How do deciduous trees protect themselves during the seasons?
Deciduous methods: First thing they do is take mobile nutrients out of there leaves and move them into the root system for storage and use next year.
Dropping the leaves helps them shed ice and snow so that weight doesn't build up and snap off limbs.
Methods common to conifers and deciduous:
Removing excess water lowers the chance of having enough freeze and expand breaking the stem.
Removing impurities and air bubbles from the water. Ice usually forms around and a speck of dirt (nucleus) at 0 degrees Celsius but if there is no nucleus ice will not form till -37 (non-nucleic freezing).
The internal clock of the tree and responses to its environment will has a great effect of the survivability of the tree as well ie coming out of dormancy to soon, hydrating then freezing with the next cold snap.
I believe there's others but that's all I remember. Theres lots of summer time protection methods as well I assume you just want the winter ones...
What are the areas of scattered trees and shrubs called?
Scrub country
That's a very original, fitting answer for a non-specific question. It made me laugh, thanks. May I offer the following that the person may fit his situation.
Depending on the land mass by your description of "area":
1. It could be a garden if the shrubs are flowering shrubs and the trees were ornamental or fruit bearing.
2. If the trees are a mixture, that is not of any species of wood for harvesting, and the shrubs are whatever grew and are not cared for, this would best be described as woodland or simply woods. Woods are usually part of farmland in the Midwest or of un-tillable land, sometimes of wetlands.
3. Larger land masses are woodlands or forests, usually having timber and shrubs. Shrubs may be flowering or seedlings that will grow into timber.
4. My grandfather has seen jungles and rain forests in Vietnam with triple canopies of abundant trees and shrubs, vines, plants, grass and weeds. Within these forests one could find clearings for roads, villages and small farms. The vastness of these wooded areas are opposite of our Midwestern states where there are more farmland than woodland.

How does spraying fruit trees with water before the frost comes keep the trees from freezing?
Water keeps trees from freezing because the water releases heat when it freezes. That heat raises the temperature of the tree, the air around the tree and the soil, preventing ice formation in the tissues of the tree.
Cold water should be sprayed on the blossom of fruit trees after frost has occurred but before the sun has risen to melt the frost.
What are some of Rome's plants?
The staple crops of Roman farmers in Italy were various grains, olives, and grapes. Olive oil and wine, outside of direct food stuffs, were among the most important products in the ancient civilized world and led Italy's exports.

A box elder tree (Acer negundo) is known for its rapid growth, typically reaching heights of 30 to 50 feet within 10 to 15 years. Under optimal conditions, it can grow up to 2 to 4 feet per year. This fast growth makes it a popular choice for quick shade, although it is often considered a less desirable tree due to its weak wood and tendency to produce numerous seedlings.

'''Yes''', the American sycamore tree (''Platanus occidentalis'') may be described as poisonous ... to certain plants. Specifically, the tree exerts an allelopathic effect on surrounding vegetation. That effect actually is a germination inhibitor, which keeps plants from maturing into attractive, healthy plants. It's the same effect that black walnut trees (''Juglans nigra'') exert on surrounding vegetation, to control competition.
