A massive tree plantation in Pennsylvania has killed over 100 animals, including deer, after a fungus took over the area and killed trees, according to the local animal control agency.

The Pennsylvania Department of Agriculture and Consumer Services confirmed to NBC10 that the fungus is called Myxomatosis, and that it killed more than 50 deer this past weekend in the area.

The department’s director said the deer died due to the loss of soil nutrients, not the disease.

“There is no reason to believe that the deer were killed by the fungus,” said department spokesperson Sarah Richey.

She added that it is not clear why the deer took so long to recover.

It’s not the first time that the tree plantation has killed animals.

In 2013, the same tree plantation caused an estimated 30 deer deaths in a small farming community in Pennsylvania.

The tree plantation was shut down after a large outbreak of the fungus.
