A simple environmental weed prioritising system. What to deal with first. What's a waste of effort
Weed prioritisation for efficient and effective ecosystem restoration
Sweet Pittosporum - Pittosporum undulatum
Classifying environmental weeds according to their invasive aspects, impacts and abundance and their individual biology is absolutely essential to proceeding in a systematic and efficient manner. Adapting and refining the priorities to seasonal and site specific conditions and actual outcomes over time is also essential
KEYSTONE - K
Species that totally dominate structurally and floristically/old populations that have reached the peak of their invasion potential in a given area
·
Many species (flora and fauna) may have become dependent
Work slowly and systematically from retention areas outwards
Remove mature specimens first
Keep in mind that these plants could be habitat for something
May be useful as buffers to other weed invasion
SMALL PATCHES - S
Of variable risk, but easiest to eliminate
· S1 - High risk = High priority
Eliminate across the site. Those that genetically pollute
and therefore threaten the underlying integrity of the system and those weeds that are extremely difficult to eradicate once
established. Target seeding individuals first. Get seed off the site
· S2 - Moderate risk = Moderate priority
Eliminate from retention (highest quality) areas first
· S3 - Negligible risk = lowest priority
Don't worry about them too much. There'll be more important tasks
UBIQUITOUS SPECIES - U
Scattered weeds of disturbed areas
Hard to eliminate. These are often non-bully annuals
Look at management regime/disturbance factors
· Eliminate in retention areas but of low priority elsewhere
