Hello,

I am trying to estimate the historic and present forest cover as a 
percentage of world and regional land area.

If you have accurate information on this topic, please forward it to:

Thank you.  Below find a list of categories I am interested in 
estimating.  Give it your best shot!

Table 1.    Some really rough estimates of forest cover as a percent (%) of land area.

Region                          Dates  1700   1900   1950   1990 

North America                           59     45     39      40
Central and South America               80     70     55      50
Former USSR                             58     55     51      52
Europe                                                30      31
Africa                                                30      24
Asia and Pacific                                      41      35
World Average forest to land area  %                  41      38

Average forest to world surface area %  9.6    7.5    3.9    3.2


Earth surface area: 5.1 x 10(to the power of 12) ha
                    70.8% water => covers 3601 billion ha 
                    29.2% land  => covers 1499 billion ha
                    current (1994) forest area =>  ?  billion ha
