Lots o’ Legislation

Gray_wolfI know, you are trying to focus on science and have no interest in the political scene. And I know that lots of bills get passed, but few of them become laws. Every once in a while, it is worth mentioning the gears of law, though. In this case it is worth mentioning because both the Idaho and Utah legislatures were very busy in late February creating new laws about endangered species.

The Associated Press reported that a bill that passed the Idaho Senate “would make it against state policy for federal officials to introduce or reintroduce any threatened or endangered species in Idaho without state approval.”

But there’s not much more than that on the bill. Read it the brief piece on The Oregonian website, here.

Utah was extra busy. They’ve got three bills in the works. One House bill would, according to the Salt Lake City Tribune, “allow county assessors to reduce a property’s tax burden if its value is impacted by designation as critical habitat for threatened or endangered species.”

Another House bill, “asks the federal government to not designate any private land in San Juan County as sage grouse habitat,” says the Salt Lake City Tribune. And a Senate bill which, “endorses Iron County taking over recovery of the Utah prairie dog” from the US Fish and Wildlife Service.

The Utah legislature also put $300,000 in its budget to prevent the federal government from reintroducing the gray wolf into the state, another Salt Lake City Tribune article says. The article says that federal officials deny that any such reintroduction is planned.

And props to Brian Maffly, the Salt Lake City Tribune reporter on both of those stories for making dull legislative news lively and easy to understand.

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.
