Kariba weed came, saw, but didn't conquer Lonehill Dam
It took Johannesburg City Parks and Zoo (JCPZ) R300 000 and 20 days of hiring equipment to clean up the aggressive Kariba weed at Lonehill Dam. The staggering price included the equipment's operator and fuel.
Councillor David Foley, from Ward 94, was onsite on June 6, with Rob van der Pauw, putting in more eco granules to ensure that the nine week project to rehabilitate the dam was not in vain. Wendell Africa, stakeholder from JCPZ doing oversight, was at the dam at the same time, and they could all see that the dam is no doubt getting better everyday.
Foley said the eco tab granules will purify the water resulting in the reduction of nitrates that the Kariba weed feeds on. 'It breaks down the sludge at the base of the dam, purify the water so it becomes clearer.'

He said the food source of the weed, as in the nitrates, will reduce and limit the growth of the weed, therefore it should die off over time.
'The ecosystem will recover. A good test will be when the frogs return, which means the environment is at a suitable level for nature to thrive. The cost of the eco tab granules will be determined by the success of the exercise, but should not be more than R50 000, as per the initial proposal submitted to JCPZ.'
Kariba weed is a free-floating plant that does not attach to the soil; instead, it remains buoyant on the surface of a body of water. The fronds are 0.5–4cm long and broad, with a bristly surface caused by the hair-like strands that join at the end to form eggbeater shapes.

The plant has been hovering over the Lonehill Dam since November last year, and since then, experts and authorities have been splitting hairs about how to stop the invasive plant before it harms the fish in the dam.

Historical trip educates Westgold learners about Youth Day
On Youth Day, Westgold Primary School's Soul Buddyz Club embarked on an educational trip to the Freedom Park Heritage Site and Museum to help learners understand the history. • Also read: Youth Day is more than a day off, says local activist 'This event aimed to educate our learners about the country's rich history and the importance of this day, which honours the bravery and sacrifices of the youth who fought against apartheid,' explained school spokesperson Mariska du Plessis. She said during their visit, the learners had the opportunity to reflect on the past at the Wall of Remembrance, where the names of fallen heroes are etched. Mariska further stated that the special experience served as a reminder of the struggles endured by those who fought for a better life. 'The learners had a moment of silence at the Garden of Remembrance and paid their respects to the sacrifices that were made on Youth Day. This educational trip was designed to inspire our learners to appreciate the value of history and the importance of preserving it. 'By walking through the Freedom Park Heritage Site and Museum, they gained a deeper understanding of the country's journey to democracy and the role that young people played in shaping its future.' The Soul Buddyz Club hopes that this trip will set an example for other clubs to follow while also motivating them to take learners on similar trips. 'By doing so, we believe that we can inspire and motivate those around us to prioritise experiential learning and foster a deeper appreciation for the country's heritage. Through initiatives like these, we aim to empower our learners with knowledge, empathy, and a sense of responsibility. We want them to become active contributors to the country's ongoing journey towards growth and development,' Mariska concluded.

Church hosts Education Sunday to honour graduates
SASOLBURG – Every year, the City of Love & Restoration – Full Gospel Church in Zamdela hosts a special service to honour its newly graduated congregants. This year was no exception, as the church once again celebrated academic excellence with a heartfelt and uplifting ceremony on June 15. The service was graced by the presence of the Deputy Minister of Basic Education, Dr Reginah Mhaule, who joined graduates, learners, and church leaders in recognising the accomplishments of the Class of 2024. The event was hosted by Bishop Thabiso Mashiloane and Lady Bishop L. Mashiloane, with Dr Ncha skillfully leading the programme. Elder T.J. Sekolanyane opened the service by reflecting on its purpose: to commend graduates who have overcome challenges on their educational journey, and to inspire current learners to remain committed to their studies. Throughout the event, a variety of speakers delivered motivational messages to the congregation. Among them were Dr Mpho Ramoliki and Thandiwe Pino, who shared powerful words of encouragement. Dr Ramoliki urged learners to be discerning in their choice of role models, stating: 'If you are so thirsty that you want to drink from every cup presented to you, you will be poisoned. Don't make slay queens your role models.' Delivering the keynote address, Dr Mhaule congratulated the graduates and emphasised that learning does not stop after matric. She encouraged young people to embrace education as a lifelong journey and to adopt an entrepreneurial mindset to help combat unemployment and contribute positively to their communities. The celebration concluded with a symbolic gift handover to the graduates by Professor Segalo, Bishop and Lady Bishop Mashiloane, and Dr Mhaule, a gesture recognising the graduates' hard work, resilience, and dedication.
