Addo Elephant National Park meeting jumbo accommodation challenge
Since the establishment of Addo Elephant National Park in 1931 for the protection of the remaining 11 elephants in the area, the population has done extremely well.
So much so that it led to a steady enlargement of what is known as the Addo main camp section from 1955 to 2015 to ensure other biological components are not affected by the elephants.
The park is now home to more than 800 elephants in various sections and biomes.
The largest single expansion included the addition of the Colchester section towards the south of the park in 2010, with the dropping of fences between the sections.
The combined main camp/Colchester section is now about 268km² in size (Lombard et al. 2001) and contains several boreholes and earthen dams due to the lack of natural rivers in this section of the park.
Addo expanded substantially over time and by 2022 it had seven areas separated by fences, interspersed with private land in some cases.
This provided opportunities for elephant range expansion, with the main camp serving as the source for other sections of Addo and externally.
For instance, authorities translocated four juveniles from Addo to the Pilanesberg National Park in 1979 (Hancock, 1984) and a further 11 bulls to various private game reserves across SA in 2005.
In 2003, 61 elephants were moved from the main camp to the Nyathi section, while four bulls were introduced from Kruger National Park.
The Darlington section received 28 elephants from the main camp/Colchester section in 2018.
Fencing of the park in 1954 confined the elephants to an area which led to most of the main camp being used by elephants and subsequently resulted in impacts on vegetation structure and sensitive species (Lombard et al. 2001; Kerley & Landman, 2006).
To alleviate these impacts, the main camp was expanded into the Colchester section where water provision was limited.
However, the main camp/Colchester section was not big enough to significantly change elephant space use and therefore other management interventions to limit population growth, such as elephant contraception and water availability gradient, had to be implemented.
Recent studies have shown that historical management approaches have generally not been able to impose spatial and temporal limitations on elephant space use in the main camp/Colchester section (Guldemond et al. 2022).
This in turn could lead to impacts on other biodiversity components if management interventions are not continued and by expanding land availability through the consolidation of current sections and the addition of new land to Addo.
It is for this reason that the relocation of 42 elephants from the main camp to the Kabouga section (towards the north of Addo), last month was undertaken.
From observations of the various family groups since through nine tracking collars, it appears they are exploring and settling well into their new home.
As recently as June 3, Addo Elephant National Park biotechnician Joshua Roberts was in the area servicing cameras when he came across the youngest of the lot, aptly named Kabouga, and his herd — all looking healthy and happy.
The consolidation of the neighbouring Kabouga and Darlington sections is planned, which will provide the two populations with an even greater area to roam. Charlene Bisset — SANParks regional ecologist

Pretoria Zoo celebrates World Giraffe Day by welcoming newborn calf Enzo
When the global community came together to celebrate World Giraffe Day on June 21, the National Zoological Gardens (NZG) in Pretoria had its own reason to celebrate with the arrival of a giraffe calf earlier this month. Born on June 8, the young giraffe is the fifth addition to the NZG's giraffe herd. The birth coincided with World Giraffe Day, an initiative by the Giraffe Conservation Foundation (GCF) to honour the world's tallest land animal on the year's longest day. The calf was born at the zoo to Momo, an 11-year-old matriarch known for her calm and independent nature. According to Carol Thobela, curator of carnivores, pachyderms, and farm yard at NZG, the calf has begun to show a strong personality. 'We named the calf Enzo, meaning 'ruler of the estate'. It's a strong, bold name that suits the energy we have seen. Even though we don't yet know if Enzo is male or female, the name reflects the confidence and spirit of this little one,' said Thobela. NZG director of animal conservation Tracy Rehse highlighted the importance of understanding giraffe subspecies in supporting global conservation science. 'According to new genetic classifications, the NZG giraffes are assumed to belong to the South African giraffe subspecies Giraffa camelopardalis giraffa, though genetic testing has not yet been conducted to confirm this,' said Rehse. 'Understanding subspecies has helped us align our animal management practices with conservation science and ensures we're contributing meaningful data to global conservation efforts' The giraffes at NZG live in an environment tailored to their natural behaviour and health needs. Elevated feeders mimic tree-top browsing, while night shelters and a surrounding wet moat provide safety and comfort, accounting for giraffes' natural reluctance to cross water. The NZG herd includes a mix of distinctive personalities, including: Tiago, who was born in 2020 and hand-reared by staff, is known for his playful and affectionate nature. Azuri, who was born in 2022, is confident and observant and is often found surveying the zoo from his favourite lookout mound. Bonito, the nine-year-old breeding bull, is food-driven and dominant, approaching staff only when browse is on offer. South African National Biodiversity Institute director of marketing, communications and commercialisation Nontsikelelo Mpulo stressed the broader significance of World Giraffe Day. 'World Giraffe Day is not only about admiring Africa's gentle giants. It is a day dedicated to raising awareness and support for the conservation of giraffes, who are increasingly threatened by habitat loss, poaching and deteriorating ecological infrastructure,' said Mpulo. 'While promoting animal welfare and public education, the zoo also plays an important role in national conservation efforts. Though giraffes are locally classified as Least Concern, the species is globally listed as Vulnerable on the IUCN Red List, with some subspecies facing a higher risk of extinction.' TimesLIVE

Teaching is an act of nation building
As we remember and honour the courage of the youth of 1976, we must also celebrate and support those who continue the struggle for justice and dignity in the classroom. Youth month celebrates the activism of young people, but teachers have been organised activists since the South Africa observes Youth month in June to honour the The Despite these oppressive systems, black and coloured teachers have resisted segregation since the early 1900s. They did so not only through protest and activism but also by serving as pillars of critical thinking, dignity and cultural resistance in their classrooms and communities. Teachers were seen as carriers of hope and social mobility. Fast-forward 96 years, in the final year of my undergraduate studies in 2009, I volunteered with two afterschool programmes for primary school learners in Makhanda. Like many South Africans, I had read the shocking statistics about our country's low literacy rates and the poor matric results that dominated headlines year after year — a hangover from apartheid. As I began working with learners in afterschool programmes, I realised that behind their smiling faces lay a real crisis. I saw first-hand how an inability to read kept children from learning new concepts, passing and succeeding at school. One afternoon, I asked a group of grade 2 learners to write letters to their mothers for Mother's Day. A little girl named Chandré asked me how to write the word love. I spelled it out and sounded it out phonetically. She looked at me with a blank stare. She had been in formal schooling for two years but could not recognise letters or sounds. At that moment, I knew I wanted to become a teacher. Teaching holds a special place in my heart; I am a fourth-generation teacher. My great-grandfather, grandfather and mother all served in the profession until they retired. During my childhood I saw the effect they had on others' lives. To this day, when I meet someone who attended Newell or Cowan high schools in New Brighton, Gqeberha, from 1959 to 1995 and I mention my grandfather, Today, I lead a project that works with a network of change agent teachers who remind me of my grandfather. I see them take on roles beyond their job description: acting as social mothers and fathers, emotional lifelines and trusted adults for learners navigating the realities of inequality inside and outside classrooms. Despite their essential role, the narrative about teachers has shifted, but not for the better. Teachers in South Africa often feel undervalued. While remuneration plays a part, value is also communicated in how we speak about teachers. It's in the way parents frame educators to their children, in how we as society recognise or ignore their efforts. In a As we remember and honour the courage of the youth of 1976, we must also celebrate and support those who continue the struggle for justice and dignity in the classroom. It's time that we rally behind our teachers in a way that truly appreciates the value of the teaching profession. We need to support teachers in ways that translate both on the ground and at policy level. Andisiwe Hlungwane is the project lead of Teachers CAN, a network of change agent teachers.

School sampling tests find storage tanks contain unsafe water
Pupils from Douglas Mbopa Senior Secondary School in the Eastern Cape, test water using WaterCAN kits. (Photo: WaterCAN) A Of 19 tank water samples tested in eight provinces, 14 (about 74%) were found to contain bacterial contamination, including E coli, rendering the water unfit for human consumption. Of the 53 schools that upload valid data, 23 returned results showing water was unsafe to drink. In total, 43% of the 53 samples tested showed bacterial contamination. This included 23% of tap water sources and 66% of river samples. But storage tanks — installed widely for commercial and private use to compensate for failing municipal water infrastructure — showed the highest rate of contamination. The tests formed part of a random sampling project led by nonprofit group The campaign was designed to coincide with World Water Day and involved 95 schools. Water was tested from taps, rivers and tanks, the primary sources of drinking water at participating schools. The learners were trained to use citizen science water test kits, which checked for chemical and microbiological contaminants such as nitrate, nitrite, phosphate, chlorine, bacterial contamination from total coliforms and E coli, as well as the acidity, alkalinity and hardness levels of the water. Ferrial Adam, the executive director of WaterCAN, said the results showed the importance of monitoring water tanks at schools. 'We don't know how often they're maintained; we don't know what their source of water is. Some of them get municipal water, some of them are rainwater-harvested, some of them are [from] boreholes. But in all of that, whatever their source, there are issues that need to be raised.' She said the results of this small project were worrying. 'If we look at the government's The project included online and in-person training sessions for teachers and learners. WaterCAN's report acknowledges that only 47% of schools submitted test results, because of schools being closed for the holidays, data upload difficulties and other logistical barriers. 'It is critical to emphasise that the data reflects only a snapshot of the broader reality across South Africa's thousands of schools,' said the report. 'While we cannot generalise about the water quality status of all schools, the findings do highlight systemic concerns that likely apply nationwide, most notably, the urgent need for an improvement to water and sanitation infrastructure, consistent water quality monitoring and routine maintenance of tanks and other storage systems within school premises. The Collaboration partners plan to engage the DBE [department of basic education] about this.' Herman Mayer, the education lead at the Leap Institute, said he enjoyed the campaign, which provided experiential learning to children. 'It's fantastic that we could involve schools in something that is critical to our country's prosperity. 'And in the end, education remains the single biggest and easiest way to change people's living conditions and opportunities and it's the quickest and easiest way that we can remove some of the inequality in our society.' As at home, children need clean, safe water at school, he said. 'The education department is responsible to provide conditions that are conducive to learning. It's taken us 30 years and we still haven't got rid of, for instance, schools with pit latrines, schools with no running water. 'We need to help the department. We also need to put pressure on the department as well as the provincial departments to make sure that all schools have clean and safe drinking water and all types of sanitation.' He added that young people need to understand their relationship with water, given that it is a scarce resource. They also should learn about water being polluted and that with scientific knowledge water can be preserved Nomsa Daele, WaterCAN's citizen science training coordinator, said the results would be used to alert affected schools; support follow-up testing and discussions with local government; and advocate for systemic solutions from the department and municipalities. 'This is a wake-up call, and it calls for urgent action and advocacy work,' she said. In 2024, South Africa had 24 850 schools, of which 22 381 were public. Government data suggesting nearly half of all public schools lack flushing toilets and about 2% have no running water. But a report by the International Labour Research and Information Group, has suggested that the number without functional water systems could be as high as 25%. Adam added that the project was not just about getting the results. 'It was about how do we build that next layer of water warriors in South Africa.' The project was a collaboration between WaterCAN, the Wildlife & Environment Society of South Africa, Adopt-a-River, Johannesburg City Parks and Zoo, Cape Town and Nelson Mandela Bay science centres, Makhanda River Rescue and the Leap Institute.
