Term sometimes applied to old, relatively untouched forest rich in biodiversity. May also be referred to as High Conservation Value Forest (HCVF), pristine or natural forest.
Property of paper that minimises the "show-through" of printing from the back side or the next sheet. A paper with low opacity is more transparent.
