Hardin Waddle, Ph.D.
Hardin Waddle currently works as a research ecologist for the USGS, where he serves as the principal investigator for the south-central region of the Amphibian Research and Monitoring Initiative (ARMI). His research interests include population ecology and conservation of amphibians and reptiles, primarily in the wetlands and swamps of the southeastern United States.

A review of pipe and bamboo artificial refugia as sampling tools in anuran studies A review of pipe and bamboo artificial refugia as sampling tools in anuran studies
Artificial pipe-like refugia have been used for more than 40 years in anuran studies, and have captured 28 species, primarily (82%) hylid treefrogs. Early pipe-like refugia were made using cut pieces of bamboo in the tropical forests of Puerto Rico, but most recent studies have used synthetic pipes and have occurred primarily in the southeastern United States. Characteristics of...

Anuran site occupancy and species richness as tools for evaluating restoration of a hydrologically-modified landscape Anuran site occupancy and species richness as tools for evaluating restoration of a hydrologically-modified landscape
A fundamental goal of wetland restoration is to reinstate pre-disturbance hydrological conditions to degraded landscapes, facilitating recolonization by native species and the production of resilient, functional ecosystems. To evaluate restoration success, baseline conditions need to be determined and a reference target needs to be established that will serve as an ecological blueprint...

Wetland Reserve Program enhances site occupancy and species richness in assemblages of anuran amphibians in the Mississippi Alluvial Valley, USA Wetland Reserve Program enhances site occupancy and species richness in assemblages of anuran amphibians in the Mississippi Alluvial Valley, USA
We measured amphibian habitat use to quantify the effectiveness of conservation practices implemented under the Wetland Reserve Program (WRP), an initiative of the U.S. Department of Agriculture’s Natural Resources Conservation Service. From February to June 2007, we quantified calling male anurans in cultivated cropland, former cultivated cropland restored through the WRP, and mature...

Co-occurrence of invasive Cuban Treefrogs and native treefrogs in PVC pipe refugia Co-occurrence of invasive Cuban Treefrogs and native treefrogs in PVC pipe refugia
The Cuban Treefrog (Osteopilus septentrionalis) was first introduced to Florida at Key West. Since this introduction, Cuban Treefrogs have spread to Miami and are now established throughout most of peninsular Florida. Cuban Treefrogs can become very abundant in areas they colonize. Several reasons contribute to their success, including a generalist diet, high fecundity and the ability to...

Trends in amphibian occupancy in the United States Trends in amphibian occupancy in the United States
Though a third of amphibian species worldwide are thought to be imperiled, existing assessments simply categorize extinction risk, providing little information on the rate of population losses. We conducted the first analysis of the rate of change in the probability that amphibians occupy ponds and other comparable habitat features across the United States. We found that overall...

A quantitative assessment of the conservation benefits of the Wetlands Reserve Program to amphibians A quantitative assessment of the conservation benefits of the Wetlands Reserve Program to amphibians
The Mississippi Alluvial Valley (MAV) originally consisted of nearly contiguous bottomland hardwood (BLH) forest encompassing approximately 10 million hectares. Currently, only 20–25% of the historical BLH forests remain in small patches fragmented by agricultural lands. The Wetlands Reserve Program (WRP) was established to restore and protect the functions and values of wetlands in...
