## How to Plan Reforestation

Reforestation restores forest cover to sequester carbon and rebuild ecosystems.

### Formula

**Trees Needed = Area * Planting Density**

**Cost = Trees * Cost per Tree**

### Planting Density

- Dense restoration: 1,000-1,600 trees/ha
- Moderate: 600-1,000 trees/ha
- Agroforestry: 200-400 trees/ha

A new forest can sequester 5-10 metric tons CO2/ha/year once established.

Exemple Résolu

Reforest 50 hectares at 1,100 trees/ha, $2.50/tree, over 20 years.

  1. Total trees: 50 * 1,100 = 55,000 trees
  2. Cost: 55,000 * $2.50 = $137,500
  3. Annual sequestration: 50 * 5 = 250 metric tons CO2/year
  4. Total carbon: 250 * 20 = 5,000 metric tons CO2
  5. Cost per ton: $137,500 / 5,000 = $27.50/ton
