Summary of Invasiveness
Top of pageT. grandiflora is a woody vine included in the Global Compendium of Weeds and it is listed as a very aggressive weed impacting tropical and subtropical ecosystems (Randall, 2012). This species has been repeatedly introduced as an ornamental plant in many countries around the world, but it has become a serious environmental problem when it has escaped from cultivated areas and rapidly colonized natural habitats (ISSG, 2012). The rapid colonization of new habitat by this vine is mainly due to its capability to reproduce sexually by seeds and vegetatively by cuttings, fragments of stems and roots (USDA-NRCS, 2012). Once established, T. grandiflora completely smothers native vegetation by killing host-trees, out-competing understory plants, and negatively affecting the germination and establishment of seedlings of native species (Starr et al., 2003). Currently, T. grandiflora is classified as a “noxious weed” in Australia (Queensland Department of Primary Industries and Fisheries, 2007), and as an invasive species in Central America, the West Indies, Africa, and numerous islands in the Pacific including Hawaii, Fiji, French Polynesia, Palau, and Samoa (see distribution table for details; Acevedo-Rodríguez and Strong, 2012; ISSG, 2012; PIER, 2012).

History of Introduction and Spread
Top of pageT. grandiflora was probably introduced as an ornamental in the Caribbean Region late in the nineteenth century. It appears in an 1892 herbarium collection made by A. Duss on Guadeloupe Island (Smithsonian Herbarium Collection). Later, Ignaz Urban in his book Symbolae Antillanae reported this species as “cultivated in gardens and escaped” for the islands of Cuba, Guadeloupe, Dominica, Martinique, and St. Vincent (Urban, 1901). T. grandiflora was also reported as commonly planted in gardens by N.L. Britton in Bermuda in 1918 (Britton, 1918) and in Puerto Rico and Virgin Islands in 1925 (Britton and Wilson, 1925). During the 1990s this species has been collected in Puerto Rico from naturalized individuals from widespread localities (Acevedo-Rodríguez, 2005). In Hawaii, T. grandiflora was first collected in 1937 on O'ahu and it is now spreading along hiking trails or margins of urban areas, at least on Kaua'i, O'ahu, Maui, and Hawaii (Wagner et al., 1999; Starr et al., 2003).
Risk of Introduction
Top of pageT. grandiflora has been intentionally planted as an ornamental and it has escaped from gardens and spread rapidly into natural forests, climbing into the canopy of mature trees and forming dense monoculture stands (Starr, 2003; ISSG, 2012). In addition, it has a natural great dispersal capability by seeds, fragments of stems and roots (PIER, 2012). In consequence, the probability of invasion of this species remains high.
Habitat
Top of pageT. grandiflora can be found growing in moist areas from sea level to middle elevations. It is especially common in disturbed areas, urban forests near human settlements, riparian forests, forest gaps, forest edges and along roadsides (ISGG, 2012; PIER, 2012). In Australia, this species has been reported growing in areas from sea level to 750 metres in riparian areas, rainforest margins, roadsides, disturbed sites and old gardens (Queensland Department of Primary Industries and Fisheries, 2007). In Hawaii, T. grandiflora grows in lowland moist areas, disturbed forests, and urban areas (Starr et al., 2003).

Biology and Ecology
Top of pageGenetics
The chromosome number estimated for T. grandiflora is 2n=28 (Daniel and Chuang, 1989).
Reproductive Biology
For species in the genus Thunbergia, flowers are bisexual, zygomorphic, axillary, usually solitary, with long pedicels and a pair of foliaceous bracts covering the lower portion of the corolla (Acevedo-Rodríguez, 2005). In the case of T. grandiflora, pollinators are unknown, but based on floral traits, this species could be considered entomophilous.
Physiology and Phenology
In Puerto Rico, T. grandiflora has been recorded flowering throughout the year and fruiting sporadically from May to July (Acevedo-Rodríguez, 2005). In Australia, it produces flowers and fruits throughout the year (Queensland Department of Primary Industries and Fisheries, 2007).
Environmental Requirements
T. grandiflora grows best on fertile soils with good drainage in areas with warm temperatures at low elevation (i.e., from sea level to about 750 metres; Queensland Department of Primary Industries and Fisheries, 2007). This species does not tolerate shaded conditions and climbs over trees and shrubs looking for sunny areas in the canopy of the forests.

Notes on Natural Enemies
Top of pageThunbergia species are susceptible to spider mites, whiteflies, and scale insects (Brickell and Zuk, 1997).
Means of Movement and Dispersal
Top of pageT. grandiflora reproduces sexually by seeds and vegetatively by stem fragments, tubers, and roots (Starr et al., 2003; ISSG, 2012; PIER, 2012). Seeds are catapulted several metres when ripe pods open and they can also be dispersed by rivers, streams and on waterways after rain storms (Queensland Department of Primary Industries and Fisheries, 2007). T. grandiflora also spreads by underground tubers and roots that easily re-spread producing new plants. Fragments of stems and roots may be dispersed to new locations by humans, livestock, vehicles, and/or floodwaters. Tubers and roots can also be spread by the movement of soil (Starr et al., 2003; BioNET-EAFRINET, 2011; ISSG, 2012; PIER, 2012).

Environmental Impact
Top of pageT. grandiflora has an extensive tuberous root system, which can weigh up to 70 kg and can damage river banks, paths, fences and building foundations (Motooka et al., 2003). This fast-growing vine forms dense colonies that engulf native vegetation, climbing high into forest canopies and shading-out vegetation in the understory of native forests. For example, in some areas in Australia this species can cover 100% of the vegetation (Queensland Department of Primary Industries and Fisheries, 2007). It also impacts negatively on the germination and establishment of seedlings of native plants and the weight of the stems can kill host- trees (BioNET-EAFRINET, 2011; ISSG, 2012). In Australia, T. grandiflora is a serious environmental problem. It is affecting agricultural lands and it is a serious danger to the survival of small remnants of the threatened lowland tropical rainforest in the areas of Queensland that have been fragmented by agricultural and urban development (Queensland Department of Primary Industries and Fisheries, 2007).

Uses
Top of pageT. grandiflora is an economically important species widely cultivated as an ornamental and as a hedge plant in tropical and subtropical regions (Starr et al., 2003). This species is still sold in nurseries and is commonly planted to cover fences and walls in gardens in warm climates. In addition, T. grandiflora is used as a medicinal plant in traditional medicine in Asia and Africa. In Tropical Africa (Tanzania and Uganda), it has been used as a source of green manure and for fuelwood (Bio-NET-EAFRINET, 2011).

Similarities to Other Species/Conditions
Top of pageT. laurifolia is very similar in appearance and habit to T. grandiflora. It has similar flowers; leaves are of similar size but with a different shape and texture, being oval and narrowing to a pointed tip (Queensland Department of Agriculture and Fisheries, 2007).
Prevention and Control
Top of pageDue to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
Physical/Mechanical Control
Small plants as well as small infestations should be removed manually. All plant segments and roots have to be removed in order to avoid re-sprouts. Large mature plants have extensive underground root systems, thus specialized machinery is necessary. In addition to mechanical control, the use of this species as an ornamental should be discouraged, especially in areas near natural forests (Queensland Department of Agriculture and Fisheries, 2007).
Chemical Control
Spraying or painting cut stumps with herbicides such as glyphosate is an effective control method (Bio-NET-EAFRINET, 2011). Imazapyr is very effective in killing thunbergia, and does not drastically affect surrounding vegetation (Queensland Department of Agriculture and Fisheries, 2007). Good application technique should result in few non-target plants being killed.
Control recommendations suggest that chemical control of T. grandiflora should include mechanical cutting followed by applications of herbicides such as glyphosate, triclopyr or 2.4-D to the cut stems. Follow-up treatments are recommended until control is completed (Motooka et al., 2003; Queensland Department of Agriculture and Fisheries, 2007).
