There has to be a logical reason for the discrepancies.

'During the 1980s, Africa lost an estimated 47 million
hectares of forest. By 1995 another 19 million hectares
had been lost, according to FAO,..
...
In forested areas, patches of logging, agricultural advance
and unsustainable harvesting of fuelwood and non-timber
products fragment and degrade remaining forests.
Fragmentation leads to loss of contact with part of the
ecosystem necessary to maintain regeneration and full
biodiversity. Many species need large and diverse areas.
Others depend on other species, living in the border areas
of the ecosystem or species being hunted or harvested.
Thus, very few entire forest ecosystems, frontier forests
keep existing.

Worldwide, 80% of original forest cover has been cleared,
fragmented, or otherwise degraded in the 20th century. In
the Atlantic rainforests of Brazil, the West African rainforests,
Madagascar, and Sumatra - some of the richest biological
treasure houses of the world - much less than 10% of the
original forest cover is left. There, many populations of
plants and animals are losing their long-term viability through
fragmentation and genetic erosion. A wave of extinctions is
just around the corner - unless "radical" action is taken.

Not according to earlier studies, nor all recent studies.
