Pinecones were everywhere.
According to Menotomy Rocks Park, A Centennial History by Don Mattheisen, White Pines were planted after a devastating gypsy and brown moth invasion in 1902. It was hoped that the needles would not interest these hungry pests. In any case, no such massive invasion of destructive moths recurred then or now.
As to the unusual abundance of pinecones, recent high winds might have played a role in bringing them down, but could not explain why there were so many on the trees in the first place. Perhaps the White Pines planted in the 1900’s were approaching the end of their natural lives and providing for the perpetuation of their species. Or newly abundant rains the last few years had created favorable conditions for baby trees. Squirrels seem to be going after the seeds already.
There are places in the Park where many young evergreens all seem to be about the same height. I will keep an eye out for more patches of young trees springing up, especially where sunlight reaches the forest floor.
