Brachylagus idahoensis <\/em>Leporidae – the pygmy rabbit – is\u00a0a tiny native of the American steppe. Although it is not threatened as a species, the isolated Washington population has essentially been eradicated through extreme habitat fragmentation and genetic drift. Known WA\u00a0populations\u00a0exist thanks to the efforts of the WA Department of Fish and Wildlife, which\u00a0have a captive breeding program involving non-WA rabbits, but while maintaining as much native WA genetics as possible.<\/p>\n

However, it is possible for some wild populations to have persisted, or spread to other areas from the captive breeding program enclosures. Winter is the best time to look for previously unknown populations. Tracks are, obviously,\u00a0easy to see in snow, and Pygmy rabbit tracks are\u00a0most easily\u00a0discerned from other rabbit species during the winter months.<\/p>\n

Erik (my CLM mentor) and I drove to the site of a 2015 wildfire to look for signs of the little creatures, while conducting fence inventory. We\u00a0saw plenty of fences but, sadly, no evidence of pygmy rabbits. It is likely that no population has managed to reestablish itself in the area since the last\u00a0local sightings\u00a0over 20 years ago.<\/p>\n

A very alert\u00a0whitetailed\u00a0jackrabbit. Somewhat confusingly (sorry) it is not shown begging, as I couldn’t get a good picture of that. I guess it’s also confusing that\u00a0this is not the rabbit species\u00a0that is the subject of this post.<\/p><\/div>\n

We did see a whitetailed jackrabbit though – veritable giants in comparison, this one probably stood about 30cm tall in “begging” position. I don’t believe it was actually begging the way a trained dog might, but rather that some accident of its rabbit psychology causes it to assume this pose when nervous.<\/p>\n

Zoomed in. More charismatic photos of courting males in the future, hopefully.<\/p><\/div>\n

I also got to see greater sagegrouse (Centrocercus urophasianus <\/em>Phasianidae)\u00a0for the first time. This is a pretty important species for land managers in the West, and another American steppe obligate with an isolated population in WA. They are best known for their lekking behavior during the spring breeding season, where males\u00a0gather and display their tail feathers and\u00a0enormous neck-pouches (gular sacs).<\/p>\n

Grouse in general are sometimes known to fly into barbed wire fences, which can result in mortality. Fortunately, efforts have begun to mark fences with white reflective markers in sagegrouse areas.<\/p>\n

The group we saw were congregating at the edge of a former wheat field taken out of cultivation through the Conservation Reserve\u00a0Program, so they were easy to see; in sagebrush they can be quite elusive.<\/p>\n

And here are a couple of coyotes, sprinting full speed to keep their hunting skills sharp. These deep snow conditions are optimal for running down larger animals such as deer, whose hooves\u00a0sink deeper into the powder than the padded paws of canines.<\/p>\n

Since fire can damage fences and other structures, it is important to\u00a0conduct an\u00a0inventory like this every time a wildfire occurs. Locating fences and gates, the most common structures on BLM, helps manage rangeland and keep the cows where they’re supposed to be. Fire crews can also use this spatial data for planning access routes in the event of future fires. Detailed information on the structure material, condition, and so on,\u00a0must be\u00a0collected and entered in a BLM regional geodatabase.<\/p>\n
