We are following a two-step <br />process. If necessary, follow-up steps will be taken to maintain control. <br />Step One: <br />We are actively removing Russian olive and tamarisk. <br />Step Two: <br />With the approval of this Technical Revision, we will reseed the area with species accepted by <br />the Corp. The attached list includes all native plant species. The intent is to drill seed if ground <br />conditions allow. Otherwise, broadcast seeding will be used at twice the drill seeding rate. <br />Table 1. Rettegetation seed mix. <br />Common Nares; <br />sclentifle Name <br />i'15I1.

The cross -hatch areas are the wetland removal areas where Corp. <br />approval was obtained and where the above list of plant species will be seeded. We estimate the <br />Corp. jurisdictional area to be less than two acres. <br />
