Long-Lasting Battles in the Northern Forests

Forest fire control officials have been already working hard to win the battles against forest fires in the North, but it’s the war that is hard to win without proportionate and appropriate policy to address their root causes

Pichit Piyachot has won the latest battle, but he cannot totally say that he has won this war; fighting forest fires in the North.

Yesterday, the chief of Mae Ping Forest Fire Control Station reported back to the Department of National Parks, Wildlife, and Plant Conservation (DNP) in Bangkok that his team including the special fire control sub-units of Suea Fai (A tiger slapping fires) sent from Phitsanulok and Chumporn provinces managed to douse forest fires, which had burned over 150 rai of the Mae Ping National Park, which spans over parts of Chiang Mai, Lam Phun, and Tak provinces.

In fact, the chief’s team last week managed to protect the prime watershed inside the national park, which narrowly survived the fires that had burned its vast and iconic grass field locally known as Thung Kik.

The chief has won the battles, but not yet the war against the fires. The fact is the fires were started from uncontrolled “human activities” and that the fuels in the park were almost gone as they were almost burned down. According to Fah Foon Facebook Page, which is run by an independent aero engineering expert to dedicate its space for PM2.5 analyses, the scope of over 400 square kilometres or over 250,000 rai of the national park was burned by forest fires since early last month, and if assuming that up to 60% of the area was seriously burned down, it’s already the size of the burn scars that occurred over the last two years, or around 150,000 rai!

Since the “fire season” started in the region, which has seriously been suffering from forest fires and PM2.5 in recent years, officials concerned have put efforts to prevent the forest fires by undertaking pre-season fire management starting around mid-January. But as analysed by the page, which has been following up on the situation daily based on reliable satellite data sources including GISTDA, the poor regulation of the state fire management including pre-season forest burning and forest firebreaks rather triggered uncontrolled fires by local people, who rushed to imitate the officials’ action for their own purposes; clearing the forests for forest product collection, wildlife hunting, and others (Some even said these included the revenge and opposing expressions against the state fire control measures!).

The Pollution Control Department (PCD) in mid-February started to report the impacts of the uncontrolled forest fires that by then the PM2.5 haze was polluting the region to the level that it had affected people’s health. On Feb 16, for instance, the PM2.5 concentration level in the region shot up to 192 µg/m³, far beyond the safety limit set at 50 µg/m³.

According to Dr. Pinsak Suraswadi, the PCD’s Director-General, the northern region had actually started to feel the impact of PM2.5 since late January, and since, the dust concentration level had been increasing over time because of increasing forest fires in the region.

Based on the department’s data analysis, 18,988 hotspots occurred over one and a half months between Jan 1 to Feb 15. This increased from the number of hotspots recorded during the same period of time last year up to 118% (8,698 recorded last year). The number of days with dust levels beyond the limit also increased by 72% compared to last year, or 31 compared to 18 days. And the 24-hour dust concentration level was also 67% higher, or 45 µg/m³ compared to 27 µg/m³.

Over 70% of those hotspots were forest fires; half of these were found in protected forest areas and the other half in forest reserves, the department confirmed.

The DNP realised the situation too. Under the new directive of its acting Director General Athapol Charoenshunsa, 455 fire control officers as well as 225 Suea Fai officers who are specially trained to control forest fires in difficult situations were called in around the middle of last month to help suppress the fires in the region, of which at least 15 protected areas including Mae Ping in 17 northern provinces were the forests with burn scars. Mae Ping is the second most severely burned protected area in this group.

As a chief of the forest control station in the area, Mr. Pichit realised well how tough it was to suppress those fires. Day in and day out since early February, they have been teaming up with Suea Fai and local networks to extinguish the fires against almost inaccessible landscapes. The chief himself has lost five men of his to the fires over the past years, and he was close to tears when recalling those fallen officers and had to stop short of saying more about them.

In some recent battles, the chief has actually lost. In one event, they mobilised the team to suppress the fires that were burning one side of Thung Kik to the point that his men had to raise the white flag. “They are coming fast and we cannot blow these dried leaves up to block them. We need to retreat to the next stream and there we will try to push them back again,” said one of his men to the chief, who by then had to accept his subordinate’s recommendation for the sake of their safety with a facial expression of disappointment.

As for the DNP, it has declared closure of 79 protected areas in an attempt to suppress “human activities” that are closely linked to locals’ livelihoods and economy amid a growing call for proportionate and appropriate policy to help address these deep-rooted causes of the fires, or they will never win this war.

Mar 1, 2023: An aerial photograph taken by the Mae Ping Forest Fire Control Station shows smoke choking out of the forest fires on the ground, which helps locate the target areas. The critical groundwork is usually conducted ahead of the forest fire control work on the ground. A helicopter is usually sent in to survey and splash the water on the target areas before the team on the ground will get to the target areas to douse the fires. They need to work in harmony and fast as the water will quickly dry up and the airborne operation will become helpless. Most of the Mae Ping National Park is deciduous forest, of which trees will shed leaves to conserve water in the dry season, thus leaving tons of forest fuels in the areas.

Pre-season forest fire management including pre-season forest fuel burning and forest firebreaks, if undertaken properly, can help control forest fires. It’s widely accepted that wildfires are useful for forest growth, but anything beyond the natural cycle is now disrupting the natural process and has caused the forest to lose its balance.

Under the new directive of DNP Acting Director General Athapol Charoenshunsa, 455 fire control officers as well as 225 Suea Fai officers who are specially trained to control forest fires were called in around the middle of last month to help suppress the fires in 17 northern provinces, of which at least 15 protected areas including Mae Ping were the forests with burn scars. Mae Ping is the second most severely burned protected area in this group. Seen in the photo are Suea Fai and Mae Ping officers helping one another douse the fires in the Yang Wee area. It took them three days to douse the fires, just to learn that the new forest fires started again somewhere near the next day.

As told by the officer, if forest fires are sparked, they will then start to spread out quickly over the fuels on the ground. So, getting to the fires quickly is the key to success in extinguishing them.

Suea Fai and Mae Ping officers fight the fires hard with leaf blowers in their hands. Suea Fai, in particular, is a well-trained unit with fire extinguishing techniques, especially in rugged and terrain locations and they can work in difficult situations for up to three days without further support. The unit was set up over 20 years ago and up until present there are over 200 of them deployed at the special forest fire control operation centres nationwide.

The most challenge in forest fire control is the rugged and terrain locations. On rocky landscapes, the fires seem to have extinguished, but the rocks are still hot and hardly stepped over. And underneath them, the fires could return. In grass fields, the fires spread fast and grow over and it’s hard to project their directions. Often, forest fire control officers have to retreat and let the fires claim such areas because it’s too dangerous to take a risk.

It’s dawn and the sun doesn’t rise past the canopies, but Suea Fai officers are called through their radio communications. The temperature is chilling with 14 degrees Celsius recorded, but the officer said it can be heated up quickly by forest fires. Often, they encounter such rapid changes in temperature. Suea Fai officers are well-trained to handle the situation and are on standby for every situation, day and night.

The Mae Ping forest fire control officer briefs Suea Fai about the landscapes and the fire directions by drawing what he knows on the ground before Suea Fai officers get to the fires and douse them. Planning and assessing the situation together with their shared knowledge and experiences are the other keys to success in extinguishing forest fires.

The burned forest areas are like injured creatures as they can pose harm again, said the officers. After the fires have burned the areas, the officers discuss and re-plan to overcome the fires that still spread out. Despite some disappointment in the fact that they have lost in the battle, the officers re-assess the situation and project the fire directions again. Various techniques are brought up in their discussion. They read the burned track and consider setting a fire on the other side to help break the spreading fires or make use of the stream and the track of fuels alongside to break the fires. Knowledge and experiences help guide their assessment of the situation, but often they have to confront the situation at hand and do as best their can by just blocking the fires not to spread out further or letting things go as it’s too dangerous to stand against the fires.

Forest fire control officers use leaf blowers to blow over forest fuels so that they will be cleared from the path of forest fires and the fires cannot continue. The blowers can also help extinguish the fires but to ensure that they are completely extinguished, their fellow officers will scan along the track to see if the fires are still left unchecked. Some officers drop drops of water over smouldering rocks or leaves, or otherwise their sweat all day long would become useless if the fires start again.

Normally, forest fires will burn forest fuels on the ground until they have finished. They will then extinguish as there are no fuels left to burn, but often forest fires burn over trunks of trees and from there they will burn them until they collapse. The fires will then sweep across firebreaks or forest paths and spread to the forests on the other side, triggering forest fires over and over this way.

Fallen trees burned by forest fires are natural bridges for forest fires to sweep across firebreaks or forest paths and spread to the forests on the other side.

Must-have devices and food items of Suea Fai when they are on duty. These officers can work without further support for up to three days, relying on just these devices and food items. They are trained to be more tolerant than normal officers as they are expected to work in difficult locations and landscapes, which sometimes take a day or so to get to them.

With only one backpack and their must-have devices and food, Suea Fai can leave their camps in less than 10 minutes for the operation.

Forest fires are the prime cause of PM2.5 in Chiang Mai province. Their root causes, however, are complicated and need proportionate and appropriate policy to address them. As of Mar 4, as photographed, the PM2.5 concentration level over the city of Chiang Mai in the evening was measured at 101 µg/m³.
