Species Distribution Models Enhance Timber Supply Chain Verification

Species Distribution Models (SDMs) can significantly improve the accuracy of timber supply chain verification by assessing the climatic suitability of declared harvest countries.

01

Key Findings

  • 01SDMs can identify climatically suitable but undocumented range countries for timber species.
  • 02Most unconfirmed harvest country declarations were linked to misidentification of species rather than declaration of manufacturing countries for value-added products.
  • 03SDMs provide a tool to assess the plausibility of declared timber harvest locations.
02

Application

Design takeaway

Integrate ecological suitability modelling into the timber sourcing process to validate declared harvest origins and identify potential risks or new sustainable sources.

How to apply

When sourcing timber, use available species distribution data or develop models for key species to assess the climatic suitability of the declared harvest country. Cross-reference this with import declarations and known species ranges.

Project actions

  • 01When selecting materials, consider the geographical origin and ecological suitability of the species.
  • 02Explore using publicly available species distribution data to inform material choices and risk assessment.

Method & Evidence

AimCan Species Distribution Models (SDMs) be used to identify anomalies in timber supply chains by comparing predicted species ranges with declared harvest countries?
MethodModelling and Comparative Analysis
ProcedureSpecies Distribution Models (SDMs) were developed for American mahogany species (genus Swietenia) using presence-absence and presence-only occurrence data. The predicted species ranges were then compared against US import declarations for Swietenia species. Each declared species-country pair was classified as confirmed or unconfirmed based on known ranges and then as suitable or unsuitable based on the SDM output. Unconfirmed but climatically suitable pairs were examined for potential new range countries or misdeclarations.
ContextTimber supply chains, particularly for high-value or endangered species, international trade, ecological modelling.

Variables

IVDeclared harvest country and species; climatic suitability data.
DVConfirmation status of species-country pair (confirmed/unconfirmed); suitability status based on SDM (suitable/unsuitable).
CVSpecies (Swietenia genus); US import declaration data; geographical and climatic data used for SDM development.

Strengths & Limitations

Strengths

  • +Provides a novel, data-driven approach to supply chain verification.
  • +Addresses a critical issue in sustainable resource management and international trade.

Limitations

The availability and accuracy of species distribution data can vary significantly between different timber species and regions. The models do not account for all factors influencing timber trade, such as economic drivers or political stability.

Reliability & validity

The reliability of the findings depends on the accuracy of the SDMs, which are influenced by the quality of input data. Validity is supported by the comparison with import declarations, but the study acknowledges potential for misdeclarations that are not solely based on geographical suitability.

Think critically

To what extent can Species Distribution Models fully account for the complexities of global timber trade, including illegal logging, political factors, and the trade of processed goods?

05

Design Principles

"Ecological plausibility is a critical component of supply chain integrity."

This research offers a novel method for designers and supply chain managers to identify potential anomalies and risks in timber sourcing. By leveraging ecological data, it provides a more robust approach to ensuring the legitimacy and sustainability of wood products, moving beyond simple declaration checks.

What This Means for Your Design

Imagine you're buying wood for a project. This study shows how scientists can use computer models to check if the wood really comes from the country claimed, by looking at the climate there and if the tree actually grows there. This helps catch fake claims and find new places to get wood.

How to use in your project

  • 1.Use the concept of Species Distribution Models to justify the selection of specific timber sources, explaining how you verified their origin and ecological suitability.
  • 2.Reference this study to support claims about the robustness of your material sourcing strategy.

Paragraph starter

This design project prioritizes ethical and sustainable material sourcing. To verify the origin of timber, a method analogous to that proposed by Pollack et al. (2026) was considered, which utilizes Species Distribution Models (SDMs) to assess the climatic suitability of declared harvest countries. By cross-referencing import declarations with ecological data, potential anomalies in the supply chain can be identified, ensuring greater confidence in the provenance of materials.
