Ponds and swamps: If you conducted a ground-based survey of this stand and wanted a TIPSY yield prediction for it, you would probably type out this small pond. Thus, you would not need to apply OAF to the predicted yield to account for the pond area. However, if you were working off of the typical forest cover inventory file, this pond would not be identified. Thus, you would need to apply an OAF to the predicted yield to account for the pond area. So, depending on the resolution of your data, some adjustment to predicted yield may be required to account for yield losses due to small water bodies, like this beaver pond in a young lodgepole pine stand. TIPSY assumes that, whatever the density, there are no large holes in the stand.
