  • WETLANDS in PAKISTAN: WHAT IS HAPPENING to THEM? By: Abdul Aleem Chaudhry Ph.D
    World Environment Day – June 2010 49 WETLANDS IN PAKISTAN: WHAT IS HAPPENING TO THEM? By: Abdul Aleem Chaudhry Ph.D. Director General Wildlife and Parks Punjab (Retired) Abstract Pakistan, despite having an arid climate, supports over 780,000 ha of wetlands covering 9.7% of the total land area, with 225 nationally significant wetlands, of which 19 have been recognised as Ramsar sites of global significance. Wetland types represent the passage of the Indus River from the glaciers and high alpine lakes, through riverine and freshwater lakes to the coastal wetlands of the Indus Delta. These wetlands provide often unrecognised benefits and services, such as provisioning - food and fibre production - regulating services such as water balance, groundwater recharge, flood mitigation and storm protection; cultural and social functions such as sacred and religious importance; providing recreation and tourism opportunities; and supporting functions such as soil formation and sediment retention. Main threats to wetlands include shortages of water to maintain the wetlands, poor water quality from increasing pollution, change in land use, encroachment and over- exploitation of natural resources, such as fish and wildlife. Most often the over- exploitation is driven by the lack of alternative livelihoods so that poor communities may have no option. The underlying causes of these direct threats are related to the perception that wetland natural resources are part of an open- access system. Management of the natural resources, if it exists at all, is usually ineffective and penalties for illegal or inappropriate resource-use are often not significant enough to be prohibitive. These inappropriate practices generally stem from policy shortcomings, legal gaps and inconsistencies, failure to enforce regulations, and institutional overlap of responsibilities for management of wetlands and lack of coordination.

    © Copyright, Princeton University Press. No part of this book may be 4 BIRDS OF INDIAdistributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. INTRODUCTION Birds of the Indian subcontinent an overview by Carol and Tim Inskipp The Indian subcontinent has a great wealth of birds, making it a paradise for the birdwatcher. The classic Handbook of the Birds of India and Pakistan by Salim Ali and S Dillon Ripley, which covers the whole region and was first published in 1968-1975, lists over 1,200 species. With additional recording and following the more up-to-date nomenclature in the Howard and Moore Complete Checklist of Birds of the World edited by E. C. Dickinson (2003) the current species total for the subcontinent stands at 1,375 species – 13 per cent of the world’s birds. A further relevant reference is Birds of South Asia: the Ripley Guide by Pamela Rasmussen and John Anderton, which has adopted much narrower species Dr. Salim Ali limits and, consequently, the latest edition (2012) recognises 1451 species in the region. Note that less than 800 species are found in all of North America. The Indian subcontinent is species-rich partly because of its wide altitudinal range extending from sea level up to the summit of the Himalayas, the world’s highest mountains. Another reason is the region’s highly varied climate and associated diverse vegetation. The extremes range from the almost rainless Great Indian or Thar Desert, where temperatures reach over 55°C, to the wet evergreen forests of the Assam Hills where 1,300 cm of rain a year have bee recorded at Cherrapunji – one of the wettest places on Earth, and the Arctic conditions of the Himalayan peaks where only alpine flowers and cushion plants flourish at over 4,900 m.

It is the only significant offshore island along the north coast of the Arabian Sea, and as such maintains the genetic and ecological diversity of the area. The endangered Green turtle (Chelonia mydas) and possibly the Hawksbill turtle (Eretmochelys imbracata) nest on the beach at the foot of cliffs, and it is a very important area for endemic reptiles such as the viper Echis carinatus astoli. The island is said to have an aura of mystery and is venerated by Hindus; there are architectural remains of an ancient temple to the Hindu goddess Kali Devi, as well as a prayer yard constructed for a Muslim saint associated with oceans. It serves as a base for fishermen between September and May, but is unfrequented during the period of rough seas and high tides. Feral cats originally introduced by fishermen to control the endemic rodent population pose an increasing threat to birds' nesting and breeding sites. Reprint of the RIS. Ramsar site no. 1063.

Abstract The present study on conservational status of Marsh Crocodiles, Crocodylus palustris has been carried out from the Haleji Lake Wildlife Sanctuary (HLWS) Thatta, Sindh, Pakistan. This research study was carried out during the year of 2006-09. We observed and recorded the total numbers of C. palustris two hundred sixty nine (269) in the HLWLS, among them one hundred seventy nine (179) were adult crocodiles, thirty seven (37) were juveniles and fifty three (53) were hatchlings. Various instances of human-crocodile conflicts were observed including 7 injured and three human causalities. Innumerable types of threats to Crocodiles were also noticed including habitat loss, alteration and soil erosion and mortality due to fishing practices. We were determined that the Crocodile population is increasing in HLWS due to strong conservational strategies and management. The present study suggests that further research to propose strategies to conserve this vulnerable species. *Corresponding Author: Muhammad Saleem Chang [email protected] 64 | Chang et al.
