Michael Johannes Osland, Ph.D.
Michael Osland is a Research Ecologist at the USGS Wetland and Aquatic Research Center in Lafayette, Louisiana.
In broad terms, his research examines the effects of global change on ecosystems and the implications for ecological conservation and restoration. Much of his research focuses on wetland ecosystems at the dynamic interface between land and ocean (mangrove forests, salt marshes).

Understanding Ecosystem Response and Infrastructure Vulnerability to Sea-Level Rise for Several National Parks and Preserves in the South Atlantic-Gulf Region
USGS Researchers at the Wetland and Aquatic Research Center and the St. Petersburg Coastal and Marine Science Center will provide valuable information to natural resource managers on how important coastal ecosystems in the National Park Service South Atlantic-Gulf Region may change over time. This information could assist with future-focused land management and stewardship.
Winter Climate Change and the Northward Range Expansion of Tropical Invasive Plants in the Southeastern United States
Using temperature, species occurrence, field-based freeze damage data, and regression analyses for 84 invasive species, researchers at WARC are quantifying the species-specific relationships between minimum temperature and plant presence.
The Response of Coastal Wetlands to Sea-level Rise: Understanding how Macroscale Drivers Influence Local Processes and Feedbacks
The purpose of this work is to advance our understanding of how coastal wetland responses to sea-level rise (SLR) within the conterminous United States are likely to vary as a function of local, regional, and macroscale drivers, including climate. Based on our interactions with managers and decision makers, as well as our knowledge of the current state of the science, we propose to: (a) conduct a...

Identification of Hydrologic Controls on Coastal Spartina patens Marshes and Optimal Hydrological Conditions for Sustainable Mottled Duck Habitat
Mottled ducks rely on the coastal marshes of the Texas Chenier Plain, which are considered among the most critically endangered habitats in the United States. USGS scientists are evaluating what might be contributing to the degradation of high-quality mottled duck habitat to better understand the causes of habitat loss and subsequently mitigate those losses.
Communicating Future Sea-Level Rise Scenarios for Gulf Coast National Wildlife Refuge and National Park Lands
Low-lying public lands along the northern Gulf of America coast are vulnerable to sea-level rise. Coastal planners and resource managers in the region have requested customized information that can be used to concisely communicate local sea-level rise scenarios and identify potential impacts to the missions of management agencies. In this project, researchers will work with partners to...
Identifying the Ecological and Management Implications of Mangrove Migration in the Northern Gulf of America
In the northern Gulf of America, mangrove forests have been expanding their northern range limits in parts of Texas, Louisiana, and north Florida since 1989. In response to warming winter temperatures, mangroves, which are dominant in warmer climates, are expected to continue migrating northward at the expense of salt marshes, which fare better in cooler climates. The ecological...
Mangroves vs. Salt Marshes: Mangrove Forest Range Expansion at the Expense of Salt Marshes
Winter climate change has the potential to have a large impact on coastal wetlands in the southeastern United States.
Incorporating Future Change into Current Conservation Planning: Evaluating Wetland Migration along the Gulf Coast under Alternative Sea-Level Rise and Urbanization Scenarios
More than half of contiguous U.S. coastal wetlands are located along the Gulf Coast. These highly-productive wetlands support many ecosystem goods and services and fish and wildlife habitat. Historically, coastal wetlands have adapted to sea-level changes via lateral and vertical movement on the landscape. As sea levels rise in the future, coastal wetlands will adapt and migrate landward into...
Mangrove Migration Network
At the poleward marsh-mangrove ecotone, mangrove abundance and coverage is winter temperature-sensitive in that it oscillates in response to the frequency, duration, and/or intensity of extreme winter temperatures. Future winter climate change is expected to facilitate poleward mangrove range expansion at the expense of salt marshes in Texas, Louisiana, and parts of Florida.
Macroclimatic Controls of Coastal Wetland Ecosystem Structure and Function
At the global-scale, macroclimatic drivers govern ecosystem structure and function in tidal saline wetlands (e.g., salt marshes, mangrove forests, salt flats). However, global reviews and models for these ecosystems typically do not directly include climatic drivers. The objective of this research is to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure and...
Enhancing the Capacity of Coastal Wetlands to Adapt to Sea-Level Rise and Coastal Development
Coastal wetlands provide a suite of valuable benefits to people and wildlife, including important habitat, improved water quality, reduced flooding impacts, and protected coastlines. However, in the 21st century accelerated sea-level rise and coastal development are expected to greatly alter coastal landscapes across the globe. The future of coastal wetlands is uncertain, challenging...
