ABSTRACT.
This work studies the effects of forestation on forage mass and its chemical composition, as well as mean air temperature and their impact on beef cattle performance and grazing behaviour when compared to a natural grassland system. The systems comprised 100% natural grassland from the Campos biome (NG) and forested land (FL) 60% 6 y.o. Pinus taeda (500 trees per hectare) and 40% of natural grassland. We found that the crude protein composition of the pasture growing under the trees was higher, while mean air temperature was lower during the hot season. This changed the grazing pattern of the cattle, and was associated with higher average daily gain of the animals grazing in FL. We conclude that the introduction of trees in natural grasslands changed the environmental conditions, providing a better thermic and nutritive situation for growing grazing cattle that ultimately results in an increase in their productivity. © 2018, Springer Nature B.V. |

Abstract
Management of native weeds in natural grasslands is a challenging task. Often, recommendations are based on short?term studies of the response of weed cover and density to different control methods. However, perennial species well adapted to disturbances typically recover from commonly used control techniques. In this long?term study, we focused on a rosette native to the South American Campos : Eryngium horridum Malme (Apiaceae). This plant is strongly avoided by cattle due to its spiny leaves and tends to form dense patches, reducing the available grazing area. We aimed at understanding how key demographic processes, such as size?related plant survival and seedling establishment, are affected by different control treatments. For this, E. horridum cover, density and size structure were assessed over three years in response to mechanical, chemical and integrated (mechanical + chemical) control methods. In a field experiment, we used a weighted rim and a wiper applicator with 2,4?D + picloram for the mechanical and chemical control, respectively. Cover was reduced by control treatments (?control phase?), but this was not sustained in the long term (?recovery phase?). Regardless of the method used, control success was closely related to effects on population size structure. Mortality was high and rapid in large rosettes, which effectively led to a rapid and widespread cover reduction in all control treatments. However, only herbicide reduced rosette density delaying the recovery phase. Seedling density was low during the experimental period and scarcely affected by treatments. We conclude that cover reduction depends on removing all large rosettes, but recovery is related both to the size of the remaining pool of small rosettes and to the ability of buried rhizomes to resprout. Finally, we highlight the importance of finding a balance between productive goals and biodiversity conservation. In that context, integrated control successfully reduced cover, delayed recovery and minimised the amount of herbicide used. MenosAbstract
