LT: long-term

Explains the concept of 'long-term'

LTER is long-duration research and monitoring of ecosystems or components of ecosystems. The meaning of ‘long-term’ is defined as the time scale which best enables environmental signals to be discriminated from the background ‘noise’ (Parr et al, 2002). It should also allow encompassing slow processes, rare events or episodic phenomena, processes with high variability, subtle processes, time-dependent processes (e.g. succession), second-phase events and complex phenomena, which cannot be observed and explained by short-term projects. In general LTER programmes last longer than five years, and in many instances, LTER activities run for decades or indefinite periods.
