Reintroduction of oak species into the Ciuc Basin

We initiated the reintroduction of the oak (Quercus sp.) species into the Ciuc-basin.

Until the 17th century, oaks were widespread here, but they disappeared due to anthropogenic causes - firewood harvesting, converting large areas for agriculture. The place of the former oak forests was occupied by pastures, hayfields, arable land.

Due to socio-economic changes in rural areas, many former agricultural land is abandoned and the surface of these abandoned marginal agricultural land increases every year. A slow natural reforestation process is beginning, but the sources of propagules (acorns) are no longer present nearby, the natural recolonisation of these lands by the oak (Quercus sp.) species will not be possible without anthropogenic intervention.

Beside their historic presence in the Ciuc Valley, these tree species are especially valuable because

  1. Sessile oak (Quercus petraea) and pedunculate oak (Quercus robur) are among the few tree species that will be resistant to the expected effects of global climate change (extended drought periods and milder, dryer winters) and their range will probably expand.

  2. Oak forests sustain a high level of biodiversity

  3. Oak trees are a long-living tree species, storing in their biomass significant amounts of atmospheric carbon sequestered by photosynthesis during the growing season.


The small planted oak groves will function as ecological stepping stones, helping the trees to slowly recolonise the abandoned agricultural lands with the aid of birds (especially jays).

Earth day plantings in April 2023 near Sandominic village.

In the planting season of the year 2022 we have planted  an oak grove near Bancu village.
