Global analysis shows that fires have positive impacts on water provision and negative impacts on water quality, climate regulation, and erosion control. There is no overall significant effect on food provision and soil fertility. However, data is limited and future research should focus on underrepresented regions and biomes.
Fire is a primary disturbance in the world's forested ecosystems and its impacts are projected to increase in many regions due to global climate change. Fire impacts have been studied for decades, but integrative assessments of its effects on multiple ecosystem services (ES) across scales are rare. We conducted a global analysis of persistent (>1 year) fire effects on eight ES reported over the past 30 years, evaluating qualitative and quantitative information from 207 peer-reviewed studies. Significant effects were predominantly positive for water provision and negative for water quality, climate regulation, and erosion control; for food provision and soil fertility, no overall significant effects emerged; and for recreation or pollination, data were insufficient. These effects were generally short-lived (1-2 years) and were more common after wildfires than after prescribed burns. However, available data were primarily derived from only a few countries/biomes and extended only over short time periods, highlighting the need for future research focusing on underrepresented regions and biomes, more extensive timeframes, and multiple ES.
