“…In other words, as light availability increased so did germination, survival and growth, which in turn, increased the reproductive success of the species. Canopy shade provided an effective barrier against invasion of L. camara (Duggin and Gentle, 1998), contrary to what was observed for C. excavata. Myers et al (2005) studied the behaviour of Alliaria petiolata (M. Bieb) Cavara and Grande, an invasive species in the United States, under several light conditions and observed that invasion of this species occurs at low and high light availability.…”

“…In other areas, such as Hawaii, this species is very invasive in disturbed areas causing serious problems (Space and Imada, 2004). While studying the effect of disturbance intensity on Lantana camara L. invasion, Duggin and Gentle (1998) observed that seed germination, survival and initial seedling growth were significantly and positively correlated with disturbance intensity. In other words, as light availability increased so did germination, survival and growth, which in turn, increased the reproductive success of the species.…”

The aims of this study were to evaluate the effects of light and temperature on seed germination and the effect of light on seedling emergence of Clausena excavata, an invasive exotic species. Seeds were incubated at constant temperatures (10 to 40 ºC), under continuous white light and darkness. Seedling emergence was evaluated under full sun and canopy shade. There was no significant difference between seeds germinated in the presence or absence of light at temperatures between 20 and 35 ºC. Seeds maintained at 20 ºC germinated more slowly than other temperatures. Independent of temperature, seed germination was much more synchronised under white light than under darkness. In the field, emergence occurred in both environments, but a greater percentage was observed under full sun. Seedling emergence occurred at the same rate and synchronisation index under both conditions. C. excavata has a high invader potential in open areas and shaded environments.

“…Both the above species are well known to be serious invaders that have shown to reduce richness and abundance of native species. Lantana camara is reported to limit recruitment of native species and alter ecosystem structure and function especially in the disturbed habitats when the cover is >75% (Gentle & Duggin, 1997;Duggin & Gentle, 1998;Sharma et al, 2005;Kohli et al, 2006;Gooden et al, 2009). Disturbances to forests such as canopy removal and gap formation have shown to increase the capacity of Lantana camara to suppress native species via greater resource acquisition and space utilization (Grice, 2004;Totland et al, 2005).…”

Abstract:The present study describes the current spread of plant invaders and management efforts at Mihintale, Sri Lanka's first recorded Wildlife Sanctuary. Among the five land use zones identified, roadside (RS), village (VA) and reservoir associated (RA) zones were subjected to a detailed analysis of diversity and abundance of Invasive Alien Plants (IAP) using stratified random sampling plots of 20 m x 20 m (n=09). Encroachment of IAP into the forested (FO) zone was studied using three 50 m transects established from edge to interior of the forest. The above ground diversity of IAP was assessed via Margalef's, Shannon -Weiner, Shannon evenness, abundance and important value indices. Aquatic IAP were also identified. Below ground diversity of IAP was estimated by enumerating soil seed banks via seedling establishment method. A questionnaire (n=60) was used to assertain the invasion history, awareness on IAP, their interference on human activities, uses and control measures adopted by the villagers. Nearly half of the IAP reported for Sri Lanka were present in the Mihintale Sanctuary. Richness of IAP was high in RA but the abundance was high at RS zone. Lantana camara and Chromolaena odorata had the highest spread, extending even >25 m into the forests. Salvinia was the most abundant aquatic IAP. Top soil layer contained the highest number of germinable IAP seeds. The villagers were well aware of the impacts of IAP and indicated their attempts and potential in IAP management. The study revealed that spread of IAP at the Mihintale Sanctuary currently lies at a manageable level. Better awareness among villagers on "do's and dont's with IAP" would assist in opening up more opportunities for community participation in effective IAP management.

“…Light has long been recognized as an important plant resource (Maximov, 1929;Blankenship, 2002) that may interact with other plant resources to affect plant performance (Cole, 2003). The increase in light availability increases the overall performance of lantana particularly the growth rate (Duggin and Gentle, 1998). Moreover, Chandrashekar and Swamy (2002) also reported that light availability in relatively less canopy enhance the growth of individual lantana.…”

Abstract. Invasion of lantana (Lantana camara L.) in dry deciduous forest is capable of causing changes in micro sites (soil properties and species composition) in which they invade. As lantana is most conspicuous invader in the Vindhyan dry deciduous forests of India. We analyzed the effect of this invasive species on the composition of herbaceous layer and on soil properties. Habitats with different level of canopy cover were analyzed. And the canopy cover was significantly related to the lantana cover. Results indicate that different levels of lantana cover affect soil properties and herbaceous species composition. We found as the lantana cover increases some of the species get locally extinct and some are favored by lantana invasion. Principal Component Analysis (PCA) ordination indicated that the quadrates with nil and differently covered lantana were unique with herb species composition, especially the sites with no lantana cover had native species which were not present in site with differently covered lantana. The distinctness of herb species composition is indicative of marked spatial dynamics with regard to nil and differently covered lantana. Concentration of organic carbon (OC) and total nitrogen (TN) were significantly higher in habitats having large lantana cover. Thus we may conclude that lantana modifies the spatial pattern of herbaceous plant species and the nutrient levels of soil.
