Excerpts from Wikipedia Geography Guam lies between 13.2°N and 13.7°N and between 144.6°E and 145.0°E, and has an area of 209 square miles (541 km2), making it the 32nd largest island of the United States. It is the southernmost island in the Mariana island chain and is the largest island in Micronesia. This island chain was created by the colliding Pacific and Philippine tectonic plates. The Mariana Trench, a deep subduction zone, lies beside the island chain to the east. Challenger Deep, the deepest surveyed point in the Oceans, is southwest of Guam at 35,797 feet (10,911 m) deep. The highest point in Guam is Mount Lamlam, which is 1,332 feet (406 m). The island of Guam is 30 miles (48 km) long and 4 mi (6 km) to 12 mi (19 km) wide. The island experiences occasional earthquakes due to its location on the western edge of the Pacific Plate and near the Philippine Plate. In recent years, earthquakes with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike the Anatahan volcano in the Northern Mariana Islands, Guam is not volcanically active.[6] However, due to its proximity to Anatahan, vog does occasionally affect Guam.[7] The northern part of the island is a forested coralline limestone plateau while the south contains volcanic peaks covered in forest and grassland. A coral reef surrounds most of the island, except in areas where bays exist that provide access to small rivers and streams that run down from the hills into the Pacific Ocean and Philippine Sea.[8] The island's population is most dense in the northern and central regions.[5] Climate The climate is characterized as tropical marine. The weather is generally hot and very humid with little seasonal temperature variation. The mean high temperature is 86 °F (30 °C) and mean low is 76 °F (24 °C) with an average annual rainfall of 96 inches (2,180 mm). The dry season runs from December through June. The remaining months constitute the rainy season. The months of January and February are considered the coolest months of the year with night time temperatures in the mid to low 70's and generally lower humidity levels. The highest risk of typhoons is during October and November. They can occur, however, year-round. An average of three tropical storms and one typhoon pass within 180 nautical miles (210 mi; 330 km) of Guam each year. The most intense typhoon to pass over Guam recently was Super Typhoon Pongsona, with sustained winds of 125 miles per hour, which slammed Guam on December 8, 2002, leaving massive destruction. Since Super Typhoon Pamela in 1976 wooden structures have been largely replaced by concrete structures.[9][10] During the 1980s wooden utility poles began to be replaced by typhoon-resistant concrete and steel poles. After the local Government enforced stricter construction codes, many home and business owners built their structures out of reinforced concrete with installed typhoon shutters. Ecological issues Guam exemplifies the effects of bioinvasion. The brown tree snake Coconut Rhinoceros Beetle Adults are the injurious stage of the insect. They are generally night-time fliers and when they alight on a host, they chew down into the folded, emerging fronds of coconut palms to feed on sap. V-shaped cuts in the fronds and holes through the midrib are visible when the leaves grow out and unfold. If the growing tip is injured, the palm may be killed or severe loss of leaf tissue may cause decreased nut set. Feeding wounds may also serve as an infection pathway for pathogens or other pests. The effects of adult boring may be more severe on younger palms where spears are narrower. Mortality of young palms has already been observed on Guam. Oviposition and larval development typically occurs in decaying coconut logs or stumps. Control measures have been developed for CRB and the current strategy on Guam is to implement an integrated eradication program using pheromone-baited, attractive traps to capture adults, various methods to eliminate infested and susceptible host material, and pesticides to kill larvae and adults. Pesticides may also be applied to uninfested trees as a preventive treatment. USDA-APHIS has completed an Environmental Assessment for the coconut rhinoceros beetle eradication program on Guam (EA Number: GU-08-1, http://www.guaminsects.net/uogces/kbwiki/images/d/dc/CRB_EA.pdf). The eradication program is a cooperative effort between USDA (APHIS and Forest Service), GDA and the University of Guam (UOG). This document follows the Forest Service Pest Risk Assessment (Kliejunas et al. 2001)format and is intended to provide information regarding the current status of CRB on Guam, its potential to spread to uninfested locales, and the consequences of establishment. The high, moderate or low risk values are based on available biological information and the subjective judgment of the authors. Other invasive species From the seventeenth through nineteenth centuries, the Spanish introduced pigs, dogs, chickens, the Philippine deer (Cervus mariannus), black francolins, and water buffalo. Water buffalo, known as carabao locally, have cultural significance. Herds of these animals obstruct military base operations and harm native ecosystems. After birth control and adoption efforts were ineffective, the U.S. military began euthanizing the herds in 2002 leading to organized protests from island residents.[17] Other introduced species include cane toads imported in 1937, the giant African snail (an agricultural pest introduced during WWII by Japanese occupation troops) and more recently frog species which could threaten crops in addition to providing additional food for the brown tree snake population. Reports of loud chirping frogs native to the Caribbean and known as coquí, that may have arrived from Hawaii, have led to fears that the noise could threaten Guam's tourism.[18] Introduced feral pigs and deer, over-hunting, and habitat loss from human development are also major factors in the decline and loss of Guam's native plants and animals.
