If native species and introduced non- <br /> i nvasi ve seed sources are not avai I abl e, protective matting that will hold <br /> and foster the development of native cover from ad acent seed sources <br /> should be used. onti nuous mai ntenance must be empl oyed unti I the <br /> sel ected sped es have matured and are no I onger suscepti bl e to competi ti on <br /> f rom i nvasi ve pl ants. f no J ternati ve to the use of i nvasi ve seeds and <br /> pl ants i s avai I abl e, i nvasi ves approved on the pl ans may be uti I i ed onl y <br /> wi th stri ct contai nment measures outl i ned i n detai I on the pl ans, i n the <br /> construction sequence and in the maintenance specifications. <br /> • Aquickly germinating nurse crop ofnon-invasive,non-competitive annual <br /> grass species can be used along with native seeding and/or matting. These <br /> temporary systems should be pl anted at mi ni mal density so that they do <br /> not i nhi bit the growth and establ i shment of the permanent,native species. <br /> (See the plant chart in Table 6.1 La for recommended native and nurse <br /> crop species.) <br /> • Seed bed preparation is key to successful establishment of seeds. Particular <br /> care shoul d be to en, however,when wor i ng i n wetl ands, ri pari an areas, <br /> or floodplains due to their sensitive nature.
