| Responding parameter | Carbon acquisition II |
Response description
Early snow melt followed by wet and warm conditions led to high carbon acquisition through photosynthesis.
Specification of relevant ecosystem type
Fen
Relevant ecoregion(s) according to Illies
21 (Tundra)
Suggested indicator
Date of snow melt, temperature and precipitation
Justification of indicator
A combination of early spring plus wet and warm weather promotes vegetation growth. Photosynthesis sequesters carbon, while rates of respiration remain comparatively stable year to year. Thus, carbon is accumulated in these conditions.
