What Is a Self-Seeded Tree and Why Should You Remove Them?

Jan 22, 2025

Self-seeded trees, also known as volunteer trees, are trees that grow without being intentionally planted. They often sprout from seeds dispersed by wind, birds, animals, or even human activity. While some self-seeded trees can add natural charm to a garden, others can become invasive and problematic, particularly in urban environments like the Gold Coast. That’s why tree removal for self-seeded trees may be necessary.

How Do Self-Seeded Trees Spread?

Self-seeded trees typically spread through natural dispersal methods, such as:

  • Wind: Seeds are carried by the wind and land in various locations.
  • Animals and Birds: Seeds are eaten and later dispersed through droppings.
  • Water: Seeds are transported via waterways.
  • Human Activity: Seeds may hitch a ride on clothing, vehicles, or gardening tools.

While this natural process can lead to the growth of trees in unexpected places, not all self-seeded trees are beneficial to the environment or your property.

Why Aren’t Self-Seeded Trees Good to Keep?

Self-seeded trees often grow in unsuitable locations, such as near buildings, fences, or other structures. Left unchecked, they can:

  • Compete with desired plants for nutrients, water, and sunlight.
  • Damage property with invasive root systems.
  • Attract pests or create mess with excessive leaf or fruit drop.
  • Disrupt ecosystems by outcompeting native vegetation.

For these reasons, it is often best to have tree removal for self-seeded trees, especially those considered invasive or pest species. Below are some common self-seeded trees on the Gold Coast that you should be aware of.

Four Problematic Self-Seeded Tree Species on the Gold Coast

1. Cadaghi (Corymbia torelliana)

  • Characteristics: This fast-growing tree has smooth bark and produces clusters of cream-coloured flowers. It is often found in gardens and urban areas.
  • How It Spreads: Cadaghi trees spread through wind-dispersed seeds and are highly attractive to bees, which help propagate them.
  • Why Remove It: The tree is considered invasive as it outcompetes native species. Its dense canopy and aggressive growth can overshadow other plants, reducing biodiversity.

2. Slash Pine (Pinus elliottii)

  • Characteristics: A tall conifer with long needles and cones, the Slash Pine was originally planted for timber but has become invasive in urban and natural areas.
  • How It Spreads: The tree spreads through wind-blown seeds that germinate easily in disturbed soil.
  • Why Remove It: Slash Pine disrupts local ecosystems and is a fire hazard due to its resinous wood and fallen needles.

3. Umbrella Tree (Schefflera actinophylla)

  • Characteristics: Recognizable by its umbrella-like clusters of leaves and bright red flowers, this tree is a popular ornamental plant that has escaped cultivation.
  • How It Spreads: Birds and bats eat the fruit and disperse the seeds over large areas.
  • Why Remove It: The Umbrella Tree is highly invasive, often growing in unsuitable locations like retaining walls or near pipes, where its roots can cause significant damage.

4. Cocos Palm (Syagrus romanzoffiana)

  • Characteristics: This tropical palm has a single, smooth trunk and feathery fronds. It produces clusters of orange fruits that attract birds and bats.
  • How It Spreads: The fruits are consumed and spread by wildlife, leading to widespread germination.
  • Why Remove It: Cocos Palms are messy, dropping fruit, fronds, and flowers regularly. They are also considered a weed species that can choke out native plants.

Council Guidelines for Tree Removal for Self-Seeded Trees

The City of Gold Coast considers these species to be pests or weed trees. In most cases, they do not require council consent for tree removal for self-seeded trees. However, if you’re unsure about the identification or regulations surrounding these trees, it’s best to consult a professional.
