Regions L2 Landing Page Tabs

One of the major strengths of the Northeast Area is the enthusiasm and commitment of our scientists to produce the type of high quality science that the USGS is known for. Working together with our partners across the nation, we have the ability to provide complete, integrated and holistic environmental information that will produce the best results that we can achieve.

Citizen Scientists monitoring Avian populations in the Gulf Coast National Parks

Monitoring Birds in National Parks of the Gulf Coast Network

The Challenge: Avian monitoring within the Gulf Coast Network of the National Park Service is challenged to provide valid quantitative data on bird populations within park boundaries with limited financial input. Thus, citizen science (volunteer) bird monitoring has been proposed to achieve reliable estimates of bird populations and to assess the effects of habitat change and temporal dynamics...

Assessing Recreational Impact to Cliff Habitats and Rare Plants

Protected natural areas, including parks, forests, wilderness, and wildlife refuges, have a dual mandate to protect natural resources and accommodate recreational visitation. Recreational activities that occur on trails (hiking, mountain biking, horseback riding) and on recreation sites (picnicking, camping) can benefit from the development of a sustainable infrastructure of facilities that...

The Release of Parent-reared Whooping Crane Colts into the Eastern Migratory Population

The Challenge: Whooping cranes have been successfully introduced using costume rearing techniques in either a direct autumn release or in an ultralight led migration from Wisconsin to Florida. In Florida, we have also released parent-reared whooping cranes. Not much is known about the learning that takes place in this K-selected species over the almost one year that the young whooping crane...

Implementing Cross Validation Approaches for Model Selection and Evaluating Goodness of Fit in Complex Hierarchical Models

It is (relatively) easy to construct complex hierarchical models for analysis of the North American Breeding Bird Survey (BBS), but deciding which model best describes population change is difficult.  We are developing methods for model selection for BBS and other important survey data sets, and using them to refine our estimates of population change from this important survey.

Design and Analysis of Surveys for Estimation of Temporal and Spatial Change in Animal Populations

Designing and analyzing large-scale animal surveys is an important focus of our research.  Although we conduct research into analysis methods for many surveys, the primary focus of this project is to conduct analyses and develop web-based summaries of data from the North American Breeding Bird Survey (BBS).

Hierarchical Models of Animal Abundance and Occurrence

The Challenge: Research goals of this project are to develop models, statistical methods, sampling strategies and tools for inference about animal population status from survey data. Survey data are always subject to a number of observation processes that induce bias and error. In particular, inferences are based on spatial sampling – we can only ever sample a subset of locations where species...

Spatial Capture-Recapture Models to Estimate Abundance and Density of Animal Populations

The Challenge: For decades, capture-recapture methods have been the cornerstone of ecological statistics as applied to population biology.  While capture-recapture has become the standard sampling and analytical framework for the study of population processes (Williams, Nichols & Conroy 2002) it has advanced independent of and remained unconnected to the spatial structure of the population...

Environmental considerations related to mining of nonfuel minerals

Throughout most of human history, environmental stewardship during mining has not been a priority partly because of the lack of applicable laws and regulations and partly because of ignorance about the effects that mining can have on the environment. In the United States, the National Environmental Policy Act of 1969, in conjunction with related...
