Resumen:
Since the 1940s, some sectors of the sand
dune barriers of Buenos Aires Province have been
forested to fix the sand in the neighborhoods of
resort villages. Man took advantage of the maritime
climate and the shallow groundwater to introduce
pine forests. Today, these forests reach more than
20 m in height and have developed soils of more
than 0.05 m in thickness on former arid sands. Field
data were referred to Landsat (TM) composite and
Normalized Difference of Vegetation Index, NDVI,
images to calculate forest density and covered area.
Considering published tables of wood density for
each species, the amount of total carbon storage was
estimated on 318 t C ha
-1
(Mg=10
6
g) in biomass
and 86 t C ha
-1
in soils. The three areas analyzed at
Miramar, Necochea and Claromeco´ have captured
658,868 t of carbon in the last 50 years. It is
estimated that 150,000,000 t C could be sequestered
within temperate dune barriers of Argentina,
Uruguay and Brazil. Besides this ecological point of
view, there is an important socio-economic factor
that cannot be excluded.
