W. Enter the total the score for each row by multiplying the number of answers in each row by the rating factor. Note that the
Score column allows you to enter the Score of the Present System and the Score of the Proposed System, based on the
conservation plan developed.
X.
The Total Score for the Present and Proposed Systems are the sum of their total respective scores, divided by three. This
provides the condition score and rating for both the Present and Planned systems.
: 7 / 3 = 2.3.

score for both systems (present and planned/proposed).
Z.
Calculate a suggested safe stocking rate by the following steps:
1.
Determine the total pounds per acre of available forage by summing the total pounds per acre from for all species that
are desirable forage for the grazing animals to be managed. Low palatable and weedy species that are grazed only
occasionally should not be included.
: 1,500 lbs/acre x 90% = 1,350 lbs/acre.
EXAMPLE
2.
Determine the appropriate Harvest Efficiency (H.E.) for the pasture, based on forage uniformity, and type of grazing
system. The average H.E. for pastures under a moderate management level is 30%. Fields in good condition with a high
level of grazing management may use a H.E. of 40%. Pastures in low condition with poor forage quality should use a
H.E. of 25%.
3.
Multiply the results from 1 above by the results in 2 above to determine the total pounds of available forage.
Example: 1,350 lbs/acre x 30% H.E. = 405 lbs/acre.
4.
Divide the answer in 3 by 915 pounds per animal unit month and enter the results (AUM per acre) on the blank line
provided. Example: 405 lbs/acre / 915 lbs/AUM = .44 AUM/acre.
AA. Make notes as to resource conditions, weedy or undesirable species, or other observations.
