Site index tools (SiteTools)

About SiteTools

SiteTools is a user-friendly site index calculator for Windows. It provides access to many site index related functions for 24 tree species in B.C.

SiteTools equations

Some of the equations SiteTools handles include:

• Site Index (height-age) equations
• Years-to-breast-height equations
• Growth intercept equations
• Site index conversion equations

SiteTools functions

Other functions of SiteTools include:

• Enabling age input/output as total tree age or breast height age
• Providing an alternative to site index equations for ages below 50 years 
  • ​Note: This function is only available for some species
• Predicting the site index of one species from the site index of another
  • ​Note: This function is available for only some species pairs
• Providing multiple equations for some species 
  • ​Note: Ministry recommended equations are identified, which represent the equations used in most ministry growth and yield applications, including Table Interpolation Program for Stand Yields (TIPSY) and Variable Density Yield Projection (VDYP)

SiteTools produces custom site index tables and graphs, and also functions as a handy site index calculator. It also includes a separate batch routine for processing large data files.
