East Kalimantan Ecoregional Assessment: Chapter 2 – Target Ecological Systems The illustration below portrays the respective viability rankings for the individual segments of major rivers in stratigraphic unit 1. Red reflects a Poor or Very Poor viability rank – depending on the density of the color. Green shows those areas still in Good to Very Good condition. Portfolio Design The goal for each river system was 100% of prime catchment areas (captured in appropriate target rainforest ecological system types referred to previously), 100% of the vegetation in good to moderate condition bordering the length of the river to a width of 500 meters on each side of the river from catchment area to terminal delta mangroves, and 75% of the mangrove system at the mouth of each river (also captured in Mangrove ecological system referred to in previous chapters). 57
East Kalimantan Ecoregional Assessment: Chapter 3 – Portfolio Results & Assessment Summary Chapter 3: Portfolio Results & Assessment Summary A. Number of sites recommended within the Portfolio There are a total of 33 conservation sites proposed within the East Kalimantan Portfolio. The sites range in size from a small 1,360 hectares at the combined Pulau Derawan three-island site, to the largest being the Kayan-Mentarang National Park site at 1.84 million hectares. The most complex site in terms of number of conservation targets and integration of aquatic and terrestrial targets is the Rawa Sesayap site in the Stratigraphic Unit 1. Refer to the Portfolio Map opposite for reference. A detailed description of each of the proposed sites is included in Appendix I of this report. B. Total Area encompassed within the Portfolio Out of a total of approximately 20 million hectares contained within the ecoregional assessment area, 17,408,103 hectares remain forested – the rest has been permanently denuded, developed or otherwise converted to non-forest status. The Portfolio consists of 6,515,145 hectares or 37.43% of the forested regions of East Kalimantan, or 32.6% of the Province total area. C. Area of the Portfolio within “already protected areas” While it appears that we have captured many of the “already protected areas” within our proposed portfolio of sites, it must be recognized that their official designation as National Parks (Taman Nasional), Protected Forests (Taman Wisata) or Protected Areas (Cagar Alam) does not reflect the reality of a general lack of meaningful protection of their ecological integrity. That said, it is also recognized that there will be a higher degree of interest among current and future legislators and Provincial government officials to step up protection of already designated areas rather than trying to convince them to invest limited resources or political capital to establish new conservation areas. The equally nebulous designation of Restricted Forest Area (Hutan Lindung) is a category of protection technically based upon degree of slope being at or more than 45%, but it is controlled at the individual Kabupaten level of government, and is changed to suit the whims of the Bupati or District Mayors. Even though supposedly off-limits to commercial logging interests, the demand for illegal logs to supply an overabundance of pulp and plywood mills makes this designation suspect as well. It does at least provide some guidance for the legal commercial loggers to set aside these areas within their HPH concessions and provides conservation groups like TNC the inroad for discussing greater, more meaningful set-asides within these leased areas. Therefore, we are careful to propose in this Ecoregional Assessment, not the creation of new National Parks or even new Protected Areas, rather, the enhanced management of the recommended Portfolio Sites for the benefit of the target species and system types as well as their continuing regulated resource use and extraction. 2
