In response to warming winters, mangroves have been expanding and displacing salt marshes at varying degrees of severity in parts of north Florida, Louisiana, and Texas. A paper published in Global Change Biology, led by Michael Osland (USGS) with contributions from 21 coauthors including Mike Allen (NCBS); and Joe Marchionno (UF ESSIE PhD student), reviews the current understanding of impacts of mangrove range expansion on wetland ecosystem services. The authors identify knowledge gaps and research needs related to ecological and societal concerns over mangrove range expansion. While mangrove range expansion can produce beneficial changes to wetland ecosystem services (e.g., improved coastal fish and wildlife habitat), it also can produce detrimental changes to other services (e.g., loss of coastal views, impacts to property values). These service trade-offs are an important consideration for coastal managers due to the scale of their impacts. The paper summarizes the important implications of mangrove expansions given climate change.
