Remaining wetlands = 800 × (1 - 0.12)^3 = 800 × (0.88)^3 = 800 × 0.681472 = <<800*0.681472=545.1776>>545.1776

Understanding Wetland Conservation: Calculating Remaining Vital Ecosystems Wetlands are among nature’s most valuable resources, providing critical ecological services like water purification, flood control, and carbon storage. But many wetlands face threats from development, pollution, and climate change. One powerful way to assess the impact of gradual wetland loss is through exponential decay models — particularly in conservation planning and environmental impact assessments. Recently, an analysis revealed that after a 12% annual reduction over three years, approximately 545.18 square kilometers of wetlands remain, calculated using the formula:
Remaining wetlands = 800 × (1 - 0.12)^3 = 800 × (0.88)^3
Breaking it down:
- Starting area: 800 km²
- Annual decline rate: 12% (so 0.88 of the previous year’s remaining wetlands survive)
- After 3 years: 800 × (0.88)³ = 800 × 0.681472 = 545.18 km² This model illustrates exponential decay — a concise way to represent how wetland degradation accelerates over time, especially in regions affected by urban expansion or agricultural conversion. Conservationists use such metrics to estimate how much habitat remains and to advocate for protective measures.
