Interaction riskLow
- Low

- High
- Very high
- Why interaction risk is low
- Sharp trunk and stalk spines can puncture skin; view fronds without touching or climbing the fern.

- Crown: Look for a broad umbrella of long divided fronds atop one trunk.
- Spines: Inspect the armored trunk and stalks visually without testing them by touch.
- Spores: Leave fertile fronds and the moist root mantle intact.
