How To

ℹ️

This tool is currently in development. We plan to use the josh simulation engine to perform vegetation modeling analyses. Integration approaches are under development in the josh-toolbox-demo repository.

Getting Started with josh

Planned Toolbox Integration

When using josh within the Disturbance Toolbox workflow will involve:

Step 1

Obtain a disturbance severity map from Disturbance Severity

Step 2

Using the Vegetation Modeling tool, import the disturbance severity map into a parameterized josh model for the target ecosystem, as initial conditions indicating where the disturbance occurred and how severe it was

Step 3

Configure scenarios with relevant external data (likely external climate data such as projections of temperature, precipitation, for example, or geographic sources such as a digital elevation map for elevation)

Step 4

Run simulation ensembles with multiple replicates to properly characterize uncertainty

Step 5

Export outputs for vegetation impact analysis, or comparison with management intervention outcomes in Resource Optimization

Current Limitations

Models must be parameterized before use - new vegetation communities or intervention types require model development
Landscape-scale simulations require cloud computing resources
Model validation is ongoing for Mojave Desert communities
