Abstract		In this paper, we present a review of distributional data for reptiles in Slovenia collected prior to April 2009. Data are presented in a 10x10 km UTM grid and divided into two classes by the age: 1995 or earlier, and 1996-2009. With this review, we would like to create a basis for future field work and emphasize the distributional gaps. For some species, the knowledge of their distribution has increased substantially in the last 13 years (e.g. for Podarcis muralis, Vipera aspis, Zamenis longissimus, Anguis fragilis, Natrix natrix, N. tessellata, and Lacerta viridis / bilineata). The increase in some introduced species (e.g. Trachemys scripta and Testudo hermanni) is probably a consequence of additional introductions by people. On average, the number of UTM squares with recorded presence of autochthonous species has increased by 12% per species after 1995. For some of the species, no more records have been made after 1995 in many areas where they had been recorded before (e.g. Podarcis melisellensis, Vipera ammodytes, V. berus, Emys orbicularis, and Lacerta agilis), which might indicate the possibility of local extinctions. For the future, we recommend a continual monitoring of the population trends concerning individual species.
Summary		V prispevku podajamo pregled podatkov o razširjenosti plazilcev v Sloveniji, zbranih do aprila leta 2009. Podatki so predstavljeni na mreži UTM-kvadratov 10x10 km in razdeljeni glede na čas najdbe na obdobje pred letom 1996 in obdobje od 1996 do 2009. S tem prispevkom želimo postaviti osnovo za nadaljnje zbiranje podatkov na terenu in opozoriti na območja s pomanjkljivimi podatki. Pri nekaterih vrstah se je poznavanje njihove razširjenosti v zadnjih 13 letih precej izboljšalo (npr. Podarcis muralis, Vipera aspis, Zamenis longissimus, Anguis fragilis, Natrix natrix, N. tessellata in Lacerta viridis / bilineata). Pri nekaterih alohtonih vrstah (npr. Trachemys scripta in Testudo hermanni) je povečanje števila UTM-kvadratov z zabeleženim pojavljanjem po letu 1995 najverjetneje posledica njihovega vnašanja v naravo s strani človeka. V povprečju se je število UTM-kvadratov z zabeleženim pojavljanjem posamezne avtohtone vrste po letu 1995 povečalo za 12%. Nekaterih vrst na mnogih območjih po letu 1995 nismo več našli (npr. Podarcis melisellensis, Vipera ammodytes, V. berus, Emys orbicularis in Lacerta agilis), kar nakazuje na možnost lokalnih izumrtij. V prihodnje bi bilo zaželeno zagotoviti stalen monitoring, s katerim bi lahko zanesljiveje beležili trende v populacijah posameznih vrst.
