Maui Nui Marine Resource Council Launches Campaign to Encourage Chemical-Free Landscaping to Protect Coral Reefs and Marine Wildlife
MAUI, HI – As part of its work to protect and promote healthy coral reefs, clean ocean water and abundant native fish in Maui County, Maui Nui Marine Resource Council has launched an educational campaign to encourage private and public landowners, golf courses and landscapers to switch to organic land management. The organization launched this campaign after gathering research on the impacts that toxic pesticides, fungicides, herbicides and synthetic fertilizers have on coral reefs and marine wildlife.
“Many people want to help protect the ocean, but they aren’t aware that they can do that through organic land management,” says Grace Silver, Project and Research Coordinator at Maui Nui Marine Resource Council. “This campaign will educate and encourage private and public landowners to give up use of landscape chemicals to protect the ocean environment and create a healthier and thriving microclimate on their own land.”
Maui Nui Marine Resource Council is working with Beyond Pesticides, National Organic Farming Association and local organic land management experts to provide the community with helpful information for landowners and land management experts to make the switch to organic land management. Because cumulative impacts can be so detrimental, every single property that makes the switch will make a difference towards creating a cleaner and healthier environment around them.
“Numerous scientific studies have shown that the use of synthetic chemicals on land have significant and adverse impacts to coral reef ecosystems and aquatic species,” reports Silver. “Some of these negative impacts include coral reef bleaching, eutrophication, biomagnification, reproduction inhibition and increased disease in fish and marine wildlife.”
“Through our research, we’ve found that a majority of chemicals applied to our land for landscaping and pest control often end up in the ocean,” explains Meredith Beeson, Project and Research Coordinator at Maui Nui Marine Resource Council. “Once these chemicals make their way into aquatic environments, they harm coral reefs by hindering their ability to feed and reproduce.”
“In order to protect our oceans, this chemical runoff needs to be reduced (or ideally stopped) from reaching the ocean,” says Beeson. “The solution is organic land management.”
According to a study published in the Journal of Agricultural and Environmental Ethics by David Pimentel, less than 0.1% of pesticides applied for pest control reach their target pests. Thus, more than 99.9% of pesticides used move into the environment where they adversely affect public health and beneficial biota, and contaminate soil, water, and atmosphere of the ecosystem.
Problems caused by landscaping chemicals and synthetic fertilizers entering the marine environment include:
• Tumor-causing diseases in turtles, as documented by the University of Hawaii, Manoa by Celia Smith and Walter Zimmermann.
• Creation of dead zones through the process of eutrophication, as documented by InTeGrate in “Managing Runoff to Reduce the Dead Zone.”
• Degradation of coral reefs, leading to economic impacts, as documented by University of Hawaii, Manoa in “Economic Value of Hawaii’s Nearshore Reefs.”
• Death of zooxanthelle (coral symbiont) which leads to coral bleaching, as documented by the Marine Pollution Bulletin by C.M. Shaw, J. Brodie, and J.F. Mueller.
• Potential human health impacts through chemical exposure, as documented by the Agency for Toxic Substances and Disease Registry.
“Whether you have a small yard or run a large-scale farm, organic land management can help protect Maui’s coral reefs and aquatic organisms” says Beeson. “Another benefit of organic landscaping is that it ultimately allows the land to sustain itself without large amounts of human intervention, saving time, energy and money in the long run.”
Maui Nui Marine Resource Council has created a webpage at https://www.mauireefs.org/what-we-do/pesticides/ with resources to help land managers, owners and landscapers obtain more information on organic land management. These resources focus on common issues found in Maui County.
Maui Nui Marine Resource Council staff members Meredith Beeson and Grace Sliver examine landscaping plants and discuss organic land care methods as part of our new Pesticide Education Program.
