“Wildlife Management is not about an individual member of the population but the population since the population is the renewable natural resource.”
Forecasting the Abundance of Whooping Cranes Overwintering Along the Texas Coast: Since 1938, the whooping crane (Grus Americana) population has been “censused” on their wintering grounds which are on and around Aransas National Wildlife Refuge. Though data are not truly a census but the maximum number of whooping cranes observed each winter, valuable insight into whooping crane population dynamics can be obtained from these data such as average annual growth rate, typical range of annual growth rates, and cyclic patterns in population trajectories. These data will be used in autoregressive integrated moving average (ARIMA) models to forecast future abundance and determine extinction probability. Further, these data will be used to evaluate the impacts of unusual, sustained declines in growth rate on population trajectories. For example, census data from the winter of 2008–2009 indicated it was “bad year” for whooping cranes along the Texas coast. Simulation of such “bad years” for varying periods of time will help managers understand the potential resilience of the whooping crane population and inform management decisions.
Understanding the Relationships between Whooping Crane Population Growth Rates and Environmental Conditions: The objective of this project is to examine the relationships between whooping crane population growth rates and freshwater inflows, salinity levels, drought, red tide, and climatic and solar cycles. If environmental or climatic influences are indicated, years of poor population growth may be predicted prior to whooping crane arrival on their wintering grounds allowing management intervention if warranted. Information from this project will help managers and the whooping crane recovery team develop adaptive management strategies and provide data for structured decision making.
Revision and Improvement of Whooping Crane Aerial Survey Techniques: The goal of this project is to develop a standardized, robust technique that estimates whooping crane abundance on the wintering grounds. Standardization of the technique will reduce “protocol creep” as time passes, ease biases introduced by changes is observers through time, and provide a defensible monitoring protocol.
Using Camera Trapping to Monitor Wildlife Populations without Marked Individuals (Rare and Elusive Species): A National I&M objective is to develop useful monitoring techniques for animal species. Though many monitoring techniques exist, few are robust enough for monitoring rare and elusive species. Many techniques only provide information about presence-absence or occupancy probabilities. Monitoring abundance or density can be more useful for management activities but many abundance techniques are reliant on marked animals. However, capture and tagging can be quite expensive. Camera-trapping has been used extensively for many rare and elusive species but it is often unclear if results reflect population trends. A new suite of models based on site occupancy and hierarchical modeling are available that can be used to estimate abundance from repeated count data. We are using elk (Cervus elaphus) at Bosque del Apache National Wildlife Refuge to test these new models. New Mexico Department of Game and Fish were capturing and immobilizing elk for CWD testing during the winter of 2010-2011 which afford us an excellent opportunity to tag and radio-collar elk for use as a model species. This allows us to implement tried and true techniques such as mark-resight and distance sampling for comparison with the new models.
Survival, Habitat Use, and Movement Patterns of Elk at Bosque del Apache NWR: Elk abundance has recently increased at Bosque del Apache National Wildlife Refuge. The Refuge’s primary management objective is to provide habitat and food for waterfowl and sandhill cranes (Grus canadensis) that overwinter at the Refuge or use it during their migration. To provide an adequate amount of nutrition for the birds, corn fields are planted on the Refuge. Elk are believed to be depredating the corn crops, thereby interrupting the Refuge’s management strategy. The objectives of this study are to investigate elk movement patterns, habitat use, survival, and depredation of corn by elk. To examine these factors, we are marking and tracking adult elk with radio- or GPS-collars. We will monitor collared elk into November 2013 to estimate cause-specific mortality rates, their habitat preferences, and their seasonal and temporal movement patterns. We will also estimate crop damage due to elk and recruitment rates of elk calves into the adult population. Refuge staff will use results of this study to adjust their management practices and establish a harvest plan to manage elk abundance. The intended outcome will be to minimize the amount of crop damage by elk on the Refuge. This project has brought together U.S. Fish and Wildlife, New Mexico Department of Game and Fish, Texas Tech University, and USGS personnel to help manage the elk herd of the Middle Rio Grande Valley in New Mexico. Agency partnerships are integral to conservation success.
