Wechselzone

Wechselzone (literally "change zone" or "transition zone" in German) denotes an area or interval in which a change, transfer or transition between two states, systems or conditions takes place. The term is used in several fields to describe physical spaces or conceptual boundaries that facilitate movement, exchange or transformation.

In sport, Wechselzone commonly refers to the designated area in multi-discipline events such as triathlon where athletes change equipment and clothing between segments (for example, from swimming to cycling). It also describes the exchange zone in relay races where a baton or equivalent is passed between competitors; precise rules often govern its size and the timing of exchanges.

In ecology and geography, Wechselzone is used informally to describe transition areas between different ecosystems or land uses—regions where species composition, microclimate or soil conditions shift from one community type to another. Such ecotones can show increased biodiversity and dynamic environmental gradients.

In planning and design, the term may denote buffer zones or transitional corridors that mediate between contrasting urban, agricultural or natural areas, helping manage impacts and connectivity.

As a descriptive term, Wechselzone emphasizes the dynamics of change and the functional role of the space or interval rather than a fixed boundary. Specific definitions and regulations depend on the disciplinary context and local usage.
