“…Anaerobic storage below the ground and water table is a secure way to protect stumps against decay agents in Finnish cutaway peatlands. When developing anaerobic storage systems for sawlogs, where timber is bundled within a double layer of polyethylene tarps, it has been found that the oxygen content must always remain below a 2% threshold to guarantee optimal conservation (Mahler et al 1998, Riguelle et al 2017. Today, stationary wooden structures associated Fig.…”

Stump harvesting for energy has decreased in Finland, and many heat and power plants no longer accept stumps in their fuel portfolio due to fuel quality problems. However Finland is a forested country, and land clearing stumps need to be extracted, e.g. in infrastructure construction projects. If stumps cannot be used for energy production, they are dumped in landfills, where they start to decay and release CO2 into the atmosphere. One option to avoid CO2 emissions would be the burying of stumps underground so that the decaying process of wood would be inhibited in anaerobic conditions. The aim of this study was to define the carbon sequestration potential of stump burying logistics and calculate their CO2-eq emissions to compare them with the emissions of decaying stumps in piles. The analysis was performed as a spreadsheet-based system analysis at a worksite level as a function of time and size of extracted stumps. As a result of the analysis, the emission effiency of the logistics chain based on stumps stored below the ground was good. The net carbon stock varied between 743.7 and 775.0 kg CO2-eq/m3 as a function of stump diameter, when the emissions of the stump burying logistics chain were 49.0 and 17.7 kg CO2-eq/m3 respectively. In the case of a Finnish municipality with an annual accumulation of 1000 m3 of land clearing stumps, the carbon sequestration potential of stumps buried underground is equivalent to the emissions of between 280,000 and 290,000 liters of diesel fuel consumption, depending on the diameter of the extracted stumps and the diesel fuel emission factors for different engine and diesel fuel types.

To prevent the illegal trade in wild species, stock management is critical given stocks function as a buffer to supply chains during lean periods or as a mechanism for market speculation. The Madagascar government with backing by the World Bank recently promoted the sale of confiscated rosewood to reach a zero‐stocks situation. To better assess options, we contrast the risks and rewards of four stock management options. Stock destruction broadcasts a potent conservation message, but provides little economic benefit. National trade can be beneficial to local socioeconomic development goals, but can lead to laundering of illegal products. International trade is fraught with risks related to illegal trade and is perceived to achieve the least related to forest and socioeconomic indicators. Lastly, banking stocks act to postpone decisions. No management option ensures a sustainable solution, but critical analyses allow better insight to the strengths and weaknesses of the available approaches.

“…Logs can also be stored in sealed containers under anaerobic conditions, which results in minimal deterioration. However as this is a very expensive method, it is rarely undertaken (Riguelle et al 2017). The value of rosewood declines in proportion to the length of time that it has been placed in storage.…”

Stocks and stockpiles of CITES (the Convention on International Trade in Endangered Species of wild fauna and flora) listed wildlife, including animal and plant-derived products, remain a complex, unresolved issue. The biggest challenges lie in the prevention of further illegal sourcing of—and trade in—products originating from wild populations of threatened species. Stocks can function as a buffer during lean periods or as a mechanism used for speculation. As we outline in this paper, the current situation in Madagascar precludes non-detriment findings intended to enable sustainable use of standing rosewood populations. Backed by the World Bank, the previous Malagasy government was in the process of promoting the sale of massive stocks and stockpiles of confiscated precious woods in order to reach a zero stocks goal, this being ostensibly to halt the illegal sourcing and trafficking of rosewood. We propose and analyse four potential options for stocks management by presenting a framework linking forest management with socio-economic objectives and comparative risks. Destruction (burning) of the known stocks would send out a strong conservation message and has the strongest chance of halting further sourcing, which happens mostly in protected areas and is therefore illegal. National trade is the option in which a precious timber sector would process the woods in stocks. This option is the most beneficial for development. Opening the stocks for exportation through international trade achieves the smallest number of objectives in relation to both forests and socio-economic indicators, but comes with the highest risks in terms of curbing further illegal logging. Banking represents a fourth option, which essentially postpones any decision related to stocks management by storing the stocks for extended periods. None of the four management options is able to ensure a sustainable solution that can resolve the issues surrounding the precious timber stocks. The approaches put forward are either just ‘more good’, or ‘less good’. If a country is seriously interested in conserving its biodiversity, any government has to ensure that no other sectorial changes will counteract, or potentially undermine, the efforts to protect the environment. Stocks management will be on agenda at the upcoming COP18 in Geneva, 17–28 August 2019.
