Interpreting parameter estimates for nominal variables in stepwise least sq

I have a categorical variable that has 3 categories, when it is reported in the parameter estimates table there are two parameters listed for the variable: Veg type (1&2-3) and Veg type (1-2). If category 1 represents ponderosa pine, 2 grassland, and 3 pinyon juniper, how do I interpret these results?

Thanks in advance for your help.
