@MisterRogersSnapped I started tree planting when I was 15. My first year resulted in 151 native tree plantings, in total I've planted 4,700 trees as of today.
Gradually I've been building an operation to germinate and plant trees at 0 cost. I've started with the Largest Flowering Tree; Eucalyptus Regnans this year after acquiring a steady supply of legal seeds at very low cost from a diverse population of parent trees.
Eucalyptus Regnans grows to 90 meters/300 feet at a rate of 1-3 meters a year. Roughly 2 meters a year for the first 20 years of its life.
My goal is to plant 500+ a year for the rest of my life in Australia, sinking approximately 80 tonnes of carbon per tree I plant. Plus more in soil bacteria and the ecosystems living in the tree's canopy.
If I can manage 500 of them next year, in addition to other native plants, I'll be trying for 1,000 the year after.
