Lions Fire Morning Update 7-5-18 
The Lions Fire showed no growth yesterday, and continues to be 4,000 acres and 60% contained. Crews remaining on the fire are reinforcing and securing the fireline, in order to ensure that it will hold as conditions become drier and hotter throughout the summer. Higher winds are projected for today and tomorrow, and crews are monitoring for threats to the line or spot fires. There are still unburned pockets of fuel within the unit, which will continue to be consumed in the coming weeks. A small amount of smoke production is likely to continue during this process, without creating significant impacts for nearby communities.
Air quality in Mammoth Lakes and the surrounding areas is expected to continue to be slightly affected by smoke from larger wildfires elsewhere in the state, such as the County Fire in Yolo County, CA. Residents and visitors are advised to limit their exertion outdoors should periods of heavy smoke occur.
As the need for active firefighting decreases, firefighters are reducing the impacts that fire operations have had upon the wilderness character of the area, a process known as “suppression repair.” Techniques may include repairing damaged trails, clearing cut trees and brush, or creating simple drainage structures to prevent erosion.
Located between the footprints of previous fires, the Lions Fire is contributing to diverse and healthy forest ecology. The area will ultimately be more resilient in drought conditions, and better protected against future wildfires.
The following National Forest System Trails near the Lions Fire area have been temporarily closed: Sierra National Forest Trails No. 26E01 (Mammoth Trail) to the Inyo NF Boundary, 26E14, 26E56, and 26E46 from the Inyo NF boundary. Inyo NF trail closures include 26E01 from the Sierra NF to 2601 junction. Trail closures will remain in place until fire management staff determines that it is safe to reopen the area.
Shuttles to Devils Postpile National Monument and Reds Meadow Valley are running, and trails there are open. The Pacific Crest Trail and the John Muir Trail are open. Visitors should expect smoke impacts of variable intensity.
Due to decreasing fire operations, further updates will be issued only if warranted by a change in conditions.

Yosemite Bear Facts June 17 To June 30
2017 Total Bear Incidents: 3
2017 Total Property Damage: $450
Compared to this week in 2017 (the lowest year on record for bear incidents), bear incidents in 2018 are down by 63% and damage amounts (in dollars) are down by 39%.
Compared to this week in 1998 (when incidents in the park peaked), bear incidents in 2018 are down by 99%, and damages are down by 99.7%.
Bear Activity Summary: The beginning of June marked the first bear incidents in Yosemite including a bear damaging an unoccupied tent at the Crane Flat Campground, an unattended pack in Yosemite Valley and another pack at Lake Vernon. These incidents occurred because food or attractants (items that smell including in opened or unopened packaging) were left unattended.
Even with fewer bear incidents than usual, bear activity is still relatively high throughout the park. Bears have been reported in all major areas of the park, and much of the wilderness. When out hiking or camping in bear country, it is important to always keep food within arm’s reach or to store food properly in a sealed bear resistant canister or food storage locker.
Red Bear, Dead Bear: A bear was hit by a vehicle on the Glacier Point Road. Please help protect wildlife by obeying speed limits and being prepared to stop for animals in roadways. A map of bear-hit-by-vehicle hotspots, along with other Yosemite Bear Information can be viewed at:
Fascinating Bear Fact: Bears shed calluses on the soles of their feet when they hibernate, so when they first emerge from their den, a bear’s paws are very sensitive.
Please report bear incidents and sightings. Call the Save-A-Bear Hotline at 209-372-0322 or e-mail
Other Wildlife Sightings: This week marked the first fawns of the season being born in Yosemite Valley. Fawns are born relatively scentless and are camouflaged to hide from predators. When approached by a human their natural response is to remain still and silent, and try to hide. Adult female deer do not remain close to their fawns in order to prevent drawing attention to them, but do return throughout the day to nurse. If you find a fawn, keep your distance and do not approach it. It’s mother will be back for it. If you disturb or move a fawn, the mother will not be able to find it.  (C. Lee-Roney)
Inventories 2.0 Draft Plan Open for Review
The NPS Inventory & Monitoring Division (IMD) has completed the draft plan for Inventories 2.0 and is requesting review from NPS staff by July 20th. The plan can be reviewed using the Planning, Environment, and Public Comment (PEPC) website at Inventories 2.0 is the next generation of NPS inventories, and this draft plan is the result of scoping workshops and surveys that began in 2016, with input from over 800 NPS staff at the regional, network, and park levels. 
Joe DeVivo,  Deputy Chief of Science for IMD, thanks those who participated in the Inventories 2.0 scoping process over the course of the last year and a half. Participation in the review is voluntary, and your feedback is greatly appreciated. Your contribution helps the Inventory & Monitoring Division ensure the inventory data collected can be integrated into park management and planning.  (L. Mutch)
Where The Smoke's Coming From
As many may have noticed, the last couple of days have been really smoky. The Lion's Point Fire burning in the Ansel Adams Wilderness nearby is actually not the cause. The smoke is coming from the County Fire in Napa and Yolo County. Even though this is quite a distance away, it is not uncommon for smoke to travel long distances, especially during the summer months in the Western United States. The smoke is being carried by a northwest transport wind and settling in the valleys in the late night and early morning. This smoke may also get compounded with campfire smoke in Yosemite Valley. For people that are sensitive to smoke, please take precautions while recreating in the area; close windows and doors at night, drink plenty of water, and take all prescribed medication if you have pre-existing respiratory problems.

Lions Fire Morning Update 7-3-18
The Lions Fire is currently 3,850 acres and 50% contained. Yesterday’s burn-out operations were effective with good fuel consumption, resulting in strengthened fireline and reduced vegetation and dead and down wood throughout the burned area. Crews plan to complete the remainder of burn-out operations by hand today.
Smoke production from the Lions Fire is expected to be reduced today, and will continue to decrease throughout the coming week. Fires elsewhere in the region may affect air quality in the coming days. 
Nearly 20 miles of fire perimeter have been mapped for containment with handline or natural barriers, and air resources have logged approximately 680 flight hours. Operations are drawing down, and several crews and helicopters have been released to respond to other fires, regionally and nationally. Five crews currently remain on the fireline, and are focusing their efforts on the northern part of the fire.
This lightning-caused fire was detected in early June, and is located in the Ansel Adams Wilderness. It is located primarily in the Stairway Creek drainage, north and west of the Middle Fork of the San Joaquin River.
The following National Forest System Trails near the burned area have been temporarily closed: Sierra National Forest Trails No. 26E01 (Mammoth Trail) to the Inyo NF Boundary, 26E14, 26E56, and 26E46 from the Inyo NF boundary. Inyo NF trail closures include 26E01 from the Sierra NF to 2601 junction, and 2601 from the boundary of the Inyo NF and Devils Postpile National Monument (King Creek Trail). Trail closures will remain in place until fire management staff determines that it is safe to reopen the area for recreational use.
Shuttles to Devils Postpile National Monument and Reds Meadow Valley are running, and trails there are open. The Pacific Crest Trail and the John Muir Trail are open. Visitors should expect smoke impacts of variable intensity.
