Excerpt from The Economic Value of Our Native Birds: Discussed by Orders and Families; Order XIII, Macrochires, Goatsuckers, Swifts, Humming-Birds, Etc.; Family 20, Caprimulgidae Nighthawks, Whippoorwills, Etc.; Family 21, Micropodidae, the Swifts; Family 22, Trochilidae; The Humming-Birds The work of this office has been so pressing, and growing to such an extent, that it has not been possible to issue the Quarterly Bulle tins as promptly as we have desired, but with a greatly increased force we hope to be able to overcome this difficulty by the next issue. As the value of our investigations depends to a great extent upon the co-operation given by the citizens in various parts of the State, we request all persons who can do so to send us specimens of insects and reptiles for our studies of these creatures in Pennsylvania, and also specimens of such birds, or at least the bird-stomachs with their contents, as they may be able to procure by legal means. Birds are often found dead, and we shall be glad to receive these to make a study of the causes of their death, as well as their food and such other features as will be of value to scientists and other persons. Large specimens may be sent by express, at our expense, and small specimens may be sent by mail, and postage will be re funded. In all cases it is very important that specimens should be so packed in firm boxes or cans that they will not be crushed in transit. As we have no way of keeping specimens alive, and as we especially wish to study their stomach contents, it is quite desirable that they should be killed as soon as they are collected or before shipping. We do not have funds for purchasing specimens at the present time, but shall reciprocate all favors whenever possible. Address all packages and communications to Prof. H. A.

Economic Valuation of Ecosystem Services Provided by Forest Ecosystems in Sri Lanka

A Study Based on 2010 Forest Cover Classification and the TEEB Database

Ecosystem service valuation is becoming popular among the economists, ecologists, scientists and policy makers. As a result, various research, publications and programs have arisen and content of literature is developed rapidly. Even though this field of study is developing rapidly, Sri Lankan ecosystems have not yet been valued or evaluated yet in terms of economic returns. Hence, the main purpose of this study is to calculate and define economic value for each forest polygon of 2010 forest cover data base by using the value transferring approach. This data base will be an effective tool to have a fair cost-benefits analyses of development projects which are most likely planned to be implemented on forested landscapes. The value transferring approach was selected for this study considering the free availability of data and expensive and time-consuming nature of primary valuation approaches. This study includes two main analyses: an estimation of total economic value of all ecosystem services provided by forest ecosystems of Sri Lanka and an estimation of economic value of water services provided by the forest ecosystems within the Mahaweli River basin which is known as largest and longest river basin of Sri Lanka. For the first analysis, required reference values of ecosystems services were found from the equivalent biomes of TEEB database. These reference data were processed at three levels and standardized to 2019 US dollar values by following a standard procedure. These processed results regarding water services were used for the second analysis and the watershed boundaries, sub-watershed boundaries, stream network, pour points were created using Arc Map 10.8.1. According to the results of first analysis, the total annual economic value of all considered ecosystem services range from US $ 3.472 billion to US $ 138.818 billion and the estimation can be averaged at US $ 34.5 billion. Results further confirmed that mangrove forests are important and ecologically valuable by reaching to the highest per unit area annual economic value being estimated at US $ 42856 per hectare per year. The water service analysis revealed that the economic value of water services provided by all forest ecosystems within the Mahaweli river basin is US $ 67.9 million. Analysis further indicated that, US $ 11,247,073 worth of water services are produced by the 78,429 ha of forest lands within the Parakrama Samoodraya sub-watershed annually. These results of both analyses are important in future conservation and management decisions making, especially regarding identifying restoration and enrichment priorities, and as a progress monitoring tool.
