Abstract:
Phygrow is a hydrologic based plant growth simulation model. Phygrow
is intended to produce an available forage production for a site. Phygrow
uses soil characteristics, plant community characteristics, and weather
data for a particular location to predict the forage production. The PHYGROW
system is intended to be a general ecosystem model similar in function
to the work done by The Dynamic, Spatial, Ecological Modeling Team in their
Sage Grouse
Model developed for the US Army's Yakima Training Center. Many of the
growth parameters are from A Wepp
Phygrow will provide hooks that allow for the sage grouse, and the
human activities type models, with a more extensive and more flexible vegetation
and physical process submodel. Internally Phygrow will be primaraly concerned
with ruminant grazing practices with respect to long term viability of
the vegetation.
II. Technical Information
II.1 Executables:
Operating System(s): Release 1.0, and 1.2 have been restricted to the groups associated withthe Department of Rangeland Ecology and Management at Texas A&M University.The Version 2.0 functional group and plant community editors have beengiven a cursory review by other experts within the Rangeland Ecology andManagement Department at Texas A&M. The BLM has also viewed the model.Internal testing is scheduled to begin aroune 2/95.
