I stopped by and took a few photographs. The location is 39° 44′ 24.72″ N 105° 13′ 9.60″ W. (aka 39.7402, -105.219333)

This is the technology-enabled wildlife crossing; notice the overhead lights that increase the visibility in this area. Notice the big yellow warning signs, and the flashing lights (currently off) above and below them.

Elk’s Perspective

This is the only break in the high elk fence along this section of the road. Elk/deer soon learned to cross here.

Sensor

The sensors detects a large body entering the crossing; at which point the system engages the flashing warning lights.

Elk

My daughter felt this posting was not complete without sharing a photograph of Elk. Here is an awesome one by Ranger Shaina (Shaina Niehans.)

Update: This wildlife crossing has been recorded.

It has become increasingly clear that dog waste  is harmful to the environment in many ways (especially in the quantities left by large numbers of regular visitors.) Not only should we bag it, but we need to dispose of those bags.

It is great to see people communicating that message with a sense of humor:

Elk moving down from the hills around Golden Colorado have had suffered a roadkill problem for a while. These negative human-wildlife interactions cause significant vehicle damage (even injury/death) for the human, and even more significant injury (almost hopefully quick death) for the wildlife.

Signs didn’t work (enough)

For years there have been “massive signs” saying watch for wildlife, but still the number of Elk carcasses (and presumably damaged cars) piled up. It was a very sad situation. Then, some smart folks at C-DOT brought technology to play…

The Elk Crossing (Solution)

Along both sides of the road a high Elk fence was built, and it had the (relatively new) “exit ramps”. These exit ramps slope on the inside (road side) but drop straight down on the outside. Elk/wildlife outside would not “climb a wall” to get in, but wildlife on the inside would be able to get out. Very nice. That said, the amazing part is the “elk crossing”…

At a high/visible (and newly well lit) place a crossing was designed and designated with gaps in the fence. Motion sensors at each gap detect if a large animal (e.g. an Elk or Deer) were at the gap, and the crossing lights (flashing “slow down” signs) would engage for a few minutes. How excellent! Day or night these lights would alert drivers to an immediate and present danger. Not just some “Wildlife might be here some time” but “caution: wildlife are here/right now!”

I’ve been fascinated by this experiment since I first noticed it, and I cannot believe I’ve not blogged about it before. For starters, every time I want to discuss it, I need something to link folks to so they can “see” (or read about) the crossing, with it’s neat design. I don’t have them now, but I’ll find photos (and/or stop take some) to illustrate the design and post them here.

Since this wildlife crossing as been active I’ve noticed a dramatically reduced number of carcasses. In fact, only one (and sadly on the crossing implying the technology or driver didn’t react fast enough) … but one is a massive reduction in damage. I suspect this system pays for itself in terms of reduced pain/suffering/damage for the people/property, and not to mention how it helps the Elk/Deer.

I do hope to see more of these in years to come.

Update: I found this paper on “advances in wildlife crossing” that has some good diagrams/explanations.

 

Snowy Owl by Show Me Nature Photography

I should be feeling for the lemmings and not just the Snowy Owls because a population decline in one, becomes a tough time for the other, and so both are suffering. The up side for humans, is an irruption of big beautiful birds “down south” in North America.

One of my goals of 2012 is to make the extra efforts to live my wildlife life. Today that meant getting up at 4:45a.m. driving over an hour to the “flatlands” (the plains) and visiting Barr Lake State Park. I do not chase birds, but word on the Colorado Birds mailing list was that this might be as much as a 40-50 year irruption. Snowy Owls have been spotted for the past few weeks, and much as I’d hate to stress and already stressed species, I couldn’t resist the opportunity to see such an amazing creature. I could keep my distance, and still get an amazing experience.

I arrived at the fields where a darker (and perhaps younger) Snowy Owl had been spotted, and I arrived in the dark. I was driving slowly down a dirt road when all of a sudden the owl materialized in front of me, big white bird in the dark, and a big wide white wing span. Oh my gosh, I had but arrived and there was the bird. I pulled over, turned off my lights/car and sat. Not pleased I had come closer than I intended, but hoping to minimize any interruption. It was pitch dark but the bird was just ahead on a short post. It didn’t seem bothered by me (now) and I was blessed with a sunrise slowly illuminating this beautiful bird. We must’ve sat there for 20 minutes or more.

The bird flew north over the field, presumably still hunting, but oh so low … even a northern harrier would be hard pressed to fly like that. I  watched the bird fly low across the field, land on a post, sit, then repeat. After a while I noticed the bird land in the middle of a field, and seemingly just hang out. (Most photos I’d seen of Snowy Owls had been atop power poles, and it was fascinating to see how low this one was happy to be. I now know to check fields and low perches for the birds.)

I moved on, hoping I’d kept my distance sufficiently (after the initial unintentional encounter) and went for a hike at Barr Lake. There I saw Bald Eagle, Belted Kingfisher, Northern Harrier and a bunch of Buteo and American Kestrels.

A morning most definitely worth losing sleep for…
