EcoCondition Toolset - A QGIS plugin for ecosystem condition assessments

Area of Science:

• Environmental Science
• Geographic Information Systems (GIS)
• Ecology

Background:

• Ecosystem condition assessment is crucial for environmental management, requiring integration of diverse geospatial data.
• Existing methods for spatially explicit ecosystem condition assessment can be complex and data-intensive.
• There is a need for user-friendly tools to support environmental objectives like nature restoration and sustainable use.

Purpose of the Study:

• To present the EcoCondition Toolset, a QGIS plugin designed for user-friendly ecosystem condition assessments.
• To simplify the integration and analysis of diverse geospatial data for evaluating ecosystem quality.
• To provide a flexible methodology for calculating ecosystem condition indices that support policy and decision-making.

Main Methods:

• Development of a QGIS plugin implementing a GIS weighted-sum methodology.
• Sequential toolsets for data preparation: layer alignment, no-data handling, multicollinearity testing, indicator normalization/inversion.
• Calculation of six ecosystem attribute composites (Physical, Chemical, Compositional, Structural, Functional, Landscape) based on user-selected raster variables.

Main Results:

• The EcoCondition Toolset automates multicollinearity screening, normalization, and flexible weighting for ecosystem condition assessment.
• The plugin calculates six key ecosystem attribute composites, allowing for adjustable weighting of variables and composites.
• The resulting ecosystem condition index accurately reflects severity and variation among ecosystem states.

Conclusions:

• The EcoCondition Toolset provides a robust and accessible method for spatially explicit ecosystem condition assessment.
• The tool supports informed land-use decision-making, conservation, and restoration efforts.
• This GIS-based approach enhances the practical application of ecological assessment for environmental management.
