This latest infestation is the first to be discovered in this area, and is of great concern. <br></p> | <span><p>The City was first notified of a possible infested tree in Alphen yesterday, 18 April 2024. </p><p>'The City immediately deployed a team of monitors from our Invasive Species Unit to assess the area and to verify the reported infestation. Unfortunately, we can confirm that the Boxelder is indeed infested with PSHB.</p><p>'At this point in time, we cannot confirm the number of infested trees in the Alphen area as surveys are underway. I am urging all private land owners in Alphen and Constantia to please inspect the trees on their properties for symptoms and to contact us immediately should any of these be visible on any trees,' said the City's Deputy Mayor and Mayoral Committee Member for Spatial Planning and Environment, Alderman Eddie Andrews.<br></p>

Thus, I ask residents to please give the teams access to their properties so that we can determine the extent of the PSHB infestation.

However, the response time will depend on the number of sightings reported.</p><p> </p><p>The PSHB poses a serious threat to Cape Town's urban forest as infested trees have to be chipped. </p><p> </p><p>Importantly, the use of pesticides and fungicides have not proven effective at eradicating PSHB from infected trees. The PSHB beetle can easily spread across suburbs if extra precaution is not taken. Apart from infected wood, the beetle can also spread through clothing, vehicle crevices, or unclean horticultural equipment.</p><p> </p><p>'We are also encouraging residents to attend any of the free training sessions offered by the City of Cape Town, especially if you have trees on your private property. The knowledge is useful and will empower property owners to take care of their gardens in a safe and responsible manner,' said Alderman Andrews.</p><p> </p><p><strong>End</strong></p><p><strong> </strong></p><p><br></p> | 2024-04-18T22:00:00Z | GP0|#1d539e44-7c8c-4646-887d-386dc1d95d70;L0|#01d539e44-7c8c-4646-887d-386dc1d95d70|City news;GTSet|#62efe227-07aa-45e7-944c-ceebacca891d | | | | | GP0|#bd5841d6-02a3-433d-ac6e-e80a4f2f7ee3;L0|#0bd5841d6-02a3-433d-ac6e-e80a4f2f7ee3|Tree maintenance procedures;GTSet|#2e3de6c1-9951-4747-8f53-470629a399bb;GP0|#5ddbe605-1355-4391-9598-bd9534f9f179;L0|#05ddbe605-1355-4391-9598-bd9534f9f179|Invasive Alien Species;GTSet|#2e3de6c1-9951-4747-8f53-470629a399bb | 1 | | | | | | | | | | | 0 |
