The Sylvan Stand Structure Model applies stand dynamics principles to data that the you collect from a stand you would like to predict. The model requires more from you but in return provides flexibility. The base model is spatially explicit growth model that is driven by crown size and change. While the modeling effort in 1987, it is actively being develop. This website has a couple of purposes:
Development NewsCurrently Sylvan is undergoing several big changes. Many of the changes are dependent of new additions to our development staff. The biggest change is a rework of the data structure. We will update this website once changes are settled. November, 2009 -- Sylvan modules and functions are listed on a new Status web page. This is to help potential users know about the development status of the program and in the future the status of upgrades. March, 2009 -- Sylvan database structure definitions added ( see Database). This is the start of an extensive set of documentation files to allow users to understand and use the Sylvan data structure. February, 2009 -- Sylvan function library added ( see Functions). The philosophy of this model is to use best available data. The data can come from any sources, your own data collection, published data, or hypothetical relationships. In an effort to make the use of published data easier, we have collected relevant equations into Extensible Markup Language (XML) files. These files provide user machine readable files with citations and Uniform Resource Locator (URL) links. They also include MathML coding of the functions and the parameters for each species published. We hope you find these files a useful reference. |
