Stage Project from the start

“La Nueva Esperanza” (LNE) establishment in the vicinity of the town of Paso de los Mellizos (Río Negro) El Viraró (EV) establishment, close to the town of Los Cuadrados (Tacuarembó) We selected the most relevant geological formations (as potential aquifers): Asencio, Guichón and Salto (Coast) and Tacuarembó.

Examining the effect of eucalyptus forest plantations on the water balance at a local and regional level, as well as the quality of the surface water Look for correlations between variations in the level of groundwater deposits, rainfall and Eucalyptus forest plantations Evaluate the fluctuations in the water level of shallow aquifers with different proximity to Eucalyptus forest plantations through unused artesian wells. Evaluate variations over time in the chemical/physical and biological properties in water basin courses in the area of influence of the Eucalyptus forest plantations Examine the quality of the water in facilities where there are wells for human supply and classify this according to fitness for use Establish a base level for water quality prior to the installation of the nursery and monitor the long-term evolution

LNE: 2007-2010 Calibration 2011 Start of Monitoring EV: 2011-2014 Start of Calibration

Long-term (20 years)

Study in paired basins

2010 start of monitoring at the 3 plots along the coast. 2013 monitoring started on the Tacuarembó plot.

Hydrogeological Monitoring Plots

Medium-term (3-5 years)

No. of wells: 14 around the town of Grecco,

Started in 2008 with the wells of Soriano, with other locations added over time.

Monitoring of the level of artesian wells

Long-term (10 years)

7 around Paso de los Mellizos, 5 in Pueblo Paso de la Cruz and 5 in Soriano

Order 3 Basins (A.E Strahler classification) A° Quebracho (Paysandú) A° Sarandí (Soriano) A° Coladeras (Río Negro) A° Pablo Páez (Cerro Largo) A° Potrero (Florida)

2012 start of proceedings in the first 3 basins. The other 2 basins were included in 2013

Quality monitoring of surface water.

Long-term (10 years)

Monitoring of water quality and its suitability for different uses

All wells in sites under management by UPM-FO

2010 Systematic start-up.

Annual

6 underground water wells in the vicinity of the nursery (residents) and 2 sampling sites in Arroyo Santana 2 monitoring wells on the Nursery plot.

2011 Characterisation and definition of the base level: 2011 Start of monitoring at A° Santana. 2012 start of monitoring in phreatimeter wells.

Monitoring of water in the area of influence of the Santana Nursery

Medium and long-term (5 to 10 years)

ENVIRONMENTAL IMPACT

RELATIVE FREQUENCY OF DEVIATIONS DETECTED

The environmental impact derived from forestry operations in general are evaluated through operational monito- ring carried out by the managers or supervisors of these activities, during or after their performance. The following graph shows the frequency of deviations in internal monitoring in accordance with the non-compliance aspect (quality, legal/ administrative, environmental, etc.) Environmental accidents are reported by the supervisors and the correspon- ding mitigation measures must be taken. Other potential measurable impacts in the medium or long-term continue to be assessed: for example, the impact of harvesting techniques on the conser- vation of the physical and chemical characteristics of the soil and water quality in the harvest areas.
