On December 7, 1941, Dwight Eisenhower was a fifty-one-year-old Bvt. Brigadier General at Fort Sam Houston in Texas. The events of that day would forever change both Eisenhower’s life and the course of world history.
Assan Beach, the 2,500-yard shoreline stretching between Punta Adilok (Adelup Point) and Punta Assan (Asan Point), which the Marines in World War II called a "pair of devil horns," is a poignant symbol of the Guam's complex history, blending indigenous CHamoru traditions, wartime struggle, and ongoing military presence. In many ways, the story of Guam can be read through the story of Assan Beach. Talk a walk through history at Assan Beach.
Cecilia Cruz Bamba was a Chamorro woman who was orphaned at the age of nine during the Japanese attacks on Guam in 1941. Motivated by the grandmother who raised her, Bamba became a senator, businesswoman, and community leader.
As climate changes, significant changes in weather conditions impact the natural environment by shifting patterns of precipitation, promoting extremes in storm behavior, and influencing bird migration, invasive species spread, coral reef decline, and much more. The Pacific Island Network (PACN) undertakes systematic long-term monitoring of a wide variety of natural resources to accurately determine if change is occurring and why.
The primary duty of the Community Volunteers Ambassadors is to encourage local residents, particularly young people, to volunteer for climate-resilience-related projects in the park.
In response to stresses such as higher water temperatures, corals can lose the symbiotic microscopic algae (which provides up to 95% of the coral’s nutrition) from their tissues causing them to look white or "bleached." If favorable conditions return, corals can sometimes recover. However, bleached corals are more vulnerable to disease and other stressors, which can lead to death. This worldwide trend of coral bleaching is linked to global warming.
War in the Pacific National Historical Park is working to protect Guam’s biodiversity by managing invasive species like brown tree snakes and little fire ants while safeguarding native wildlife, including the endangered Guam tree snail. A recent study assessed the park’s Guam tree snail population, providing essential data to inform conservation efforts aimed at restoring the island’s fragile ecosystem.
While Guam is only 212 square miles, the island is rich in history. Only hours after Pearl Harbor was attacked, the Japanese began aerial bombings on Guam. After two days of strafing, the Japanese came ashore and hours later the naval governor surrendered the American territory. The island remained under Japanese control for 31 months until July 21, 1944 when the United States returned and liberated the island.
