After writing about the deterioration of Kirstenbosch Botanical Gardens, we published a list of questions and possible solutions. As we expected, no answers were forthcoming from the South African National Biodiversity Institute (Sanbi) other than an email requesting alterations and retractions. But, following our articles [here & here] and a probe by Carte Blanche, alarm bells began ringing.

What followed will have come as an unwelcome surprise to Sanbi, which administers the gardens.

Acting on a letter from a concerned Cape Town resident to Parliamentâs Portfolio Committee on Forestry, Fisheries and Environment, it was hauled before Parliament to answer tough questions from well-informed MPs.

The committee subsequently required Sanbi to provide written responses by 1 September.

The trigger

Our investigation was triggered by plant specialist and long-time volunteer James Deacon. In a widely shared Facebook post, he wrote that Kirstenbosch was no longer a place that brought him joy, but âpain and sadnessâ.

Walking through the nursery with us, he said, he saw âneglect, decay and deathâ. Collections built over decades were slowly dying, the Protea collection was less than a third of what it had been and only a fraction of the Ericas remained.

Great plantsmen and women, he told us, had left before they should have because working there had become unpleasant and because procurement made their jobs almost impossible. He said Kirstenbosch no longer had a Protea or Erica expert, that staff morale was low and that the garden could not reliably produce durable metal labels for plants.

He said living collections were in decline and many of the thousands of valuable and rare succulents confiscated from plant poachers were deteriorating.

MPs wanted answers

On Tuesday, 11 August, members of the Portfolio Committee used question time to grill Sanbi on a range of concerning issues.

Aware of intense public scrutiny, it put on a brave face, with Sanbiâs board chairperson, Dr Mmaphaka Tau, conceding that public interest in the garden was âboth understandable and legitimateâ.

In its proposed programme, general manager of National Botanical Gardens, Christopher Willis, wanted MPs to realise that the gardens, formed in 1913, remain internationally recognised with high levels of arboretum accreditation.

However, he said, a further R150-million was needed for outstanding work which included nursery upgrades, completion of its seed bank, signage, irrigation and building repairs.

Following media and other criticism, he said the administration had created Kirstenbosch Operation Excellence to fill critical vacancies, restore horticultural expertise with the help of retired horticulturalists, fast-track procurement, upgrade nurseries and establish monitoring and evaluation.

Evidence, not a âmanagement planâ

But DA MP Andrew de Blocq made clear that Parliament wanted evidence rather than another management plan.

âKirstenbosch is a place that I basically grew up in. I know it very, very well, I care for it very deeply, and I want to see it succeed,â he said. He had visited several times this year and believed it remained âa wonderful place for tourists to visitâ.

But he challenged Sanbiâs description of a range of initiatives, saying that his observations suggested that they were no longer operating, or were operating at a substantially reduced level. The plant fair had not been held since 2023, golf-cart tours had stopped, seed transfers had largely ceased, the public seed room had closed, seeds were no longer distributed to Botanical Society members and Kirstenbosch no longer produced its Index Seminum, the catalogue used to exchange seed with other botanical gardens.

He also challenged Sanbiâs account of plant records, labels and pest control, saying that horticulturists described the accession system as âclumsy and uncoordinatedâ and procurement had failed to supply appropriate biological controls.

About funds

The money question was unavoidable. Kirstenbosch drew about 788,000 visitors and generated roughly R142-million in the latest financial year, most of it from admission fees, leading de Blocq to ask how much returned to the garden under Sanbiâs centralised, cross-subsidising model. âYou cannot kill the golden goose because itâll stop laying eggs,â he said.

The gardenâs conservation machinery drew sharper questions â de Blocq asked why the nursery-manager post had been vacant for eight years, a soil steam steriliser had failed for 10, heating benches, fogging and misting systems for seven, and nursery climate control for eight.

He asked about claims that conservation stock beds had become overgrown and critically endangered plants had died, while only a small percentage of the former Erica collection remained.

Earlier warnings echoed

These questions closely echoed warnings from James Deacon and other plant specialists we interviewed for earlier reports: that plants cannot wait for slow procurement, that provenance is lost when records and labels fail and that an extinct-in-the-wild species can disappear entirely if its last cultivated material is neglected.

Willis replied that a contractor had been appointed for nursery upgrades, a Protea specialist would start in September and the long-vacant nursery-manager position was being prioritised.

On the confiscated succulents crowding Kirstenbosch and other gardens, de Blocq was especially forceful. Sanbi put the total at nearly 1.3 million plants and conceded that the influx had strained space, staff and operations. Its national response strategy requires R70-million over five years and, a Sanbi official told MPs, âremains largely unfundedâ.

Some estimates suggested only about 100,000 plants remained alive after more than a million accessions, added de Blocq. They were being kept in suboptimal conditions, he said, without sufficient separation to prevent cross-pollination and the loss of genetic provenance.

âOn the succulents, is really where my heart starts to break,â he said, âThey simply donât have the space.â He added that the confiscated plant collection is currently at risk following the dismissal of key staff.

ANC MP Nkhensani Bilankulu asked about the funding gap for the succulent response, while committee member Leseletsi Mokoena asked what immediate funding the department and Treasury would provide.

Sanbi replied that it was approaching donors and had submitted a proposal linked to the Global Environment Facility, but the fiscus had largely been unable to fund the strategy.

Other MPs broadened the pressure. EFFâs Dr Lilian Managa asked when vacant posts would be filled and how infrastructure would be maintained across its full life cycle. PA Member Sheila Peters demanded measurable evidence to confirm or refute a five-year decline in Protea and Erica collections, as well as figures showing changes in horticultural staffing, vacancies and budgets.

The BotSoc problem

Returning to the damaged relationship with volunteers and the Botanical Society, de Blocq asked how Sanbi would rebuild the capacity and public goodwill lost when access arrangements changed under instruction from former Minister Barbara Creecy.

Sanbi replied that it had 102 Kirstenbosch volunteers and was revising its policy to offer benefits benchmarked internationally.

One potentially serious financial question remained unanswered â de Blocq asked Sanbi what had happened to a large ring-fenced conservation account, citing information he had received suggesting that funds had been used to pay salaries: âWhere did that money go and who authorised the draining of the conservation account?â

The focus now must be on implementation, he said. âParliament must continue to hold Sanbi to account for delivering the improvements it has identified, while ensuring that Kirstenbosch receives the support it needs to remain one of South Africaâs flagship botanical and conservation institutions.â

At the end of the hearing, he noted that Sanbi had not answered the conservation account question or his equipment-specific questions, and requested written replies. The committee set 1 September as the deadline.

Sanbi acknowledged that there were problems. But Parliament wants proof that the rescue has begun.
