A recent study reviewing 53 scientific papers has found that efforts to protect biodiversity in forests used for timber production can result in both financial costs and benefits. Researchers from Wageningen University & Research in the Netherlands and the University of Freiburg in Germany analyzed 814 scenarios that included various conservation strategies, such as delaying tree harvesting, preserving habitat trees and deadwood, and increasing the variety of tree species. Their findings, published in the journal Current Forestry Reports, reveal that in 41 of the studies, biodiversity conservation measures had a negative financial impact compared to standard forest management practices. However, in 12 of the studies, the financial effects were positive. When only direct costs were considered, the average profitability of biodiversity measures was about 5% lower than traditional management methods. However, when the study accounted for indirect financial benefits—such as the potential for more diverse forests to act as a form of insurance against climate change impacts, reduced operational costs from less intensive management, higher-quality timber, and additional income from payments for ecosystem services—the average profitability was nearly 20% higher than under conventional practices. The study’s lead author, Lorenz Schimetka, explains that while biodiversity can help forests better withstand climate change, many studies have struggled to quantify these benefits in monetary terms. This difficulty has led to a bias in some research, making biodiversity measures appear less profitable than they might actually be. The profitability of these measures also varies depending on the specific conservation strategy, the type of forest, and assumptions about factors like timber prices, climate change, and future environmental disruptions. The researchers emphasize that while financial profitability is an important consideration in forest management, it is not the only one. Forests provide a range of societal benefits, including clean air, water, and habitat for wildlife, and they hold intrinsic value as complex ecosystems. Study leader Professor Georg Winkel notes that while environmental and economic goals can align in forest management, decisions should be based on a broader set of considerations than just financial gain.
