• Direct Non-Consumptive Use Value:
• Environmental economic valuation of forest ecosystem services:
• Direct Non-Consumptive Use: Value derived from experiencing forest amenities without physically harvesting or consuming tangible biomass—specifically Education, scientific research, and ecotourism/bird watching.
• Soil conservation and carbon storage are indirect use values. (Correct answer: Option 1)
