Seasonal changes in the standing crop of two montane sedges
Aboveground green biomass of a montane pure stand of Carex rostrata varies from about 125 g/m 2 (air-dry weight) at the end of November to about 640 g/m 2 in early August. The maximum production rate of about 6 g/m 2 per day occurs in May. For a nearby stand of Carex aquatilis with a prominent moss...
