Abstract

Background and objectives
Gandoman wetland is one of the top ten wetlands in Iran, Chaharmahal va Bakhtiyari province. This wetland is an important system that contains a vast array of plants and animals and help regulate the climate, as well as provide flood and erosion control, while at the same time storing and recycling nutrients. Unfortunately, in recent years, due to human interventions, climate changes and improper management, many changes have occurred in this wetland. Therefore, in order to economically value their services and functions, and consequently to optimally utilize vegetation cover and achieve a sustainable management plan, these changes must be identified and evaluated. This study was conducted with the aim of evaluating vegetation cover indicators (percentage of canopy cover and biomass of different habitats of Gandoman Wetland.
Material and methods
For this purpose, different types of the vegetation cover of the wetland were identified. Three transects with a length of 100 m were installed in each plant community. Depending on the plant community and the vegetation cover distribution and the distances between plant points were 50 to 100 meters. Each transacts contain three plots 1×1 were identified. Totally, 30 plot 1×1 were installed in each plant community and the percentage of canopy cover, aerial biomass of plant species, bare soil percentage, density and litter were estimated. The double-sampling method and relationship between the percentages of canopy cover with aerial biomass of plant species of plant species were estimated for forage yield.
Results
The results showed that there are five types of plants in the wetland. Phragmites australis-Carex riparia was frequent dominant species in the Gandoman wetland with an area about 52.90 ha. Wetland vegetation cover was 76.02 percentage and total forage yield was equal to 1695.52 grams per square meter. The greatest forage yield was belonged to Phragmites australis species (2986.7 grams per square meter).
Conclusion
In general, considering the significant amount of aerial biomass of plant types, it is recommended, In order to optimally utilize the productive plant cover and also maintain the sustainable balance of the Gandoman Wetland, plant types have been segmented and areas with plants in danger of extinction are fully protected and in areas with high density of vegetation and high susceptibility to fire, balanced, selective, and periodic harvesting methods should be used to create fire suppression, while taking into account environmental considerations.
