Overview

Cost-effectiveness analysis reveals temporary conservation reduces breeding habitat protection costs 14-fold for grassland birds, suggesting dynamic strategies effectively supplement fixed reserves.

Key Points

To evaluate whether temporarily conserved areas provide a more cost-effective alternative to permanent protected areas for safeguarding migratory grassland bird breeding habitat.
Identified critical zones containing 30% of Bobolink and Eastern Meadowlark populations across 17% of mapped suitable habitat in southern Ontario, Canada.
Modeled the cost-effectiveness of permanent land acquisition against temporary conservation agreements that financially compensate farmers for delaying the first hay harvest.
Evaluated 10-year present values across three social discount rate scenarios (-3%, 0%, and +3%).
Present value estimates for a 10-year temporary conservation term were 14 times cheaper than permanent protected areas under the baseline 0% discount rate.
Temporary conservation agreements delivered the highest relative cost-effectiveness in the southernmost areas where land purchase prices were most expensive.
