TACOMA, Wash. (AP) — A park south of Tacoma, Washington, is removing 250 Douglas fir trees that are each more than 100 years old after officials found tree-decaying diseases.

KCPQ-TV reports that Pierce County Parks and Recreation officials found the diseased trees after surveying 1,500 trees at Spanaway Park.

Department spokesman Jess Stone says it's not unusual to see trees of this age experiencing some issues with fungi, but the problem is amplified by the lack of tree diversity.

Stone says the tree removal will be spaced out so the scenery doesn't change all at once. Park workers have removed 68 trees so far, and 50 will be removed each year starting in the next.

Trees at two other area parks will also be cut down, but the number is not yet known.
