individuals/ha), Spartium junceum (1,300 individuals/ha), Coronilla emeroides
(1,000 individuals/ha), Cistus salviefolius (800 individuals/ha), Arbutus
unedo (700 individuals/ha), Pinus pinaster (700 individuals/ha), Cistus villosus
(600 individuals/ha), Ligustrum vulgare (400 individuals/ha), Prunus

vitalba (300 individuals/ha), Crataegus transalpina (200 individuals/ha) and
Phillyrea latifolia (100 individuals/ha). Together with Rubus dalmaticus,
these make up 19 woody species (Figure 1). A total of 70 plant species were
registered in the open strips (Table 1). The game made use of 35 of them for
their feed (50 %). In terms of the number of species and forms in the experimental
plots, there were 53 % of herbaceous plants, 27 % of woody plants and
20 % of grasses and sedges. However, in terms of the proportion of the species
within the consumed species, the ratio is somewhat different. Herbaceous
plants account for 60 %, woody plants for 29 % and grasses and sedges for
11 % (Figure 2). With regard to the ratio of consumed and non-consumed species
in the categories of herbaceous plants, grasses and sedges and woody
plants, the situation is as follows: of a total of 37 herbaceous plants, 21 are
consumed by the game (57 %), of 19 woody plant species, 10 (53 %) are used
by game, while of 14 kinds of grasses only 4 (29 %) are consumed. The most
preferred species (Table 3) was Raphanus raphanistrum -Pi = 4.24, followed
by Picris hieracioides -Pi = 3.99, Senecio erraticus -Pi = 3.84, Verbena officinalis
-Pi = 3.78, and Daucus major -Pi = 3.54. The most preferred woody
species was Coronilla emeroides, which took the sixth place (Pi = 3.39),
while among the grasses, the most preferred was Holcus lanatus, taking the
25th place (Pi = 0.71). The importance of open strips, that is, their maintenance
in the Mediterranean area is highly significant not only as a source of
game food, but also as a defence against possible fires. The maintenance of
open strips is gaining increasing importance from the standpoint of hunting
economy, because their mowing provides relatively good quality pasture.
Thus, it is not necessary to clear and cover forest areas with grass in order to
ensure sufficient forage for the game. All consumed plants in the sample had
poor nutritional value, which ranged from poor to very harmful (for example,
Senecio erraticus,). It is important to point out that oculary inspection of the

faeces in the hunting ground did not reveal any digestive disorders, which
means that the game uses the depressive, harmful and very poisonous plants
in the optimal manner. Accordingly, game is a more economic consumer of
the neglected area than domestic animals. In order words, in terms of using
natural nutritive resources, game converts plants into meat, trophies, hide
etc, more economically, and therefore, not much investment is required to
improve the sites.

Key words: open strips, openings, moufflon (Ovis ammon musimon
