Since its inception as a public garden, the Morris Arboretum has served as a center for botanical research. The original research staff included Dr. Rodney True, Dr. Edgar Wherry, and Dr. John Fogg. These and other scientists at the Arboretum have had considerable impact on the understanding of the flora of Pennsylvania and beyond.
Today, The PA Flora Project's botanical research efforts focus on the occurrence of the native and naturalized plants that inhabit Pennsylvania. We recognize the importance of understanding the dynamic nature of the flora and seek to gain insights into these changes through work in the field, laboratory, and at the computer. We maintain the Pennsylvania Flora Database, a database of more than 400,000 plant records, to help store and disseminate the data we obtain in our research.
We also are working to extend the scope of our research efforts. Future directions include expanded work in plant systematics, ecology, and evolutionary studies.
My research interests are in the flora of Pennsylvania and in GIS mapping of plant distribution.
My research interests are focused on the floristics of Pennsylvania. I want to document the natural vegetation of the state and better understand historical and contemporary influences that have shaped the patterns of plant distribution we see today.
"My research is focused on the systematics and evolution of plants. I enjoy studying plants at many levels, from ecosystems to species to organs to genes. I am particularly interested in the floras of Pennsylvania and Madagascar, the digitization and dissemination of herbarium/floristics data, and the evolution of separate sexes in flowering plants."
The Arboretum is open as usual. Click here for hours.
