Family: Podocarpaceae

High Risk Traits:

• Broad climate suitability (elevation 10-3000m; wide rainfall/temp range)
  
• Native or naturalized in tropical/subtropical regions
  
• History of repeated introductions outside native range
  
• Shade tolerant (at some life stage)
  
• Tolerates wide range of soil conditions
  
• Produces viable seed
  
• Self-compatible (wind-pollinated, out-crossing possible)
  
• Bird-dispersed propagules
  
• Propagules survive passage through gut
  
• Forms persistent propagule bank (germination delayed ~1 year)
  
• Tolerates mutilation/cultivation (responds to trimming)

Low Risk Traits:

• No evidence of weediness (gardening, agricultural, environmental, or congeneric)
  
• No spines, thorns, or burrs
  
• Not toxic to animals or humans
  
• Not a fire hazard
  
• Does not form dense thickets
  
• No vegetative fragmentation
  
• Minimal generative time ~4+ years (slow to mature)
  
• Propagules not wind-dispersed, water-dispersed, or externally carried by animals
  
• No prolific seed production (>1000/m²)
