Estimates of Energy Budgets for a Typha (Cattail) Marsh.

Yearly utilization of total solar radiation by a Typha marsh shows approximately equal allotment to reflection (albedo), evapotranspiration, and conduction-convection. Reflection during the growing season is proportionally lower because of greater light absorption by the vegetation. Photosynthesis is a negligible quantity, although in relation to visible radiation during the growing season it nearly equals reflection.
