“…In southern Brazil, Thomas (2017) showed that topsoil removal and herbicide application were effective in reducing cover of Urochloa decumbens from over 40% to less than 5% 1 year after treatment, but did not promote re-establishment of typical grassland species, even when combined with hay transfer. Establishment of an assemblage of competitive native species after eradication of invasive species is thought to be important to prevent reinvasion of restored sites (Cordero et al, 2016). Unfortunately, despite successful invasive plant control in small plots in short-term experiments, over the longer term at larger spatial scales, restorations remain prone to reinvasion (Sampaio et al, 2015).…”

Despite growing recognition of the conservation values of grassy biomes, our understanding of how to maintain and restore biodiverse tropical grasslands (including savannas and open‐canopy grassy woodlands) remains limited. To incorporate grasslands into large‐scale restoration efforts, we synthesised existing ecological knowledge of tropical grassland resilience and approaches to plant community restoration. Tropical grassland plant communities are resilient to, and often dependent on, the endogenous disturbances with which they evolved – frequent fires and native megafaunal herbivory. In stark contrast, tropical grasslands are extremely vulnerable to human‐caused exogenous disturbances, particularly those that alter soils and destroy belowground biomass (e.g. tillage agriculture, surface mining); tropical grassland restoration after severe soil disturbances is expensive and rarely achieves management targets. Where grasslands have been degraded by altered disturbance regimes (e.g. fire exclusion), exotic plant invasions, or afforestation, restoration efforts can recreate vegetation structure (i.e. historical tree density and herbaceous ground cover), but species‐diverse plant communities, including endemic species, are slow to recover. Complicating plant‐community restoration efforts, many tropical grassland species, particularly those that invest in underground storage organs, are difficult to propagate and re‐establish. To guide restoration decisions, we draw on the old‐growth grassland concept, the novel ecosystem concept, and theory regarding tree cover along resource gradients in savannas to propose a conceptual framework that classifies tropical grasslands into three broad ecosystem states. These states are: (1) old‐growth grasslands (i.e. ancient, biodiverse grassy ecosystems), where management should focus on the maintenance of disturbance regimes; (2) hybrid grasslands, where restoration should emphasise a return towards the old‐growth state; and (3) novel ecosystems, where the magnitude of environmental change (i.e. a shift to an alternative ecosystem state) or the socioecological context preclude a return to historical conditions.

“…As Johnson (2001) highlights, the expansion of established gorse bushes scrub into the areas of natural grasslands after fire. Cordero et al (2016), in the study of the structure of mosaics community of forests and fields in the region, observed that Ulex did not invade native forests. However, the species invaded planted forests and highly grazed fields.…”

“…of the plant species exotic, originating as ornamentals. Cordero et al (2016) studied the phytossociology of the shrub Ulex europaeus in a forest-grassland mosaic and found that this shrub it cover 10.1% of the total area studied. In a literature survey of alien herbaceous plants and shrubs, Rolim et al (2015) found that most species have geographical origin in Central Europe and predominantly reproduce by small seeds or fruits.…”

Exotic species are spreading in various parts of the planet and sometimes becoming biological invaders. A floristic survey was carried out to find exotic trees, shrubs, and climbers in different communities in Pelotas, Rio Grande do Sul, southern Brazil. The traversal method was used at 26 sites. The richness totaled 26 species in 22 genera and 17 families. There are 19 trees, 5 arborescents, 1 shrub, and 1 climber. Most of the exotic species are already naturalized in the study area. Between 1 and 10 individuals sporadically occur at each site. For species of characteristically invasive exotic plants were observed, including 3 trees (Pinus elliottii Engel, Pinus taeda L. Engelm., and Pittosporum undulatum Vent.) and 1 shrub (Ulex europaeus L.). A continuous monitoring of exotic flora is needed to eliminate or control invasive plant species and to avoid economic and ecological damage to ecosystems.

“…The 'Cambui' tree (Myrciaria tenella) belongs to the Myrtaceae family, originating from South America (Sessa et al, 2016), South (Belem et al 2016;Tonetti & Biondi, 2016;Cordero et al 2016) and Southeast states of Brazil, it can also be found in the Northeast of the country (Silva et al, 2012), as in areas of the 'Chapada Diamantina', Bahia State. It is mainly used as an ornamental plant and its wood is used for fence posts, tools and firewood (Lorenzi 2000).…”

Chemical characterization and antioxidant capacity of ‘Cambui’ (Myrciaria tenella) products

et al. 2019

Article AbstractVery little information is found about the 'Cambui' products and the fruit is almost unexplored by the Brazilian agriculture or extractive activities. The present study aimed to characterize the physicochemical composition and antioxidant capacity of the juice, jam and fermented beverage obtained from 'Cambuí' fruits aiming to add value to the fruit and generate alternatives to Brazilian extractive population. These products were elaborated in small scale of production. The 'Cambuí' juice was prepared using the method of steam distillation and the jam was obtained from the residue of the juice with addition of sugar and citric acid. The 'Cambuí' fermented beverage was elaborated using procedures of winemaking. For the evaluation of the products quality, chemical analysis and evaluation of the antioxidant capacity were performed.All products presented high concentrations of the studied variables, when comparing to grape wines, fruit jams and grape juices. The 'Cambui' products can be considered sources of antocyanins and other phenolic compounds, with high antioxidant potential. The use of 'Cambui' has potential for the development of juice, jam and fermented beverage, and these products can be an alternative to add value to fruit and generate income for populations that work with which income depend on extractive activities.
