The Yellowstone park officials have now been told to produce a full-fledged new report on the condition of the park after its removal from the List of World Heritage Danger sites.

The park's original draft progress report will be submitted to the United Nations Educational, Scientific, and Cultural Organization World Heritage Danger sites. One of the essential issues that this report will be dealing with is the bison population of Yellowstone National Park.

About the bison population, the park officials have stated that the population is too high and so they are currently evaluating how feasible it will be to institute a bison quarantine program. Under this program, they will be testing all the animals for disease. All the animals that test negative will be eventually relocated. This relocation can be to even tribal lands for the purpose of conservation, commercial, and cultural uses as well.

Rick Hoeninghausen, director of sales and marketing for Xanterra Parks & Resorts' Yellowstone National Park Lodges, said, "Throughout the winter season, the park becomes a visual smorgasbord that is both strange and wonderful".

There are a lot more strange experiences that the visitors can expect during a winter visit to the park. This includes ice fog, which happens when the conditions are just right and visitors get to see light-reflecting ice crystals floating in the air.

The visitors will also be able to witness the monkey flowers which are only a few inches tall, these strange yellow wildflowers grow exclusively around hot springs. These are able to survive the winter because of their short stature and the heat of the springs.

Another thing is the snowball beards. This can be seen on the Bison when they forage for food beneath the snow and can sometimes be seen with large clumps of snow and ice dangling from their chin hair.
