Linking local and formal knowledge to uncover the socioecological effects of an extreme event.

Extreme events are changing the structure and functioning of forests worldwide, and often times reducing abruptly their capacity to provide ecosystem services, especially to rural communities intimately linked to their environs. A historic cold wave in early February 2011 led to a severe frost across northwestern Mexico, with negative effects particularly at lowland areas where most economic activities take place. This frost caused widespread tree mortality in the tropical dry forest ecosystem especially in the municipality of Alamos in southern Sonora, Mexico. In this region, we conducted 20 semi-structured interviews at the Sabinito Sur community and performed field surveys on the surrounding frost-damaged forests to analyze the socioecological effects of the extreme frost. A 100% of interviewed people recall this frost because it damaged their orchards, native fruit trees and sources of firewood which are typically derived from nearby native vegetation, particularly secondary forests developing on abandoned agricultural or pasture lands that were once native forests. Both mature and secondary forests were damaged, but frost effects were more severe on the latter as suggested by density of frost-killed trees. The loss of woody plants forced local people to travel longer distances to obtain their goods. This information can be useful for developing strategies to speed forest recovery targeting beneficial species and for increasing the adaptive capacity of rural communities to novel future climates. Our study suggests that combining local and more formal scientific knowledge can help us better understand the short- and long-lasting socioecological effects of extreme events.
