Vegetation cannot be expected to afford protection to stream banks of high velocity or frequently flooding streams. It can supplement masonry channels above the active water line or on small streams and ditches it affords the necessary protection for stabilizing banks. I. Site Preparation - -A. -In flp -n areas -spoil should be "spread and Uariks :graded so that they can be -seeded and maintained -with-conventional equipment. ' B. Wooded areas are difficult both to seed and maintain. Where possible large trees adjacent to streams should be left as they help to shade out low growing woody vegetation and sprout growth that clogs channels. C. Complete seedbed preparation is always desirable. In wooded areas it is often necessary to seed on freshly excavated, scarified spoil and banks. II. Lime and Fertilizer A._ Open areas that can be graded and prepared for permanent maintenance should have the same lime and fertilizer treatment as prescribed for Permanent Seeding of Critical -Areas. B. For excavated channels in wooded areas 10-10-10 fertilizer should be uniformly spread over the disturbed areas at the rate of 1,000 pounds per .acre within the same day the excavation is made. III. Seeding Seeding at the following rates and dates per acre will be made on open graded areas as prescribed for Permanent Seeding of Critical Areas. On wooded areas that are inaccessible to seeding equipment, seed will be uni- formly broadcast on the disturbed areas within the same day the excavation is made. September 1 - March 31 Domestic ryegrass - 20 lbs. KY -31 fescue - 15 los. Redtop - 3 lbs. Reed canarygrass - 15 lbs. Sericea lespedeza - 20 lbs. (hulled and scarified) April 1 -October 31 German or common millet - 15. lbs. Ky-31 fescue - 15 lbs. Redtop - 3 lbs. Reed canarygrass - 15 lbs. Sericea lespedeza - 20 lbs. (hulled and scarified) Reed canarygrass should be omitted from mixtures used on intermittent streams or streams of lour velocity. 31 Mixtures prescribed for Permanent Seeding of Critical Areas may be substitued dor the above on open graded areas. IV. Mulching and Maintenance Same as Permanent Seeding for Critical Areas on accessible open areas. . 1 32
