Which of the following may be used to improve livestock grazing distribution on ranges?
|
Hauling drinking water for livestock, early spring burning, changing animal species to better match the topography and vegetation, place salt away from the water.
|
|
A "key area" is one that is selected as a site for monitoring because it is representative of overall range condition, trend and degree of use.
|
True
|
|
Stocking rate is best defined as
|
The amount of land allocated to each animal unit for the grazeable period of the year.
|
|
The stocking rate that produces the maximum animal production per acre is:
|
Called the ecological optimum.
|
|
Utilization: Select the statements that are true.
|
Using predetermined levels of utilization of key species on key sites to set stocking rates is an efficient, but not a high effective approach for grazing administration. A much wider set of interest groups are expressing active interest in the health and management of out nations rangelands than compared to 30 years ago.
|
|
Optimum Stocking rate: Select the statements that are true
|
Maximum gains per ha and per head cannot be achieved at the same stocking rate. Moderate stocking has been found to give higher net economic returns than heavy stocking in many studies.
|
|
Disadvantages of flexible stocking rates: Select the statements that have been proposed as disadvantages for flexible stocking strategies.
|
Management of flexible stocking rates is difficult to implement. It can result in selling livestock on depressed markets and buying on high markets. Forage availability cannot be easily measured or predicted. Producers delay making the decisions to reduce stocking rates.
|
|
Select the stocking strategies that represent viable alternatives for producers.
|
Vary stocking rate to match forage demand with proper use of forage on an annual basis. Stock conservatively so that the range is not overstocked even in fairly severe droughts.
|
|
Match the key species with the kind of animal based on studies in New Mexico.
|

|
|
Match the percentage use for moderate grazing with the range type.
|
30-40= Semidesert grass and shrubland35-45= short grass prairie 40-50= Southern mixed prairie20-30= Alpine Tundra45-55= Tallgrass prairie 50-60= Southern pine forest
|
|
Cattle like to graze away from water and most of their use will be located over 1 mile from the water source.
|
False, cattle will only graze up to one mile from the water source. They are lazy animals who do not like to walk far for water.
|
|
Livestock production from rotational grazing is generally less than or equal to that from continuous stocking at the same stocking rate.
|
True
|
|
The primary problem with continuous stocking (also called continuous grazing) is:
|
Points of livestock concentration receive excessive use.
|
|
Characteristics of high intensity-low frequency grazing are:
|
Have non-use periods of 60 days or greater.Can lead to improved range condition in humid areas.
|
|
Application of grazing systems used which of the following tools?
|
Nutritional management of livestock. proper stocking ratesproper season of grazing pasture size, time, and grazing distributionstrategic deferment
