Stammmäntel

Stammmäntel, a term derived from German, literally translates to "stem coats" or "trunk sleeves." In botanical and ecological contexts, it refers to the protective layer or sheath that surrounds the base of a plant's stem, particularly the trunk of trees. This layer serves multiple vital functions for the plant's survival and health.

Primarily, stammmäntel protect the cambium, the actively growing tissue responsible for secondary growth in woody plants, from physical damage. This damage can be caused by various environmental factors such as abrasion from wind-blown debris, animal gnawing, or even harsh weather conditions like ice accumulation. The stammmantel acts as a barrier, absorbing these impacts and preventing injury to the delicate inner tissues.

Furthermore, stammmäntel play a role in preventing water loss from the stem surface, especially in arid or exposed environments. They can help to regulate the stem's microclimate, providing a more stable environment for the underlying tissues. In some species, the stammmantel may also be involved in the storage of nutrients or water, contributing to the plant's overall resilience. The composition and appearance of a stammmantel can vary significantly between different plant species, ranging from thick, corky bark to more fibrous or layered structures.
