Letter: We should minimize construction of bike trails in environmentally sensitive microhabitats

(Francisco Kjolseth | The Salt Lake Tribune) The Avenues Ridgeline Trail is a new trail (combining parts of old trails + some totally new) with sweeping views of the Salt Lake Valley from the “summit.” The highlights of the trail right now are beautiful yellow leafy arnica, which are everywhere, along with Missouri milkvetch. Though numerous variations exist It's about 3 miles long and not too difficult except for a couple short, steep climbs. The trail is primarily used for hiking, mountain biking, running and nature trips May 12, 2021.

I walk in the foothills above Salt Lake City every week. With a biologist’s eye, I observe wildlife and watch the seasons unfold. Bicyclists are unfailingly polite and we have shared the trails for years.

The City has begun construction on a major reconfiguration of trails in the foothills (The Tribune, May 12). Part of the plan is to turn some of the small canyons (e.g. Dry Creek) into banked downhill runs for

bicyclists, and to place hiking trails on the sides above.

An aspect that was overlooked in the article and perhaps in the planning is that the canyon bottoms are narrow strips of distinctive habitat with high biodiversity and aesthetic value. These are important habitat corridors where moisture is higher, trees are larger, plant and animal species concentrate.

There are already at least two de facto downhill bike runs in the vicinity of Dry Creek, which should suffice. I strongly encourage the protection of the narrow valley bottoms as environmentally sensitive microhabitats. We should minimize construction in them, retaining their use for low-impact hiking and trail-running.
