Reclamation of wetland areas <br /> require somewhat different practices than other sites. Planting <br /> seed in wetland areas is probably the least successful method for <br /> establishing vegetation. The most successful is to save the <br /> existing native vegetation (e.g. rhizomes, tuber, organic soil, <br /> etc. ) and respread this material. This method is usually quite <br /> successful on areas with short term construction (1 month or <br /> less) . Planting live plant material would be the best choice on <br /> construction areas that require longer duration than one month. <br /> HOW TO SEED: Drilling the grass seed is the best method. A <br /> drill provides more uniform depth of planting and better soil-to- <br /> seed contact. The suggested planting depth for grass seed ranges <br /> from 0. 5 to 1 . 5 cm (0. 2 to 0. 6 inches) . The heavier the texture <br /> of the soil the shallower the seed must be placed within the <br /> suggested planting depth. Planting depths of 2 . 5 cm (approx. 1 <br /> inch) or greater results in no grass emergence or plants that are <br /> so weak survival is very poor. <br /> Broadcasting the grass seed on the surface is a common practice <br /> and can be fairly successful if done properly. Also hydro <br /> seeding is used quite often on areas that are too steep for <br /> conventional equipment . Both hydro seeding and broadcasting seed <br /> on the soil surface requires twice the seeding rate per acre that <br /> drilling grass seed requires. In addition, after the seed is <br /> broadcast on the surface, the seed needs to be lightly mixed into <br /> the soil with a harrow and then rolled with a roller or <br /> cultipacker to obtain a firm soil surface and good seed-td-soil <br /> contact. on steep slopes harrowing and/or rolling is not <br /> possible. In these cases, tracked equipment run u� and down the <br /> slope will provide adequate seed incorporation and firming of the <br /> seedbed. Make sure the entire area has track to track coverage. <br /> MULCHES : Mulches can be a real benefit to aid in retaining <br /> moisture . At this point, straw or weed free grass hay would be <br /> the mulch of choice. However, it should be pointed out that the <br /> seeding (hydro seeding) and the mulch operation is a separate <br /> operation. These separate operations ensure good seed to soil <br /> contact and adequate mulch coverage. The straw needs to be <br /> crimped into the soil using a disk to prevent the mulch from <br /> being blown away by wind. The disk should be set in a manner <br /> (minimum or no disk angle) to minimize soil movement since <br />
