Heartwood (HW) has a major proportion of a tree trunk, compared with its outer sapwood (SW). Researchers investigated the carbon accumulation to understand the depths of carbon sequestration in pine species in north-western Russia. They mentioned that 64% of the forests of Russian Karelia are Scots Pine which they compared across lingonberry (30% Karelia, 42%…

Climate change and soil happiness in Leningrad region
Russia has a lot of soil. Russian scientists have been investigating it for centuries and pointeered soil science through researchers such as Dokuchaev, Dokuchaeva, Glazoskaya, Glinka and others. Large soil data projects managed by land institutes e.g. GIZPROZEMs have since been updated using satellite data. Current researchers conducted an agroecological assessment. They investigated land suitable…
Forest carbon capture in the Russian carbon market
As part of Russia’s implementation of the Paris agreement, original plans and strategies suggested targets for net absorption in managed forests between 620 – 2500 mln tonnes of CO2e by 2030 (Romanovskaya, 2023). She suggests that 1.2bln tonnes CO2e by 2050 is still possible but needs restructuring of forest management systems. Also identification and validation…
Pleistocene Park creators identify 3000 yr old Siberian weather using mummified wood
Nikita and Sergey Zimov of Pleistocene Park in Sakha Republic of Russia, co-authored a study reconstructing Holocene weather conditions. This will help predict the effects of climate change in today’s Russian Arctic. Even Siberian permafrost regions have seasonal variation, especially summer and winter cycles. Mean average annual temperatures and general mean average conditions were previously…
What happens to the forest floor after Siberian wildfires?
The main tree species in the Siberian taiga are larch, Scots pine, fir, spruce, Siberian pine and birch. Lightning is more a frequent cause of wildfires in northern Siberia with anthropogenic activity causing wildfires further south, however central and eastern Siberia have been more affected overall by wildfires. They decrease soil quality (organic matter, structure,…
How is climate change affecting public health in Russia?
The researchers reviewed 1740 papers and reports which show increasing interest in the impact of climate change on public health in Russia: They were stimulated by the World Climate Change Conference held in Moscow in 2003 with the support of the United Nations and other international organizations, including WHO. The same year, the first review…
Remote sensing of Mongolian grasslands
Mongolia has 156 million hectares of grasslands, with approximately two-thirds as pasture and 1.7 million hectares for agriculture. Over half of Mongolia’s grasslands are classified as degraded, partly due to overgrazing. They wish to improve monitoring of vegetation health. With global desertification increasing alongside global temperature rise, researchers at the Botanic Garden and Research Institute…
Can Steppe trees grow fast enough to suit international climate agreements?
Researchers from Voronezh reviewed the planned timeframes for carbon absorption / emissions reduction in the Paris climate agreement, which has separate credits for projects lasting 5, 10 and 15 years with some extensions. A common method is to use reforestation together with forestry management to help absorb carbon. They noted that most Reducing Emissions from…
What is in defrosted Russian Arctic ice?
Carbon deposits in thawing permafrost include widely reported methane gases released as bubbles and present in craters across Siberia. Scientists wanted to find out more about the greenhouse emissions and what was in the defrosted ground ice including dissolved organic matter (DOM) and particulate organic matter (POM). They studied four locations across the Russian arctic…
Highway to decomposed organic matter – heavy metals in Central Siberian forests
Mining and potential toxic elements (PTE) causing soil contamination is an internationally researched issue due to the transfer and resilience of the metallic elements in the soil affecting ecosystem health. Metals move from mining dump sites either as airborne elements or through plant root structures into the soil. The researchers studied the Vilyui plain on…
