JOHANNESBURG City Parks is undertaking a pruning programme ahead of winter because of increasing problems caused by fallen branches, ranging from damaged power lines to property destruction.
"While the pruning might look quite severe, it is necessary," said Jenny Moodley, spokesperson for City Parks. "Residents are urged to support the pruning programmes, which are undertaken every four years."
As a metro agency, City Parks is in charge of the city's green spaces and for maintaining more than 1,6 million street trees. It has a duty to ensure proper and regular maintenance of the trees, under the Occupational Health and Safety Act.
Qualified horticulturists oversee the regular pruning programmes, which are determined by the number of complaints and requests for tree pruning from residents, which can be made through the Joburg Connect Call Centre.
"The decision to prune trees is further informed by suburbs that have the potential or have recently experienced power outages caused by trees entangled in power lines, roots that have entered the stormwater system or trees that have the added risk of endangering life and property," Moodley added.
Some species of trees, especially ashes and elms, will need additional pruning over the next four years as they easily reach their natural heights. Depending on the species, fully grown elms can reach anywhere between 20 and 40 metres. Adult ash trees can grow to similar heights.
City Parks gets numerous requests over the winter months from residents, with some believing that trees must be pruned or removed because they obstruct sunlight. That is untrue, however. There is great value in street trees adjacent to houses and obstructing the sunlight does not warrant a tree's removal.
"It is our collective responsibility to ensure that we live in a healthy city and it is City Park's responsibility to ensure that the appropriate greening maintenance levels are retained, to develop the basis for a healthy city," Moodley concluded.
Suburbs where trees will be pruned during March include Robindale, Robinhills, Blairgowrie and Kenilworth.
