Forests provide a number of ecosystem services including biodiversity, which could be added multiple benefits to the climate change mitigation potential arising from implementing REDD+. However, there have also been concerns that harms to ecosystems could ensue from its implementation. Monitoring would be one way to support and promote benefits and avoid harms to the ecosystem. However, monitoring changes in carbon stocks for anthropogenic forest-related greenhouse gas emissions and removals estimation will impose considerable demands on REDD+ countries, and additional monitoring would increase the cost and burden on countries.  This paper investigates the relationship and potential synergies between monitoring systems for carbon stock changes and multiple benefits from REDD+. Monitoring multiple benefits, such as biodiversity and ecosystem services, has usually been undertaken by selecting a set of indicators. A good framework of indicators provides more robust way to preserve benefits. However, identifying measurable indicators, setting baselines and determining the frequency of measurements for other benefits of REDD+ is challenging and these do not necessarily match those required for carbon.
