Which identification method may provide immediate visual recognition but lacks durability?

The identification method that provides immediate visual recognition but lacks durability is temporary plastic tags. These tags are designed for short-term use and are often utilized because they can be easily attached and removed, making them convenient for situations that require quick identification. However, they are not resilient over longer periods and are susceptible to wear and tear, environmental conditions, and handling, which can lead to loss or damage.

In contrast, other identification methods mentioned, such as universal ear notching and slaughter tattoos, are designed for more permanent identification and therefore offer greater durability. Metal ear clips are also more robust compared to temporary plastic tags, providing long-lasting identification that can withstand various conditions. This characteristic of plastic tags makes them ideal for temporary situations, but not for long-term identification needs.
