Offered Papers Theme B: Grassland and the Environment
Description
The rapidly increasing human population in Bangladesh has caused widespread damage to and disturbance of natural habitats and a loss of indigenous wildlife. There are now very few, if any, extensive patches of grassland in Bangladesh and any that might remain are inundated for two-thirds of the year with no alternative refugia available. Most remaining grassland areas are fragmented, heavily used and harvested up to three times a year. Furthermore, the reed lands of northeast Bangladesh were leased out for paper production and are reported to have been entirely destroyed and settled by encroachers. Tall grasslands around rivers and lakes were also utilised in Bangladesh, and were dominated by ekra (ikora) Erianthus ravaneae, nal "Orundo karka" (presumably either Phragmites karka or Arundo donax), ullu Saccharumcylindricum (possibly Saccharum or Imperata cylindrica), hogla Typha elephantina and hargoza Acanthus ilicifolius.
