study proposes a methodology to quantify the environmental impacts
of forest operation based on the synthetic distance P2
(DP2) indicator. This indicator integrates
a number of qualitative and quantitative variables related to debris
management, skid trails, landings, streams, harvested areas and
the percentage of exposed mineral soil.
sample of 43 sites located in the land properties of the following
companies: Forest Company 1, Forest Company 2, Forest Company 3,
and Forest Company 3, from Chile, were assessed since November 15th
to December 24th 1998 according to environmental guidelines.
from the environmental evaluation method proposed (DP2)
a sustainability value as objective as possible was obtained for
each of the evaluated sites, that is to say, a vector of a synthetic
indicators, which made possible to carry out spatial compares among
the sites and the companies, with the purpose to assess its environmental
behavior. Beginning with the vector of synthetic indicators DP2
an explanatory model was obtained, which allows to obtain an environmental
sustainability value in any site.
with the results, the highest value of the DP2
was 34,81 in site 31, because of the great alteration of the buffer
zone by excessive traffic of harvest equipment. On the other hand,
the company number 2 had the lowest environmental behavior due to
the high values of DP2 registered. However,
the company number 3 was nearest to the waited objective (ideal
condition). Finally, of the set of variables considered the most
relevant, that is to say, the ones that obtained a greater level
of non conformity where those variables related to stream.
