Sam Droege
Sam is a Wildlife Biologist at the Eastern Ecological Science Center in Laurel, MD.
Sam has coordinated the North American Breeding Bird Survey Program, developed the North American Amphibian Monitoring Program, the BioBlitz, Cricket Crawl, and FrogwatchUSA programs and worked on the design and evaluation of monitoring programs. Currently he is developing an inventory and monitoring program for native bees, online identification guides for North American bees at discoverlife.org, and reviving the North American Bird Phenology Program.

Evaluation of canoe surveys for anurans along the Rio Grande in Big Bend National Park, Texas Evaluation of canoe surveys for anurans along the Rio Grande in Big Bend National Park, Texas
Surveys for amphibians along large rivers pose monitoring and sampling problems. We used canoes at night to spotlight and listen for anurans along four stretches of the Rio Grande in Big Bend National Park, Texas, in 1998 and 1999. We explored temporal and spatial variation in amphibian counts and species richness and assessed relationships between amphibian counts and environmental...

full text: Frogs and toads are perhaps the most approachable and available of all our wildlife. In many, if not most places, they are abundant. In wetter parts of the East, almost anyone outside on a warm rainy night in spring will hear their dream-like calls, bellows, trills and snores. Even in the deserts of the Southwest, a nocturnal trip after a summer monsoon will yield toads moving

A case for using Plethodontid salamanders for monitoring biodiversity and ecosystem integrity of North American forests A case for using Plethodontid salamanders for monitoring biodiversity and ecosystem integrity of North American forests
Terrestrial salamanders of the family Plethodontidae have unique attributes that make them excellent indicators of biodiversity and ecosystem integrity in forested habitats. Their longevity, small territory size, site fidelity, sensitivity to natural and anthropogenic perturbations, tendency to occur in high densities, and low sampling costs mean that counts of plethodontid salamanders...

Evaluation of terrestrial and streamside salamander monitoring techniques at Shenandoah National Park Evaluation of terrestrial and streamside salamander monitoring techniques at Shenandoah National Park
In response to concerns about amphibian declines, a study evaluating and validating amphibian monitoring techniques was initiated in Shenandoah and Big Bend National Parks in the spring of 1998. We evaluate precision, bias, and efficiency of several sampling methods for terrestrial and streamside salamanders in Shenandoah National Park and assess salamander abundance in relation to...

DC birdscape: a program for monitoring neotropical migrant birds in Washington, DC DC birdscape: a program for monitoring neotropical migrant birds in Washington, DC
Urban and suburban habitats often contain a variety of Neotropical migratory birds, but are poorly sampled by programs such as the North American Breeding Bird Survey. DC Birdscape was developed to inventory and monitor birds in Washington, D.C. Birds were surveyed using a systematic sample of point counts during 1993-1995. Results indicate that species richness of Neotropical migratory...
