War in the Pacific National Historical Park burgeons with life. Scars and stains of World War II still remain on many Pacific islands, but over time, vibrant plant and animal communities have dramatically rebounded. Within the park's boundaries lie coral reefs, seagrass beds, tropical savanna grasslands, limestone forests, bogs, streams, coastal and forest wetlands, offshore islets, and even a mahogany forest! These outstanding environments create homes for rare animals and provide a laboratory for scientific inquiry and research. Take a look through these pages to become acquainted with Guam's outdoor wonders - and learn more about the NPS Inventory and Monitoring Program that keeps tabs on many of the plants, animals, and weather throughout Pacific island national parks.

The War on the Reefs

Over time coral reefs have been used - and sadly, abused. Natural disasters such as high-powered storms and wildfires have wreaked havoc on marine communities. Amphibious landings in World War II saw heavy equipment driven over reef after reef, island after island. Today, continued anthropogenic (human) impact continues to take its toll. Discover the problems coral reefs face and how you can help care for them.
