"The typical lifespan of a cherry tree is as short as 16 to 20 years. Some species are longer lived than others. Black cherry trees (Prunus serotina) live up to 250 years, although the average lifespan of a black cherry is 100 years. Cherry trees are sensitive specimen trees. They are easily susceptible and invaded by insects and diseases. Cherry trees commonly succumb to diseases such as brown rot, black knot, silver leaf disease, as well as bacterial canker. Insects such as borers, aphids and scales weaken and destroy cherry trees."
The typical lifespan of a peach tree in cold areas is only 10 to 15 years, and up to 50 years in a warm area. So this explains why orchards disappear and get replanted as the tree production starts to decline. I do like the ancient trees, though, especially when they have been pruned and shaped like the one below.
