Biology, Impacts and Control of Invasive Reptiles in the Everglades

Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.

Drought Conditions in Puerto Rico

A drought is a period of drier-than-normal conditions that results in water-related problems. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If...

National Park Service Visitor Spending Effects

The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate NPS...

North American Waterfowl Management Plan

The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats.

Understanding Coastal Change

Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

Date published: April 13, 2016

Geologic Hazards and Catastrophic Events

We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.

Connectivity of Tropical Marine Ecosystems: Understanding Biodiversity and Trophic Relationships in the Virgin Islands and Puerto Rico

Marine reserves and protected areas in the U.S. Virgin Islands and Puerto Rico encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds, but questions remain regarding how effective these areas are at preserving and protecting the habitats and species they encompass. USGS and collaborators address this question by examining the biodiversity and food web...

Earthquakes and tsunamis in Puerto Rico and the U.S. Virgin Islands

Many earthquakes and tsunamis have occurred in the northeastern Caribbean, where the movements of the Earth's surface plates are rapid and complicated. Future such events pose serious hazards to the 3.7 million people who live in Puerto Rico and the U.S. Virgin Islands.

Map Showing Susceptibility to Earthquake-Induced Landsliding, San Juan Metropolitan Area, Puerto Rico

Analysis of slope angle and rock type using a geographic information system indicates that about 68 percent of the San Juan metropolitan area has low to no susceptibility to earthquake-induced landslides. This is at least partly due to the fact that 45 percent of the San Juan metropolitan area is constructed on slopes of 3 degrees or less, which...
