Cooperation safeguards biosecurity on Kangaroo Island

Active Tree Services has sought to work with Natural Resources Kangaroo Island (NRKI) and SA Power Networks to ensure their biosecurity responsibilities are up to scratch.

The mainland based company is contracted to carry out various tree trimming activities across Kangaroo Island, including power lines across farm land. 

Biosecurity Liaison Officer at NRKI, Andrew Triggs said that both SA Power Networks and companies such as Active Tree Services had actively sought him out to ensure that best practice is observed with all matters relating to biosecurity.

“‘It is really encouraging that private companies are taking a proactive approach to protecting KI and that they share the responsibility for biosecurity protection," Mr Triggs said.

“It is really important, that everyone understands how they can contribute to this effort and Active Tree Services recognise that they could bring in weeds, plant disease, soil or insects that could adversely impact on KI and that they are doing something to reduce the risk.”

As part of their standard operating procedures, Active Tree Services undertake an array of proactive measures in order to reduce their biosecurity risk including:

  • cleaning, inspection and disinfection of equipment before loading on Cape Jervis ferry;
  • compliance with requirements of honey and potatoes as part of their provisions being brought to KI;
  • cleaning of vehicles between movements on KI, where required;
  • suitable disposal of mulch to ensure that even local species aren’t moved across KI;
  • reporting of unusual pest animals and plants; and
  • contacting the biosecurity liaison officer to inform them of their intentions prior to travel to KI.

Operations Manager for Active Tree Services, Nick Shelton said that the company recognised how important biosecurity was to KI.

“We understand that landholders may be worried that we might spread weeds, so we ensure that we do everything we can to clean our machinery and check it so we reduce the likelihood of causing problems,” Mr Shelton said.

This collaborative approach is shared by SA Power Networks, which also have biosecurity procedures in place for their own vehicles and personnel with documented procedures for checking vehicles and advising landholders of their intentions to service and maintain powerlines.

Environment and Sustainability Manager with SA Power Networks, Allison Purnell-Sullivan said; “We are always looking at how we can reduce our impact on the environment and having biosecurity procedures in place is a big step in reducing risk to both the environment and agricultural enterprises where our power lines traverse."
