yes. the bark contains a high level of tannin, which keeps bugs out and keeps it from rotting.
the pros of building a floor for a basement out of wood is that if there is some soort of sewage pipe leake then you dont have to pull out the jack hammer or hammer and chisel. the con is termite, ants, insects and, rot
Lumber used to be pressure treated with arsenic - a lethal poison - specifically chromated copper arsenate - which turned the lumber slightly green- but legislation was passed several years ago ( 2003 ) stopping the use of arscenic and going to less toxic substances. Another copper solution called ACQ is used. The copper makes the wood more rot resistant and is toxic to some insect life. Termites would tend to favor untreated wood. While the bottom sill of balloon frame structures may be pressure treated, the framing above the bottom sill is most often not treated. It is too expensive to build structures entirely from pressure treated lumber. The best defense against termites is to keep the wooden parts of the structure well off the soil with stone or concrete foundations and keep those foundation lines clear of flower beds mulched in wood chips so as not to give termite colonies easy access.

Redwood, cypress, and cedar are termite and rot resistant. These are softwoods and may not last as long as hardwoods.
yes. the bark contains a high level of tannin, which keeps bugs out and keeps it from rotting.
Lightweight,dimensionally stable and rot resistant
The disadvantages of Ash wood is that it is not as rot proof or water resistant as other hard woods. If it is left untreated, it will rot quickly.
Western red cedar is a natural rot resistant soft wood.
Hemlock is not very rot resistant.
Cedar doesn't rot because it is water resistant and if it isn't sealed it will last you pretty long. It can last up to 8 years if not sealed *After "8 years" then what? Cedar rots like any other wood if you wait long enough. How long depends on factors such as how much water can get trapped where two cedar parts touch or how severely it is constantly dried out (dry rot).
Jarrah and Teak last approximately 50 years, and Jarrah is fire, rot and termite resistant, so is a good choice for durability. Other common woods used are Pine, Redwood, Roble and White Cedar. further information on the woods can be gained at http://www.outdoorlivingideas.com/woodtypes.html.
Red pine is one of the most used woods in the country. It is not naturally rot resistant, however, it can be protected and treated to ensure that is it can resist rot.
