I don't know where she read it but the missus said 2025 isn't a mast year in the UK but a quick Google says it definitely is. I will question her googling skills later.Saga Lout wrote: Mon Sep 22, 2025 11:15 amWhat is a mast year? How and why it happensCount Steer wrote: Mon Sep 22, 2025 10:36 am ...
Acorns!! Never known a year like it. Have swept umpteen kg of them up and put them in the garden recycle several times. Had to keep some back each time because if the wheelie bin's too heavy they, sometimes, don't take them. (I assume people try and get rid of soil in them).

"One of the main theories for this behaviour is ‘predator satiation’. Take oak and beech as an example again. Animals like squirrels, jays, mice and badgers feed on the acorns and beech nuts. When the trees produce smaller crops for a few consecutive years, they are in effect keeping the populations of these animals in check. But during a mast year, the trees produce more food than the animals can possibly eat.
"This abundance causes a boom in populations of small mammals like mice. More importantly, it guarantees some will be left over to survive and grow into new trees. Mast years have a major evolutionary advantage for the tree. Producing nuts is costly work and slightly stunts the tree’s growth, but as it tends to happen every 5-10 years, it’s worth the payoff for some of the crop to germinate into new saplings."
Edit: it appears she forgot to specify 'UK'.
