Infected pine trees that were cut down earlier this week are seen at Rollins Park in Concord on Thursday. About 200 red pines in the South End park are infected with tiny, invasive bugs called scales and were expected to die this year. The trees are being harvested along with an adjacent plantation of white pines.

The work will continue next week. It was stalled amid the warm weather to avoid heavy equipment damaging the muddy site.
