27.05.2022 within KSM Nowogród Bobrzański on piles of branches that we had erected we observed many Sand Lizards (Lacerta agilis argus). It shows that our actions bring results. An adult female of that species was seen at a heap of sawdust. Perhaps she will lay eggs there or has already done so.
Tail of one of juveniles was very short, regrowing after autotomy. We were happy to find another lizard species of the quarry - Slow Worm (Anguis fragilis). This harmless, legless, secretive lizard is at times mistaken for a snake.
The pond was full of European Water Frogs (Pelophylax esculentus complex), males of which were croaking and actively looking for females. Under water there were much more inconspicuous but no less interesting amphibians - larvae of Smooth Newt (Lissotriton vulgaris) and Grass Frog (Rana temporaria). The former are endowed with external gills and fins - adaptations to aquatic life. They prey on aquatic invertebrates like copepods and water fleas. Tadpoles, on the other hand, feed on algae, therefore they help clean the water.
In a reference forest stand adjacent to the quarry we observed a Grass Frog. They are sometimes prayed upon by Grass Snakes (Natrix natrix) that are also present in the area.
