Janet Franklin's research is focused on in the dynamics of terrestrial (land) plant communities at the landscape scale. Her work addresses the impacts of human-caused landscape change on the environment. Human land use — agriculture and urbanization — and other large-scale human impacts such as global warming, and the introduction of exotic species, often interact with natural disturbance regimes such as fire, flooding and hurricanes, to shape plant community dynamics (succession). How resilient are ecological communities to these impacts? Terrestrial plant communities are important elements of regional biodiversity and provide essential habitat for more charismatic animal and rare plant species.

Janet and her students are currently working on: a) methods for predicting species distributions from environmental variables to study the impacts of climate change and land use change on biodiversity; b) exploring the impacts of anthropogenically altered fire regimes and land use change on flora and fauna in Mediterranean-Type Ecosystems in southern California and elsewhere using spatially explicit landscape simulation models and long-term datasets; and, c) understanding the long term impacts of human and natural disturbance on tropical forest island ecosystems in the Pacific and Caribbean. They use many research tools including field surveys, statistical modelling, computer simulation, remote sensing, spatial analysis and geographic information systems.

In 2014 Dr. Franklin was elected to the National Academy of Sciences. She has published more than 120 refereed papers in a wide variety of scholarly journals. Her research has been supported by the National Science Foundation, NASA and the National Geographic Society. She has also worked closely with the U.S. Forest Service and U.S. Geological Survey.
