Euxine–Colchic broadleaf forests
Ecoregion
The Euxine–Colchic broadleaf forests is an ecoregion of temperate broadleaf and mixed forests along the southern shore of the Black Sea. The ecoregion extends along the thin coastal strip from the southeastern corner of Bulgaria in the west, across the northern coast of Turkey, to Georgia in the east, where it wraps around the eastern end of the Black Sea.
Sub-regions
The ecoregion is divided into two sub-regions, chiefly based on the amount of precipitation.
The understory of evergreen broadleaf shrubs is characteristic for both sub-regions. Notable species in the understory include various rhododendrons such as Pontic rhododendron (Rhododendron ponticum); Black Sea holly (Ilex colchica), cherry laurel (Prunus laurocerasus), Caucasus (Buxus colchica) and common box (Buxus sempervirens), Caucasian whortleberry (Vaccinium arctostaphylos) etc. From a European perspective, the majority of these count as relict species from the Tertiary period.
Colchian forests
The Colchic or Colchian forests are found around the southeast corner of the Black Sea in Turkey and Georgia in and around the Machakhela National Park. The Colchian forests are mixed, with deciduous black alder (Alnus glutinosa), hornbeam (Carpinus betulus and C. orientalis), Oriental beech (Fagus orientalis), and sweet chestnut (Castanea sativa), together with evergreen Nordmann fir (Abies nordmanniana), Caucasian spruce (Picea orientalis) and Scots pine (Pinus sylvestris). Platanus orientalis is also found in these areas. The vegetation is diverse and varies with elevation.

Why this record matters
The phrase “ecoregion” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 4, 2025. The linked authority identifier is Q3847917. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
