Our current research addresses important environmental issues such as the impacts of global changes on rare plant populations and their biotic interactions, and conservation of heavily exploited plant species.

Our research areas include field-based work Florida, as well as research about plant conservation across the globe. Our international research has focused on the conservation of heavily exploited plant species which are consumed as traditional medicine.

Research Areas

Below you can read more about each of the above-mentioned research areas.

  • Field Based Research

    Our field based research is currently primarily located in Florida, on the ecology and restoration of threatened plants in swamp forests (epiphytic orchids and bromeliads), as well as the pine rocklands. These research projects have enabled us to engage and offer management consultation to various endangered species management agencies such as the US Fish and Wildlife Service, the Everglades National Park, the Florida Wildlife Conservation Commission and the Florida State Parks.

  • International Research

    Over-exploitation is among the greatest threats to species' survival. The deeply entrenched belief that wild plants are superior as Traditional Chinese Medicine (TCM) sources makes conventional interventions (e.g. replacing wild sourced products with cultivated) to reduce demand for wild harvested material ineffective. The conservation issue outlined above applies to Chinese medicinal orchids on which our research has been focused for a few years. It also applies to American ginseng (Panax quinquefolius), a well-known medicinal herb native to the deciduous forests in the Eastern United States.

Projects

  1. Assessing the impact of hurricane Irma and recovery trajectory of epiphytic communities in coastal buttonwood and mangrove forests in the Everglades National Park
  2. Orchid conservation in Cuba and Florida
  3. Conservation of illegally traded wildlife in South China
  4. How can we have our cake and eat it too – exploring effective promotion of semi-wild production of overexploited TM plants as a conservation measure
  5. RCN-UBE Incubator-Incorporating a short but intensive botanical experience into formal college courses to alleviate plant blindness among undergraduate STEM students
