Lake Myvatn and the River Laxá

Updated 2001-04-20

The aim is to monitor the Lake Myvatn and the river Laxá ecosystem for (1) detecting trends, (2) detecting background variability in the system, (3) assess the efficiency of management measures, (4) observe perturbations in order to generate hypotheses about causal relationships.

This is not a National Implementation Plan (NIP) project
