Many sources of land-based pollution

PowerPoint Presentation: 

Models estimate that 22% of all coral reefs world-wide are at high or medium threat from inland pollution and soil erosion. (Bryant et al. 1998). USGS Runoff threatens coral reefs globally

Runoff impacts growth & survival of hard coral colonies:

Any idea’s how runoff impacts coral growth and survival?: 

Any idea’s how runoff impacts coral growth and survival? Two volunteers? 1. 2.

Sediments reduce light and decrease coral growth : 

Sediments reduce light and decrease coral growth

Sediments smother coral & sloughing wastes energy Photo’s courtesy of Bill Walsh

PowerPoint Presentation: 

Runoff effects coral reproduction & recruitment Coral settlement rates are near zero on sediment covered surfaces Sediment tolerance is lower in new recruits

Runoff effects reef community structure:

Managing land-based pollution: 

Managing land-based pollution US Coral Reef Task Force formed Addressing key threats to reefs is a national priority Development of local action strategies More information: http://coralreef.gov

PowerPoint Presentation: 

Hawaii’s Local Action Strategy: A collaborative multi-agency and community approach to protect Hawaii’s coral reefs Sustainable Living Institute of Maui

Taking action to:: 

Taking action to: Reduce pollutant loads Increase understanding through scientific research & monitoring Increase awareness
