Avian Biodiversity at Malagos Watershed Baguio District, Davao City Geonyzl L. Alviola Dr. Bernadette del Rosario Melodie Claire Waay Nicefora Tubera Zeny B. Egut
<ul><li>Malagos Watershed is one of the 8 watersheds supporting the water supply of Davao City and protected by the government. </li></ul><ul><li>Since 1990 the forest fragment was deforested because of the loggers and some part of the land were converted to agriculture. </li></ul>
But in early 1990 Davao City Water District (DCWD) together with other environmental organization the establish a reforestation project to restore the degraded forest fragment
Even it was rehabilitated most of the edge of the forest fragment were own by private sectors and converted to agriculture use.
Why the birds? <ul><li>The bird species is one of the known biological indicators in assessing and provide crucial information on the ecosystem. </li></ul><ul><li>Each species of bird has its own habitat requirement(Steadman,1997 and Crosby,1998). </li></ul>
In Malagos Watershed.. <ul><li>There were four avian survey had been conducted in the protected area in a short period of time. </li></ul><ul><li>Some species of birds were not yet accounted because of migration behavior. </li></ul><ul><li>Regular avian survey within the vicinity of the watershed would provide an information or an update on listing of birds to serve as database to improve the wildlife management in the protected area. </li></ul>
Statement of the Problem: <ul><li>General: This study aims to document bird species in Malagos Watershed. </li></ul><ul><li>Specific: </li></ul><ul><li>Identify and classify the species of birds within the protected area. </li></ul><ul><li>Provide a bird species inventory observe in one year as baseline data for monitoring with in the protected area. </li></ul><ul><li>Compare the taxonomic listing of birds done with the previous researches. </li></ul><ul><li>Determine the distribution of birds within the protected area. </li></ul>
Significance of the Study . <ul><li>The inventory of birds at Malagos Watershed would be useful to the Philippine Eagle Foundation and Government organizations like Davao City Water District to determine if their conservation or preservation programs show a positive or negative result. </li></ul><ul><li>To the community would also be aware of the present condition of the area. </li></ul>
Scope and Limitation: <ul><li>The study will focus on the identification and assessment of avian species within the Malagos watershed within 11 months. </li></ul><ul><li>The collection will be twice a week in a month every 1st week and 3rd week using the mist netting and point count method. </li></ul><ul><li>Observation will start from 0500 hr to 1700 hr for mist netting and 0600 to 1700 hr for point count in a fair weather condition. </li></ul>
Methodology <ul><li>The area will be divided based on habitat type for the survey. </li></ul><ul><li>two methods used in the survey to insure to capture also the ground and shy birds. </li></ul>
<ul><li>Mist nest will be set in the point count area. </li></ul><ul><li>Birds capture by mist nets will be marked and photographed for documentation. </li></ul>
<ul><li>To measure the diversity of species in the area Species Richness (S), Simpson Index (D), Shanon-Weiner Index will be used. </li></ul>
