    A volume estimation system for Pinus cooperi was developed, using taper functions. These equations describe the stem shape.  By integrating a taper function, a volume equation is generated. Data from 35 stem analyses were used. Regression techniques implemented in SAS were worked to fit nine volume functions and ten taper functions.  The best volume equation was log(v) = -0.821609 + 0.980899 log (D2H).  The best taper equation was: d2 = D2(1.044093 - 2.832906 +7.624771 2-10.415754 3-4.569118 4) Integration of this equation yields:   which can be applied to predict total merchantable volume inside the bark to any stem height limit and also to predict a bole segment volume.  Tree volume inside bark for the species may be predicted by    which finally results in V = 0.3762987 (D2H).
