Government is the primary financer of conservation services, but conservation financing in government is rarely studied. This study makes two contributions to understanding conservation financing in government. First, it develops a framework to classify and analyse conservation funding. Applying this framework to the data from Florida county governments, this study finds that conservation funding has become more stable and secure. More resources are used for large and long-term capital projects that benefit not only the current generation but also future generations, which reflects the ultimate goal of conservation. Second, this research offers an explanation about why some governments spend more on conservation than others. The results suggest that conservation funding in government is the result of combined forces in environmental pressure of economic activities and budgetary politics. The paper concludes that government should develop a structured conservation funding strategy that includes close monitoring of environmental pressure and proper political and institutional responses to the pressure.
