Northwest range-plant symbols adapted to automatic data processing.

Abstract

Many range technicians, agronomists, foresters, biologists, and botanists of various educational institutions and government agencies in the Northwest have been using a four-letter symbol list or code compiled 12 years ago from records of plants collected by the U.S. Forest Service in Oregon and Washington, This code has served well as a means of entering plant names on crowded field sheets without requiring a lot of memorization, In this respect it has proved superior to the old three-letter symbol list. Yet, about 400 changes in nomenclature have occurred since 1948 among the plants listed, and increased use is being made of automatic machines for processing data. Therefore it has become necessary to revise the list of scientific names of plants and to adapt the code to machine work.
