• Red maple is one of the most widely geographically distributed tree species in eastern North America.
• Although a minor component of most presettlement forests, it has greatly expanded its range and influence in upland forests
• Loss of oaks and pines is perceived to be a consequence of this massive invasion.
Rationale
![Page 3: Landscape Ecology of a Native Invasive, Red Maple (Acer rubrum L.) School of Natural Resources & Environment McIntire-Stennis Cooperative Research October](https://reader035.vdocuments.us/reader035/viewer/2022062515/56649d245503460f949fa777/html5/thumbnails/3.jpg)
• The reasons for its widespread expansion are not clear and this expansion has been has termed a "paradox.”
• Also, red maple has been labeled a "super-generalist." However, based on research with its sister species in Japan, I hypothesize that our red maple is a "super-specialist" -- in wetland ecosystems.
• Thus, the widespread occurrence of wetlands throughout eastern North America has provided red maple access to adjacent uplands.
• Research to date has neglected the wetland ecosystem home of red maple as a fundamental reason for its expansion.

Objectives
• Develop a conceptual ecosystem-based model of red maple occurrence, expansion, and persistence in space and time.
• Determine the full range of wetland ecosystems currently occupied by red maple occurrence on moraine, ice-contact, and lake plain landforms in SE Michigan.
• Determine the change in composition of red maple and American elm over a 30-year period in three wetland ecosystems of SE Michigan.

Approach• Conduct a comprehensive literature review of the
presettlement occurrence of red maple in wetlands and uplands of eastern North America.
• Determine the full range of ecosystems occupied in moraine, ice-contact, and lake plain landforms in SE Michigan through transect and plot sampling.
• Determine change in red maple composition over time by re-sampling permanent sample plots in three wetland ecosystems established in 1974 in SE Michigan
