Rangeland and dryland pasture Animal Unit Month (AUM) estimations are needed for a variety of conservation planning and data applications. An algorithm based on the data of such a survey was constructed to calculate a normative carrying capacity of each forest stand for grazing sheep and cattle and browsing goats. The number of grazing animals a piece of land can support long term while maintaining or improving the rangeland resources (vegetation, soils, and water) is called carrying capacity.The characteristics of the land, vegetation, and soil determine the carrying capacity… Sample Calculation for Forested Rangelands..... 11 Sample Calculation for Grassland Rangelands..... 14 Literature cited..... 17 APPENDIX 1. and grazing capacity the total dry matter production of each. Research by Botha (unpublished report, 1991), revealed that the index values currently used to calculate the veld-condition score, may lead to either over- or under-estimation of the current grazing capacity. Davidson, A. Nadeau, T. Guyondet, R. Sonier, A. Ramsay, J. Davidson Fisheries and Oceans Canada Gulf Fisheries Centre P.O. Based on the pastoral value, the grazing capacity may be calculated according to formula: G.c. Stocking rate Conversions..... 25 3.

Drought Intervention Hotline: 0800 000 996. of Forage DM . This document describes the methods used by PLFD Rangeland Agrologists to calculate carrying and grazing capacities on public rangelands in Alberta. RESULTS AND DISCUSSION Grassland classification The native grasslands of Naqu Prefecture were subdivided into 4 classes, 10 groups, and 32 types. The grazing capacity of the ranch is estimated to be 89 cows/year, while meeting the concurrent objective of improving range condition. The herd consists of 300 pair of 1100 lbs Angus cross cattle with 15 Angus bulls during July and August. Grazing capacity calculations. This calculation is then compared to a table of values representing each type of animal and their AU equivalencies (for example, an adult horse is equivalent to 1.25 AU). However, it important not to include areas that are outside a realistic grazing distance from water. Online Forage Calculators These calculators explore the number and type of livestock your land can support based on forage need and the forage available. Latest Videos. T o determined the relationship between rangeland condition. 2c). Carrying or grazing capacity (CC) is described as the maximum number of animals that the rangeland can support without depleting the resources of the rangeland such as vegetation and soil (FAO, 1988). The methodology involves the calculation of stocking rate (SR) and grazing capacity (GC) and their comparison. Population structure and grazing capacity of cultivated mussels in Prince Edward Island, Canada L.A. Comeau, R. Filgueira, J.D.P. The only time that the value of veld or grazing directly correlates with carrying capacity is in budget calculations. Animal units (AU) are used to calculate the relative grazing impact of different kinds and classes of domestic livestock and common grazing wildlife species for one month (AUM = animal unit months). 2. Evidence suggests most don’t really understand stocking rate & carrying capacity? In reality, this calculation does not allow carrying capacity to be fine-tuned to a very specific number of animals. If SR equals GC the rangelands are properly grazed, but if SR does not equal GC then grazing is improper and irrational and should be adjusted. Grazing capacity integrated with reforestation..... 24 APPENDIX 3. 4. Tags cattle cattle feed graze lands grazing land management land use.

However, the opportunity to graze ewes on lucerne needs to be compared to other option such as finishing lambs or growing weaners during the summer/autumn months. – pastoral value; c (coefficient) = 0.4 – 0.6 LU/ha (Livestock units per hectare). 3. What we have learned from stocking rate studies. = P.V. Except for the winter season, estimated grazing capacity highly reflects the actual situation in 2004. Distance from water and slope b. Forage demand by grazing animals c. The harvest coefficient d. Stocking rate calculation 5. Stocking rate is how things are, good, bad or ugly. Carrying capacity calculated in this way was found to be a fair reflection of actual observed stocking rates. – represent the grazing capacity; P.V. It also explains the process for map development and related carrying and grazing capacity procedures in GLIMPS. The most accurate method to calculate forage production is the clip-and-weigh method. This correlation is often made by agricultural economists treading on the professional valuer’s domain. Glossary of Terms..... 19 APPENDIX 2. Look for obvious signs of grazing and cattle activity at a number of points away from water and work out the furthest point cattle range.
