Predator-Proof Bomas – A new dimension in human-wildlife conflict resolution

As the sun sets in the Maasai Mara, Narok County, neighbouring herders usher their livestock to the bomas (livestock enclosures) for the night. For Joshua Salaash the experience is different today – Joshua is leading his herd of cattle into a newly constructed eco-friendly and secure predator-proof boma.

In March 2020, Joshua lost six sheep to a lion attack at night. Before the construction of the new boma, the return of livestock each evening marked the beginning of a long restless night of listening for any commotion and shooing away predators.

“The possibility of losing livestock to a lion or a hyena was very high back then. My old boma was not strong to prevent attacks. It had many loopholes that made it easy for predators to breach and prey on my livestock. With this new shed boma, I can sleep more comfortably,” says the 37-year-old.

Maasai Mara is a human-wildlife conflict-prone area because of the proximity of human settlement to wildlife conservancies. Humans, livestock, and wildlife share the same space. Most conservancies are vast and not fenced, leaving wild animals free to roam, occasionally straying into villages and attacking livestock. Most herders in the Mara ecosystem say they have had their livestock preyed on by wildlife several times.

Wildlife attacks on livestock result in retaliatory assaults most of the time. Affected herders hit back by poisoning carcasses of sheep, goats, or cattle with pesticides. The poison is aimed at the predator, but it kills non-target species such as vultures in the process. In Kenya, these poisoning incidents are responsible for 60 percent of vulture mortality.

Conservation organizations working in the Mara ecosystem have devised new tactics to reduce human-wildlife conflicts in the area. Construction of the predator-proof bomas is one such intervention. Nature Kenya has partnered with the Mara Predators Conservation Programme to construct five predator-proof bomas in the Maasai Mara ecosystem.

The selection of five predator-proof bomas beneficiaries was conducted in June 2020. Officers from Nature Kenya and the Mara Predators Conservation Programme met with representatives from conservancies, the local administration, and local communities. The five beneficiaries were chosen based on the history of wildlife attacks, proximity to human-wildlife conflict hotspots, and assurance of permanent residence in their respective areas.

“Human-wildlife conflict issues are sensitive because they touch on the livelihoods of the affected herders. We had to carefully select beneficiaries to best bring out the advantages of this new initiative to the communities as part of solving human-wildlife conflict,” says Simon Shati, a Vulture Liaison Officer working for Nature Kenya.

The predator-proof bomas are constructed using recycled plastic poles that are surrounded by triple-twist chain link and barbed wire. A steel gate is installed to control livestock entry and exit. The boma is impenetrable for large carnivores as it is sealed all round. The recycled plastic and corner metal poles are sunk two feet deep into the ground. Their pits are filled with mortar to make them stable.

“The poles are high, standing at about two metres tall, which is high for a predator to scale up,” says Simon.

One boma can comfortably hold a herd of 700. Simon says that in addition to being made from a material that can withstand harsh weather and pests like termites, the herders do not need to cut down any trees.

Already the effectiveness of the bomas has been tested unintentionally by recent attacks. In the small village of Oloolchuura, sandwiched between two conservancies and the Maasai Mara Reserve, Siloma Ole Reiya considers himself a lucky man. On one corner of his shed boma the wire mesh is slightly deformed outwards following a commotion by cows. The deformity is proof of the events of the night of July 7, 2020 when a pride of lions unsuccessfully attempted to break into the predator-proof boma.

“I would be counting it as my fourth loss of animals this year were it not for this new shed. The layers of chain-link and barbed wire made it impossible for the lions to come close to the herd. Thankfully I was also able to scare the pride away in good time,” says Siloma.

A few kilometers away in Ingila village, Letutuk Tira’s homestead is not easy to miss; it is surrounded Naboisho and Olare Motorogi conservancies and the Mara Reserve. For Letutuk, predator attacks are a common phenomenon. Letutuk is another beneficiary, and his account of a July 14, 2020 attack reads like a scene from a movie:

“The big cat pounced on my motorbike, damaging the headlight, before attempting to enter the locked shed. I fled from the scene and I must say I am fortunate to be alive and for my animals to be safe,” says Letutuk.

The improved bomas are one among many projects aimed at reducing the cases of predation of livestock by wildlife. Nature Kenya has since 2018 been working with the Maasai Mara Wildlife Ambassadors, the Maasai Mara Important Bird Area (IBA) site support group (SSG), to create awareness about wildlife poisoning and its consequences. The group conducts market and village outreaches, using traditional dances and other forms of performing arts to spread conservation messages. Nature Kenya has recruited “vulture volunteers” who are members of local communities engaged in vulture conservation activities. All these efforts are geared towards helping communities to take up better human-wildlife conflict prevention mechanisms.

There are prospects of expanding this project to other areas within the Mara Ecosystem, and to Kajiado County in the coming months.

Cut one, plant two

One of the results of deforestation is global warming. Trees and plants take in carbon dioxide and release oxygen back into the air. When we cut trees, a lot of the carbon dioxide released finds its way into the atmosphere. The carbon combines with other gases and absorbs sunlight. Normally, the radiation is supposed to escape into space but these gases, which last up to centuries, trap the heat in the atmosphere and causes the planet to get hotter. This is known as the greenhouse effect.

At St. Andrews Preparatory School, Turi, we are always encouraged to do something that would benefit the community, so I decided to plant some trees to help reduce the amount of deforestation and its impacts on our atmosphere. At school, we have a program called ‘Love in Action’. As part of this program, we eat simple lunches and wear our home clothes. We also contribute Ksh.100 from our tuck money to give to the people in need at the school’s charity, the Turi Children’s Project.

We also try and reduce, if not eliminate, food wastage. With less wastage, there would be less need for more land for agriculture. This would reduce deforestation. More land would also be available for the planting of trees.

People also cut down trees for fuelwood for cooking and to make homes warm. Trees also provide timber used for furniture and building. This means that we need to use trees sustainably, by planting as much as or more than we cut down. That’s why I decided to be part of the solution and plant trees, not of the problem by cutting them down.

Because of their many uses, we cannot stop cutting down trees completely. For that matter, for every tree we cut down, we should plant one or two in return. That way, we will continue to use trees sustainably for timber and fuelwood. That way, we will have a win-win situation.

Patricia Owiyo is a budding 11-year-old naturalist who is on a mission to conserve Kenya’s foresst. Patricia is a pupil at St Andrew’s Preparatory School Turi, Nakuru. The disruption of the school calendar by the Covid-19 pandemic made her come up with an initiative to grow trees in degraded forests. Patricia funds her tree-growing activities from savings made from sales of her handicrafts. Last month Patricia donated 400 tree seedlings to the Kijabe Environmental Volunteers (KENVO) for planting in Kereita forest, Kikuyu escarpment. Through friends, Patricia was also linked to Nature Kenya for support and guidance in her dream journey to grow at least 1,000 trees by 2021.

Rice growing boosts forest restoration in the Tana River Delta

Until recently, Ozi was considered a major community grown rice-producing area in the Tana River Delta. Seawater intrusion, however, forced communities to abandon rice growing in the area. At the time, the rice variety cultivated could not survive in brackish waters. Communities sought alternative livelihood activities, some of which were not good for the mangrove forest found in the area.

“The abandonment of rice growing in Ozi hurt the surrounding environment, particularly the mangrove and Ozi forests. Harvesting of mangrove poles was one of the alternative livelihood activities people got involved in. Communities also started clearing vegetation for farming further into the natural forest, and this was not good for the environment,” says Serah Munguti, then Policy and Advocacy Manager at Nature Kenya.

Since 2019, Nature Kenya, with support from EU Rebuild/CISP, has embarked on a new initiative aimed at reducing degradation at the Ozi forest and adjacent areas through the revival of rice growing.

Correlation between food insecurity and habitat loss

The aim of this initiative, Serah, points out, was to improve on food security as well as safeguarding the Ozi forest’s unique biodiversity.

It all started when Nature Kenya supported 126 households in Ozi village, representing 936 individuals (470 males, 466 females), with 2,571 kg of certified ITA 310 (NIBAM 110) rice seed. This seed variety was recommended for the area by experts from the Ministry of Agriculture.

ITA 310, according to Infonet- Biovision (https://www.infonet-biovision.org/PlantHealth/Crops/ Rice), is a long-grained rice variety that matures in 110-120 days. This variety is suited for growing in irrigated lowlands and is tolerant to rice blast and the Rice Yellow Mottle Virus (RYMV). ITA 310 is grown for subsistence and commercial use. It has a grain yield of 3-5 tonnes per hectare (t/ha).

Out of the supported households, 91 harvested 867Kg of paddy rice per acre, translating to 79 tonnes of unprocessed rice. The harvested paddy rice, working with a conversion rate of 65%, yielded 51 tonnes of milled rice valued at Ksh 3,076,983 at farm gate and Ksh 3,589,814 at market prices. This translated to an average income of Ksh. 33,813 and Ksh. 39,448 per household at farm gate and market prices respectively. These results of the rice harvest constituted a 33.83% and 61.56% increase in annual household incomes for male and female-headed households respectively at farm gate prices. At market prices, the annual household incomes increase by 39.53% and 72% for beneficiary male and female-headed households respectively.

Demand for the new seed variety has also increased as more farmers request for it. Nature Kenya, once again, has supplied 4.2 tons of the rice seed to the farmers this year, targeting 247 farmers.

Said Nyara, a rice farmer in Ozi, is upbeat about this initiative. Nyara, who has a three-acre farm, harvested 30 bags of 50kgs last season.

‘The rice variety is good. It is resistant to salt and yields a better harvest,” says Nyara, adding that it also fetches better prices in the market.

Mwanaharusi Bakari, another rice farmer from Ozi is excited to be growing the rice this year.

‘It’s my first time growing this rice variety, and I’m happy about it. I saw other farmers having a good harvest last season. This has inspired me,” she says.

Mwanaharusi intends to put two out of her three acres under rice cultivation.

Environmentally, the revival of rice growing has somehow also contributed to an increase in mangrove forest cover.

“Boosting household incomes through rice growing is one way of reducing over-reliance on forest products for livelihoods at the Tana River Delta. Nature Kenya is working with different communities spread across the delta to promote sustainable use of natural resources,” says Serah.

The Tana River Delta Key Biodiversity Area (KBA) is designated as a wetland of international importance (Ramsar site) and is one of the most important wetlands in Africa. In 2011, Nature Kenya led a collaborative effort of various stakeholders in the development of a Tana River Delta Land Use Plan (LUP) that was guided by a Strategic Environmental Assessment (SEA). The process was concluded in 2015. The land-use plan has since been approved and adopted as a policy by the Lamu County government.

The land-use plan is now in its implementation phase. Nature Kenya has also been promoting the Indigenous Community Conservation Areas (ICCAs) approach. Community Conservation Areas are biodiversity-rich areas partially or largely managed by local communities.

Bird and human mutualism: The Greater Honeyguide and honey-hunters

Greater Honeyguides know where bees’ nests are located and like to eat beeswax; humans know how to subdue the bees using fire, and open the nest using axes. By working together, the two species can locate the bee nest, overcome the bees’ defences and gain access to the nest, thus providing beeswax for the honeyguides and honey for the humans.

This specialised relationship is a rare example of animal-human cooperation – mutualism – that has evolved through natural selection. Pioneering research was done in Kenya by Dr Hussein Isack in the 1980s, who first demonstrated scientifically how the mutualism functions. Now we have the opportunity to take part in a citizen science study.

Researchers from the University of Cambridge in the UK and the University of Cape Town in South Africa are working in close cooperation with rural honey-hunting communities in Africa to study the foraging partnership between the Greater Honeyguide and the human honey-hunters whom it guides to bees’ nests. They want to understand the ecology, evolution and conservation implications of the honeyguide-human relationship, as a window into the origin and maintenance of mutually beneficial interactions between species (mutualisms).

If you have seen or heard a Greater Honeyguide anywhere in Africa, and whether or not it guided you, please tell them about it! Visit the citizen science project at <Honeyguiding.me> for more information and to submit a sighting.

“The honeyguide-human relationship is currently dwindling throughout Africa, and before it fades away, we need to understand this ancient part of our own species’ evolutionary history in those few places where it still thrives. This is relevant to conservation, because mutualisms can have wide reach in shaping ecological communities,” reads an excerpt from the Honeyguide Research Project.
