Entering information into the Design screen
There are some
things that you will need to know before using this program.
A. State � This program was designed using those tree and shrub species
which are approved for conservation plantings by the state Natural Resources
Conservation Service (NRCS) offices in Colorado, Montana, Nebraska, North
Dakota and South Dakota. Therefore, the choice of tree and shrub species is
slightly limited. If you are from a different state, or your desired species
does not appear in the species list, choose another species with similar
characteristics such as form and growth rate.
