leolomaa

Leolomaa is a geographical term referring to a specific type of calcareous grassland found in the Baltic Sea region, particularly in Estonia. These grasslands are characterized by their thin, calcareous soil, which is derived from limestone bedrock. The thin soil layer and alkaline conditions create a unique microhabitat that supports a specialized flora, including many rare and protected plant species.

The vegetation in Leolomaa is typically low-growing and drought-resistant, adapted to the nutrient-poor and dry conditions. Common plant species include various grasses, sedges, and herbs such as oregano, thyme, and wild thyme. Certain orchid species also thrive in these environments, contributing to the rich biodiversity of Leolomaa sites. The presence of specific plant communities is a key indicator for identifying Leolomaa.

Leolomaa grasslands are often found on south-facing slopes or elevated areas where water drains away quickly. Historically, these areas were maintained through traditional grazing practices, which prevented the encroachment of trees and shrubs, thus preserving the open grassland habitat. The decline of traditional land use has led to increased pressure on these fragile ecosystems, with some areas becoming overgrown. Conservation efforts focus on restoring and maintaining these characteristic grasslands through methods like controlled grazing or mechanical clearing to preserve their unique biodiversity.
