What's New
Version 6.06 released March 31, 2006
Note: If you have a parameter file from an earlier version, and you are using behaviors that have been updated in version 6.05, load your file and save it. SORTIE-ND will automatically make any needed adjustments to your parameter file.
New in version 6.06:
- New allometry equation for saplings - the power diameter-height relationship
- Updated allometry equation - the DBH - diameter at 10 cm relationship now has an intercept term
- New seed survival behavior - Storm Light Dependent Seed Survival, which works with the light levels produced by the Storm Light behavior
- New mortality behavior - Stochastic Bi-Level Mortality, which uses two different mortality rates in high and low light
- New disturbance behavior - Windstorm, which follows a given storm regime to produce storms and kill trees as a result
- New growth behavior - Basal Area NCI Growth, which calculates tree growth as a function of neighborhood basal area
- New light behavior - Basal Area Light, which calculates light levels as a function of neighborhood basal area of angiosperms and conifers
- New disturbance behavior - Storm Killer - that kills trees damaged in storms. This behavior takes over and expands a function previously performed by the Storm Damage Applier behavior
- New analysis behavior - Tree Age, which tracks tree ages
- New mortality behavior - Height-GLI Weibull Mortality, which calculates tree mortality as a function of tree height and light levels
- New growth behavior - Puerto Rico Storm Bi-Level Growth, which uses two functions to calculate growth before and after storms
- New analysis behavior - Merchantable Timber Value, which calculates the value of merchantable timber in a plot
- New analysis behavior - Carbon Value, which calculates the amount of carbon in a plot and its value
- Stand and Stock output tables now display species-specific values as well as plot total values
- The Storm Light behavior has an updated equation for light calculation
- The main window is now equipped with scroll bars, to allow you to use more space when viewing charts and graphs
- The Tree Setup window is now capable of changing the name of a species
- The Density Dependent Seed Survival behavior has been updated to ensure the survival of at least one seed per cell, and its survival area has been standardized to per square meter
- The Relative Michaelis-Menton growth behaviors now have an additional exponent on diameter
- The Substrate behavior uses a new equation for decayed log decay
- Developers: The C++ model code has been ported to the GCC compiler set and the Eclipse development environment
Version 6.05 released August 3, 2005
Note: If you have a parameter file from an earlier version, and you are using behaviors that have been updated in version 6.04, load your file and save it. SORTIE-ND will automatically make any needed adjustments to your parameter file.
New in version 6.05:
Version 6.04 released May 16, 2005
Note: If you have a parameter file from an earlier version, and you are using behaviors that have been updated in version 6.04, load your file and save it. SORTIE-ND will automatically make any needed adjustments to your parameter file.
New in version 6.04:
- You can now choose the appropriate allometry equation for each species for each life history stage
- You can now set the height boundary between seedlings and saplings for trees
- The establishment behaviors have been restructured, allowing you to mix and match seed survival effects
- The Storm damage applier behavior can create tip-ups from storm-killed trees
- New harvest behavior - Selection harvest - that allows SORTIE-ND to decide when to perform harvests based on target basal area levels
- New behavior - GLI Points File Creator - which calculates GLI at certain specific points
- New light behavior - Storm Light behavior - that uses storm damage as a proxy for finding light levels
- New growth behavior - Puerto Rico semi-stochastic growth
- New growth behavior - Linear bi-level growth - that can grow trees with two sets of parameters based on light level
- New growth behavior - Lognormal bi-level growth - that can grow trees with two sets of parameters based on light level
- New mortality behavior - Logistic Bi-Level Mortality - that can use two sets of parameters based on light level
- NCI growth and NCI Mortality now each have a flag for whether or not to include snags in NCI calculations
- Refinement of substrate dynamics for snags, allowing them to tip-up at different rates from live trees
