Evidence

Peer-reviewed

Geography

Three streams in the Cameron Peak Fire scar, Colorado, USA

System

Post-fire stream nutrient cycling and geomorphology

## WHAT THE EVIDENCE SAYS

Factorial nitrogen/phosphorus additions above and below low-gradient river segments showed downstream nitrogen response during low flow, but stronger upstream co-limitation during high flow. Macroinvertebrate grazer density also affected the algal chlorophyll response.

## WHY IT MATTERS / OUR READ

Geomorphic position and grazers modify nutrient consequences of wildfire; one downstream station can miss important contrasts.

## CAVEATS / UNCERTAINTY

Three fire-scar streams, local nutrient-diffusing substrates and chlorophyll response; not a direct whole-river restoration measure.
