traps were set in lines, one in the forest and another
along the riverbanks, in the shrubs.

upstream the confluence with Aleu Valley
(46°58764 N, 22°60252 E) - 16 traps were set in a
rectangular net in the beech forest on rocky limestone
substratum. The last night a 6 trap line was also set
along the left river bank.
4. 18 - 21st of August 2005 - Scăriţa forest range
- 35 traps were placed in two rectangular nets in the
spruce forest on the right and left sides of the road.
Some traps were set around and in the forest range.
5. 20-22nd of August and 23-26th of September
2005 - Ordâncuşa Gorges - Poarta lui Ionele Cave
(46°45886 N, 22°82787 E) - 30 traps were placed in
lines, on the left bank of Ordâncuşa River, of its
tributary that springs from the cave, and in the broadleaf
forest close to the cave.
6. 21-23rd of August 2005 - Padiş Plateau - next
to Padiş Chalet - 32 traps were set in two lines, one
on the right river bank and one in the spruce forest,
at 10 m distance from the previous.
7. 23-24th of August 2005 - Casa de Piatră
Village - Gârda Seacă Valley (46°52990 N,
22°78731 E) - was researched a felling caused by wind
in a spruce forest southwards Casa de Piatră, using 20
traps.
8. 21-26th of September - Vârtop Pass - Arieşul
Mare River springs area (46°30967 N, 22°40009 E)
- the first two nights 50 traps were placed half in a
rectangular net in a mixed forest and half in a line
along the Arieşul Mare River bank. The next nights
20 traps were set in a thined out mixed forest.
9. 28-30th of September - Horea village - at the
confluence of Ploşiţa and Bulz rivulets (46°30'25''
N, 22°55'47'' E) - 22 traps were placed in a line on the
bank and at the edge of a young spruce and birch
forest.
Results and Discussion
During the research period totalizing 654 trapnights,
22 small mammals belonging to 8 species (3 of
insectivores and 5 rodents) were captured. For 5
species there are direct or indirect evidence on their
presence in the area. In the literature are cited other 5
insectivore and rodent species. Thus, up to the
present, 18 species of small mammals are known to
live in the Apuseni Natural Park and the
neighbouring areas.
Ordo INSECTIVORA Bowdich, 1821
Fam. ERINACEIDAE Bonaparte, 1838
1. Erinaceus concolor Martin, 1838
Is a wide spread insectivore found from the lowlands
up to the mountain feet, especially in shrubs and
forests, being common in the gardens and balks. One
of the main threats this species faces are the road
77
accidents, the only specimen observed during this
study being killed by a car on the road to Pietroasa.
Fam. SORICIDAE Gray, 1821
2. Sorex araneus Linnaeus, 1758
Is the most frequent and abundant insectivore
species in mountain areas. In some years with low
densities of rodents, in habitats that meet its
ecological requirements, it becomes the dominant
species in the small mammal community, reaching
a high abundance. During this study S. araneus was
captured only in two stations, in the beech forest
from Crişul Pietros river bank and at Horea,
where the two individuals were the only captured
animals. In literature is mentioned by V. Banaru
and I. Coroiu (1997) from Beliş (13 specimens).
3. Sorex minutus Linnaeus, 1766
Usually less frequent and abundant than S. araneus,
they appear commonly in the same area and even
habitat. One single specimen was captured, on the
Crişul Pietros river bank. Up to the present it was not
mentioned in the area of reference.
4. Sorex alpinus Schinz, 1837
Is characteristic for the forested mountain habitats,
shady, moist, with rich vegetation. It was seldom
captured by zoologists, presenting in most years very
low densities. However, it is probably more
widespread than it appears from the literature. The
species was cited only at Beliş (Banaru and Coroiu,
1997), 6 specimens being captured (1997 was
probably a peak year for the species). There are also
some verbal reports regarding its presence in the area:
T. Ceuca mentioned it from Irişoara and I. Coroiu at
Scăriţa-Belioara (Banaru, 1998).
5. Neomys fodiens (Pennant, 1771)
Is an aquatic species, inhabiting the mountain
river banks (seldom in the hill and lowland areas)
with clean water and rich vegetation. During the
researches N. fodiens was found on the river bank
in two stations, namely in Crăiasa Valley and
Ordâncuşa Gorges, in the latter both in August
and in September. It was previously encountered
at Răcătău, where it was captured in a relative
high number - 17 specimens (Banaru and Coroiu,
1997).
6. Neomys anomalus Cabrera, 1907
Appears in all the regions of Romania, from lowlands
up to mountains, in the same habitat types as N.
fodiens, but in lower population densities. The single
record of the species in the Apuseni National Park
area is from Drăgan Valley (Hamar and Kovács,
1964).
7. Crocidura leucodon (Hermann, 1780)
Is common in the open areas from lowlands up to the
Subcarpathians. Exceptionally it can be found also at
higher altitudes, beyond the upper forest limit. In the
park area it was mentioned only from Răcătău - 7
specimens (Banaru and Coroiu, 1997).
