    Four wolf trapper courses scheduled across the state in November and December

    Attention new wolf trappers: There are four upcoming wolf trapper education classes scheduled in Idaho Falls, Lewiston, Coeur d’Alene and Nampa. If you plan to trap wolves this season, plan to attend one of these classes.

  • Oct. 10 is new opener for wolf trapping in some units

    Idaho Fish and Game Commission in August extended hunting and trapping seasons for wolves in many units for fall/winter hunts.

  • Gavel, enforcement,

    F&G seeks comments on proposal to extend check times for winter wolf snaring in two units

    Currently trappers are required to check all snares or traps placed for gray wolves at least once every 72 hours; proposed rule would extend that time period for snares only and in limited areas

  • Grizzly bear in Yellowstone Park

    F&G Commission moves forward with grizzly bear hunt, delays decision on extending wolf hunting and trapping seasons

    At its March 22 meeting in Boise, the Fish and Game Commission instructed staff to draft a proposal for a fall grizzly bear hunt in which one male bear could he harvested.

    Fish and Game biologists are scheduled to present the commission with proposed hunting season options for Commission action at the Commission’s May 10 meeting in McCall.  

  • Wolf Trapper Certification Classes Scheduled in Coeur d'Alene

    Idaho rules require a Wolf Trapper Certification class be completed and passed before a person can purchase wolf trapping tags. The course includes instruction in the classroom and a field demonstration, followed by a written exam. Courses are offered periodically throughout the year.

    Two separate and complete wolf trapping certification classes have been scheduled in Coeur d’Alene. The dates are Friday, February 9 and Saturday, February 10. The classes will be held at the IDFG Panhandle Region office in Coeur d’Alene. Advance registration is required.

  • Wolf trapping certification course offered in Nampa December 16

    Trappers interested in learning more about the specifics of trapping wolves are reminded that Idaho rules require trappers to successfully complete a Wolf Trapper Certification course before they can purchase wolf trapping tags.

    The Idaho Department of Fish and Game will sponsor a certification course in Nampa on Saturday, December 16 from 9 am to 4:30 pm. The course will be held at IDFG’s Fisheries Research building at 1414 East Locust Lane.

    Wildlife CSI - Panhandle elk mortality study

    The Panhandle region placed 172 GPS radio-collars on 6-month old elk calves in the Coeur d’Alene and St. Joe River drainages since 2015.  A couple reasons we collared so many elk was to determine survival rates and for those elk that didn’t make it, find out why they died.

Health Issues Which May Affect This Animal

What Causes This Disease?

Hydatids are the immature form of a tapeworm called Echinococcus granulosus. Echinococcus granulosus is a very small (3-5 m) tapeworm that requires two different animal species, a canid and an ungulate, to complete its lifecycle.

Where Is The Disease Found?

Hydatid disease is found around the world including North America where it exists in two forms – a domestic form involving domestic dogs and domestic sheep and a sylvatic form involving wolves or coyotes and ungulates. The most common form of E. granulosus is found in domestic dogs and sheep, and is found worldwide, including the western USA. The form in domestic dogs and domestic sheep is the most common source of the disease in humans. There are numerous strains of E .granulosus worldwide that occur in various host species systems e. g. wolves and wild ungulates in temperate North America, dingos and kangaroos in Australia, and jackels and domestic cattle in Africa. Hydatid cysts have been found in cattle and domestic sheep, deer, elk,. moose and mountain goats in Idaho. Adult tapeworms have been found in wolves and coyotes in Idaho.

Signs of Disease

The adult tapeworm occurs in the intestines of wolves, coyotes and foxes but they are generally asymptomatic. The larval form or hydatid cyst occurs in moose, elk and deer, and can occur in humans. In moose, deer, and elk, the cysts have thick walls and are filled with a clear watery liquid. The cysts are usually found in the lungs but can also occur in the liver or other organs. Cysts can vary in size from ¾ to 4 inches in diameter and contain hundreds of juvenile tapeworms. The presence of hydatids in herbivores usually does not cause clinical signs unless the cyst obstructs normal body function. If cysts rupture, illness can be severe.

What Causes This Disease?

The lice that are found on wolves are usually Trichodectes canis.

Where Is The Disease Found?

Trichodectes canis is found in wolves across most of North America. The louse has been documented on wolves in Idaho.

Signs of Disease

Trichodectes canis on wolves is typically found in low numbers. Lice are small, about the size of a flattened rice grain, and are usually found in the groin and armpits. In large numbers, the lice tend to cause irritation and itching, which results in a diamond shaped area of hair loss over the back of the affected animals.

What Causes This Disease?

Sarcoptic mange is caused by a mite, Sarcoptes scabiei var canis. The mites burrow into the skin, mate and lay eggs. The eggs hatch and grow into adult mites in approximately 2 weeks.

Where Is The Disease Found?

Sarcoptic mange is found throughout North America, including Idaho.

Signs of Disease

Animals infected with sarcoptic mange typically scratch excessively and have moderate to severe hair loss. The itching often results in excoriations of the skin and oozing of serum which creates crusts over the skin. The affected skin appears dry, flaky, thickened, and wrinkled. Some animals may appear weak and thin and some may die from secondary infections. Infected animals tend to be more visible in fall and winter.

What Causes This Disease?

Tapeworms are segmented worms that are usually found in the small intestine or other tubular structures of animals. There are numerous species of tapeworms that affect a variety of animals with highly variable life cycles and many sizes.

Where Is The Disease Found?

Tapeworms are found worldwide and have been reported from many species of wildlife in Idaho.

Signs of Disease

Typically animals that are infected with tapeworms show no outward signs. Tapeworms are occasionally found when animals are examined after being harvested by hunters.
