BLM OR Timber Production Capability Class Polygon Hub

공공데이터포털

TPCC_POLY: Timber Production Capability Class (TPC) shows areas of BLM-managed lands in Western Oregon that are classified according to the physical and biological capability of the site to support and produce forest products. This data was generated from a variety of data sources over a relatively long period of time. Accuracy of the data, relative to related data and current versions of source data, may be highly variable. Site specific questions of scale and accuracy should be directed to the TPC data steward. This data has been edited for public release.

BLM OR Forest Operations Inventory Vegetation Publication Hub

공공데이터포털

FOIVEG_PUB_POLY: Forest Operations Vegetation Inventory Polygon feature class is a forest centric classification of vegetation with polygons that cover 100 % of western Oregon BLM lands. It describes forested lands in great detail and non-forest lands with broad and general classifications. For a complete description of this data and its structure see the FOI Vegetation Spatial Data Standard.

BLM OR Treatment Project Areas Polygon Hub

공공데이터포털

TRT_PROJ_POLY: This dataset represents project areas for land treatments. Treatments for this purpose are defined as human alterations to the landscape for the purpose of natural resource management including; use, enhancement, and protection. Treatment types include Prescribed Fire, Biological, Chemical, Harvest, Mechanical, Revegetation, and Exclosure/protection. A treatment project area represents a larger area that groups together one or more related treatment activities. Examples include: a timber sale that includes many separate harvest polygons, thinning treatments for a resource area for a fiscal year, and reforestation treatments for a specific area.

BLM OR Site Potential Tree Height Featureclass Hub

공공데이터포털

SPTH_POLY: The Site Potential Tree Height (SPTH_POLY) dataset represents spatial location and basic information about the average maximum height of the tallest dominant trees (200 years or older) for a given site class in Western Oregon. Site potential tree heights generally range from 140 feet to 240 feet, depending on site productivity.

BLM OR LWC Management Polygon Hub

공공데이터포털

LWC_MNGMNT_POLY: This polygon feature represents the spatial extent and boundaries of BLM Lands with Wilderness Characteristics with management decisions. This dataset also also provides BLM and the public with information about naturalness, opportunities for solitude and/or primitive recreation, supplemental values and proximity to Wilderness Areas or Wilderness Study Areas.
