That is great. In about 100 years you might have some timber that is worth something.
FYI, in 1880 New Hampshire was 80% cleared of all forests due to farming being the main industry. By 1980 NH was just the opposite. It is now over 80% forested. All the smart farmers moved to Indiana, Ohio, Iowa where they can grow things other than pine trees and rocks. The White Mountain National Forest was heavily cut for timber after the Civil War. Now those logging railroads and roads are hiking trails.
Maine is the most forested state by percentage in the country. Followed by NH & VT. All that timber that was cut in the 1800s all grew back by themselves from seed. Very little of it was actually planted.
Logging in the Adirondacks - videos like this I always find interesting. Really enjoy the tales of lore in the early logging industry.

The four year old ones are about 5 feet tall from 18” seedlings. If I outlive my wife, I might be buried amongst them. Who said I might not get any benefit from them? I figure 75 years and someone will have a valuable stand of timber. Are you aware the ash borer and the damage caused? In a matter of 15 years white ash went from commonplace to “functionally extinct”. It was an ecological catastrophe around here.
