Performed by Growers
Part I describes procedures that growers can do, with
or without technical assistance. These procedures include
setting up goose-proof exclosures as outlined in Section
A. Section B describes how to perform the ground truthing
and monitoring of goose activity. Other impacts are
also recorded during field visits such as water damage,
deer/elk grazing, etc. Areas are mapped and delineated
with a hand-held GPS unit.
The primary objective of monitoring goose
grazing is to accurately and reliably measure the impact
of grazing on grain or seed yield. To accomplish this
objective, it is necessary to compare yield from grazed
areas to yield from comparable areas that are not grazed.
Exclosures provide the comparable areas that are not
B: Ground-Truth Monitoring
To document where grazing is occurring,
where flooding is a factor, and to detect any other
potential impacts on yield, ground-truth monitoring
is required. The ground data collection is one of the
most basic methods for gathering field data.
