MGM Support Tools Download
MGM Support Tools are utilities that facilitate the setup, execution, and analysis of MGM projections. These Support Tools are available in four Excel workbooks: “MGM Make Stands”, the “MGM CMI Solver”, the “MGM Record Extractor”, and the “MGM Batch Macro”. Each MGM Support Tool can be downloaded below with a step-by-step User’s Guide.
MGM Make Stands
The MGM Make Stands workbook prepares tree data for MGM, identifies common data errors, and creates MGM Stand Worksheets. The MGM Make Stands User’s Guide also includes detailed instructions and formatting rules to prepare tree data for MGM.
MGM CMI Solver
The MGM CMI Solver workbook calculates mean Climate Moisture Index (CMI; Hogg et al. 2013) for the 30-year period between 1981-2010 using ClimateNA (Wang et al. 2016) Version 6.11 data. Mean CMI from 1981-2010 is required to run MGM’s climate-sensitive survival functions (Cortini et al. 2017; Comeau 2021a) and maximum size-density relationship (Comeau 2021b). CMI must be calculated using the MGM CMI Solver and ClimateNA Version 6.11 data. Other versions of ClimateNA may not be used to calculate CMI. The download link for ClimateNA Version 6.11 is available below.
*The MGM CMI Solver User’s Guide outlines:
- How to prepare input data for ClimateNA Version 6.11.
- How to install and run ClimateNA Version 6.11.
- How to calculate CMI using the MGM CMI Solver.
**ClimateNA (Wang et al. 2016) Version 6.11 is subject to its own terms of use.
MGM Record Extractor
The MGM Record Extractor workbook converts MGM Records (i.e. long-form MGM outputs) into a tabular format for data analysis. The MGM Record Extractor is designed to help users that execute crop plans using MGM’s Graphical User Interface (GUI). Users of the MGM Batch Macro do not need the MGM Record Extractor.
MGM Batch Macro
The MGM Batch Macro workbook allows MGM to run tens, hundreds, or thousands of projections using plot summary information and MGM Stand Worksheets (e.g. MGM Stands.xlsx). The MGM Batch Macro also records long-form MGM outputs in a tabular format for data analysis. Users of the MGM Batch Macro must be familiar with crop plan development, crop plan execution, and MGM’s options/establishment settings.
Technical Support
