Cervid Disease Update

Add New Jersey and South Dakota to the list of states reporting an epizootic hemorrhagic disease (EHD) outbreak in white-tailed deer this year. Find more info here:

New Jersey
South Dakota

Bluetongue has been reported in Missouri by CBS News. Bluetongue is another virus closely related to EHD, and is also spread by midges, a biting insect. However, some say that only cattle get bluetongue. Others say deer do too, but very rarely.

In Nebraska, the state veterinarian is saying that cattle in the state are getting EHD, which again is considered to be a rare occurrence. He is seeking more information from cattle owners whose animals are experiencing EHD symptoms (which are virtually identical to bluetongue symptoms, which is common in cattle). Read the press release here.

In Washington, hunters have been finding limping elk with deformed hooves since the 1990s. Now the disease is spreading, and Oregon Public Broadcasting has the story.

Finally, in Texas, officials had set up a containment zone when chronic wasting disease (CWD) was detected in deer on the border with New Mexico. However, the latest news from the San Angelo Standard-Times says that the new rules will be delayed until the Texas Parks and Wildlife Commission on November 7-8. According to the Austin Statesman, that’s after the archery season and a few days after the start of the standard deer season.

An Outdoor Life blog also had a few words to say about the restrictions, putting them in national context. Read that here.

 

Prairie dogs, cattle, and grass

Western folklore says that prairie dogs and cattle compete for grass. However, a cattle-exclusion study found that the prairie dog population increased in plots where there were cattle compared to the prairie dog population in plots where cattle were excluded. The authors say the two species have a synergistic impact on the grassland habitat. Read more in the journal Ecology.
A 2007 paper in Frontiers in Ecology and the Environment said that prairie dog populations over a certain level would reduce weight gain in cattle grazing in the area. You can read a Denver Post newspaper article onthe study here.
