The death of trees?

Indigenous and exotic trees in South Africa are dying by the thousands because of a tiny beetle that experts say is “impossible to eliminate”.

The beetle is only two millimetres in size and can be extremely difficult to spot.

The destructive polyphagous (able to feed on various kinds of foods) shot hole borer beetle has already infested thousands of trees and plants in the country and is expected to reach all corners of SA by 2022, killing off and damaging hundreds of species of trees. And while this happens, desperate calls to register chemicals to treat the trees have fallen on deaf ears.

Dolphin Coast shot hole borer infestation results alarming

Simbithi Eco Estate has been the leading force locally in the fight against the PSHB – a beetle that acts as the carrier of a fungus that infects and kills trees.

Kitted out with a near infrared camera, a drone was used to map out forested areas to identify the dreaded polyphagous shot hole borer (PSHB) – and the results were alarming.

Simbithi Eco Estate has been the leading force locally in the fight against the PSHB – a beetle that acts as the carrier of a fungus that infects and kills trees.

The Dolphin Coast was South Africa’s seventh confirmed site of infestation of the beetle which is believed to have come from South East Asia.

City Parks maintains that they will only remove dead trees and not living, highly-infested host trees #GazetteProtectOurTrees

JOBURG – Johannesburg City Parks and Zoo has responded to points made in a lecture from Professor Wilhelm de Beer.

This comes after Rosebank Killarney Gazette’s article How can we control the borer? [Week ending 19 April] stated that Professor Wilhelm de Beer of the Forestry and Agricultural Biotechnology Institute (Fabi) suggested that all highly-infested reproductive host trees should be removed.

Manager of urban forestry at Johannesburg City Parks and Zoo (JCPZ) Thabang Mokone stated that the entity has maintained this position due to: a lack of research data to support the claim that the removal of reproductive host trees is the best solution, the loss of biodiversity this will cause, a lack of funding, a lack of dedicated dumping sites and the aftermath of such deforestation.

iol.co.za – Fears over South-east Asian borer invading KZN trees

Fears over South-east Asian borer invading KZN trees

Durban – A destructive borer is eating away at indigenous and exotic trees in South Africa, across KZN’s various habitats from the Berg to the beach.

Durban environmental consultant Johan Bodenstein told the Independent on Saturday that the polyphagous shot hole borer, indigenous to south-east Asia, was being countered in the US using a chemical that is not registered in South Africa.

“People are taking their own initiative buying chemicals and experimenting,” he said.

capenature.co.za – Attack of the Shot-Hole Borer

Attack of the Shot-Hole Borer

The blog title may sound like something from the realm of science fiction but unfortunately the Shot-Hole Borer is a very real and present threat to trees in South Africa.

The Polyphagous Shot-Hole Borer (PSHB) is a beetle from Asia that has recently been discovered in South Africa. It has a destructive impact on living trees as it lays eggs inside branches and trunks, ultimately causing disease and death of the host. The beetle creates tunnels, deep within the tree, where it breeds. The female beetle carries a fungus which spreads outwards from the tunnels into the tree, blocking the tree’s vascular system. The tree branches begin to dry up, they lose their leaves and with time the tree may die.
