' conducted during the same periods as cool season species, except thaz spring seeding may be
extended through May 30th. Seeding activities will be conducted as weather and soil
' conditions permit. Seeding will not be performed when there are more than two inches of
snow on the ground. Drill seeding may be employed when slopes are less than 40 percent and
where soils ate not excessively rocky. Drills will be adequately equipped to aceutately and
evenly distribute the seed mixture at proper seeding depths.
Broadcast seeding rosy be performed on all slopes and on all soils regardless of percentage of
rock canposition. Broadcasters may be humarr-powered or machine-powered as long as they
' are properly equipped and are capable of distributing seed evenly az the requited rates.
Broadcasters mounted on ATVs are particularly effective in remote and difficult terrain.
Broadcasting will not be performed when surface winds prevent the even distribution of seed.
When land imprinting is used to establish surface roughness in conjunction with broadcast
seeding it will be performed following planting operations. Land imprinting will be performed
preferably when soil moisture conditions are medium to high. Moist soils retain imprinted
' shapes better than dry soils. Lnprinting excessively wet soils will be avoided to prevent
unnecessary damage to soil structure. This sequencing and timing enhances the effectiveness
of land imprinting. Land imprinting will firm the seed bed and will ensure good soil to seed
' contact, which is essential to enhancing gemrination rates. When land imprinting is used, other
surface operations designed to cover broadcast seed will not be necessary. if land imprinting is
not used, the surface may be raked, chained, harrowed, or otherwise cWtipacked to cover and
' firm broadcast seed into the soil. Performance of these follow up procedures will be at the
discretion of American Soda. When soils have been recently disturbed prior to seeding, natural
particle movement occuring from wind or in response to rainfall or snowmelt is expected to be
adequate to cover the seed and establish adequau soil contact for germination.
Mulching involves the application of plant residues or other suitable materials to the soil
surface. The purpose of mulching is to conserve moisture, prevent surface compaction or soil
crusting, control weeds, aid in establishing plant cover, and reduce erosion and runoff thereby
protecting the quality of surface runoff. MWching may be necessary where there is a wind or
water erosion hazard, on sails with low infiltration rates, om critical areas, on sites where
annual precipitation is less than 12 inches, or on slopes that are greater than 3h: I v.
1 Hay and straw mulches will be applied at ffie rate of approximately 2 tons per acre. MWch may
be spread by hand or mechanical methods. MWch materials will be evenly and uniformly
distributed over the site to be treated. MWch materials will be free from mold, fungus and
noxious weeds. When native hay is used it will contain the same plant species as are being
used in revegetation seed mixtures or it will be free of seed. Small gran straw used for mWch
will be seedless. Specifications for native hay or straw mWc6 materials will require that az least
509b of the material by weight is greater than or equal to 10 inches long.
To realize maximum effectiveness, mulches will be crimped, netted or tackified using standard
' accepted practices. The type of surface roughening, seeding operations and mulching methods
including anchoring practices to be used for revegetating an area will determine the sequence of
operations. The goal of revegetation operation sequences will be to maximize roughness,
provide optimum planting depth for seed placemen4 and promote even distribution of well
anchored mulch. Different soil types will react uniquely to different treatment combinations
and sequences. Evaluation of soil responses and vegetation establishment and growth to
various combinations of methods will allow sequencing to be tailored to the site and soil types.
Generally, operations will be performed io an order which maximizes the effectiveness of all of
the combined treatments. Normally, planting will be performed after surface roughening and
