General System description

System name: Conifer Timber Quality

Brief overview

Part of the GB Forestry Decision Support System, this tool enables the user to get some Sticka spruce timber features as the percentage of juvenile wood, the average denisty, etc.

Scope of the system

This system insists on the influence of stand characteristics as stocking density, yield class or thinning treatments in the quality of the wood obtained from this stands.

System origin

Authors
Currently free to use via web.
Use

Support for specific issues

Timber quality analysis.

Support for specific thematic areas of a problem type

Silvicultural
Development choices / land use zoning
Policy/intervention alternatives
Sustainability impact assessment (SIA)

Capability to support decision making phases

Allows user to vary management options in order to obtain better quality wood

Related systems

Describe (and/or link to) other systems related

Data and data models

Typical spatial extent of application

Web based tool operates at stand scale, as the wood quality characteristics resulting belongs always to trees growing in stockings.

Type of information input from user (via GUI)

Species (at this moment only stika spruce is allowed), yield class, age, stocking density and thinnings schedule.

Models

Forest models

Growing models and wood quality models.

Decision Support

Definition of management interventions

Silvicultural interventions in obtained wood quality.

Typical temporal scale of application

Has some support for future climate scenarios, baseline data is from 1961-1990.

Types of decisions supported

Management level
- strategic decisions
- administrative decisions
- operating control decisions
Management function
planning decisions
- organizing decisions
- command decisions
- control decisions
- coordination decisions

Output

Types of outputs

Current version generates tables via web.

System

Installation

Web browser
