“…presented a high vegetative development and productivity of dry matter, causing the suppression of styling (Stylosanthes capitata Vogel and Stylosanthes macrocephala M. B. Ferreira & Sousa Costa) in the consortium (FAVARE et al, 2018). Grasses are C4 plants adapted to full sun that occupy open areas, which can reduce the diversity of herbaceous (RIBEIRO et al, 2005) and woody species from natural regeneration and they can also increase the vulnerability of those areas to fire (CABIN et al, 2002;CORTINES;VALCARCEL, 2009;MOORE et al, 2011;FLORY et al, 2015;MANTOANI;TOREZAN, 2016). Areas infested by grasses have less resilient biotic components of the ecosystem and tend to inertial degradation, by ruderal herbaceous species, with intense cycles of plant growth and senescence, producing a highly flammable dry biomass in hot and dry periods, which inhibits the growth of woody species, whereas in the forest environment there is a natural tendency towards restoration (CORDELL et al, 2004;CORTINES;VAL-CARCEL, 2009;MOORE et al, 2011).…”

“…In Brazil, approximately 200 genera and more than 1,350 species of Poaceae have been described (LONDE;SILVA, 2014). Infestation of non-native forage grasses, mainly of the genus Urochloa is one of the most important biological barriers for the restoration in tropical forests areas (GARCÍA-ORTH; MARTÍNEZ-RAMOS, 2011;MANTOANI;TOREZAN, 2016). Urochloa decumbens (Stapf) R. D. Webster is an exotic grass that has adapted to the tropical environment throughout Latin America as it is quite tolerant to high levels of aluminum prevalent in acidic soils (SEIFFERT, 1980).…”

Invasive forage grasses, especially the Urochloa genus, impact reforestation worldwide. The aim of this study was to evaluate management influence on phytosociology of the herbaceous layer, defined as the layer of herbs, sub-shrubs, shrubs and vines, in two agroforestry systems (AFS) (Simple and Biodiverse) in succession to a reforestation of guanandi (Calophyllum brasiliense), compared to monoculture of this specie taken as control. The experiment was conducted in Pindamonhanga (SP), Brazil, from 2011 to 2014, in a randomized block design with eight replications and 144.0 m² plots. In Simple SAF area, food crops were grown alongside C. brasiliense rows: sweet cassava (Manihot esculenta) in rotation with arrowroot (Maranta arundinacea), pigeon pea (Cajanus cajan), banana shrub (Musa sp.), and juçara palm (Euterpe edulis). In Biodiverse AFS, fourteen native tree species were also planted alongside the food crops. Altogether 41 non-stratified species, 38 genera and 24 botanical families were identified; the most abundant families were: Asteraceae, Poaceae e Cyperaceae. The similarity between the areas diverged after three years of management, with the predominance of Commelina benghalensis and M. arundinacea in the AFS areas and Urochloa decumbens in the monocultive, mainly, due to the shadow gradient established for the three systems.

Understanding the influence of gaps in promoting canopy recruitment will help to maintain structural stability and achieve continuous forest cover. We established three control plots and experimental plots with three replications each (gap sizes L-I, L-II, L-III, and L-IV) in a Chinese pine (Pinus tabulaeformis Carr.) plantation to test the short-term effects of gap size on the age distribution, density and growth, and annual height and ground diameter growth for regeneration established before (REBG) and after (REAG) gap creation. Age distribution exhibited an approximately normal distribution, with the numbers of REBG and REAG decreasing and increasing, respectively, as the age increased. Although there was no difference in density among gap size classes, regeneration growth positively responded to gap size, with maximum values observed in class L-III. Annual average height growth after (AAH-A) gap creation was significantly greater than that before (AAH-B) gap creation for REBG among gap sizes, suggesting that gaps promote the rapid growth of regeneration. However, the responses of height and ground diameter growth in REBG to gap size were not immediate and exhibited a response delay of 2–4 years. Similarly, for the height and ground diameter growth of REAG, significant differences were first observed within years 2–4 after germination in the same growing season for all gap size classes.

“…They are aggressive and resistant species, dispersing easily, significantly interfering with infested crops. Without control, they can replace native species and, with the soil covered, it is very difficult to grow new trees (Silva, 1969;Ammondt & Litton, 2012;Dias et al, 2016;Mantoani et al, 2016).…”

Efficiency of Cardboard Crowning on the Suppression of Invasive Alien Grasses

et al. 2021

Invasive exotic grasses are among the biggest obstacles to the success of reforestation projects. The aim of this study was to evaluate the efficiency of the crowning with cardboard in suppressing the grasses Urochloa humidicola and Megathyrsus maximus aiming its use in reforestation areas. A field experiment was installed in a completely randomized design with two treatments consisted of crowning with cardboard and without crowning (control). The crowning with cardboard caused a progressive reduction of the biomass and was effective in causing senescence of both grasses in 80% or more of the crowning area between 20 and 50 days after the crowning (F test; p<0,05). These results demonstrate the effectiveness and potential of using the crowning with cardboard to control alien grass species in reforestation areas. This method brings as an innovation the possibility of placing cardboard directly on the grass after mowing, allowing greater simplicity and lower operating cost.
