I've had another wee look and some things you might like to consider come to mind in your descriptions of wood.
Oak: presumably you mean the white oaks, not red oaks, which are not suitable for either cooper work or exterior woodwork.
Mahogany: which ones? the Swietenia and Khaya genera are not the same, although they belong to the same family.
Maple: hard or soft? There are about 70 species within the genus Acer.
Elm is native to Europe as well as North America, but it's a different species.
Redwood: do you mean Pinus Sylvestris (aka Scots Pine), a Sequoia or a Sequoiadendron? Presumably the first suggested which, if that's the case, is not native or indigenous to North America, but it is native to Europe and Asia.
It may be worth considering being a little more specific about which wood you are describing when you suggest its uses or its native range. For instance, when you say mahogany, consider appending the Latin binomial name, e.g., Khaya ivorensis and/or Swietenia macrophylla so there is no ambiguity in what follows, assuming the rest of the description is accurate of course. In my mind there is a difference in the working properties, appearance and perhaps even some of the uses that South American mahogany or African mahogany might be put to. In other words, not all mahoganies are the same. Slainte.
