This tutorial provides an introduction to concepts of hierarchy and scale and their importance for understanding socio-environmental systems. Learning Goals include:
•    Understand the hierarchical nature of complex systems.
•    Define what scale means and describe why it is a critical consideration for understanding systems.
•    Identify relevant scale dimensions of an S-E system, including spatial, temporal, and structural dimensions.
•    Understand what cross-scale linkages are and why they are important to understanding S-E systems.
•    Be able to explain what scale mismatch is and why it is an important consideration in studying S-E systems.
