 rld's surface freshwater. Many of these changes are linked to watershed di
 sturbance. This is because aquatic ecosystems are fuelled by biogeochemica
 l cycles that initiate on land. But terrestrial land use and disturbance a
 re frequently overlooked when managing freshwater supplies. Here\, I will 
 show how the biology\, chemistry\, and physics of small boreal lakes\, whi
 ch store most of the world's freshwater\, are controlled by terrestrial ve
 getation in their surrounding catchments. A consistent finding is that key
  services delivered by aquatic ecosystems\, such as productive fish popula
 tions and accessible drinking water supplies\, are ultimately products of 
 healthy forests and wetlands. High forest cover may even help increase the
  resilience of systems to climate warming. Conservation of freshwater ecos
 ystems clearly needs to protect local watersheds and coordinate the manage
 ment of fisheries and forestry resources.
