i) static equations to fill-in missing data for conifer and hardwood species,
ii) prototype Douglas-fir young-stand site index and tree-level survival functions,
iii) tree growth equations similar in form to those in existing rotation-age individual-tree growth and yield models (e.g., ORGANON, FVS/PROGNOSIS, SPS),
vi) herb and shrub cover, and shrub height projection equations, and
v) routines to perform conifer release from associated vegetation and precommercial thinning.
i) view the tree-list, diameter class stand tables, aggregated stand-level tree attributes (site index, basal area, stem volume, mean height, quadratic mean diameter, and stocking), herb and shrub percent cover and shrub height, and bar-graphs of select stand-level tree attributes (diameter by .. stocking, height, crown width, height-to-crown base, live crown ratio, and stem volume);
ii) direct output (tree list, diameter stand tables, and aggregated stand-level attributes) to a printer or file (a tabular file suited to inspection, or a space-delimited file suited to RVMM, ORGANON, FVS/PROGNOSIS, or SPS input variables); and perform associated vegetation control and/or precommercial thinning.
Coastal and Cascades RVMM -- Individual-Tree accepts input variables in either English or metric units. Input-variables, either read from a file or entered directly include:
i) plantation age and years-to-breast-height, required
ii) topographic information, required (slope, aspect, elevation);
iii) sampling specifications, required if data is entered directly (plot size and number of plots);
iv) expansion factor for each tree, required if data read from a file;
v) shrub and herb percent cover and shrub height, required;
vi) a tree list of conifer and hardwood species including the variables;
- basal diameter at 15 cm (d15), only optional, if height is given;
- breast-height diameter at 137 cm (dbh), required, if height > 137 cm (4.5 feet);
- total height, only optional if d15 or dbh is given;
- crown width, optional and only for Douglas-fir; and
- height-to-crown base, optional and only for Douglas-fir.
