<br /> <br />a <br />" ~) <br />...-) <br /> <br />SUMMARY AND CONCLUSIONS <br /> <br />~ <br />~ <br /> <br />The purposes of this appendix are to describe the current <br />conditions and problems related to watershed management, to <br />describe the remaining job needed and to quantify projected <br />trea tment by time frames, ' <br /> <br />Two programs are considered; one to meet Office of Business <br />Economics-Economic Research Service (OBE-ERS) projections, the other <br />an extension of the 1965 level of expenditures called the Going <br />Program. These programs are also discussed in the Land Resources and <br />Use appendix. Each program provides both production and the pro- <br />tectiqn required to meet that production and cannot be logically <br />separated'into production and protection components because the same <br />treatment and management measures are for both purposes. The program <br />needed to meet OBE-ERS requirements is the principal program described <br />in this appendix, Practices projected by time frames are described <br />by subregions and land resource groups. <br /> <br />Needed treatments are expressed on an acreage basis in the <br />tables of Estimated Needs, Program Quantities and Co.sts. These tables <br />show the amount of each land resource group that has been treated <br />by 1965 and that projected for treatment during the 3 time frames <br />under OBE-ERS and Going Programs. Estimated installation and annual <br />operation, maintenance and replacement costs are given and the totals <br />for each subregion were broken down by federal and non-federal <br />expenditures. <br /> <br />Approximately $11 million annu;l damage results from watershed <br />problems; $1 million from erosion, $5 million from flood and sediment <br />and $5 million from fire as of 1965. <br /> <br />About 11.5 million acres of forest and range, cropland and urban <br />lands will receive some type of watershed treatment to meet the OBE- <br />ERS demands. An additional 72 million acres will be subjected to <br />secondary influences through management. <br /> <br />The more important treatments needed to meet OBE-ERS on forest <br />and rangelands are: seeding, 2.4 million acres; brush and weed control, <br />3.7 million acres; sheet, rill and gully control, 660,000 acres; <br />tree planting, 144,000 acres; road and trail stabilization, 6,700 <br />miles; gully stabilization, 7,000 miles; fencing, 21,000 miles; <br />diversion structures, 2,000; and 1,000 sediment and debris basins. <br /> <br />
