The Full Form of IMPF is Intensively-Managed Planted Forest.

Intensively-managed planted forests (IMPF) are highly-productive plantation forests grown primarily for wood and fibre production. There are currently an estimated 25 M ha of IMPF globally, representing about a quarter of  plantation forests and occupying c. 0.2% of global land area. IMPF are owned and managed at scales which range from large corporate estates of hundreds of thousands of hectares, to smallholders with less than one hectare. The high productivity of IMPF is such that they contribute disproportionately – currently around 40% – to the world’s industrial wood supply. Growing demand for forest products, diminishing supply from natural forests, and the comparative advantage of IMPF in wood and fibre production are promoting IMPF expansion, especially of shorter-rotation IMPF grown primarily for pulpwood. Globally, IMPF expanded at nearly 2% per year in the first half of this decade –  mostly in Asia, Oceania and South America
