(no Russian authors) https://rdcu.be/ebSxH ..Forest-height estimates were then subtracted from the predicted site index to estimate height-age growth potential across the region. Russia, which comprised 73% of the forest change domain, had strong departures from model expectation of 2.4–4.8 ± 3.8 m for the 75th and 90th percentiles. Combining satellite observations revealed a large young forest growth sink…
Heartwood and carbon in NW Russian pine trees
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…
Decarbonising economies – Russia, China, Brazil, Germany, Japan, India
All six countries have strategies towards achieving carbon neutrality. The researchers report that they have 44% of global population, 39.2% global GDP, 44.8% primary energy consumption and 49% global CO2 emissions. They note that different views on economic development and energy transition affect an overall international climate outlook from agreements such as Paris 2015. They…
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…
Polar bear poo and human waste
Affected by ice free seas, polar bears are increasingly visiting human villages and adding human waste to their diet. So what are Russian Arctic bears eating? Researchers decided to analyse bear poo to measure natural vs human waste sources of food. Arctic sea ice melt has left polar bears unable to feed on their natural…
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,…
Carbon update from the Ladoga polygon
The Ladoga polygon is part of a network of carbon monitoring sites, with Ladoga providing data for this north-west region of Russia. It stores large volumes of carbon in soils, approx 208 tC/ha which is the largest volume outside of permafrost affected soil. The region has not had any significant agricultural activity for over 40…
