4) For reclaimed areas that are severely eroded, identification and
correction of the causal agent(s), followed where necessary by
placement of additional soil reconstruction materials and either
conducting partial or complete revegetation operations;
5) Design and construction of additional channels or other structures
to convey concentrated flow through, from or around disturbed or
reclaimed areas. Gullies which are large and can not be readily
routed into existing drainage channels may be shaped into
permanent channels and appropriately protected against erosion;
and
6) Correction of chronic erosion problem areas through topographic
modification including importation, exportation or regrading,
followed by revegetation operations.
Mulch imprinting utilizing livestock or wildlife for repair of rills
and gullies will be performed not prior to one year following seeding (or
one year following placement of live-handled, non-seeded, rotocleared
topsoil) When livestock are used for mulch imprinting, portable electric
fencing will be placed to control the movement of the livestock.
Generally, the extent of an area to be encompassed by the fencing will be
limited to a single erosion control monitoring block as described in the
annual reclamation report. Exceptions to the single block fencing may
occur when the block is of extremely limited size or irregular shape (i.e.,
Moffat blocks 3, 6 and 9 may be combined together or with other blocks).
Once the area has been fenced hay bales will be placed in the rill or gully
and loosened. Additionally, the approved reclamation seed mix may be
broadcast onto the area. Livestock, usually a small group of cattle, will
be released on the area £or a few days to a maximum of two weeks. As the
cattle consume the loosened hay bales, their hooving action acts as an
imprinter disrupting the rill or gully, anchoring some of the hay mulch
into the soil and incorporating the seed into the eroded area.
Additionally, the cattle urine and manure acts as fertilizer promoting new
vegetative growth. To assist in controlling the movement of the cattle
within the fenced area, strategic placement of salt blocks and a portable
water trough will be used.
In using the cattle as a biological imprinter, soil moisture
conditions must be taken into consideration. If the soil is too moist the
imprinting action may damage the rooting system of surrounding vegetation.
If the soil is too dry little or no imprinting action will be evident.
