A Forest Estate in the Heart of Borneo
The PT Karya Delta Permai (KDP) concession lies in Murung Raya Regency, Central Kalimantan — part of the Heart of Borneo conservation area at the headwaters of the Barito River, where the Müller-Schwaner mountains rise across the northern landscape.
The 85,950 ha forest estate was established under Ministry of Environment & Forestry Decree No. SK.89/MENLHK/SETJEN/HPL.0/1/2022, spanning production, limited production, conversion, protection, and sanctuary forest functions (APL, HP, HPT, HPK, HL, KSA/KPA).
The concession sits on mineral soil ecosystems dominated by dystropepts and tropudults, with hill-dominated topography characteristic of upper Murung Raya.
KALYRA's mitigation actions across the concession combine reforestation, prevention of unplanned deforestation, and Reduced Impact Logging–Carbon (RIL-C) — a 25-year programme designed to make conservation economically viable for the region.

Location Overview
Geographically located at 114°03'00"–114°30'00" East and 0°11'00"–0°33'00" South, the area is dominated by hilly topography within the Barito River basin. The Müller-Schwaner mountains in northern Murung Raya form the headwaters of the Barito, placing the concession inside the world-renowned Heart of Borneo conservation landscape.
Emission Reductions Over 25 yrs of Crediting
Across the 25-year crediting period, the KDP programme is estimated to deliver a total greenhouse gas emission reduction of 22,186,994.08 tCO2e — 19,660,823.06 tCO2e from reforestation activities and 2,526,171.02 tCO2e from preventing unplanned deforestation, with zero leakage emissions.
RIL-C harvesting operations delivered an estimated emission reduction of 57,537.43 tCO2e in 2023, the first full year of implementation.

A Refuge for Borneo's Rare & Threatened Species
Exploration and inventory surveys recorded 341 plant species dominated by Dipterocarpaceae, alongside 43 understory species — and a fauna assemblage of 18 mammal, 69 avifauna, and 52 reptile species.
The concession holds High Conservation Values 1, 2, and 3: areas of significant biodiversity, large landscape-level ecological processes, and rare or threatened ecosystems — including the rare Pendreh (PDH) ecoregion class found across the Beriwit, Luang, Mantalat, Maput, Pakalunai, Pendreh, Tandur, and Tewai Baru ecoregions.

Survey teams also recorded Nyctixalus pictus frogs, Anthracoceros malayanus hornbills, sun bear tracks, and Hebius flavifrons snakes — evidence of a functioning forest ecosystem. Local communities were also found hunting within the project area, including primates caught with snares, underscoring the need for continued anti-poaching patrols.

Known Threats & Mitigation
Social studies identified illegal logging and illegal mining practices in villages across the concession — threats the project actively mitigates through protection patrols and alternative livelihoods.
Transparent Risks, Clear Mitigation
Risk analysis is included so the project owner fully considers and articulates project risks in a clear and transparent way — together with the proposed mitigations and their timing.
Lack of secure continuing financial resources until the project reaches cumulative break-even cash flow.
