| Sheep Vegetation Management Guidelines Appendix 1. Characteristics of Sites Acceptable for Use by Domestic
Sheep for Vegetation Management
Acceptable sites have the following characteristics:
the size of the site is:
large enough to sustain sheep for a set period of time.
has been evaluated for risk to human safety due to isolation or poor
access.
have alternate sites available:
in close proximity to and at greater distances away from the
acceptable project site, should there be a need to relocate the flock due to changes in
vegetation or carnivore interaction, respectively.
the target vegetation complex is:
palatable to domestic sheep;
present in sufficient amounts and adequately nutritional for domestic
sheep;
sprouting at a time that is adequate to sustain sheep for a set
period of time;
ideally less than l m in height (although some species, such as
fireweed, taller than 1 m may also be adequately palatable and tender for consumption);
considered for the presence of overgrown brush such as alder that
restricts movement of sheep and reduces flock visibility;
considered for risk associated with the presence of poisonous plant
species;
free of noxious weed species that may be spread by the use of sheep
through improper timing of grazing or movement to uncontaminated sites;
monitored for forage quality and quantity throughout the grazing
season; and
composed of the appropriate age and species of conifer crop seedlings
for sheep browsing.
the topography is such that:
the amount of slash present does not impede sheep movement;
the slope gradient does not impede sheep movement (overall, slopes
are < 50%);
the ground is not so wet that it restricts sheep or personnel
movement, endangers the health of the sheep, or allows unacceptable damage to local
habitats; and
slope and soil types do not contribute to excess erosion, runoff and
soil compaction.
the water sources are:
suitable in quality and quantity, or a sufficient amount can be
transported to the site for sheep use; and
if they are used for human consumption, are safe from being
contaminated by sheep or sheep feces.
riparian management areas (RMA) are identified:
staging sites can be identified and be available for arrival and
departure of sheep.
access by roads and bridges can be identified and are in a suitable
condition.
the presence of carnivores and key ungulate species and their use of
the area are minimal and do not fall into categories summarized in Appendix 2.
