Evaluation Of Aerial Strip-Transect Surveys For Estimating Average Use By Waterfowl Wintering At Sequoyah National Wildlife Refuge, Oklahoma, 2012-2014.

Paige Schmidt, PhD & Dustin Taylor
In 2012, we evaluated aerial transects (strip transects) for surveying wintering waterfowl at Sequoyah NWR and the landscape immediately surrounding the refuge. In surveying the landscape around the refuge, we attempted to capture the area used by waterfowl making daily commute flights to forage off refuge (Johnson et al. 2014). In total, we surveyed 26,895 hectares, with the 8,464.8 hectare refuge comprising 31% of the survey area. The survey consisted of 33 transects that ranged...

San Bernardino National Wildlife Refuge: Vegetation and Landcover Mapping Using Object-Based Image Analysis and Open Source Software

Bethany DeRango
In May, 2014, staff at the San Bernardino National Wildlife Refuge (SBNWR) requested the production of a vegetation map to document the ongoing restoration of the refuge. Utilizing object-based image analysis (OBIA) a 9 class vegetation map was produced. This was a piloted effort to develop a simple, repeatable and low-cost land cover mapping framework that could be carried out on other refuges. Thus, iterative steps were taken and refined as part of the mapping...

Site-specific Protocol for Monitoring of Waterbirds Sequoyah National Wildlife Refuge

P.M. Schmidt, C.L. Lalonde, K.M. Linner, B.A. Grisham & W.C. Conway
The site-specific protocol for monitoring of waterbirds for Sequoyah National Wildlife Refuge (NWR) is based on the national protocol framework for the Integrated Waterbird Management and Monitoring Approach for Nonbreeding Waterbirds (Loges et al. 2015) [https://ecos.fws.gov/ServCat/Reference/Profile/83678]. For this survey, we define “waterbirds” as including waterfowl, cranes, long-legged wading birds, and shorebirds. The purpose of this refuge-specific protocol is to estimate temporal patterns of abundance of migrating and wintering waterbirds at the refuge in accordance with...

Site-specific Protocol for Monitoring White-tailed Deer Using Infrared Triggered Cameras Sequoyah National Wildlife Refuge

Paige Schmidt, Christina Lalonde, Jeremy Edwardson & Sarah Lehnen
White-tailed deer (Odocoileus virginianus; hereafter, deer) are a common species found throughout North America. Because deer management occurs at a localized scale, reliable estimates of population sex and age ratios are necessary to set hunt quotas and track deer population trends over time. The most widely-used deer survey techniques have been criticized in recent years for being biased. One alternative is the use of infrared camera traps. This protocol was developed to assist Sequoyah National...

A BIOENERGETIC MODEL USED TO EVALUATE MANAGEMENT STRATEGIES FOR WINTERING WATERFOWL AT SEQUOYAH NATIONAL WILDLIFE REFUGE, VIAN, OKLAHOMA

Dustin Taylor, Paige Schmidt & William P. Johnson
A primary focus of Sequoyah National Wildlife Refuge (SNWR) is to provide habitat and foraging opportunities for waterfowl and other wetland dependent species. SNWR currently meets this objective by providing wetland and agricultural habitat. Wetland restoration and enhancement projects have occurred in recent years, with the intent to sustain healthier and more diverse waterfowl and wildlife populations. However, the relationship between habitat and food availability relative to waterfowl presence has yet to be quantified. This...

Whooping Crane Winter Abundance Survey Protocol: Aransas National Wildlife Refuge

Matthew J. Butler, Bradley N. Strobel & Cinthia Eichhorn
This protocol is primarily designed to provide a mechanism for monitoring trends in whooping crane abundance on their wintering grounds along the Texas gulf coast. Secondarily, the protocol provides mechanisms for monitoring recruitment rates, the number of whooping crane pairs that recruited young into the winter flock, and whooping crane winter range expansion. Finally, this protocol is designed to augment planning and conservation efforts with information about the relationships among local whooping crane abundance and...

Sequoyah National Wildlife Refuge waterfowl land cover and habitat classification using SPOT-5 imagery

Steven Sesnie, Dustin Taylor & Paige Schmidt
Monitoring waterfowl numbers during primary migration and winter periods is essential to developing effective habitat conservation and management strategies. The relationship between available habitat and waterfowl numbers obtained from aerial survey transects is not well studied. To determine these relationships, multispectral SPOT-5 satellite imagery acquired for Sequoyah National Wildlife Refuge close to the time of waterfowl surveys was used to map habitat conditions. Robust Random Forest classification trees were used to model 16 land cover...

Appendices for Planetary Geologic Mapping: Program Status and Future Needs

James A Skinner, Alexandra E Huff, Corey Fortezzo, Tenielle A Gaither, Trent M Hare, Marc A Hunter & Holly C Buban
Appendices include the original survey, response data, and collated results related to the Open File Report. Geoscience maps, regardless of target body, are spatial and temporal representations of materials and processes recorded on planetary surfaces (Varnes, 1973; Spencer, 2000). The information and context provided by these maps promote basic and applied research within and across various geoscience disciplines. They also provide an important basis for programmatic and policy decisions (for example, H.R. 2763, 102nd Congress,...
