Bassin de Боржава
A watershed (drainage basin) is not a body of water — it is the land area where rainfall converges towards a single river that eventually reaches the sea (or an endorheic basin). Boundaries follow ridgelines.
Crosses 10 administrative regions across 2 countries : Berehivs'kyi, Irshavs'kyi, Khusts'kyi, Mizhhirs'kyi, Mukachivs'ka +5

Ecological tissue
Sample of 38 species (selected proportionally per kingdom among those with at least one documented interaction here) to keep the graph readable. Hover for details, click to explore the full ecosystem of a species.
ℹ️ The territory contains many more species than displayed and all their documented interactions: the graph is intentionally the structural skeleton (top-N species by composite local score, edges filtered by Serrano 2009 disparity filter α=0.2).
Indicateurs du tissu écologique
Tissu écologique de Bassin de Боржава : 27 espèces dont 2 patrimoniales (LR IUCN CR/EN/VU) reliées par 154 interactions GloBI sur 5 types (connectance 19.7%, filtre Serrano α=0.2). 13 bulles taxonomiques (cascade genre/famille GloBI, ≥3 espèces).
