Jacquemontia reclinata

A low (usually) growing vine found on the lee side of coastal sand dunes with white, star-shaped flowers (Small 1934, Martin 1994, Garvue 1999). The habitat for this plant is very rare and threatened by coastal development and rise in seas levels.

Distribution & Occurrence

Top

State Range

Florida

Habitat

A variety of habitats associated with coastal barrier islands, including sand dunes, tropical maritime hammock, & coastal strand in disturbed or natural areas (Robertson 1971, Ward 1979, Avery 1980, USFWS 1996(a), Fisher 2000, Coile 2000).

Associated species include: sea grape and other shrubs and dwarfed trees. Usually occurs with more or less weedy plants, occasionally with sea oats (USFWS, 1994)

Distribution

Historically, there is some confusion as to whether J. reclinata is native to the Bahamas and the West Indies or whether it is a Florida endemic (Robertson 1971, USFWS 1996(a)). Currently, it only occurs in a few sites along the east coast of Florida from Martin County south to Dade County. The entire range, from Jupiter Island to Key Biscayne is only 85 miles.

Number Left

733 individuals in all ten populations, although most are in just 2 sites (USFWS 2001).

Ecological Relationships

This species thrives after disturbance, such as a hurricane or fire. The plants spread over exposed microsites on dune faces from rootstock that is centered under a shading shrub. Plants flower, set fruit and disperse prolifically, but few seedlings or young plants are found. Interestingly, 70%+ of seeds germinate in the greenhouse.
Germination rates appear to be higher in organic soils and shade, and seeds are generally short-lived in soil. Transplants grow readily in the field. (USFWS 1996)

Threats

Threats include:
� Parasitic vines
� Public recreation
� Hurricanes
� Beach erosion
� Manicured landscaping
� Exotic species (Australian pine, Brazilian pepper, carrotwood, grasses) (USFWS 1996(a), 1996(b), E. Pinto, pers. comm.; Lane et al., 2001)
� Urbanization (Austin, 1979, Robertson 1971, USFWS 2001)
� Habitat fragmentation

Current Research Summary

Fairchild Tropical Garden is conducting extensive ecological studies on J. reclinata including: pollination ecology, seedling requirements, propagation, genetics, and habitat characteristics (Lippencott 1990). In the near future, studies on restoration will be conducted. Habitat Specialists, Inc. are also conducting studies on restoration. Florida State Department of Environmental Protection has also worked on reintroduction of this species.

Current Management Summary

Invasive species removal.

Research Management Needs

Research and management needs include investigating and implementing exotic species removal and response to fire.

Ex Situ Needs

None.
