Received 14 November 2007; revised 14 May 2008; accepted 3 June 2007; published 9 September 2008. [1] Afforestation of natural grasslands with fast-growing pine and eucalyptus species is increasing globally, but little is known about its effect on ecosystems and watersheds and, ultimately, the quality of water resources. To investigate the biogeochemical and hydrological consequences of this land use change, we sampled stream water in paired watersheds in Uruguay and Argentina. In watersheds… Expand

Figures and Tables from this paper

Soil C and N changes with afforestation of grasslands across gradients of precipitation and plantation age.
TLDR
The results suggest that the value of afforestation as a carbon sequestration tool should be considered in the context of precipitation and age of the forest stand, and that longer intervals between harvests for plantations could improve SOC storage, ameliorating the negative trends found in humid sites. Expand
Pine afforestation changes more strongly community structure than ecosystem functioning in grassland mountain streams
Abstract In the past decades, afforestation of grassland landscapes has gained importance both as an economic activity and a mechanism to mitigate anthropogenic carbon emissions. This study evaluatesExpand
Stream macroinvertebrate communities change with grassland afforestation in central Argentina
Abstract Lotic ecosystems are highly affected by land use changes such as afforestation of natural areas for management or commercial purposes. The aim of this study was to analyze the effect of pineExpand
Grassland afforestation impact on primary productivity: a remote sensing approach
Question: How is the magnitude and seasonality of carbon uptake affected by the replacement of native grasslands by eucalyptus plantations? Location: R�io de la Plata Grasslands in Argentina andExpand
A global meta-analysis of soil exchangeable cations, pH, carbon, and nitrogen with afforestation.
TLDR
It is suggested that proper site preparation and sustainable harvest practices, such as avoiding the removal or burning of harvest residue, could minimize the impact of afforestation on soils, and slow soil compaction, erosion, and organic matter loss, maintaining soil fertility to the greatest extent possible. Expand
Are soils beneath coniferous tree stands more acidic than soils beneath deciduous tree stands?
TLDR
Although limited to the top 15-cm of soil, the similarity in soil acidity between stands suggests that conifer growth may not be a substantial source of acidity to the Mulberry River. Expand
Hydrology and water quality of the headwaters of the River Severn: Stream acidity recovery and interactions with plantation forestry under an improving pollution climate.
TLDR
New information is presented on the hydrology and water quality of the eroding peatland headwaters of the River Severn in mid-Wales and the impact of plantation conifer forestry further down the catchment, indicating a reduction in stream acidification. Expand
Does grazing change algal communities from grassland and pine afforested streams?: A laboratory approach
Abstract Drastic changes in the composition and physiognomy of riparian vegetation, such as the conversion of grassland to forest, are expected to alter interactions among light availability, primaryExpand
Nutrient leaching and deep drainage under Eucalyptus plantations managed in short rotations after afforestation of an African savanna: Two 7-year time series
African savannas developed an efficient strategy of nutrient uptake and control of nitrification making it possible to avoid large losses of nutrient by drainage. The conversion of native savannaExpand
Eucalyptus short-rotation management effects on nutrient and sediments in subtropical streams

TLDR
A revised stream restoration plan for the Allegheny Plateau is proposed that includes restoring stream ecosystems as connected networks rather than isolated reaches and recognizes that full recovery of acidified watersheds may not be possible. Expand
