Are there More trees now

Yes

The Society of American Foresters (SAF), the national scientific and educational organization of the forestry profession, has compiled a "top ten" list of forestry-related advances in the United States over the past century.

According to the SAF, "the country has more trees now than it did in 1920 on approximately the same amount of forestland. It also has the largest legally protected wilderness system in the world, while at the same time sustaining a highly productive and efficient wood products industry."
