Ecological Site Inventory

The purpose of Technical Reference 1734-7, Ecological Site Inventory, is to identify the procedures for completing an ecological site inventory and to describe the technique used by the Natural Resource Conservation Service (NRCS) to document and describe ecological sites. These procedures were derived from the NRCS Rangeland Ecological Site Inventory procedure as described in their National Range and Pasture Handbook. Information was also adapted from the NRCS National Soils Handbook and BLM Technical Reference 1737-7, Procedures for Ecological Site Inventory—With Special Reference to Riparian-Wetland Sites. Technical Reference 1734-7  replaces previous guidance found in BLM Manual Handbook 4410-1.
