Historic preservation is a process that works to preserve, conserve, and protect any objects, landscapes, buildings, or other artifacts of notable historical significance. It applies specifically to constructed or human-altered things, not the preservation of wilderness or forests. Historic preservation has an active educational component, and locations like museums help to preserve documents, tools, and other items too small to be protected as an independent site. Jobs in this field also help to repair damaged items, research the history and methods of their use, create records of historical findings, and otherwise preserve things for as long as possible. For larger areas, such as historic homes or districts, this may involve a significant amount of carpentry, painting, or other household repair work.
