Explanation:

Xerothermic grasslands are herbaceous plant assemblages of a grassy or grassy-herbaceous character. The term "grassland" is commonly used to refer to a general assemblage of herbaceous plants, which is not exactly correct. There are other herbaceous habitats that do not have trees, such as meadows, but these are not dry grasslands. To simplify matters, an area of plant assemblages can be called a grassland if it includes species that developed in various extreme conditions, such as, for example, on a soil substrate with little water or organic matter (xerothermic and thermophilous) or a high salt content (salt grasslands), on soil with a high concentration of heavy metals (calamine grasslands) or strongly calcareous (chalk grasslands).

Xerothermic grasslands are primarily found in southern and southeastern Europe. In Poland, they are most frequently located on sunny slopes with a dry and alkaline substrate. Convenient sites may be hillsides, ravines, the steep slopes of river valleys, permanent talus piles at the base of chalk cliffs. Accordingly, the plants making up this type of phytocoenosis are photophilic and calciphilic. They have adapted to living in dry alkaline or neutral soils, rich in calcium carbonate but poor in organic matter and moisture.

In Poland, these are most often partly natural habitats that developed in response to specific agricultural activities. For several hundred years, their establishment and maintenance in the landscape was connected to animal grazing or prescribed burning. Today, they are mostly wastelands. It should be noted here that in terms of ecological succession, grasslands are a short-lived stage on the way to a more complex set of plants, such as forests and shrubs. Xerothermic grasslands are therefore not a climax assemblage of plants. They dominated in our climatic zone after the last ice age, when they were able to take advantage of the vast expanses of unforested space. Then, over hundreds of years, they gradually succumbed to succession. Currently, the careful intervention of humans in the form of extensive grazing is needed in order for them to be maintained. The exception is only those grasslands, which exist in such extreme conditions that natural succession by shrubs and trees is precluded. An example of this is the upper montane area of the Tatra Mountains, where alpine calcareous grasslands exist.

It should be remembered that plants adapted to many unfavorable habitats as the result of evolution and competition. Today, in an era of maximizing profits, fertilization and agricultural intensification, infertile land is not farmed. It is either afforested or abandoned. This is why sites that could potentially support this group of plants are systematically shrinking. Due to the many factors impacting their survival, xerothermic grasslands are among the most threatened plant communities in Europe.
