Phragmites and Cladium on S'Albufera de Mallorca
Phragmites australis and Cladium mariscus are the two most extensive dominant species in the marshes of the Albufera. A preliminary study was made in April 1990 of the above-ground biomass of the marsh vegetation at 10 locations within the Albufera. On 7 sites the biomass of Phragmites ranged from 7...

| Resumo: | Phragmites australis and Cladium mariscus are the two most extensive dominant species in the marshes of the Albufera. A preliminary study was made in April 1990 of the above-ground biomass of the marsh vegetation at 10 locations within the Albufera. On 7 sites the biomass of Phragmites ranged from 72-792 g dry weight m-2, representing 72-99% of the total. At three sites the Cladium biomass varied from 18-392 g dry weight m·2 representing 90-100% of the total. The leaf area index (area of leaf per unit area of ground) of Phragmites ranged from 0.5-2.3, of Cladium from 1.5-4.3. The morphology and seasonal growth patterns of the two species are strongly contrasting. Phragmites shoots, especially on sites which have not been burned for several years, are attacked by the caterpillar of the moth Archanara geminipuncta which causes the death of the apical shoot, encouraging the development of lateral shoots. In some areas more than half the stems are affected. Further studies on the productivity of Phragmites and Cladium have been carried out on four sample dates in 1991. |
