We have been planting many different trees species in the same area for over 14 years. So have real proof of tree growth for the zones of our carbon credit project. This allowed us to collect ground truth data from trees planted 5, 10 and 14 years ago.
We performed a forest inventory with our technology - measured 1,500+ trees to establish growth rates of species that will be planted in our project.
Assumptions:
Used Tanzanian derived allometric equations.
Trees from the dataset that were larger than the median were excluded for conservativeness
A 30% allometric uncertainty rate was also applied as a discount to the forecast.
