HydroBASINS lev08 watershed · #2080370050
Bassin de Знобівка
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 6 administrative regions across 2 countries : Iampil's'kyi, Novhorod-Sivers'kyi, Seredyno-Buds'kyi, Sevskiy rayon, Suzemskiy rayon +1

Ecological tissue
Sample of 25 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).
