This is actually not true, the amount of forest land has been stable for about 100 years. Most of the decline is in the 19th century as population expanded west.
Land dedicated to farming has also declined for the last ~75 years. Peak was 1954 with about 1.16 billion acres. It is down to about 875 million acres.
