The paper approaches the problem concerning the protection of chiropteras from Romania, first of all pointing out the main causes which led at the decrease of bats population from their natural environment, especially from caves. These causes are loss of natural habitats, disturbance of colonies, reduction of food resources and environmental destruction. That state of fact is illustrated by the actual situation of some caves from Romania, which half a century ago were the habitats for thousands of bats from many species and in present are the shelter for only few. The caves «Igrita», «Muierilor» and «Liliecilor de la Mânastirea Bistrita are only some of the most known caves where the number of bats decreased considerably. Other caves, as «Pisnita» were completely left by bats. The international norms will be presented, mainly the European ones, which refer to the protection of the bats species and their habitats. The laws adopted by our country are also discussed: the Law of Romania’s Adhesion to the Convention concerning the Preservation of Wild Life and of the Natural Environment from Europe, entered into force on 11 March 1993 and the Law of the Environmental Protection, came into force on December 1995. For the efficient conservation of bats we consider that the priorities are the protection of the natural environment by avoiding the perturbation of the colonies, by avoiding the destruction of entomological fauna, the maintenance of the environment quality standards. The promoting of the informing programmes and people educational process in order to preserve this great treasure which is wild life are very important, too.

1999 Borda Daniela, The distribution of bats in Romanian caves, Travaux de L' Institut de Spéologie «Emil Racovitza», XXXVIII, Ed. Academiei, Bucuresti (in press)
This paper presents the first results of a larger project regarding the distribution of the chiropteras in Romania’s caves. The investigations were made in certain areas in Apuseni Mountains (Transylvania), and in Meridional Charpatic Mountains. The presence of the Chiroptera species is presented in the UTM codes. Some remarks regarding the frequency of the species in the investigated areas and their abundance are discussed

On the basis of a skeletal found in a Cave from Bihora Mountains, Myotis brandtii Eversmann, 1845, a new species recent recorded in Romania, is discussed. Some cranial features and measurements are examined comparatively with bibliographical data of other two species of ‘mystacinus group: Myotis mystacinus Kuhl, 1817 and Myotis ikonnikovi Ognev, 1911. It also points out the actual situation of these species, including their distribution, in Romania.

Surveys of bats dynamics, temperature and humidity were performed monthly during one year in a Romanian cave. Myotis myotis, Miniopterus schreibersii, Rhinolophus ferrumequinum and R. hipposideros were observed in this cave. The location of the colonies in the cave depends on the two above-mentioned physical factors and also on the wall structure and underground ventilation. The air microorganisms determined show the direct relation with bats, with pronounced air infestation near the nursering colony during summer.

Among the 31 bat species found in Romania in the last century, 19 of these are recorded in the Padurea Craiului Mountains. For several of the species found in the different caves of this area we described the most important cranial measurements. The most frequent species were Myotis myotis (55,55%), Rhinolophus ferrumequinum (55,55%), R. hipposideros (50,00%) and Miniopterus schreibersii (38,88%), while the most abundant were the sibling M. myotis / M. blythii, R. ferrumequinum and M. schreibersii. A few of the important bat caves and their status are also presented. Data recorded indicates there are no critical changes in bat populations In accoedance with this assessment, most caves (Meziadului, Ungurului, Valea Lesului, Vadu-Crisului) and generally the entire region still represent a natural, unpolluted place for bats.
