Trees slated to go

Central Otago Mirror - - CLASSIFIEDS -

An ar­borist has rec­om­mended felling four 100-yearold trees in a lake­side park in Queen­stown and the staged re­moval of the re­main­ing 30-me­tre high poplars. A ma­ture Lom­bardy po­plar was felled by high winds on Jan­uary 17, crush­ing a car parked on Lake Es­planade, dam­ag­ing other ve­hi­cles and de­stroy­ing a cor­ner of the Lake­side Mo­tel. A risk as­sess­ment was car­ried out on all the her­itage poplars in St Omer Park by Auck­land-based ar­borist Sa­muel Earp, of Green­sceneNZ. His re­port said the fallen po­plar snapped at the base and parts of the base were hol­low and sub­ject to white rot. There were lit­tle out­wardly vis­i­ble indi­ca­tions that the tree was af­flicted with rot be­fore it fell, the re­port said. Twenty-six poplars re­main in the park and Mr Earp’s as­sess­ment used a vis­ual tree anal­y­sis and a re­sis­to­graph, a de­vice that drives a fine drill into wood and mea­sures re­sis­tance to de­tect struc­tural in­tegrity. Visu­ally, all trees were in gen­er­ally good health but the re­sis­to­graph de­tected pock­ets of de­cay and hol­lows in al­most all spec­i­mens. Four black poplars at the western end of the park were in gen­er­ally good health and there were no ma­jor con­cerns re­gard­ing struc­tural in­tegrity. Four Lom­bardy trees should be re­moved and the re­main­ing trees’ crowns chopped back by one third to min­imise risk. The re­port rec­om­mended a staged re­moval of the re­main­ing trees and re­plant­ing. ‘‘The po­ten­tial per­sons and/or risk to prop­erty from part or whole Lom­bardy po­plar tree fail­ure is of con­cern due to the fre­quent use of St Omer Park, Lake Es­planade and ad­join­ing build­ings and struc­tures.’’ An­nual in­spec­tions of re­main­ing trees and a re­place­ment plant­ing pro­gramme us­ing more ro­bust, longer-lived species were also rec­om­mended.
