1 Newfoundland Fibre Inventory Project Maximizing the value of forests through enhanced inventory of fibre attributes

2 Background CBPPL Atlantic Innovation Fund (AIF) Project maintain and increase the competitiveness of CBPPL and the province s forest industry by making better use of wood and fibre resources. Enhanced Fibre Inventory Project maximize the value of Newfoundland s fibre resources through the development of an enhanced inventory of fibre attributes in the forest.

3 CBPPL AIF Project Objectives 1. Determine wood fibre properties in standing trees and on chip streams feeding CBPP 2. Establish databases of wood and fibre properties that can be incorporated into the provinces digital forest inventory (GIS) framework 3. Develop models relating key wood fibre properties to the mill s processing parameters and end-product properties.

4 CBPPL AIF Project Activities Project has several distinct activities on-going which can be grouped into two major categories: 1. Forest related 2. Mill related

5 Forest Related Activities 1. Core Sample Collection 1930 cores 2. Core Sample Analysis 3. Field Probe Testing 4. Correlation of Data to Forest Conditions 5. Integration into Provincial Forest Inventory

6 Mill Related Activities 1. On-line NIR Chip Sensor 2. Process / Product Modeling 3. Mill Trials 4. Fibre and Process Optimization Strategies

7 Conclusion By the end of the project we should have: forest inventory GIS maps showing the fibre characteristics important to mill processing and paper quality. Also important for lumber industry. a mill yard that has wood sorted based on fibre properties, not simply species improved mill efficiency based on our ability to manage the fibre characteristics of the wood feeding the mill the ability to better match end-product quality to customer demand by better controlling the inputs and the processing.

8 Enhanced Fibre Inventory System Spatially-explicit information on the attributes contained in Newfoundland s fibre basket Attributes need to be related to product potential and value GIS layers that can support: better harvest planning segregation of raw materials according to end-use and for maximum value

12 Data management Geodatabase A central data repository for spatial data storage and management

13 Inventory Tools for measuring and mapping forest structural attributes related to value e.g. species, height, diameter, basal area, branchiness, gapiness, leaf area index, etc.

14 Correlations Models Maps for predicting and mapping intrinsic fibre attributes from measured structural and environmental variables e.g. fibre length, width, wood density, microfibril angle, etc.

15 Fibre attributes Wood density Modulus of elasticity Fibre wall thickness Microfibril angle Fibre length Coarseness Ratio of radial to tangential fibre diameter *Attribute Database (from CBPPL AIF Project) 7 attributes 193 plots 10 trees per plot ~1930 cores individual ring measurements

18 1. Terrestrial LiDAR (J.F. Coté) Architectural modeling for detailed characterization of tree and plot structure (e.g. crown dimensions, branchiness, gapiness, leaf area, etc.)

19 2. High Resolution Imagery & Airborne LiDAR Methods and models for withinstand estimation and mapping of forest structure attributes Species classification Stand delineation Structural attributes by species within a stand E.g. - # of stems - average crown area - average height - height standard deviation - leaf area index -biomass -.

22 5. Plot/Stand Level Models (E. Lessard) Modeling and mapping fibre attributes using existing forest inventory and environmental layers (site, stand and tree characteristics) Predicted fibre attribute

23 6. Enhanced Plot/Stand Level Models (D. Blanchette) Modeling and mapping fibre attributes using forest structure attributes derived from airborne LiDAR and/or optical imagery

24 Enhanced Fibre Inventory System Supporting value chain optimization by adding detailed forest structure and related fibre attributes to the forest management inventory Inventory Planning / Processing Products

25 Benefits Use information about fibre attributes to allocate wood for best end use Feed harvest planning systems with more precise data Control variability in fibre attributes going into the mill Better meet customer demands for products with specific quality characteristics (e.g. strength) Create opportunities to expand or develop new products

26 Competition / Alternative Existing system Volume based attributes represent amount of wood e.g. species, height, crown density, age, merchantable volume Based on photo interpretation Represent average stand conditions Enhanced system Value based attributes linked to product quality e.g. wood density, fibre length, microfibril angle, etc. Based on semiautomated processing Represents withinstand variability and distributions
