Opuntioid cacti: declared pests

 

Velvet Tree Pear is in Goomalling!

  • One plant in a garden has become hundreds of plants on multiple blocks on the edge of Goomalling. (Approximately 90ha infested).
  • The infestation has reached the creek, which is part of the Avon-Mortlock catchment.
  • If left unchecked it will continue to spread further down the catchment.
  • Many more infestations are now appearing, mainly due to the planting of cacti in gardens throughout the Shire.

 

Why is it a concern?

  • The plant is hardy
  • Infestation spreads fast through seeds and pads. Seedlings are hard to detect
  • Animal vector of spread is unknown
  • Infestation has reached waterways and farmland

Case Study

Mature cacti (picture 1) is a result of a seedling left unmanaged, from this plant hundreds of seedling have procreated (picture 2).

Shire of Goomalling removed the cactus in 2015 which required 8 hrs backhoe to dig an adequate disposal pit and manually removed the cactus, 2 hr to mulch the site and spray the remnant seedlings. Estimate cost of removal for one plant is $600

Action Plan – PROJECT PRICKLE

 

Shire of Goomalling, Greening Australia and Department of Agriculture and Food WA are working together to eradicate the weed and increase awareness in the community about the significance of the problem.

 

Shire of Goomalling was successful in securing $20,000 towards cactus control in Goomalling. The main outcomes of the project:

  • Increase community awareness
  • Mapping of cactus locations
  • Identify animals eating the fruit and the spread of the seeds
  • Test methods of destruction including pad/stem injection of chemical and manual handling
  • Thorough data recording to inform DAFWA and other communities of effective control methods and management
