Threats and conservation
- Threats
- Management agent; host-specificity and historical release context should remain explicit
- Conservation actions
- Retain observations with provenance; protect sensitive sites; support specialist review; apply disease hygiene and management protocols when relevant
- Monitoring
- Record substrate, host, microhabitat, date, rainfall/moisture, visible morphology, photos, specimen/voucher status, DNA status, and attendant biota
- Data gaps
- Kauaʻi voucher status, precise taxonomic confirmation, microhabitat, host/substrate specificity, abundance, and seasonal pattern need expansion.
Process and seasonal context
- Seasonal timing
- Often moisture- and substrate-dependent; Kauaʻi timing requires repeated observation
- Seasonal description
