For My Readers In The Boise Area: "Ridge to Rivers seasonal trail closures start December 1"

 An article from KIVI Channel 6 on the closures:

Beginning December 1, the following trails will be closed to the public:

• Landslide Loop Trail #70 [ridgetorivers.org]: The two-mile trail located above Hidden Springs is closed annually from December 1 to March 31 for wintering wildlife. 
• 8th Street Extension Road [ridgetorivers.org]: The road is closed to vehicles from the 8th Street Motorcycle Trailhead to the Boise Ridge from December 1 to May 15 every year. The gate will be closed, preventing full-size vehicles from accessing the unpaved road to protect the road and trailhead integrity. 
• Hawkins Range Reserve [cityofboise.org]: The reserve, which is located off N. Bogus Basin Road, features a 5.7-mile directional trail called Hawkins Loop [ridgetorivers.org] and a .6-mile nested trail called Harrow Trail [ridgetorivers.org]. The reserve and all trail access is closed seasonally from December 1 to April 30 to protect critical habitat and important wildlife corridors. 

Trails closing later this winter, weather dependant, date TBD:

• Old Pen Trail #15A [ridgetorivers.org]: In partnership with the Idaho Department of Lands, the City of Boise has permitting authority to close the .6-mile trail this winter to prevent damage to the trail. Trailhead parking will not be affected by this seasonal trail closure. This is the third winter the city will close the trail, in an effort to prevent further damage while slowly improving tread conditions over time.  
• Ridge Crest Trail #20 [ridgetorivers.org]: Due to high clay content, this area in Military Reserve is especially prone to muddy conditions. The 200 yards from the trailhead parking area on Mountain Cove Road to the Archery Range parking lot will be closed. Users will be routed through the Archery Range parking lot to access other trails in this area.

These two trails are expected to remain closed through early March.
