original andrews GIS metadata (Word doc)
These codes are not documented and appear to have some errors, including null values for areas within the Andrews. Some of the values were identified by the Willamette National Forest GIS specialist.
Year of Origin for both natural and managed stands. The year of origin may indicate when a managed stand was certified as reforested. It does not take into account the age of seedlings if planted. Some units may have needed up to10 years to be certified. A value of 0 may indicate no-data.
Willamette NF Data Dictionary
predominant size class of trees MOMS - Mature and OverMature Survey (Willamette Natl Forest 1/91) was a stand condition mapping and old growth inventory project accomplished primarily by means of aerial photo-interpretation. Size class 5 from MOMS was redefined into size classes 5.1 and 6.1 using regression equations of crown diameter to predict size class. NOTE: THESE ARE VERY APPROXIMATE

original andrews GIS metadata (Word doc)
habitats with distinctive features that occur in a stand which may be important when considering mgmt practices Codes: Use this field to capture details about the stand such as presence of a landslide or bog. When multiple habitat features exist in a single stand, the dominant unique feature is attributed.
