Figure 2. Visualization of classification results from 1992 image (A) and from 2000 image (B).
4. Results and Discussion
Both images contain same number of pixels (1,364,200). The
dispersion (as percentage) of total pixels that constitute the field
of study according to the terrain types determined for each year
is shown in Table 2. The change in forest areas belonging to
each year is negative (-5.6%). This percentage is 6.31% for
agricultural and idle areas. Considering these results, the change
in Bartin province and its vicinity is the transformation of the
land into agricultural areas. Furthermore, the increase in
residential areas (0.3%) is the result of construction activities in
recent years. The decrease in the amount of sandy-stony-rocky
areas (0.46%) is the result of dense industrialization and
construction activities in these types of areas. in Bartin forests,
there are three different forest management units; high forest,
unproductive high forest, unproductive coppice (Table 3).
According to the investigations made on crime files, which were
documented by Bartin Forest Directorate, most of the crimes
were observed in areas belonging coppice management unit.

The reason of high forests being more damaged than
unproductive high forest is that high forest occupies 3.2 times
more area than the unproductive high forest. Also, the reason of
having the most damage on coppice area is not to provide
enough revenue and not to take care of forest by forest
directorates. In order to keep coppice areas safe which are
damaged by forest villages continuously, these forest areas must
be rehabilitated and converted to high forest. Nevertheless, in
this case protection measures will be increased and this forest
will face less negative effects. When looking at the illegal
activities stem from forest villagers to the forested areas in
terms of the canopy and management unit, it was observed that
coppice having 1096-4096 canopy degree has been experienced
the most severe damage. High forests having 41%-100%
canopy degree had no damage at all. Another reason of attack in
these forest areas is being near to agricultural or settlement
areas. Social-economic structure of the people in those areas
brings such a result.
