On World Ranger Day 2026, Environmental Defenders profiles the community rangers rebuilding broken wildlife corridors and migration routes in northern Uganda and showing people worldwide what it takes to preserve and restore threatened landscapes and species habitats.
In 1972, during Idi Amin’s rule, the government decided to open Aswa-Lolim Game Reserve to settlement, cultivation, and grazing. Half a century later, the ecological damage to that land, which the colonial government had decreed into a wildlife dispersal area and migration route, is still spreading.
But there is hope thanks to Environmental Defenders and a community of rangers passionate about protecting this ecologically rich corner of East Africa.
Daily, rangers patrol the forest boundary of the reserve under active restoration. They carry a water bottle, notebook, binoculars, a camera, and a smartphone loaded with mapping software to watch for poachers and charcoal burning and collect data for the restoration of this important landscape, now named Nyamukino Reserve.
Unlike the colonial government, whose decree dispossessed indigenous communities, Environmental Defenders is establishing Nyamukino Reserve one acre at a time by paying landowners for the land and enlisting communities services as protectors. That community and partnership has fueled commitment.
“We keep the animals safe by patrolling so that when we come across a threat, we can act on it,” says Darius Oyergiu, one of the rangers, who operates in Nyamukino Reserve, a corridor reestablished by Environmental Defenders in the spaces where Aswa-Lolim used to exist.
These rangers carry no ammunition. In the conservation world, people often picture rangers as weary and suited in body armor. That is a unique and common choice in many parts of the world but different from how Environmental Defenders works in one of the most biologically important and pressured wildlife corridors of East Africa.

As we commemorate World Rangers Day, the work at Nyamukino stands out for the passion shown by people like Oyergiu.
World Ranger Day has been observed every year since 2007. It takes place annually on July 31. The theme for 2026, “Rangers: Guardians of a Changing Planet,” is directly in line and speaks to what teams of Environmental Defenders meet and experience daily in Uganda’s Nwoya District, where the climate is shifting, the land is changing hands, and the vastness of savannah and riverine forest that once enabled wildlife to move across the north is closing like a door. However, the people holding it open are the rangers at Environmental Defenders.
“If I protect the animals, my children will also get the chance to see them,” Oyergiu, one of the Environmental Defenders rangers operating in the corridor between Murchison Falls National Park and East Madi wildlife reserve.
What is left of this corridor is still remarkable and worthy of preservation at all costs because this corridor sits inside the Albertine Rift, one of the most species rich regions on the African continent and a recognized biodiversity hotspot.

The wider area holds a documented 144 mammal species, 556 bird species, 51 reptile species, and 755 plant species. It’s home to all the four species of African pangolin, the most trafficked mammals on Earth, two of them endangered. In these areas, you can still find the Grey Crowned Crane, Uganda’s national bird and now endangered, along with the critically endangered Rüppell’s vulture, the secretarybird, and the martial eagle. The area is also home to African savannah elephants, the Rothschild’s giraffe, and lions, in a habitat with trees such as shea, African cherry, and East African mahogany (Afzelia africana), among others.
Wildlife does not know park boundaries or even land borders. An elephant inside Murchison Falls needs open migration routes and a safe dispersal corridor to reach the Nile floodplains and the woodlands beyond. When that habitat is fenced, plowed, burned for charcoal, or turned into grazing land, the corridor disappears, and the wildlife on either side slips toward isolation and local extinction. Reconnecting that migration route is what drives Environmental Defenders work, and why rangers patrol these grounds daily.

This science-based work contributes to local and regional as well as global knowledge for biodiversity conservation. The monitoring, which depends on a blend of citizen and Western science in the corridor between the East Madi Wildlife Reserve and Murchison Falls National Park, started with a rapid biodiversity survey. The survey confirmed the corridor’s richness and the speed of its decline and showed where action could still make a difference. Since 2022, that survey has guided everything on the ground, and conservation-based decision-making remains on track.
The first result was the Nyamukino Reserve, a 210-hectare, roughly 519-acre block of land that has been brought under active conservation management, and as of today, we are conserving over 2,500 acres of reserve. It is a modest footprint, but it is real, protected, and a foothold. From there, the ambition to bring more areas into active management grows into an effort to expand the corridor and wildlife migration routes. That way, wildlife can easily move between Murchison Falls, the former Aswa-Lolim lands, and East Madi without crossing farmland or a snare line. Restoring the degraded stretches means returning native trees to eroded ground, helping the forest regenerate, and hiring local people for nursery work, fire prevention, seed collection, and patrol. This conservation approach is important because it restores connection in fragmented lands, creating, in the process, wildlife migration routes in strategic locations. Connecting fragmented lands to large, protected areas makes it possible for species to move, thereby reducing the risk of local extinction and habitat fragmentation.

To achieve all the above outcomes, the vision depends entirely on rangers. This is because rangers are the ones who must record where a pangolin was seen. They spot a fresh charcoal kiln before it becomes ten and note the first smoke of a dry-season fire. Their patrol data is not paperwork but living documentation to inform acts of conservation. A 2025 study in the journal Conservation Letters described rangers as planetary stewards whose daily observations carry immense, largely untapped value for tracking biodiversity because they are present where researchers rarely reach and are not easily accessible.
This is the case with Oyergiu, for whom the job has deepened his relationship with wildlife. The animals he sees most often are elephants and Grey Crowned Cranes, and he moves among them without fear on either side. “When an animal sees you and you see it, it comes to understand that you mean it no harm, and that strengthens our relationship,” he says. Years of ongoing patrols, he adds, have pushed poaching down across the reserve managed by Environmental Defenders.

Redefining the Ranger
In too many places, the ranger has turned into a soldier, transforming protected areas into sites of violence against communities. Environmental Defenders rejects this model. Rangers at Environmental Defenders carry no firearms and do not use lethal force against people. They are members of local communities, notably the Acholi and Alur, who share this land with wildlife. The rangers are not a force imposed from outside.
That position is a formal commitment and obligation to the work by Environmental Defenders and not a slogan. Ranger work is anchored in the Core Human Rights Principles for Private Conservation Organizations and Funders, as well as the ten principles of the United Nations Environment Programme (UNEP) published in 2024, of which Environmental Defenders is a signatory. The UNEP principles hold that protecting nature and protecting people are the same task, that indigenous and local communities are rights holders rather than obstacles, and that conservation by private organizations must be accountable, consent based, and free of coercion. An unarmed ranger trusted by his neighbors will always learn more, prevent more, and endanger no one, while an armed stranger is feared.
But being local doesn’t shield rangers from danger. According to Edith Nassali Pretty, one of the Environmental Defenders few female rangers, it is harder for a woman on patrol, and a confrontation with a poacher carries a particular risk. Drawn by a love of animals and the land, she does the job anyway, preventing the extinction of species.

None of this comes without danger. World Ranger Day exists because rangers die in this line of work. The International Ranger Federation’s 2026 Roll of Honour records show at least 147 rangers from 40 countries who lost their lives in the line of duty in the year to the end of May 2026. Forty-three of the deaths were homicides, while 32 lost their lives to wildlife attacks. The real toll is almost certainly higher, since many deaths go uncounted. A broader study in the IUCN journal PARKS counted 2,351 on-duty ranger deaths worldwide between 2006 and 2021. That averages close to 150 rangers a year, with homicide—most often during an encounter with poachers—the single most common cause. Welfare surveys describe inadequate training, poor equipment, late pay, and long stretches from family as ordinary conditions of the job.
At Environmental Defenders, rangers experience these realities in their local context. According to Stephen Otiti, who manages Nyamukino, he is always thinking about the safety of his team. He recalls the horror of one ranger seriously injured in an accident while chasing off poachers. The team has basic protective equipment—spears, pangas, and shields—but it is not enough for what they may encounter in the field. To overcome such danger, Otiti wishes for technology-based patrol using drone cameras instead of rangers armed with spears and shields. Environmental Defenders cannot currently afford drones because of financial constraints. For now, Otiti can only continue to motivate his rangers in the ways available to him, which include days off whenever necessary. He also advocates for government and other conservation stakeholders to take the safety of rangers seriously because the wildlife, as he puts it, is a public good.

The Struggle for Conservation Habitat
Land around the corridor is cleared at speed as small-scale farmers seek survival. Commercial operations planting sugarcane and eucalyptus for distant markets, cattle keepers seeking grazing land, and charcoal burners supplying a rapidly growing urban community are a threat too. Since 2003, Nwoya District has lost thousands of hectares of tree cover. Every hectare lost is a piece of the corridor gone, visibly illustrating how habitat does not wait for a funding cycle. The reality is dark for the Environmental Defenders’ kind of work.
For a private conservation organization in a competitive landscape, success can be measured through the acres brought under real protection before they are lost for good. Buying and leasing land for conservation remains one of the hardest things to fund, because too many investors and donors have never accepted that a protected acre is a productive acre. Unlike conservation organization that must rely on bureaucratic and hard-to-acquire grants, a cattle keeper can raise capital to buy land and turn it into grazing almost overnight, and a timber or sugar operation can finance a concession with ease through a bank loan.
For organization such as Environmental Defenders trying to preserve habitat and stop species extinctions, being left to make their case one acre at a time is inefficient. Yet these organizations have to hold the corridor open for pangolins, elephants, and cranes for World Ranger Day to be meaningful.
On a day to celebrate “the guardians of this changing planet,” the financial importance of conservation has to be recognized. Otherwise, the guardians will have nothing to guard.
