I went for my walk at lunch. Last year the streets under the white oaks were covered with crushed acorns. I didn't see a single one today. The reds and pin oaks have dropped just a few.
This last spring I noticed the lack of catkins (those wicker things oaks shed). Most years they are thick. This last spring there were next to none. This is likely the reason for the lack of acorns. No catkins, no acorns. I just don't know what causes the lack of catkins. And it rained a lot last spring so maybe that kept the oaks from being pollinated well.
