My little corner of forest at my Parents' house has seen so many changes over the past 25 years.
Massive undergrowth of briars, controlled by preteens beating it back and clearing it out to make a "fort". Followed by covering by grapevines after the children grew, and then collapse of the shallow canopy. Deer destroying the lower grapevines followed by slow encroachment of surrounding trees. New rapid tree growth.
And now undergrowth is mostly limited. Trees are mostly taller. Deer and animal paths have altered through the years. A new community trail sits above on the hillside. Parts of the fort remain. I'm sure I altered the ground compaction & top soil personally. And I took over a spring-bed anyway.
It's neat in a quiet way.
