If they are just loose domestic rabbits, trap away, year round and as many as you want. I've done several of these jobs, drives me crazy how folks just turn these things loose and not worry about the impact on the habitat.
Some relevant information here:http://wdfw.wa.gov/living/rabbits.html
I see the pika is not listed on this page. It's always called a rabbit and it's the smallest of the rabbits. Is it not a rabbit? If not, what is it considered?
Hmmm IV seen many pika around me high Buck hunting area. Didn't know they were protected or anything I thought there was a good population
