- Land Resources and Use

The land resource base of the Region appears to be sufficient in
variety and amount to satisfY the projected land use requirements
through the year 2020. There will need to be widespread adoption of
the multiple-use principle in order to satisfY the requirements of all
uses.

The following tabulation shows the majorle.nd use requirements
for the period of study:

Land Treatment and Management

Irreversible losses of the Region's land resources must be mini-
mized to preserve a freedom of choice for future resource users.
Esthetic and environmental factors were of primary consideration in
development of the program. Ideally, the land treatment and management
program should harmonize with all water and related land resource
development programs required to satisfY present and projected demands
within the Region. On an equivalent acreage basis, as of 1965, a
total of nearly 7 million acres of cropland, forestland, rangeland,
and urban and other lands had received adequate treatment. The program
