Natural habitat and vegetation types of river gravel bars

Jun 12, 2020River gravel-bar habitats are highly endangered. They are still well-preserved in the Caucasus, but developing conservation strategies is burdened by the lack of data from this region.

Features of soil

Individual soil aggregates may have differing shapes. Some aggregate shapes indicate better soil structure from a plant-growth point of view. Platy structure is likely to restrict air and water movement and thus reduce plant growth. Crumb-type aggregates allow good plant growth because there is good water and air movement.
