View submission: do we have more or less trees than we did 30 years ago?

I don't know about stem count, not do I think it's very informative, but the world is currently losing around 120000 km^2 of forest cover per year. Some areas are gaining cover and some are losing cover:  https://www.science.org/doi/full/10.1126/science.1244693

Despite this forest cover loss. total land plant biomass has been strongly increasing over the past 50 years, mostly due to CO2 fertilization of plants. The increase is about 0.4% per year (3.1 Pg) and offsets around 30% of human CO2 emissions.

FWIW, natural regen is the major cause of new tree growth,  not intentional planting, as your question shpposes
