Habitat and ecology
- Habitats
- Submerged vegetation; Marine
- Food and resource needs
- Primary production, nutrient uptake, detrital export, grazing and habitat provision.
- Reproduction
- System renewal through ecological recruitment, succession, hydrologic/sediment processes and/or active management where applicable.
- Shelter
- Turf/foliose/canopy algae over rock, reef, rubble or sediment.
Threats and conservation
- Threats
- Nutrient enrichment; invasive algae; herbivore depletion; warming; sedimentation; storms.
- Conservation actions
- Maintain water quality/herbivory; monitor native/invasive algae; control nuisance invasives where justified.
- Monitoring
- Monitor physical condition, community state, connectivity, pressures and system-specific indicators; preserve place/time/method/source context.
- Data gaps
- Current spatial extent, condition, quantitative thresholds and relationship magnitudes require continuing evidence integration.
Process and seasonal context
- Seasonal timing
- Year-round with event/seasonal dynamics where applicable
- Seasonal description
- Nearshore system where macroalgae form dominant cover/canopy and distinct habitat/food-web structure.
Place and watershed context
