Pinckney Island National Wildlife Refuge will be closed Tuesday as officials tend to dead trees in areas of heavy public use.

Drought conditions over the past few years and saltwater intrusion has caused a number of large trees to die, according to a news release. The trees are along the entrance road, parking lot and trailhead, and create a hazard to refuge visitors.

Certified chainsaw operators from the refuge's wildland fire crew will do the work, which is expected to be finished in one day. The entrance gate will close at sunset Monday and re-open at sunrise Wednesday.
