Weed Tree Removal

One of the key objectives and underlying principles of the club’s Landscape Master Plan (LMP) is to work towards re-establishment of appropriate species of natural vegetation in out-of-play areas. Since 2012 we have planted over 10,000 native species, with a relatively good survival rate.

These areas play an important role and contribution to landscape health by providing the correct site plant species and habitat associations, and therefore positive benefits to local biodiversity.

In the local context of the course itself, weed species removal approach and revegetation initiative encourages the creation of the correct ecosystems. In particular provision of rich habitat for encouragement of diverse populations of local birds, fauna, reptile, aquatic and insect species, which in turn promotes an ecosystem with appropriately integrated function and therefore :

  • natural resilience, low water demand and sustainability,
  • improved water quality, healthier waterways and riparian habitat
  • improved visual amenity and enjoyment of the course and healthy landscape experience for Club members

In terms of weed tree species found at the Club, there are 7 other main weeds trees species (amongst many), including Cadaghi’s, Tipuanas, Fiddlewoods, Pepper trees, Coral trees, Chinese Elms and Camphor Laurels – all to some degree species which also have detrimental effects to course landscape health.

Several years ago, the club started a staged removal of many of the weed trees around the course. This process consisted of selectively removing trees and providing native succession planting to those areas. We have now reached a point where the native plants are established enough to remove more weed trees , which his will provide much need light and nutrients for the natives trees to continue to thrive whilst still maintaining the integrity of the treeline. IN December this year we will be completing some removal works on 10, 14, 16 and 18. The main species of tree being removed are Cadaghi (Eucalyptus torelliana).

According to (Weeds.brisbane.qld.gov.au, 2019)

  • The Cadaghi (a North Qld rainforest tree) are a declared weed species regarded as environmental weed trees on BCC lists, and all other local govt areas in south east Qld.
  • Its becoming a serious weed in Queensland as its seeds are spread into surrounding forests, woodlands and waterways by bees and birds, water and wind, and then as a dense canopied tree (often covered with black sooty mould) it continually spreads and shades out and prevents healthy understory of local native species plants  – therefore significantly impacting the optimal diversity and habitat of naturally occurring vegetation communities.
  • The Club’s declaration is to reduce populations of Cadaghi

It needs to be noted that the ongoing selective and progressive removal of Cadaghis and other weed tree species is being done in a well-considered, responsible and measured manner. We are mindful of members perceptions of the gaps and opening left by large tree removal, and in most cases there has been advance succession planting of local native species allowed to become reasonably established before trees are taken out. We also note that the green waste generated through weed tree removal is being re-used for benefit as site mulch around the course.

Through the combined result of weed tree removal and natural revegetation, there has been substantial progress achieved species as part of the ongoing LMP program to date.

Local bird groups observations have identified an increase in the variety of bird species on the course and this is a key indicator and measurement of the success to date of the LMP initiatives implemented already and improved biodiversity created – within a relatively short timeframe.

The committee and management believe that it is the BGC’s corporate, community and moral responsibility to remove weeds and enhance the environment. The work that has been completed over the years is in line with the latest global Geo Certified thinking and “Sustainable Golf Development” guidelines and manual documents to “Creating a positive legacy” for the future generations to enjoy our club as we do (Sustainable.golf, 2019).
