Spike Moss
Spike Moss (Selaginella spp.) is a problematic weed known for its invasive tendencies in various regions. Also referred to as spikemoss or clubmoss, this plant’s ability to spread rapidly and form dense mats on the ground can have detrimental effects on native ecosystems. While it may look visually appealing in some landscapes, its aggressive growth and lack of natural predators outside its native range make it a challenging weed to control. Understanding its ecological impact and implementing appropriate management strategies is crucial to prevent further spread and protect the balance of native flora and fauna.

Common Names:
Spike Moss is also known as Spikemoss or Clubmoss.
Areas where it is Typically Found:
Spike Moss is commonly found in moist, shaded areas with rich organic soil. It thrives in both natural environments, such as forests, woodlands, and swamps, as well as in disturbed habitats like gardens, lawns, and urban areas.
Ecological Impact:
Spike Moss is an aggressive weed that forms dense mats on the ground, outcompeting native vegetation for resources such as water, light, and nutrients. This can lead to a decline in native plant species and affect the habitat and food sources of native animals and insects. The invasive nature of Spike Moss can disrupt the ecological balance and reduce biodiversity in affected areas.
Identification:
- Leaves: Spike Moss has small, scale-like leaves that are arranged in a spiral pattern along the stems. The leaves are usually green but can vary in color depending on the species.
- Stems: The stems of Spike Moss are prostrate and branched, forming dense mats on the ground.
- Flowers: Spike Moss does not produce true flowers. Instead, it reproduces through spores.
- Fruits: The spores are produced in cone-like structures called sporophylls.
- Roots/Rhizomes: It spreads through creeping rhizomes that help it colonize new areas.
- Growth Habit: Spike Moss has a low-growing and creeping growth habit.
Changes through the Four Seasons:
- Spring: In spring, Spike Moss starts actively growing and producing new stems and leaves.
- Summer: During the summer, it continues to spread rapidly and cover the ground.
- Autumn: In autumn, Spike Moss may slow down its growth.
- Winter: In colder regions, it may become semi-dormant.
Treatment & Removal:
Organic Methods: Hand-pulling can be effective for small infestations, but it is essential to remove all plant parts, including rhizomes, to prevent regrowth.
Mechanical Methods: Cutting or mowing can help control its spread, but repeated treatments are necessary to exhaust its energy reserves.
Biological Methods: Some animals and insects may feed on Spike Moss, but they are not widely used for control.
Chemical Methods: Herbicides can be used, but they should be applied carefully to avoid harming desirable plants.
On-Going Management & Control:
Regular monitoring and early detection of Spike Moss are essential for effective management. Preventing its introduction to new areas and controlling its spread through various methods can help protect native ecosystems from its invasive nature.
Conclusion:
Spike Moss (Selaginella spp.) is a problematic weed with invasive tendencies that can disrupt the balance of native ecosystems. By understanding its impact and employing appropriate management techniques, we can mitigate its spread and preserve the biodiversity of our natural habitats. Heightened awareness and responsible management practices are vital to prevent further encroachment of this challenging weed in our environment.
