DUŻA LICZBA MARTWYCH ZASKROŃCÓW ZWYCZAJNYCH NATRIX NATRIX NA LOKALNEJ DRODZE
Journal Title: KULON - Year 2016, Vol 21, Issue
Abstract
On 3 October 2015, on the local, asphalt road Borek – Pagowiec (51°35’40’’N, 21°0’47’’E, Central Poland), 74 dead grass snakes Natrix natrix (0.8 ind./10 m) were found, and two alive on the road side. The inventory was conducted along the road section of 916 m. Young and adult snakes were present. This road section separated a peatland of about 200 ha from fragments of a pine forest. Observation of such a high number of dead individuals could be an indication of migration to their overwintering sites, or of the use of warm asphalt. On that day, the air temperature was high, +20°C. This was one of the last three warmest days in 2015 (Figure).
