Species Profile
Gaillet de Thiébaut (Galium thiebautii) is a rare endemic bedstraw species found in specific Mediterranean coastal regions. This delicate perennial herb displays the characteristic whorled leaves and small white flowers typical of the Galium genus, forming low-growing mats in rocky crevices. It plays a specialized ecological role in stabilizing coastal substrates and providing nectar for local pollinators in its restricted habitat.
Galium thiebautii faces severe threats from habitat destruction and degradation due to urban development, agricultural expansion, and invasive plant species in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to local extinctions from human activities and environmental changes.
Key Facts
Habitat & Distribution
This species inhabits limestone cliffs and rocky crevices along Mediterranean coastlines, typically growing in thin soils within 500 meters of the sea. It favors well-drained calcareous substrates in areas with moderate salt spray exposure and partial shade from overhanging rocks.
Threats
