How Much Land Do Alpacas Need? Alpacas Per Acre

Land is the first thing to check before buying alpacas, and the answer is usually given as alpacas per acre. The published figures sit in a fairly tight band, but they all depend on the same thing: how much good grass your ground grows.

Alpacas per acre: what the guidance says

• British Alpaca Society: typically 4 to 6 alpacas per acre. It says the stocking rate depends on the amount of grass, its quality, and how often and how hard it's grazed.
• Cornell Cooperative Extension: 3 to 4 adult alpacas per acre, the most cautious figure.
• UMass Amherst Extension: a rule of thumb of 6 alpacas per acre, depending on pasture quality.

Start with at least three

Alpacas are herd animals and the British Alpaca Society says they should be kept in groups of 3 or more (see can you keep just one alpaca?). So the smallest sensible herd needs roughly half an acre to an acre: 0.5–0.75 acre at the British Alpaca Society's rate, or 0.75–1 acre at Cornell's.

Paddocks, rotation and fencing

UMass Extension recommends extra pastures so you can rotate the herd and let grass recover, and says breeders need separate pastures for females, adult males, weanlings and young males. The British Alpaca Society advises picking up dung daily and checking paddocks for poisonous plants.

For fencing, the British Alpaca Society says four-foot sheep fencing with stock netting is usually suitable, barbed wire should be removed, and electric fencing is best avoided. Cornell suggests 4–5 ft. UMass Extension warns against cow fencing whose larger holes let alpacas push their heads through and get stuck.

Work out your own numbers

The alpaca calculator shows grazing land and shelter space for your herd size, in acres and hectares (UK) or acres and square feet (US). Shelter is a separate, much smaller figure: see how much space does an alpaca need?

Common questions

How many alpacas can you keep per acre?

Typically 4 to 6 per acre according to the British Alpaca Society, depending on the amount and quality of grass. Cornell Cooperative Extension is more cautious at 3 to 4 adults per acre, and UMass Extension's rule of thumb is about 6 on good pasture.

How much land do I need for 3 alpacas?

Roughly half an acre to an acre. At the British Alpaca Society's 4 to 6 per acre, three alpacas need 0.5–0.75 acre; at Cornell's 3 to 4 per acre, 0.75–1 acre.

Can alpacas live on less land?

The stocking rates assume grazing provides much of the food. The British Alpaca Society says alpacas need grazing and/or hay all year round, so on less land you'd be feeding more hay and managing muddy, overgrazed ground.

Do alpacas need more than one paddock?

UMass Extension says breeders should expect at least three or four pastures (females, adult males, weanlings and young males), with extra ones to rotate so grass can recover.
