LaoLao Bay Road & Coastal Management Improvement Plan Pacific Islands Environment Conference Hagatna, Guam June 26, 2013
Why Laolao Bay? •Coral reefs valued at ~$34K •Rich marine ecosystem •Popular dive site •Recreation site •Turtle nesting habitat •Historical Sites •Pristine limestone forest
Restoration Goals • Reduce Runoff – Road and Drainage Improvement – Stream Crossing Repairs – Revegetation of Upper Watershed
• Increase Awareness – Community Outreach (e.g., social marketing campaign, signs, press releases, radio talk shows, commercials, print materials)
The Decline Coral size class distributions across Laolao based upon 1991 – 2012 comparison
Houk, et al., (2012)
Laolao Bay Timeline 1991 One acre in the Laolao Bay Watershed cleared under an Earthmoving and Erosion Control permit, for the purposes of constructing an access road – source of sedimentation 1991 Extensive dataset developed as part of the Laolao Bay golf course construction to evaluate the magnitude of negative change in Laolao Bay 1992 Historical surveys conducted in Laolao Bay that provided a robust set of baseline data on ecological assemblages 1997
Birth of the Marine Monitoring Team (MMT)
1998 Laolao Bay Watershed listed as a Category 1 watershed in the Unified Watershed Assessment though the full assessment was not completed. 1998 The DEQ Non Point Source Pollution Program along with the CNMI Watershed Group decide to collaborate in the effort to control NPS pollution the Laolao Bay Watershed area 2000 The Laolao Bay Sea Cucumber Sanctuary established by the DFW NonCommercial Fishing and Hunting Regulations

Laolao Bay Timeline 2003 Listed as a priority site for CNMI’s Coral Reef Protection Local Action Strategies 2005 A “Know Your Watershed” survey is carried out for the purpose of gathering a baseline assessment of the awareness of local residents in the Laolao Bay watershed 2006 Coral Economic Valuation Study 2006 Laolao was listed as a priority site for the Micronesia Challenge 2008 A socioeconomic study of Laolao users is completed as part of a SEM-Pasifika project to understand more about threats to the area and solutions from the users’ perspective 2009 Laolao Bay Conservation Action Plan (CAP) completed 2009 A $2.6 million grant is awarded through the American Recovery and Reinvestment Act (ARRA) to reduce erosion and sediment transfer from the Dandan/San Vicente side of Laolao Bay Drive through road and drainage improvements 2010 Laolao Bay listed as a Priority Watershed in the Commonwealth of the Northern Mariana Islands Coral Reef Management Priorities document

Our Laolao campaign launched. A collaborative effort between DEQ, CRM, DFW, MINA, NOAA, and SeaWeb. The campaign strives to capture why people value Laolao Bay, and in turn, inspire community users to help keep Laolao Bay litter free for everyone. 2013 Laolao Bay Watershed Pride Campaign (Rare) to promote the Micronesia Challenge through behavioral change by encouraging landowners to adopt good landscaping and erosion control practices in their surroundings
