Spec2Harv was developed to automate the conversion of harvest schedules generated by the Spectrum model into script files that can be used by the HARVEST simulation model to simulate the implementation of the Spectrum schedules in a spatially explicit way.
Spectrum produces output files that include the acres to be treated with various timber harvest methods by Analysis Unit over the time period of the planning horizon. If the Analysis Units are designed to coincide with Management Areas (MA) and forest types (FT), the output can be converted into the parameters that HARVEST requires for spatial simulation. This conversion is not trivial because Spectrum produces treatment prescriptions for each Analysis Unit over all time periods in a single record, while HARVEST sequentially implements all treatments for all Analysis Units (MA and FT combinations) within each time period.
Spec2Harv was designed to automate the conversion process. Algorithms were developed to interpret the Spectrum output and to automatically create a HARVEST script file. Script files eliminate the need to manually specify the harvest parameters for each Analysis Unit, saving time and reducing the risk of typographical errors. Because Spec2Harv is designed to produce input files for the HARVEST model, the user should be familiar with the HARVEST v6.1 User’s Guide (Gustafson and Rasmussen 2002), which can be found at https://www.nrs.fs.fed.us/tools/harvest/
Spec2Harv was written by Luke Rasmussen in Fortran 95 using the Winteracter Windows libraries. Larry Leefers, Eric Gustafson, Phil Freeman and Luke Rasmussen developed the conceptual design.
