This is very similar to the Kansas firearms bill last year.
http://audubonofkansas.org/2014/kansas-s...airie-chickens/1) Any federal law, treaty, regulation or executive action that specifically regulates the following is null, void and unenforceable within the state:
(1) The lesser prairie-chicken;
(2) The greater prairie-chicken;
(3) The habitats of such species;
(4) Farming practices that affect such species; or
(5) Other human activity that affects such species or the habitats of such species.
2) No official, agent or employee of the state of Kansas, or any political subdivision thereof, shall enforce or attempt to enforce any federal law, treaty, regulation or executive action that specifically regulates the (same as above).
3) And further, “It is unlawful for any official, agent or employee of the government of the United States, or employee of a corporation providing services to the government of the United States to enforce or attempt to enforce any federal law, treaty, regulation or executive action that specifically regulates the (same as above).
“Violation of this section is a severity level 10, nonperson felony.”
With this in mind, wildlife biologists or law enforcement agents with the US Fish and Wildlife Service, the Kansas Department of Wildlife, Parks and Tourism, and others, could be hauled into court and charged with a felony for any actions, as described, to protect Prairie-chickens or their habitat in Kansas.
Needless to say, any action against federal employees or their agents would be determined to be invalid in federal court (and probably in state court as well). However, a state law that makes it a felony for a state employee or others to be involved with protection of Prairie-chickens and their habitat as part of any federal threatened species recovery program may be more problematic.
