Here's a breakdown:
Animals that won't eat it:
* Livestock: Star thistle is toxic to horses, cattle, and sheep, causing liver damage and even death.
* Most native wildlife: Many native animals avoid it due to its prickliness and potential toxicity.
Animals that may eat some:
* Goats: Goats are known to eat a variety of plants, including some weeds. While they might nibble on star thistle, it's not a preferred food source.
* Sheep: Some sheep breeds might eat star thistle, but only when other food sources are scarce. However, this is risky due to the plant's toxicity.
Controlling star thistle:
* Biological control: Some insects and fungi can be introduced to help control the plant.
* Mechanical control: Pulling, mowing, and tilling can help manage infestations.
* Chemical control: Herbicides can be used, but need to be applied carefully to avoid harming other plants.
Important Note: It's crucial to consult with a veterinarian or agricultural expert before letting any animal graze in an area with star thistle.
