Why it matters

Silver maple is closely related to red maple and hybridizes with it. Fresh leaves browsed from a living tree are a low risk; avoid piles of wilted leaves.

Signs of silver maple poisoning in alpacas

  • Possible anemia signs: weakness, pale gums, dark urine

If your alpaca ate a lot of silver maple

  1. Remove access and estimate how much was eaten.
  2. Watch for the signs listed above over the next 24–72 hours.
  3. Call your vet if any signs appear or if a pregnant, young or sick animal ate a large amount.
  4. Reduce the plant in your pasture and keep good forage available so alpacas aren't driven to eat it.

Keeping pastures safe

  • Walk every paddock and fence line each season and remove toxic plants, including roots.
  • Never throw garden, hedge or lawn clippings over the fence.
  • Check pastures after storms for fallen branches (cherry, red maple).
  • Buy hay from known sources and inspect it for weeds.
  • Keep pastures well managed — hungry alpacas eat plants they would normally avoid.
