As previously reported elsewhere, palm trees have been known to 'pop' off their bases. The 'popped' palm shown in the accompanying image is located nearby a major A1A roadway here in Stuart, FL, and was also a hurricanes (2004) casualty with tree swept away into a neighboring scrub-brush area. The 'popped' palm-tree stumps have an interior depression that can hold rainwater or environmental debris.
Another image shows a cut palm-tree stump from a tree that began to blacken and die following low-temperature change time-period last year.
