Watch For Fallen Cherry Trees in Grazing Areas

By Andi Anderson

Farmers are reminded to stay alert for fallen black cherry trees in grazing areas, especially after storms. Black cherry trees, common along fence lines and forest edges, can pose a serious danger to livestock when their wilted leaves are consumed.

Wilted black cherry leaves release prussic acid — also known as cyanide — which can be deadly. Animals such as cattle and sheep that eat these leaves may show signs of poisoning within just 15 minutes.

Symptoms include excess salivation, labored breathing, and convulsions. Unfortunately, due to the rapid onset, farmers often find dead animals without observing warning signs.

The lethal dose for a 1,200-pound cow is between 1.2 to 4.8 pounds of wilted leaves. For a 180-pound sheep, the fatal amount is only about 0.18 to 0.72 pounds.

The risk depends on several factors like the season, moisture conditions, and how long the leaves have been wilting. The danger reduces as the leaves dry out completely.

Black cherry trees grow quickly but have weak upper limbs and shallow roots, making them prone to falling during storms. They are also susceptible to internal decay, increasing the chances of breakage.

Farmers are urged to inspect pastures and fence lines right after a storm to check for fallen cherry trees. Removing downed trees promptly can prevent accidental livestock poisoning.

This summer alone, some farmers have already dealt with fallen cherry trees on their property. It’s a clear reminder that regular checks after bad weather can save livestock lives.

Being proactive with pasture inspections is a simple yet critical step in protecting your animals from this hidden danger.
