The LTER Network has grown from a handful of independent sites to a true network with cross-site experiments, synthetic science, coordinated data management, and standard community practices. LTER community members managed a great deal of that growth, with modest financial support from the LTER Network Office in the form of working group funds. The record of past working groups is – in many ways – a record of the focus and priorities of the LTER Network through time.
