Summary
of Factors to Consider when Choosing the Locations
of Exclosures |
|
|
| |
|
-
|
|
Exclosures should be distributed
to represent all parts of the field. |
|
-
|
|
It is best to stratify a field into two or three units based on anticipated grazing intensity (e.g. more intensive, less intensive, and no grazing). |
|
-
|
|
Since
there should be no yield difference in ungrazed areas, put more exclosures in strata of the field that are expected to be heavily grazed. This will allow for more controls in grazed areas for more adequate statistical analysis. |
|
-
|
|
Avoid placing exclosures where
swathers and combines turn. |
|
-
|
|
The
general location of the exclosures is based on field shape, soil types, topography, and anticipated goose grazing. This step is performed by generating random GPS points. |
|
-
|
|
The specific location of each
paired plot is done in the field. |
|
-
|
|
To avoid subjectivity and increase
the validity of the statistical analysis, exclosure (control)
and grazed plot (treatment) locations should be randomly
assigned. |
