Headline: MOSCOW, July 27, 2020 - Forest fires in Russia more than doubled in size in the past week, a forestry official told TASS on Monday.
Notwithstanding the current fires in California and elsewhere, had started to follow some of the headlines/stories on Russian forest fires, and although pretty familiar with these events in Canada, Russia is a whole other story (which requires some looking at various indicators, such as forest age-class, species and fire return intervals (FRI) etc.) So, without the need for great emphasis, there is no doubt wildfires can be and are terrifying events depending on their rank and community proximity. Headlines echo these matters, people observe them first hand, and people can and have lost everything to them; the lives of loved ones, their houses and communities, and indeed there have been some fierce firestorms over the years – BC enough-times in my life; Fort Mac, Alberta destroyed, California burns - often, Australia, as people know from this past season, and Russia, as the headline above describes. Going back in time, Russia has been recorded through the news lens over many years, and it became how it was recorded that was with some interest. For instance, the above is from news agency TASS less than a month ago, and it grew in size. News sources become more interesting, described later.
In the norther hemisphere it is well into fire season, and this got me thinking on what has been seen over the decades and what headlines have said and how it is thought about on a landscape level. For instance, boreal forest fires are pretty tough to deal with - impossible really. In norther Canada they run on any given year, and there is nothing to do with them other than in the case of northern communities wherein you can try to steer these firestorms around them, if lucky. Fortunately, communities are few and far between. Russia is no different, and much bigger.
So, had never looked at wildfire stats from Russia, although observations have been made from articles, as said, over the years, so it was time to look briefly at some papers (and there are not many without more time and the resources to find them). In reality, one would need to have a complete forest inventory of species and growth compilations, and it would be useful to have orthophotos to look at historical detail, yet that is a big undertaking if you even had the data available. Some of the data found provides a little. However before exploring this, though, a scan of headlines from the western press and Russian press actually confused the issue. Both western and Russian press (like The Moscow Times) are peppered with reference to Greenpeace, the great environmental consciousness with a megaphone that echoes around the world - far from their days of saving whales and warning about war. Thus, these messages now are picked up by many aligning ‘groups’ and copied and pasted. Editors have their way with them, even Greta might have a word or two on how her childhood has been ruined because of them, yet mostly it attracts more funding to NGO's and university groups, groups who write some rather filtered findings - always with carbon worked in, which obviously is a delight for the IPCC. However, filtering further down these headlines then land in the laps of politicians who make hay with their words, as readers have all seen. These days, with fires in any country in the world, the one consistent message must be focused on carbon and people, it just has to be there as a reminder, and the arrows currently are pointing at Russia often enough when it comes to wildfires (or many other spotlights de jour). Moreover, some of the old pioneer environmentalist/biologist/ecologists/foresters have written some nifty books over the years, some good, some not so good, and most now have an agreed upon agenda. With some of the former group (most now), spending much of their discourse on the subject of carbon – it is very important to them, and they have all kinds of mathematical ways to present it. I used to pay attention to these numbers when they first came out, yet pretty much gave up on the whole idea of carbon (although it can tell a number of stories etc.) as it wanes and waxes and spews from volcanoes and other source from our yearly life on the planet. Fire weather is different, and here it comes back to a discussion between Russia and Canada and FRI’s.
Going back to recent headlines on Russian forest fires from 2020 and a few from 2019, they tend over the years to be framed to tell particular stories to western readers it seems. Here is
one example of many {
added some comments}:
From Greenpeace International August 19, 2019 (i.e. Russian Greenpeace (GP) here):
The Russian wildfires in pictures
Wondering what an area of forest burning
larger than Belgium looks like?
Greenpeace Russia has been documenting the wildfires, to show their effect, size
and catastrophic impact on all of us.
[…]
We found satellite images of fires burning
320 kilometres away {
just a short trip} so we took a small helicopter and flew over the fires in the
taiga {
note the map in the link of the taiga stretching around the northern hemisphere}. … Soon we saw a smoke column over the forest and fly into the smog. Quickly approaching furnace I must take pictures. I want to fix the disaster. I take pictures,
through my own tears.
Please have a look at the photos, because what can be observed are pretty low fire indices e.g. indices that either produce or do not produce certain characteristics. One can see these fires, with the exception of one photo – and even at that it is telling a different story, which is that they are here more or less ground fires running under the forest canopy and they are not hot rank fires; remember this because it is a constant condition in Russia’s boreal forest FRI’s. This does not suggest that there are not some high ranking fires during periods of high indices in certain forested stands, it just does not seem to be the norm.
Here are a few more of their words:
We can see the area which has already burned. The trees stand like charred matches, and the ground is covered with sores. You can see how the fire destroyed the area as it scorches the ground while trees in the distance are clouded in a viscous smoke.
Their point here seems to be that there are microsites that have high drought conditions and the trees are impacted by fire/heat on their root systems and into the canopy, while other microsites see less impact.
Every day we are feeling the
effects of climate change : from draughts (sic) in Africa, to monsoons in Southeast Asia.
The wild forests of Russia are a big part of restoring climate balance to the planet, but now they are burning —
they themselves turning into a cause of climate change.
Apparently, the speaker woke one day only to realize that forests are burning – never happened before, omg “I take pictures,
through my own tears”. Seriously.
90% of wildfires in Russia are the result of human activities
, according to official statistics
and Greenpeace’s own research . According to satellite imagery, most current Siberian and Far East wildfires started near logging sites, along roads and rivers where people have campfires.
It may look to the casual view as something ‘everybody’ needs to be writing Putin about, yet hold your horses and pens. It is here where these excited GP folks have cooked up 90% figures of human cause, which is very important to their narrative for the human angle – and it has some justification (murky as it is and as a measure of a location and not the whole of the Russian taiga). Notice how they said “most’ related to Siberia and the Far East while citing logging, roads and rivers where people have campfires (they must have seen those camp fires from satellites). Tricky how they wrote it as a reader can get lost equating Siberia and the Far East with all of Russian forests without factoring in Russia’s 11 time zones and a single transportation corridor. What are they actually talking about in terms of ‘roaded’ terrain and where they log? This is important and their language hides some of that terrain where there are no roads and no logging possible; would suggest it is a lot of terrain.
Helicopters from the Ministry of Emergencies regularly drop off firefighters in the taiga. Many courageous people are fighting this fire. But sadly, it can no longer be put out by any human means.
Firefighters are courageous, and it is darn hard work, yet crews armed with Pulaski’s against mother nature’s continual workings is not a reality for most of Russia nor Canada. Russia can only feasibly (stated in another paper below) manage what is in the protection zones, which are not that big considering the size of Russia (and it is understandable). What’s sad are these GP's collective
press officer’s in their 320 km flight to the taiga to document it all and sell it to westerners.
Climate change itself does not create fires – people do, but hotter and drier weather contributes to speeding up the spread and increasing the intensity of these and other fires.
That is their main message in red, people are the cause, hence the AGW shtick. People vs Natural ignitions is further brought up in a paper, yet it is murky also, and it must be kept in context with the transportation corridors, Siberian cities and villages (around 36 million live East of Moscow in these areas – the population of California) and the proportional representation of people spread out among the Russian terrain landscape.
Only 9% of the current fires are being tackled.
Russian authorities have made a decision not to commit to fighting these fires, because the ‘consequences do not outweigh the resources needed to fight them ’. Everyday new, vast territories are catching fire because the weather is hot and dry. Villages in Siberia and the Far East are in danger.
Russian authorities don’t fight them all (just as with most geo-locations in Canada) because it is impossible logistically to do so. Towns and villages will always have some measures, very important, and by the sounds of the FRI’s in Russia it is not as intense as in some place in Canada with different FRI’s. In Russia, firefighting measures around cities, towns and villages are not ignored either.
Note on Weather: Finding solid weather data for Russia's vast landscape is not easy, and there has been warming (and cooling) as noted in Siberian and norther permafrost bogs opening up (Canada has this also) - and possibly heating up from underneath. There is a link to Russian weather data, yet I can't read it and again, not so sure it is that extensive as a representation (temp/humility/wind), just as Canada does not have a full picture of its boreal forests, although they have many remote weather stations.
Here is how GP ends it with a link over to Bloomberg for the big picture:
We turn back, fly a few kilometre, and see a deer running beneath the helicopter. A perfectly beautiful animal in a perfectly beautiful forest.
And around it burns the world’s largest forest fire
Fires in Siberia affect the animals that live in the taiga. According
to Greenpeace experts it was the home of more more than 5500 sable, 300 bears, 2700 wild Northern deer and 1,500 elk.
Bloomberg has a number of graphics (and carbon-centric at that) and a few photos. There is no doubt it was dry that year and the indices were high, yet even the photos reviewed (colour of smoke and its spottiness) indicate that the FRI and the species composition were factors - this looks to wildfire characteristics from year to year creating natural fire breaks in the next years FRI’s. However in this 2019 article, Putin responded with a massive firefighting resources while the word watched and scolded the Russian's in the press (Bloomberg here and many others) - and these same statement are repeated even in the 2020 fire season that:
Since the beginning of the year, fires have consumed more than 13 million hectares—an area larger than Greece.
This is from
The Moscow Times and is consistent with quoting as the source, GP Russia. This year it is the size of Greece and last year it was the size of Belgium, next year it will be the size of pick your country.
Here is another example of a western MSN
headline with a lens on Russia and forest fires - the headline reads (from a few weeks ago) ‘
Wildfires in Siberia have burned down an area larger than Greece’ - yup, same talking point, and yes, that is a very large area as Greece is 131,940 sq km (or 13,194,000 ha.) - a map shows the overlay.
Looks big, and yet was that fire continuous or broken up? Does not say. Moreover, the areas burned flip flops in size from source to source - 13 million ha. to much less.
In the lead off Headline at the top of the page it cites that 44,500 ha. were impacted by a forest fire, and that is daunting to think about, and yet forests of Russia
makes up 22% of the worlds forest and covers from 30 degrees east to 180 degrees - see map.
From that
link (with a green axe to grind) it says:
The most often referred figure for Russia's total forested area is 763.5 million hectares (equal to 1.87 billion acres). There is, however, some doubt about the origin and accuracy of this figure.
{clarified further by this climate group}
Clearly, though, Russia's vast forests are a natural resource of global importance, both ecologically and economically. The forests already serve Russia and the rest of the world as a source of timber, as a symbol for wilderness and as a critical stabiliser of the global climate. According to recent estimates by the World Resource Institute, about 26% of the world's last frontier forests are in Russia. Careless exploitation of Russian forests could hold back Russia's economic renewal, permanently degrading the local environment and destabilizing the global climate.
A few choice green scare tactic words aside, as a source of timber, most of Russia is not well roaded through its eleven time zones to make it even a source, let alone viable after shipping to ports, nor does Canada at 7% of the world’s boreal forests in six time zones allow for northern road access. Nonetheless, a ha. here or there from the link, once things get burning, only mother nature ends up putting a them out.
Here is a map of the main road corridor through Russia:
As for size (and this gets really muddy with people citing sq.km. to ha., and as example (we had Greece above as a whole body), recall the Tunguska meteor took out 215,000 sq/ha. of forest and no one other than local tribes new it had happened – this kind of gives a person a lens on how big these Russian forests are. When looking at what seems like a large number (Tunguska was), what does it look like in the bigger landscape level picture. For instance, the Canadian city of Ottawa
comes in at a rounded off 2,700 sq/km. (270,000 sq/ha.) combined area, so that is larger than the area of the Tunguska's impact upon the forest, yet it shows you what that impact would do over Ottawa.
Here is a map of Ontario with Ottawa in the far south east corner. Ontario is approximately 1,076,395 km2 (or 107,639,500 ha.)
Here is all of Canada overlaid on Russia, so you can fix Ontario from that (107,639,500 ha):
There is a paper
Abstract here from 2013 that looks to Canadian (Western) vs Russian (Central) Forest fires (never mind the carbon emissions data for the IPCC folks):
Abstract
Boreal forest dynamics are largely driven by disturbance, and fire is a prevalent force of change across the boreal circumpolar region. North American and Eurasian boreal fire regimes are known to be very different but there are few quantitative comparison studies. Russian and Canadian boreal fire regimes are compared using fire weather, fire statistics, fire behaviour, and C emissions data from two large study areas. Fuel consumption, head fire intensity, and C emissions were modelled using fire weather data, fuels data and burned area polygons for all large (200+ ha) fires that occurred in the study areas during 2001–2007. Fire behaviour and C emissions of each large fire were simulated with the Canadian Fire Effects Model (CanFIRE) using fuel type and fuel load data of the burned areas, and Canadian Forest Fire Weather Index System parameters, as interpolated to the fire from the weather station network on the average active fire date. In the Russian study area located in central Siberia, there was an annual average of 1441.9 large fires per 100 M ha of forest land that burned 1.89 M ha (average large fire size = 1312 ha, mean fire return interval = 52.9 years) with an average fire intensity of 4858 kW m1. In the western Canada study area, there was an annual average of 93.7 large fires per 100 M ha of forest land that burned 0.56 M ha of forest (average large fire size = 5930 ha, mean fire return interval = 179.9 years) with an average fire intensity of 6047 kW m-1. The 2001–2007 fire size distribution and annual area burned in the Canadian study area were very similar to 1970–2009 statistics, although large fire frequency was higher and average large fire size was smaller. Similar long-term fire statistics for Russia currently do not exist for comparison. The C emissions rate (t ha-1 of burned area) was 53% higher in the Canadian study area due to higher pre-burn forest floor fuel loads and higher fuel consumption by crown fires. However, the Russian study area had much higher total C emissions (per 100 M ha of forest area) because of greater annual area burned. The Russian C emissions estimate in this study is likely conservative due to low forest floor fuel load estimates in available datasets. Fire regime differences are discussed in terms of fuel, weather, and fire ecology.
Plain Language Summary
We compared forest fire regimes for two large boreal forest areas, one in central Siberia and one in western Canada, for the period 2001-2007. North American and Eurasian boreal fire regimes are known to be different but this study provides a quantitative comparison. In Russia, most large fires (greater than 200 ha) occurred in spring and in Canada during mid-summer. In Russia, the annual area burned was more than 3 times greater than in Canada and the annual large fire frequency was more than 10 times greater. The average size of large fires in Canada was much greater: 5930 ha compared to 1312 ha in Russia. The mean fire return interval was 180 years in Canada and 53 years in Russia. The average fuel consumption and carbon emission rates within areas burned was about 50% greater in the Canadian study area, but total carbon emissions per area of forest were more than twice as high in Russia.
It is these return intervals that are important relating to fuel, and they don't seem to have very good Russian data, which Russia may have or not (harder to obtain given the size). However this gets into the higher frequencies and small sizes (Canada) which equates to more fuel on the forest floor and canopy based on longer return intervals = 179 years in Canada vs 53 years in Russia = the latter sees faster return intervals, less fuel on the forest floor and canopy (less mature forests), at least that is what it seems to be saying aside from the carbon release data that usually peppers most of the data (and its okay to mention it, not okay in how it is used).
Coming back to News for 2020, one can read from
Moscow Times (July 27, 2020) and
here for July 20, 2020):
According to Russia's agency for aerial forest fire management
Aviales, a total of 148 forest fires were
burning across 67,913 hectares of land as of midnight Monday. At the same time last week, 155 fires were
burning across 32,984 hectares of land.
Aviales is the Russian Forest Agency.
Russia's Federal Forestry Agency has
identified 10.1 million hectares of wildfires raging across the country since the start of the year. More than half of the blazes were located in forests and over 90% burned in Siberia and the Russian Far East, it said.
Russian officials
said Monday that more than 9,000 fires have destroyed 1.2 million hectares of forests.
Here is the
Siberian Times from July 27, 2020.
Russia Insider and Pravda, nothing.
Moving over to
Tass (July 27, 2020):
MOSCOW, July 27. /TASS/. Forest fires in Russia more than doubled in size in the past week, a forestry official told TASS on Monday.
"Forest fires more than doubled in size in one week. Siberia and the Far East are facing the most difficult situation," he pointed out.
According to the Aerial Forest Protection Service, a total of 148 forest fires engulfing 67,913 hectares were active in Russia as of the Monday morning. According to earlier reports, wildfires swelled from 18,000 hectares to 44,500 hectares in the Chukotka region. At the same time, the area affected by fires shrank in the Yakutia region.
This
paper 'Analysis of the Distribution of Forest Fires in Russia' is behind a paywall, and it is a bit pricey, however it provides some similar discussion, at a glance, as did the one above from Canada/Russia fire return intervals.
The problem of collecting, storing, and processing data to analyze the spatial and temporal distribution of Russian forest fires has been solved through the creation of a computer database for all forest fires within the actively protected territory of the Forest Fund (Pokrivailo et al. 1984). This includes a centralized fund of contemporary forest fire records since 1969, a reference book of Forest Fund territories and divisions, and special computer software for database processing. For each fire in the centralized fund database, information is appended on the administrative territory (geographic coordinates, forest economy, forest district, distance to the nearest populated point and transportation routes), the date and time of detection, initial attack, and extinguishment, the means of detection and suppression, forest vegetation conditions (predominant tree species, soil type, natural fire danger class), weather conditions (fire danger class, wind speeds, precipitation), the fire cause and type of fire (ground, surface, crown). For this analysis of the spatial and temporal distribution of fires, more than 2,500 fires from this database, along with fire statistics since 1947, were used.
This may offer a good background based on the data it seems to say it collected.
Now this is from the US Forest Service 'Fire in Siberian Boreal Forests — Implications for GlobalClimate and Air Quality' (
Pdf.) with emphasis on carbon, yet it was worth a read because it aids in some of the FRI language and also species composition data. Here is a bit of it:
Extent of Fire in Russia’s Boreal ForestsFire is one of nature’s primary carbon-cycling mechanisms. It is a critical disturbance factor in Russia’s boreal forests, where many fire scars are visible across the landscape and vegetation patterns are often dominated by evidence of past fire history {return intervals}. During the summer fire season, one can hardly fly across central Siberia without observing smoke plumes from the often numerous wildfires. Although data are somewhat sparse, dendrochronological studies have estimated typical fire return intervals of 25 to 50 years for Pinus sylvestris forest types in central Siberia (Furyaev 1996,Swetnam 1996). Longer fire return intervals (90-130 years) appear more typical for forests dominated by Larix species (Furyaev 1996, Valendik [In press]) and by Abies siberica and Picea obovata. Fire return intervals also decrease from north to south (they may be as short as 10 years on some sites), and are longer on the most well-watered sites along rivers or in areas where forest stands are isolated by wet bogs (FIRESCAN 1997). As a reflection of the difference in dominance and in fire return intervals of the various forest types, about 70 percent of the fires in Russia occur in light coniferous pine and larch-dominated stands (Pinus sylvestris or Larix), and only about 15 percent in dark coniferous boreal forest (primarily Abies, Picea; basedon Korovin 1996), although the latter cover about 31 percent of the boreal forest area (Tchebakova and others 1994). About 80 percent of the area typically burns in surface fires (Furyaev 1996, Korovin 1996), but patchy crown fires are common, and in severe fire seasons, crown fires may dominate. The Russian Forest Service (Nyejluktov1994) reports a range of 12,000 to 34,000 wildfires a year in Russia during the period from 1974-1993, with a long-term average of about 17,000 fires per year. Most of these fires occur in a 4-month fire season that extends from May through August (fig.1)
Notice it says "about 80 percent of the area typically burns in surface fires" unless (probably like this year 2020) it goes to crown fires. When looking at photos and considering the fire return intervals, the majority seem to creep under the canopy with less fuel as part of a quicker FRI. Whereas in the Canadian study the returns were well spread out "179 years in Canada"(in that sense they burn hot and are often full crown fires as they are loaded with fuel from the longer interval periods of growth. Factoring species, in Russia larch was dominating.
Going back to human cause for fires as discussed above by GP, it is reasonable to suggest that along the road corridors with cities, towns, villages, there will be network roads for harvesting resources and fire may start as a result of people; their numbers seem high. Here is what they say in this study (much conjecture):
Human Influences on Fire Regimes Statistics over a recent 3-year period for Russia show that more than 65 percent of wildfires are human-caused, and about 17 percent are confirmed to be caused by lightning (fig. 3). Newer information, however, suggests that the importance of lightning ignitions may have been underestimated. Of the 17 percent of fires where cause is unknown, evidence from recently-installed lightning detection systems suggests that many of these may be lightning fires. And the importance of lightning as an ignition source varies greatly geographically (table 2), with the highest percent of lightning ignitions in relatively unpopulated areas such as the Krasnoyarsk and Yakutia regions.
Yes, lightning detection has advanced and records well what happens. However these guys double back to say that it is still largely human cause, yet if the same data is taken from Canada, lightning rules in norther areas. Again, there is so much uninhabited areas of Russia that lightning must be underrated also. Have a look at this
map for habitation densities and one can get a picture of what it looks like in Russia (and Canada for that matter). Much of Russia is < 2 people per sq.km. (and 2 10 per sq.km.).
Whatever the case, 2020 has had some big fires, and these fires have a FRI cycle that can, from time to time, encompass large areas as stated, yet not necessarily a continuous large area burned as the headlines demand. As ecosystems go, whether in Canada or Russia, wildfire play an important role at regeneration, removing fuel, opening up animal habitat, and is a constant for forest health by reducing pathology (blights to insect buildups).
The most interesting thing about this has been to see how (even with some Russian news outlets) there is such a reliance upon Russia Greenpeace data (this was surprising) - which looks sketchy, along with the overall lack of forest data with much speculation. Of course the mass focus is all on carbon, and people as a constant theme, which fits with their anti-Russian government talking points echoed down the line in most, if not all, western press headlines and text body.
This just scratches the surface and it would be interesting to look at real Russian data.
