SUMMARY OF ONGOING PROJECTS
ENVIRONMENTAL IMPACT
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.

Study in paired basins
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
“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)
LNE:
2007-2010 Calibration
2011 Start of Monitoring
EV: 2011-2014 Start of Calibration
Long-term
(20 years)
Hydrogeological
Monitoring Plots
Look for correlations between
variations in the level of groundwater
deposits, rainfall and
Eucalyptus
forest plantations
We selected the most relevant
geological formations (as potential
aquifers): Asencio, Guichón and
Salto (Coast) and Tacuarembó.
2010 start of monitoring at the 3 plots
along the coast.
2013 monitoring started on the
Tacuarembó plot.
Medium-term (3-5 years)
Monitoring of the level of
artesian wells
Evaluate the fluctuations in the
water level of shallow aquifers with
different proximity to
Eucalyptus
forest
plantations through unused artesian
wells.
No. of wells:
14 around the town of
Grecco,
7 around Paso de los Mellizos, 5
in Pueblo Paso de la Cruz and 5 in
Soriano
Started in 2008 with the wells of
Soriano, with other locations added
over time.
Long-term
(10 years)
Quality monitoring
of surface
water.
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
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
Long-term
(10 years)
Monitoring of water
quality and its suitability
for different uses
Examine the quality of the water
in facilities where there are wells
for human supply and classify this
according to fitness for use
All wells in sites under management
by UPM-FO
2010 Systematic start-up.
Annual
Monitoring of water in
the area of influence of
the Santana Nursery
Establish a base level for water
quality prior to the installation of the
nursery and monitor the long-term
evolution
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.
