Threatened herbaceous-dominated habitats

Nature

Threatened herbaceous-dominated habitats are ecosystems primarily composed of non-woody plants, such as grasslands, meadows, and savannas, facing significant risk of degradation or loss. These habitats are endangered due to factors like agricultural expansion, urbanization, invasive species, pollution, and climate change. Their decline leads to reduced biodiversity, loss of ecosystem services, and diminished habitat for numerous plant and animal species. Conservation of these habitats is critical, as they support unique ecological communities, contribute to soil health, and play a vital role in carbon sequestration and water regulation. Their ongoing threat represents a significant environmental concern globally.

Background

The global decline of herbaceous-dominated habitats, such as temperate grasslands, savannas, and wildflower meadows, first drew scientific concern in the mid-20th century as agricultural expansion and land conversion accelerated. Subsequent ecological studies highlighted their critical biodiversity and ecosystem services, prompting international conservation attention. By the 1990s, alarming rates of habitat loss and fragmentation were documented worldwide, leading to their recognition as some of the most threatened and least protected terrestrial ecosystems.

Incidence

Herbaceous-dominated habitats, such as temperate grasslands, savannas, and wildflower meadows, are among the most threatened ecosystems globally, with over 40% of temperate grasslands converted or degraded due to agriculture, urbanization, and invasive species. The loss of these habitats has led to significant declines in plant and animal biodiversity, soil health, and ecosystem services, making their conservation a matter of international concern.
In 2022, the Ukrainian steppe, one of Europe’s largest remaining herbaceous-dominated habitats, suffered extensive damage from military activities, wildfires, and land conversion, resulting in the loss of thousands of hectares of native grassland.
