Forest Growth and Yield Modeling CACTOS - CRYPTOS
Forest Growth and Yield Modeling
CACTOS
Predicting how forests change over time is difficult. So many variable come into play, species, site quality, trees density, tree spacing, crown size, and many others. When you add management to the mix, making accurate predictions is difficult.
CACTOS, the California Conifer Timber Output Simulator is a tool developed by the University of California, sponsored by forest industry of Northern California, with support from the California Department of Forestry and Fire Protection (CDF) and the USDA Forest Service (USFS). Using a description of a forest stand, usually developed from forest inventory data, CACTOS simulates changes that occur in Sierra Nevada mixed conifer forest stands. Growth, mortality, and changes due for forest management activities can be simulated. Reporting is done through CACTOS and a series of utility programs.
Be warned that CACTOS has been in development for many years and this version runs in MS-DOS. While it runs fine in an MS-DOS Prompt window under most versions of the Windows operating system, it is still an MS-DOS program and does not take advantage of Windows. The program is command driven and does not support the use of the mouse, nor does it have extensive built in help.
CACTOS is a tool designed for forestry professionals. It is most often used in management planning and for developing Non-industrial Timber Management Plans (NTMP). CACTOS users should understand the input requirements and limits to the program’s predictive ability before using it for management decisions.
Information and and some CACTOS documentation is available on line at:
http://www.CNR.Berkeley.EDU/~wensel/cactos/cactoss.htm
Authors of CACTOS, the California Conifer Timber Output Simulator are Greg S. Biging, P. J. Daugherty, Walter J. Meerschaert, Timothy A. Robards, Eric C. Turnblom, and Lee C. Wensel
CRYPTOS is the Cooperative Redwood Yield Project Timber Output Simulator. It is very similar to CACTOS in design and operation. It is used to simulate young growth redwood stands under management.
Information and some CRYPTOS documentation is available on line at:
http://www.CNR.Berkeley.EDU/~wensel/cryptos/crypt.htm
Authors of CRYPTOS are Lee C. Wensel, Bruce Krumland, and Walter J. Meerschaert, University of California, Berkeley.
Both programs can be downloaded from:
http://www.CNR.Berkeley.EDU/~wensel/cactos/downfile.htm
To help users of the programs we have developed an Excel based Data entry spreadsheet for CACTOS and CRYPTOS. There are also PDF files that document the data format for the Stand Description Files used by the programs, and a description of using the Batch Mode of CACTOS and CRYPTOS.
