Ecosystem Accounts for Southern Palawan 2WAVES © 2016 ECOSYSTEM-defined • Ecosystems are a dynamic complex of plant, animal and micro- organism communities and their non-living environment interacting as a functional unit - Convention on Biological Diversity (2003). Article 2. Use of Terms • Ecosystem may be identified at different spatial scales and are commonly nested and overlapping. Consequently, for accounting purposes, ecosystem assets are defined through the delineation of specific and mutually exclusive spatial areas

- The Land Cover account points to the major deforestation that took place in the period 2003 – 2010, when the closed forest cover decreased from some 130,000 ha to around 28,000 ha. The loss of closed forest cover seems to have halted in the period 2010-2014, when there was an increase from 28,000 to 33,000 ha. The Land cover account also show the large growth in plantation crops, in particular coconut and oil palm plantations.
- Nasa inyong kaliwa makikita ang konsentrasyon ng sediments sa buong Pulot Watershed, ang nasa kanan naman ay ang mga lugar na nasa taas ng dam na pinang gagalingan ng sediments…. Ating makikita yung mga may asul na matingkad ay may mataas na konsentrasyon ng sediments eto ang anim na sub watershed na nakaa contribute ng sediments sa dam
- Ang kagubatan ng Pulot Watershed ay napaka halaga para masigurado ang tuloy tuloy na daloy ng patubig sa ating mga palayan.
