Oh yes! Like I told a retired guy who volunteers to work with us when he was talking about his other work in clearing trees: for every tree cut down plant two or three new ones and not just the one.
@val70 I collected some acorns last Autumn, to try to bring them on, but they all disappeared. I'll have another go, with acorns and perhaps "conkers" (horse-chestnut seeds) too, this Autumn.
Sad to learn that one tree has come to the end of its life: the Major Oak in Sherwood Forest.
Already mature when so many younger oaks round it were felled for shipbuilding, it would have been deteriorating for years of course; but those studying and caring for it say this has been hastened by the constant tourist foot traffic around it compressing the soil.
On the other hand a decaying tree does support a wide range of invertebrates, and its decay will return its materials to the soil as nutrients for new ones.
