1. OLD GROWTH - By studying old-growth forests for decades, Andrews' scientists discovered that these systems with their large, old trees and specialized plants and animals that rely on them are vital and unique components of a healthy landscape. This understanding has transformed the way that old-growth forests are conserved and managed today.
2. RIVER CONTINUUM - By expanding river research from small streams to whole rivers, Andrews' scientists made key contributions to the "The River Continuum Concept." This Concept transformed our understanding of rivers and their restoration by describing crucial linkages between rivers and their banks along their entire lengths - from headwaters to the mouth of intact river systems.
3. THE ECOSYSTEM VALUE OF DEAD WOOD - Andrews' scientists revealed the importance of dead trees to diversifying animal habitat and sustaining the flow of vital nutrients in forests and streams by tracking how fallen and standing deadwood changes as forests age. These studies profoundly influenced forest management by prioritizing the retention of dead wood in forests and streams.
4. TEMPERATURE PATTERNS - Andrews' scientists have discovered how cold air in mountainous terrain can sink into valleys and become trapped in the forest canopy. This creates a complex microclimate that is often disconnected from surrounding weather patterns and has important implications for how mountain forests will respond to climate change.
5. SCIENCE & POLICY - The results of Andrews' research has sometimes been in conflict with contemporary forest and stream management policies and practices. By working with policymakers and managers to develop new, science-based policies and management plans, Andrews' scientists have helped to transform the roles that forest scientists play in society.
6. ART AND NATURE -- Scientists at Andrews have created innovative programs that bring together scientists and writers, artists, philosophers and other humanists, leading to new programs such as Long-Term Ecological Reflections, emulated widely. The blending of science and humanities is helping to transform the way we relate to and understand the natural world.
