bomb them with 6,000 logs from helicopters to fix a decades-old mistake

Historically, the rivers of the Pacific Northwest of the United States They were a chaos of fallen wood, deep pools and irregular currents that prevented the normal flow. The logic marked clean them and remove all the trunks to facilitate the passage of water and transportation, something they did not hesitate to do. The problem is that this has subsequently been seen to be a mistake, and they have literally had to fix it throwing logs into the river with a helicopter. Something that may seem crazy, but that science has endorsed as the best. A bombardment of wood. The project, led by the Yakama Nation in collaboration with organizations such as The Nature Conservancy has reached an unprecedented milestone. They have managed to place more than 6,000 Douglas fir logs and cedar along Central Washington’s 24 miles of rivers and streams. With helicopters. A task that was not easy, and for which helicopters have been requiredsince access by land to these virgin areas is almost impossible without building roads that would destroy the ecosystem that they are trying to save, in a paradoxical way, ‘dirtying’ the rivers. That is why the use of cargo helicopters has allowed the wood to be deposited with surgical precision without touching the surrounding forest floor to do as little damage as possible. An image that has actually attracted a lot of attention on social networks due to the impression of seeing a helicopter dumping wood into a river. A dirty river. Although seeing thousands of logs piled up in a river may seem like a natural disaster, to a biologist it is a perfect work of engineering. And these stacks are called ‘Engineered Log Jams’ and have a very clear meaning. The first is that the logs create deep pools and shadows where the water stays cold, which is vital for the survival of salmon and bull trout in the face of rising global temperatures. Stopping the current. This is another reason why science justifies the need to have these logs in the river, since slowing down the water allows the gravel to settle for the salmon to lay their eggs. Something that is complemented by the possibility of shelter that the trunks provide to hide from predators. Furthermore, by forcing the water to go around the obstacles, the complexity of the channel is recovered, avoiding accelerated erosion of the banks. The backup. As we have said before, it has not been a unilateral political decision, but rather it has had the support of science with different studies. These targeted a survival rate of 78% of fauna after major floods, more than meeting the protection objectives. And the success has been such that they are already being replicated in other parts of the country. The public administration itself is financing similar projects in the olympic peninsula and in counties like Cowlitz they have doubled down, placing up to 8,000 logs in the Grays River. The return of the salmon. This project is not just a question of river aesthetics. It is a battle for food sovereignty and biodiversity. Research in the Elwha River already confirms an immediate positive response with the presence of young salmon in front of these structures. In this way, what was eliminated decades ago because it was considered “garbage” or obstacles to progress, is today reinserted with high-tech helicopters. It is the recognition that sometimes, for nature to function properly, we need to make rivers “dirty” and full of obstacles again.

Shahed drones were a piece of cake for Ukraine’s helicopters. Russia has just transformed them into its biggest nightmare

In it huge catalog of innovations improvised measures brought by the war in ukrainefew are as revealing as the decision that Russia has taken to address one of the main vulnerabilities of its drones. In essence, they have turned the Shahed-136 (symbol of its saturation strategy through cheap and disposable platforms) in a rudimentary anti-aircraft fighter. The mutation. What was born as a suicide drone with autonomy to travel hundreds of kilometers following pre-programmed routes has been transformed, in some variants, into a system piloted in real timeequipped with cameras, modems and now with the R-60 missilea veteran infrared-guided missile from the 1970s that, despite its compact size, retains the lethality of a weapon capable of cutting a helicopter in two with its load of continuous rods. The broadcast images by Ukrainian organizations and electronic warfare experts confirm the presence of the R-60 mounted on the Shahed’s noseand the interception of one of them by a Ukrainian Sting drone illustrates that Russia is experimenting with the idea of ​​​​transforming a disposable projectile in a reactive vectorcapable of confronting the devices that, until now, acted as unpunished hunters of these platforms. The new tactical ecosystem. The success of the Ukrainian helicopters in intercepting Shaheds (with devices sporting dozens of shoot-down marks and crews accredited with hundreds of downed drones) had turned these aircraft in key pieces of low-level air defense. The combination of moderate speed, predictable trajectory and total lack of situational awareness made the drone a almost static whitevulnerable to cannon blasts or volleys used at close range. But the introduction of the R-60 upsets that balance: although the platform remains clumsy, slow and limited in maneuver, the simple fact that some drones can carry missiles will force Ukrainian pilots to rethink their proximity to the target. Each interception stops being a procedure and becomes in an unknown about what version of the enemy they will encounter. Extra ball. Even if the actual kill capability of the armed Shahed is small (and the operational window for targeting with a short-range missile is narrow) the statistical nature of swarm warfare change the calculation: In thousands of launches, just getting into a good position will be enough to cause the loss of a valuable helicopter. Technical limitations. The R-60, known by NATO as Aphidwas designed for supersonic fighters, not slow drones intended as loitering munitions. Its integration into the Shahed poses obvious challenges: the operator must manually retarget the drone until it is pointed at the target, achieving an adequate angle to allow the infrared seeker to acquire the thermal signature and maintain alignment long enough to authorize the shot. He narrow field of vision of the missile, the Shahed’s low maneuverability and the possibility of helicopters using infrared flares reduce the chances of success. However, historical experience shows that even imperfect weaponry can achieve victories if the tactical environment favors it. Remains of an intercepted Shahed with the R-60 attached The precedent. If we go back we have the Predator armed american with Stingers in 2002 (failed but deterrent), which reveals that these configurations do not seek air superiority, but rather force the enemy to act with caution. Just as Ukrainian unmanned ships were armed with missiles To scare away the Russian helicopters that were harassing them, Russia adopts the same defensive-offensive logic: a single one of these armed drones, hidden among a swarm of externally identical devices, forces the adversary to increase distance, use more expensive means or modify its interception doctrine. Drones against drones. The Shahed armed with an R-60 is not, by itself, a transformative weapon. It is, however, as symptom of evolution continued unmanned combat. Russia has expanded the Shahed family into versions with real time controljet variants already produced in its own factories and possible improvements based on artificial intelligence for dynamic target identification. Ukraine, for its part, develops interceptors low-cost that allow us to shoot down Russian drones without risking manned aircraft or spending expensive missiles. Every innovation generates a countermeasure: if Ukraine popularizes cheap hunting drones, Russia studies equipping the Shaheds of tiny turrets or new sensors, and if these become reactive, Ukraine adapts its doctrines and strengthens its electronic warfare. The conflict has entered a phase where the value is not in the perfection of each platform, but in the ability to produceadapt and deploy thousands of them in an environment where the line between offensive and defensive becomes blurred. The most dangerous sky. It is the result of these advances. The introduction of Shahed-R-60 marks a turning point because it erodes one of the few stable advantages that Ukraine had maintained: the capacity of its helicopters to hunt drones with relative safety. Now each aircraft must consider the possibility, however remote, of facing a missile that was not foreseen in the original mission design. This not only complicates interceptions, but forces disperse risks and rethink routes, altitudes and speeds. The Ukrainian sky, already saturated with suicide drones, cruise missiles, loitering munitions and manned aircraft operating in densely contested airspace, add another variable to an operational equation in constant mutation. And it is likely that this is just the beginning: the integration of missiles is a first step towards drones that, in addition to attacking by saturation, can defend themselves or even escort other devices in combined waves.

Australia has executed 750 Koalas with snipers uploaded to helicopters. Even if it seems, it was for its good

The Koalas are one of the most recognizable (and probably beloved) symbols in Australia and in part of their territory, such as New South Wales, Queensland or the Territory of the Australian capital They are considered in danger of extinction. Neither one nor the other has prevented a group of snipers being killing hundreds and hundreds of these marsupials in the BUDJ BIM National Parka wide nature reserve located to the south of the country. They do it from helicopters, with the support of the government and supposedly for “Humanitarian reasons”. The big question is … why? Snipers, helicopters and koalas. A priori are three concepts without too much relationship with each other, but those are the protagonists of the controversy that has shaken in recent days the Victoria statesouth of Australia, where the Budj Bim National Park is located. Local press days ago He started informing that hundreds and hundreds of koalas were sacrificing there. If the news was not surprising (and sad) already won even more impact When it transcended How the killing is carried out: animals are dejected From helicopters with the aid of snipers. All this of course with the PLACET of the Department of Energy, Environment Climate (DEECA), The conservation authority, as confirmed recently The ABC chain. Click on the image to go to Tweet. How many koalas have they dejected? The exact encrypts can dance based on the source that is consulted, but they all agree on something: the campaign is ending hundreds and hundreds of koalas in the region, more than half a thousand. In the middle of the month, as the news progresses, Yahoo News assured that had sacrificed between 600 and 700 marsupials. There are activists who raise However, the total balance of the measure above the 700 copies And in the last hours Europa Press (AP) rounded the figure talking about “Up to 750 koalas”. And what is the reason? Humanitarian reasonsaccording to The authorities allege of Victoria. The sacrifices are part of a precipitated euthanasia campaign in turn, the government insists, for The forest fire that devastated in March around 2,200 hectares of the Budj Bim National Park. The flames would have affected part of the fauna (including the koalas) and also devastated 20% of the Natural Reserve. The result: injured animals, abandoned and have seen how much of the eucalyptus they need to feed. No other options? Although the use of helicopters and snipers can be striking (and unorthodox), the Victoria government assures that the decision was adopted after “exhaustive evaluations” and that the koalas that are being down are “severely affected” by the forest fire. Moreover, Deseca claims that he has not found other alternatives to face the problem beyond hiring professional shooters and uploading them to helicopters. “All other methods considered are not adequate given the impossibility of safely accessing large areas of the affected landscape due to the remote location of the animals, which are often found at the top of the treetops, the extremely rugged land and the safety risks that lead to work in an area affected by fire and with damaged trees,” James Todd explainshead of Deca, to Vox Magazine. Do you all think the same? No. and good proof is that the news about the campaign has unleashed an intense controversy in the state of Victoria, the Australian team and beyond even the country. The reason: the scope of the measure. The Animal Justice Party He has denounced that local authorities “are not making any effort” to verify whether females dejected from the air have, for example, young. AND Alliance for the Koalas It even goes further and denounces that technicians have no way to check from the heights if the specimens they deduct are really in “bad conditions.” “It seems very indiscriminate,” Rolf Schlagloth agreesresearcher at the CQUNIVERSITY Australia specialized in Koalas. “The rescue should always be the first option if possible.” Beyond shots and helicopters. Among the activists and experts, not only has the selective koala slaughter bothered. Throughout the last days, voices have also been raised that they see in what happened in Budj Bim An example More than “the poor management of the species and its habitat” and warn of the effect of eucalyptus felling or the threat of global warming and fires. “We cannot eliminate forest fires completely, but more healthy forests and with greater continuity they can help reduce the risk and severity of the fires. The Koalas habitat must be extensive and be connected, and the management of the blue eucalyptus plantations must take into account the koalas,” SCHLAGLOTH ZANJA In a recent interview with Vox Magazine. Taller slopes. That last nuance is important. In Another article Posted in The conversation By Liz Hicks and Ashleight Best, two law experts at the University of Melbourne, remember that Budj Bim National Park is surrounded by commercial eucalyptus plantations, hectares full of foliage that end up receiving koalas in search of food. The problem is that this availability of the sheet leads to the populations of the marsupial to increase. And once the plantations are talked, those same animals return to the protected park. The result: greater pressure in the area and greater vulnerability to fires such as March. “Animals point out that logging is one of the reasons why Budj Bim had so many koalas,” They add.
