Botany

I'm looking for the name and a website (or wiki entry) on an ancient form of forestry. It entails cutting the tree down (but not completely) for use as wood source, but leaves enough trunk behind to grow saplings out of. The saplings are pruned until the strongest grows to become a new tree, and the process repeats. I remember reading about this being practiced in England, and it being a multi-generational form of sustainable forestry being practiced even in ancient times. It is still being practiced by a few people today.

Name, and reference site, please.

It has racemes of yellow pea like flowers but I have seen them with pale pink or purple flowers. The leaves are large and pinnate with oval shaped leaflets. I thought is was a Tipuana but apparently it has a different name.

In the city of Sonoma CA, there is a row of trees on 2nd Street that produce a Fall crop of fruit that is chartreuse and yellow . The tree looks like a Cottonwood tree (not as tall) and the fruit resembles a human brain, varying in size from a softball to a large Grapefruit. It smells like a cross between a pineapple and pine tree. I have trepidation about eating this fruit as I cannot find any reference to it's toxic nature.

I know that deciduous trees go dormant in the winter to conserve energy or water, but why do evergreens not have to go dormant in the winter.
