Hunter Miller, a 14-year-old from Somerset West in Cape Town, started his rhino conservation journey at the age of just eight, and has since raised close to R400 000 for the protection of rhinos threatened by poachers.

Rhino Conservation efforts since 2015

According to Hunter’s BackaBuddy page, ‘Raise a Baby Rhino with Hunter’, the little boy began raising funds for an orphaned White rhino called Osita, who was found at Aquila Private Game Reserve in the Western Cape on New Year’s Eve in 2015.
  • “I learnt so much from that one special rhino and how every rhino’s life is important. After years of hard work, Osita was successfully released back into the wild and I decided that I needed to help as many orphaned and injured rhinos around South Africa to have the same second chance at life.” Mitchell says on his page.
According to Tourism Update, R400 000 funds that were raised, was done so through awareness talks at schools, civvies days, talks at corporate events and other ventures. Hunter also launched a rhino sock collection in 2019, which was supported by Pick n Pay clothing, and his rhino masks are even sold at shops in the Kruger National Park.

Hunter plans to be a veterinarian one day and hopes to raise even greater awareness about rhino conservation, reports News24.
  • “I want to keep educating future generations about their responsibilities to our rhino, our wildlife and our planet,” he explains. “We need to protect these gentle giants.”

What does it take to keep a wild rhino alive in South Africa? There is no short or easy answer to that question. There may not even be a right one. The custodians of our beloved tubby grey icons have been thrust into an ever-changing war without rules, forced to trial and evaluate different strategies as they go along.

What we do know is that it takes money - lots of it. Did you know that in the Greater Kruger (including Kruger National Park), a minimum of ZAR 1.1 billion (US$ 61 million) was spent protecting rhino from 2017-2021? This figure was taken from a brand-new report:

“Evaluating the cost and effectiveness of rhino conservation interventions in the Greater Kruger”.

Compiled by a cross-disciplinary team of scientists and reserve managers, the 17-page report delves into the successes and failures of various interventions, including camera technologies, K9 units, dehorning and so on. This monumental project is of profound importance and offers an eye-opening glimpse into the complexities of rhino conservation. It is well worth a read!

WORLD RHINO DAY

‘Good news’ for rhinos as Africa defies poaching crisis to boost populations

By Tiara Walters | 21 Sep 2023

‘We can take a sigh of relief for the first time in a decade,’ declares leading conservation group on World Rhino Day, but urges caution.
__________________________________________________________________________________________________________________
Reversing a decade of decline, Africa’s rhino population has risen amid the poaching crisis, according to an announcement by the IUCN African Rhino Specialist Group (AfRSG), which has combined rhino data from range states to produce a continent-wide tally.

Marking World Rhino Day on Friday 22 September, the group said that Africa’s rhino population had grown by 5.2% by the end of 2022, reaching 23,290 animals.

White rhinos, the larger and more docile of the two African species, had achieved something of a milestone, attaining their first increase in the decade since 2012.

Now at more than 16,800, the continent’s white rhino population had increased by 5.6%.

A boost in critically endangered black rhinos had taken their numbers to nearly 6,500, thanks to “a combination of protection and biological management initiatives”, said the group. That is an encouraging 4.2% rise from the previous year.

Also in 2022, Kenya’s official records indicated a decline in rhino poaching, with just one incident compared with six in the previous year.

“With this good news, we can take a sigh of relief for the first time in a decade,” said Dr Michael Knight, AfRSG chair.

High losses for South Africa, Namibia

“Rhinos have significant ecological value to wild spaces,” Rhino Recovery Fund director Dr Markus Hofmeyr, taking part in a World Rhino Day online event, said alongside other experts. These horned eco-engineers create grazing areas for other species, facilitate soil nutrient cycling and bolster tourism-driven economies.

Still, in the same year, Namibia “detected 93 poached rhinos … compared [with] 47 the previous year”, according to the group.

More than 550 rhinos were killed illegally across the continent — but it was the population in South Africa that was hardest hit by far, yielding a notable loss of 438 animals in 2022, the group reported.

The South African government’s latest national poaching data from the first half of 2023 indicated that 231 of these animals were slaughtered within the country’s borders during this time — with a transition in the killing fields to KwaZulu-Natal.

Regardless of ongoing challenges in South Africa to secure the national herd, which remains the stronghold of the world’s rhinos, the AfRSG announcement is undoubtedly good news.

Hope springs elsewhere

The announcement is buoyed by yet another new development that has recently helped reinvigorate hope for the entire African herd: a landmark acquisition by the Johannesburg-based African Parks conservation NGO of about 2,000 southern white rhinos in the country’s North West.

Formerly owned and managed by private rhino rancher John Hume on his Platinum Rhino farm, the animals will now be rewilded into safe zones over the next decade, the group announced in early September.

“The scale of this undertaking is simply enormous, and therefore daunting. However, it is equally one of the most exciting and globally strategic conservation opportunities,” said African Parks CEO Peter Fearnhead. “We will be working with multiple governments, funding partners and conservation organisations, who are committed to making this rewilding vision a reality.”

Potential setbacks aside, the African Parks population is expected to fan out into a contingent of up to 3,000 over the next decade.

As reported by Daily Maverick’s Tony Carnie, conservation groups are planning to move 300 animals a year. Groups in at least four African states — Namibia, Zimbabwe, Zambia and Kenya — have offered rewilding zones, Carnie reports.

Think, well, small

Knight’s assessment of the overall 2022 increase in rhino numbers remained conservative: “It is imperative to further consolidate and build upon this positive development.”

Yet, it is equally imperative, the AfRSG chair added, “not to drop our guard”.

Dr Sam Ferreira, AfRSG scientific officer, told Daily Maverick that, “while we celebrate the trends in African rhinos, we should remain vigilant and carry concerns for some of the Asian rhino species”. Populations on the Asian continent continued to be critically endangered.

Ferreira said the “successes come from hard work of rangers and authorities but also have important lessons”.

Also a large mammal ecologist with South African National Parks, Ferreira urged the need to make rhinos relevant to communities: “Let the locals lead and ensure problems and solutions are debated and decided at the local level.”

He stressed the value of “trustworthy partners — including governments that help with regulatory power” and “private industry and non-government organisations that provide operational nimbleness”.

Advocating the need to think small, Ferreira advised: “Don’t go too big because smaller areas allow operational situational awareness, easy ways to have credible and proud staff with integrity and detailed knowledge of rhinos at individual levels.” DM

Good news! \O

Not too sure about Ferreira's comments, though... O**

Rhinos can’t sweat, making them vulnerable to overheating: global warming could wipe them out in southern Africa

Southern Africa is home to 22,137 of the world’s 23,432 white and black African rhinos. But they’re facing grave threats because of a warming planet. Now, the first study of how climate change affects rhinos in southern Africa has found that they will cease to exist in the region’s national parks by 2085 if the world takes the worst-case scenario climate change pathway. Timothy Randhir, who has been an ecological economist for 47 years, explains what governments and parks can do to prevent this from happening.

Why are rhinos in danger of being wiped out?
Rhinos cannot sweat. If they want to cool their large bodies down in the heat, they need to consume a lot of water. They also rely on wallowing in water holes and resting in the shade. As Earth heats up, rhinos will only survive if they have more opportunities to cool down.

How did you calculate that rhinos will not survive the worst scenario?
We looked back in history to see how rhinos lived in southern Africa, and in one park in Kenya. We looked at the temperature and rainfall averages in each of the best locations for rhinos, and then we mapped out the extremes. This defined the climatic domain and gave us a macroecological perspective (where we do not look at one specific site but look at the larger picture of how temperature and rain influence the behaviour of rhinos).

Our conclusion was that if the world enters the 8.5 Representative Concentration Pathway, there is zero probability of rhinos surviving in southern Africa.

Is there a Plan B to avoid the worst for rhinos?
Yes. Our view is that governments and societies should start planning immediately to ward off the worst-case scenario. They have to actively start adding some resilience into the system.

In 2085, it is likely that the national parks will still exist. But the parks will need to start now to be sure that they’ve built in many new water sources so that the rhinos can cool off at much more frequent intervals.

The parks will also need to establish undisturbed tree cover: large patches of trees with no moving traffic or crop harvesting nearby. Those are important cooling off areas. The national parks must add patches of tree cover that are deliberately planned so that in the rhinos’ home range, they do not need to walk further and further to find shade to cool down in.

For rhinos to survive this climate change scenario, corridors will also need to be set up for rhinos to move between parks. Human settlements around national parks are becoming a huge stressor for rhinos because of poaching and also because they reduce the freedom of movement for rhinos. This will be very challenging for the parks and they must start planning their landscapes now.

How much will all this cost?
The costs will be a huge problem. Most parks are already stressed for funding. Parks have been trying to be creative in generating funds through eco-tourism and strategic elements of trophy hunting, but they have to be careful because some of the revenue-generating elements can add more stress to the system.

This study is a call for governments and people to protect and invest in these national parks and not just use them as an economic activity. One of the ideas is that when you protect a species like rhinos, elephants and gorillas, the investment you make in that species will help multiple species. The whole system will be protected because of that.

Until recently, our mindset about rhinos was about how they benefit us by bringing in revenues. That mindset has to change. We have to start looking at rhinos as an essential part of an ecosystem that is providing services to society. Having an ecosystem mindset in how we value things becomes important for our survival.

2085 isn’t far away. Could it really be over for rhinos by then?
In my work on watershed management, ecohydrology, complex systems, water resources, water quality, ecological economics and sustainability, I have mapped such scenarios all over the world. Researcher Hlelowenkhosi S. Mamba and I investigated what would happen if conditions in southern Africa reached those mapped by the Intergovernmental Panel on Climate Change’s Representative Concentration Pathways. These pathways are the global standard for predicting how the climate will change based on the actions of humans. We chose to map the future of rhinos based on the 4.5 and 8.5 Representative Concentration Pathways.

The 4.5 Representative Concentration Pathway simply means that the amount of carbon dioxide in the atmosphere will rise from 410 parts per million (ppm) now to 650ppm by 2100. This will warm the climate on the planet by an average of 2.4°C (between 1.7 and 3.2 degrees celsius) by 2100. But Earth will only get onto this pathway if we manage to cut methane gas and carbon dioxide emissions. This will only happen if methane gas emissions stop increasing by 2050 and we also manage to reduce the amount of carbon dioxide we pump into the atmosphere by 2045. By 2100, carbon dioxide emissions would also need to drop by half the level reached in 2050. Southern Africa’s rhinos can survive this, although many other plants and animals cannot.

The 8.5 Representative Concentration Pathway is the worst-case scenario that we can currently predict. In this scenario, Earth’s population will increase dramatically and we will continue to burn as much coal as we do now. We will fail to reduce greenhouse gases and global warming will continue to increase this century. This will deliver a temperature increase in the world of 4.3°C by 2100.
