Abstract(s)
The aim of this study is to understand
how the daily grazing paths of sheep
and goats in the silvopastoral systems
of the North of Portugal are connected
with the rural landscape. For this purpose, A herd of sheep and a herd of goats
were monitored with GPS every month
during one year in order to record their
geographical position. The total data
includes 3210 GPS positions, 1948 for
the goat's ock and 1262 for the sheep
ock. A GIS was used to identify the
land cover class of each GPS position
on the thematic map COS 2007 published
by Portuguese Geographic Institute
(http://www.igeo.pt). The land
cover selection/rejection was estimated
by the Krueger’s preference index
(Krueger 1972). The discriminant analysis
was used to determine which land
cover classes discriminate between
sheep and goats herds. Discriminant
functions analysis was used to classify
the sheep and goats positions and
paths in order to distinguish the grazing
landscapes of sheep and goats.
it was assessed and compared
the land cover types used by sheep and
goats herds.
