<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This dataset, compiled from various sources at UNEP-WCMC, shows the original extent of global forest cover before human impact. It is divided into needle-leaf forest (NF), non-forest (NON), temperate, broadleaf and mixed forest (TBMF), tropical dry forest (TDF) and tropical moist forest (TMF). This dataset can be used with the dataset showing current forest cover to identify broad change.</SPAN></P></DIV></DIV>
About half of the forest that was present under modern (i.e. post-Pleistocene) climatic conditions, and before the spread of human influence, has disappeared, largely through the impact of man's activities. The spread of agriculture and animal husbandry, the harvesting of forests for timber and fuel, and the expansion of populated areas have all taken their toll on forests. The causes and timing of forest loss differ between regions and forest types, as do the current trends in change in forest cover. This dataset has been produced from a variety of sources to be used in comparison with the dataset showing current forest cover allowing change over time to be identified.

Records from many different sources were reviewed for inclusion, based on published and peer reviewed scientific literature and outreach to expert knowledge.
A wide range of sources at various scales have been incorporated.. A crucial aspect of the collation of this dataset is ensuring that the dataset is of the highest possible scientific quality through the involvement of the key experts worldwide. This dataset is assumed to be complete at the time of publication.
Data compiled from various sources. A full list of contributors is available from UNEP-WCMC.
