It is often couched in the context of issues like, biodiversity, large mammal populations and human populations. capacity (or grazing capacity) of the land. The grazing capacity of an area is influenced mostly by availability of water for grass growth and the condition of the herbaceous layer. Stocking rate refers to the actual number of animals grazed, which may not match forage production. Stocking rate & carrying capacity . To use the resources below, you will need to know the number and type of livestock you plan to graze, for how long, and the approximate amount of forage you have available. Stocking rate is generally expressed as animal units per unit of land area. The paddock is carrying 10 x 60 = 600kg/(2 hectares) which equates to 300 kg per ha and divide by 50 (DSE value) giving you 6 DSE per hectare. In this article I give my views and understanding of Carrying Capacity and Stocking Rate. CARRYING CAPACITY AND STOCKING RATE CENTRAL ORGANIZING IDEA: The number and kinds of organisms that a system will support is complex. In adaptive management, trends in vegetation change are used to adjust the stocking rate of an area according to the management objectives of that area. There are two main types of carrying capacity—long-term carrying capacity or short-term carrying capacity, otherwise known as forage or dry season pasture budgeting. A major driver of natural resource condition trend is the level of total grazing pressure over time. When matching grazing pressure and carrying capacity, the goal is to devise a management system that will optimize animal and forage production over the long-term, rather than attempting to maximize either factor by itself. Carrying Capacity CARRYING CAPACITY REVIEW Spektrum Review PCC 2018 ABSTRACT This report was commissioned by Landgate to reassess the Potential Carrying Capacity of the majority of the leases in the Kimberley, Pilbara and Southern Rangelands. can also be used to determine initial stocking rates. Stocking rate is how many animal units (AUs) of livestock are grazing or using the land in a certain period. Therefore this level of stocking will not greatly harm land condition; it is a risk-adverse approach to managing stocking rates. The long-term carrying capacity of rangeland refers to the average stocking rate a given amount of land can support for several years without damage to that resource. Carrying capacity is the stocking rate that achieves a targeted level of animal or economic performance over a defined period of time with- out causing deterioration of the pasture ecosys- tem. Concept Abbreviation Definition Animal unit AU 1,000 lb. Evidence suggests most don’t really understand stocking rate & carrying capacity? Carrying capacity refers to the forage-produc-ing capacity of various pastures. Stocking rate, defined as, the number of animals allotted to an area for a given length of time is one of the most important grazing management tools a rancher or land manager can manipulate, regardless of the grazing system, vegetation type or kind and class of livestock. Both involve matching pasture supply to cattle feed intake requirements. Carrying capacity in terms of the animal unit (AU) concept. This AUM was established to be 800 lbs of forage on a dry weight basis (not green weight). This report provides the updated potential carrying capacities, methodology used to calculate these and … of dry forage Animal unit month AUM 780 lbs. Carrying Capacity with Sheep How many sheep can you raise per acre? Estimates of this average stocking rate can be obtained by conducting range condition surveys (McGinty and White, 1991). This stocking strategy is based on an assessment of expected market conditions and rangeland capacity for sustainable livestock production, often referred to as grazing capacity or carrying capacity. QUICK DEFINITION: Stocking Rate is defined as the amount of land allocated to each animal for the grazable period of the year. Carrying capacity is the stocking rate that achieves a targeted level of animal or economic performance over a defined period of time with-out causing deterioration of the pasture ecosys-tem. The AUM provides us with the approximate amount of forage a 1000 lb cow with calf will eat in one month. cow with calf Animal unit day AUD 26 lbs. Estimating the carrying capacity of your land and stocking according to it reduces these risks. The calculated carrying capacity (CC) value for the district ranges between 0 and 1 TLU ha −1 year −1 (1–21.7 ha TLU −1 year −1) with average value of 0.3 TLU ha −1 year −1 (4.9 ha TLU −1 year −1); while, the existing stocking rate has become 5.4 TLU ha −1 year −1 (0.18 ha TLU −1 year −1). A sustainable stocking rate is one which does not degrade the natural resources or permanently reduce pasture productivity as a result of overgrazing, species loss and weed growth. Corresponding Author. Table 1. Managing grazing pressure so that a negative trend in condition is avoided requires an understanding of the carrying capacity of your property and individual paddocks and how these differ to stocking rates. The central, east, southwest, northeast, and south-central regions were above their carrying capacity while the Panhandle, Sandhills, and North Central regions were below their carrying capacity (Table 1). The issue is not just numbers, but equitability among secondary producers, sustainability of the use or values, and remediation of … Carrying capacity, tourism Carrying capacity is a concept that has been widely applied in tourism and recreation studies since the 1960s, although some authors trace its emergence to as far back as 1930. Carrying Capacity is how it should be ideally. Another way of calculating the current stocking Calculating the long-term carrying capacity provides an indication of the safe stocking rate under a set stocking regime and provides a benchmark for projections, forecasting and ongoing management. If you have livestock, or plan on running livestock on your property, it’s important that you understand how many head your property can support, known as your property’s Carrying Capacity . Stocking rate can be calculated from the number and type of grazing animals, and there should be an allowance for native and feral herbivores. Carrying capacity is how many animals your pasture can support in a period of time. 1 AU / 15 Acres How many cows will your land support in Texas? Carrying capacity is essentially the stocking rate that is considered sustainable in the long-term (5–10 years) and relates to the number of livestock that may be maintained on an area of land on an ongoing basis. For sustainable pastoralism, stocking rate must be less than the seasonal carrying capacity of the pasture. It has been defined as an ox which weighs 450 kg and which grows at 50 g per day on a grazing field which are 55% digestible. They are actually two very different measures of how things are at a point in time. Some of these regional differences can be explained by animal movements during the production year. A critical factor to evaluate is how well the stocking rate agrees with the carrying capacity of the land. Carrying capacity refers to the forage-produc- ing capacity of various pastures. Carrying capacity and stocking rate. Fact Sheet 788 Understanding Pasture Stocking Rate and Carrying i.e. Resources for Calculating Stocking Rate and Carrying Capacity. Spektrum consulting was commissioned to complete this review. stocking rate As long term carrying capacity is looking for the average number of animals for a long time period it needs to take into account that there will be poor pasture growth years. Carrying capacity is the stocking rate that is sustainable over time per unit of land area. Stocking rate is the number of animals a land manager places or maintains on a piece of land over a specified period of time. carrying capacity of grazing animals on rangelands. Search for more papers by this author. It takes into account the mix of land types, their condition, the climate and animal production and land condition objectives. A term that is used to help understand and estimate forage requirements is the animal unit (AU) concept (Table 1). In particular how they’re closely related to each other and the importance of considering rainfall when… It was standardized to the 1000 lb cow with calf when they were the most prevalent on rangeland. Carrying capacity is a measure of grass or forage available. Page 1 Carrying Capacity Factsheet CALCULATING THE CURRENT STOCKING RATE EXAMPLE. Stocking rate is how things are, good, bad or ugly. Improved Utilization of Pond Carrying Capacity by Increasing Initial Stocking Rates and Subsequent Stock Division 1. Thus, carrying capacity is set by mother nature, through soil and climate characteristics; stocking rate is set by humans, through livestock or wildlife management.
