forestry technology event for forest managers, remote sensing specialists and tree crop managers.

In a world increasingly driven by data and technology, the interactive Forest Insights tool powered by machine learning and deep learning models provides forest owners, managers and wood processors with an overview of the changing availability and growth of planted radiata pine over time.

The prototype is currently focused on modelling of East Coast pine forests but Scion has plans to provide the same data and for a wider range of trees for other regions, with Bay of Plenty next cab off the rank.

Scion portfolio leader for New Value from Digital Forests and Wood Sector, Grant Evans, says the prototype will support forestry and wood processing companies to make more informed management decisions.

“Long term, it will help anyone with trees planted know their precise location and ultimately, what they can do with the trees in the future.”

Forest Insights is more than just a mapping tool; it’s set to become a window into the heart of commercial forests. It has been built using cutting-edge AI technologies as well as LiDAR, to detect and identify stands of trees to quantify their volume and maturity over time. It outlines the boundaries for each stand of trees and provides essential details, such as age class, area in production, and the number of stems per hectare.

Forest Insights also tracks the history of planting and harvesting, which provides valuable insights into changing inventory levels.

This inventory data is more than statistics; it’s the key to unlocking investments and strategic decisions for stakeholders across the timber supply chain.

Automatically detecting commercial radiata pine forests using trained Deep Learning Convolutional Neural Networks by their boundaries is a game changer for forestry companies. What used to be a laborious task of drawing polygons is now replaced with the click of a button.

Additionally, Forest Insights levels the playing field for smaller forest owners, Evans says. “These individuals, who own smaller woodlots or stands, can use the tool to see where other small lots in their region are maturing at a similar time and potentially co-operate to negotiate better pricing from mills.” This democratisation of information ensures that the benefits of Forest Insights extend to all players in the industry.

As a prototype it offers a glimpse into the future, with researchers already planning features that will provide additional value.

Scion is already working with the University of Canterbury to identify tree species beyond radiata pine, aligning with the Government’s goal of having 20% non-radiata pine forests by 2030. Currently, such measurements rely on people voluntarily reporting their data, making it difficult to track progress. Forest Insights intends to change that by using satellite imagery and LiDAR data from Toitū Te Whenua Land Information New Zealand to detect different tree species accurately and utilise Indufor’s dashboarding expertise.

Users can use Forest Insights to view by patch information about age class and query estimates of productivity, harvest information and transport distances.

Harvest tracking

Beyond tree species identification, the prototype goes a step further by automatically tracking forest activities. Collaborating with Indufor Asia Pacific Ltd who enhanced the detection training, each orange segment on the map represents an area where harvesting has occurred. This functionality not only helps in tracking inventory but it is hoped, with further training, it will provide a means to assess forest damage following natural disasters.

“For the East Coast, it could also be used as a tool to reveal where planted forests are being abandoned or are no longer being harvested due to concerns relating to planting on erosion-prone land,” says Evans. “For forestry and wood processing companies, this data offers them a holistic view of their assets and a basis for well-informed decisions.”

The granularity of the information available from Forest Insights offers huge benefits to industry and investors alike, says Dr Pete Watt from Indufor’s Resource Monitoring Team. “Such information provides the cornerstone for developing wood availability forecasts that underpin investment decisions and support infrastructure planning and policy settings.”

The journey of Forest Insights started in 2022 and is a collaborative effort. Scion’s data scientists have supplied all the models and data, working with Indufor Asia Pacific Ltd to create the online tool and dashboard interactivity.

Testing with a handful of industry users has yielded positive feedback, with at least one forestry company expressing interest in using Forest Insights to validate their commercial forestry decisions.

Other collaborators have expressed interest in joining the Forest Insights project, and with their support Scion aims to expand its reach across New Zealand.

The aim is to expand its functionality and develop layers of complexity over time. Scion researchers have a grand vision for the prototype to serve as the foundation for a digital twin of New Zealand’s entire forestry estate.

“Imagine having access to information on Eucalyptus trees’ age, harvest readiness, and potential markets, including its suitability for pulp and paper, or feedstock for biorefineries, all neatly presented on a map,” says Evans.

“By continuing to work collaboratively with industry and our key partners, we’re committed to expanding the capabilities of Forest Insights to meet everyone’s needs and add value to the forestry and wood processing sectors.”

Claire Stewart, programme manager for the FGR-led Precision Silviculture Programme, says inventory management tools are critical to being able to see our national forest scape more holistically and to support foresters manage at a finer grain level of detail.

“There are simple tasks that machine learning models can assist us with like boundary mapping, cut over mapping and post-plant survival assessment,” she says. “By having a platform that pools data to create robust models we can move a lot quicker.

“On a national level, a tool such as this provides insights on a bigger scale that can inform our wood flows, logistics and national carbon accounting. It’s an exciting space and it’s great to see leadership from Scion and Indufor with this initiative.”


The prototype can also reveal areas where harvest activity has occurred.
