Spring Predator Case Study

547 Words3 Pages

Predators have become a colossal problem lowering duck populations and overall nest success and recruitment. With the decline of apex predators such as wolves and coyotes predators such as Red Fox, raccoons and skunks have been able to run rampant and destroy duck populations altogether. The use of predator corridors or the congregation of predators in areas with large duck numbers began to become more prevalent. Nests need to have at least 15% nest success to maintain a minimum number of ducks within the population. That number is hard to maintain when Red Fox are annually killing 900,000 adult ducks within that of the breeding grounds. With that being said only one nest in ten actually produce a single healthy duckling. Predators can not …show more content…

By the end of the millennial the population had doubled in size. Conservation groups such as Delta Waterfowl and the 1985 Conservation Reserve Program have made efforts in predatory control and by introducing more wetlands within a given area. In some cases waterfowl nest success was as low as 11%, far below the minimum number to maintain the current population. Conservation efforts have seen triumphal outcomes nearly doubling nest success seeing numbers as high as 22.9%. With constant implications of spring predator management and with new habitat being established, waterfowl numbers can continue to see an increase. These numbers though great compared to years of the past, the population could be experiencing larger gains. 75% of the Prairie Pothole Region resides across the border in Canada and they have been bringing habitat loss to a new extreme. There are no current conservation efforts within Canada preserving that of wetlands or helping duck population numbers. Agriculture has run rampant and it has affected the population quite dramatically. Though the United States has shown a valiant effort in preserving and regenerating overall duck populations producing gains, more could be done to increase the number of theses wondrous creatures of the

    Their results indicated that there is a trade off with sandpipers between food availability and safety. There were far fewer than expected sandpipers in areas with high food abundance where the danger is high and greater than predicted numbers in areas where the safety increased. This led to the conclusion that the quality of a site for conservation should be determined by not only food abundance but also predation risks as well. Certain sites cannot be protected based on the fact that they have a high availability of food as those areas may also have an increased presence of predators. Pomeroys ' experiment suggests that both an abundant food source and the potential presence of predators can determine the choice of a site as a migratory stopover for sandpipers, and as such should be taken into consideration when determining habitat conservation acts for the

    Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.
