Fagus sylvatica trees are older than 350 years in Izvoarele Nerei and even 500 years in Uholka-Shyrokyi Luh. Spring leaf budding by the European beech is triggered by a combination of day length and temperature. Bud break each year is from the middle of April to the beginning of May, often with remarkable precision (within a few days). It is more precise in the north of its range than the south, and at than at sea level. The European beech invests significantly in summer and autumn for the following spring.

Cepaea sylvatica these snails is smaller than that of grove snails; the brown area is continuous; and the spire of the shell is blunt. Cepaea sylvatica " Cepaea sylvatica" is a medium-sized species of air-breathing dextral land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae.

This species lives in many of the same habitats as "Cepaea nemoralis", such as woods, dunes and grassland, however "C. sylvatica" tolerates wetter and colder areas than the grove snail can tolerate. "Cepaea sylvatica" is generally similar in appearance to "C. nemoralis", although the
