'_ ~ '. In order to 'consider all shrub establishment technologies, concentrated seeding of shrubs is <br />included as an optional method to~be used for establishment of shrub islands~or groupings. <br />This will be used. in addition to the mechanical or, hand planting of seedlings in concentrated <br />' ~~are~as. Seed Mix No. 6 ITable'22-6) lists'the shrub species to be used in seeding these areas. <br />' All species are native to the site. The seed will .~be broadcast on 1a ~~"roughened~~ seedbed ~~ <br />prepared by disking. ~Ii [he soils are not excessively rocky, the.site may be harrowed to ~aid,in <br />lightly covering the. seed. If harrowing is not possible; seeding of these sites should be <br />delayed as late in the seeding season as practical. This will allow the anticipated .snow cover , <br />and fieezing'and thawing `to aid in covering the broadcast seed in areas which cannot be <br />• . harrowed. Drill seeding will be considered, as ari optional seeding method when applying this <br />mix. ,The shrub seeding areas will~not be seeded with the permanent mix, while disking will , <br />~~. suppress volunteering species present ~on .the replaced, topsoil..
