Tuolumne Meadows Lodgepole Pine Removal: 7/31 – 8/17
CCC crews and volunteers will be removing lodgepole pine saplings in the Tuolumne Meadows area until 8/17. Cut material will be piled along the roadside to be chipped. Lodgepole pine encroachment is present in many parts of Tuolumne Meadows due to shifting climatic conditions and other anthropogenic factors. This has consequences for meadow vegetation composition, wildlife communities, downstream ecosystem services, and the visitor experience. Once established, lodgepole pine will persist unless restoration actions are taken. (K. Russell)

The Knowledge Fair will include a demo of the Memento field data collection app and a presentation on recent scanning projects undertaken by Design & Engineering Facilities Management. Contact Elizabeth Hale for a calendar invite. (E. Hale)

Pika Fire Update 8/2/23
Location: Just west of North Dome

Elevation: 7,100’

Discover date: June 29, 2023

Size: 841 acres

Containment: 60%

Cause: Lightning

Yosemite Fire crews are using a management strategy utilizing natural barriers and trails to confine the spread of the fire in a predefined area. A confine and contain strategy under favorable conditions allows fire to move naturally across the landscape, providing ecological benefits to plants and wildlife, while also meeting protection objectives to minimize risk to people and infrastructure.

Fire management in Yosemite provides for the reduction of hazardous fuels, increasing the diversity of habitats, promoting new plant growth and a return of a natural fire cycle to the landscape.

Trail closures are still in effect for trails on Indian Ridge and within the Pika Fire burn area, Lehamite Creek Trail and the southern trail to North Dome are now open. Areas of unburned fuel remain active northwest of North Dome. Crews will remain onsite to ensure the fire stays within the current perimeter and will continue to monitor for the coming weeks.

Smoke from the Pika Fire is expected to impact Yosemite Valley in the evenings and overnight with conditions improving as smoke lifts during the late mornings. Slight impacts may also be seen on trails near the fire including in Yosemite Valley.

For current smoke conditions:

In that case, the gates will remain closed, and signs will be posted at the two closure gates that the trail is closed.

Hikers and backpackers headed to Little Yosemite Valley, Half Dome, and points beyond from the trailhead at Happy Isles may hike uphill on the Mist Trail if they reach the Mist Trail/JMT junction by 7:00am, Monday through Thursday. Otherwise, they must hike the JMT. (W. Weaver)


The Merced Grove is Closed for Restoration

Giant sequoias are adapted to frequent, low-intensity fire and depend on fire for reproduction. Frequent fires reduce fire intensity by thinning the forest of small and unhealthy trees and reducing the accumulation of dead branches and trees. But over the past century, fires were suppressed, and drought and insects killed millions of trees in Yosemite. In the Merced Grove, there is limited sequoia regeneration and fuel loading has increased to dangerous levels. Currently, we cannot safely introduce fire without first mechanically removing fuels first. Since 2020, wildfires have killed almost 20% of mature giant sequoias across their range due to extreme fuel loading, and we aim to prevent that outcome in the Merced Grove. Therefore, we are removing small diameter conifers, hazard trees, and dead and downed wood to reduce wildfire risk to the sequoias and firefighters as preparation for the first prescribed fire in and around the grove. The grove will be closed for 2.5 months during the restoration for visitor and worker safety. Please contact with questions or for access. (G. Dickman)


Wawona and Yosemite Valley Wildfire Protection Project

As part of an ongoing hazardous fuels reduction project to protect communities, increase forest resilience, and decrease risk to firefighters and the public, small trees and dead and down wood will be removed in Wawona and Yosemite Valley. In Wawona, material north of the south fork of the Merced River on NPS land and private property through a partnership with Mariposa County Resource Conservation District. In Yosemite Valley, crews will be working along North Side Drive between Middle Brother and El Capitan picnic area and between El Capitan woodlot and Pohono Bridge. Actions within Yosemite Valley are in preparation of prescribed fire. Material is either piled to be burned later or transported for carbon capture where it is used for wood products, electricity generation, or used as fill in restoration projects. (G. Dickman)


Valley-wide Continuous Flow Intersection Improvement Project

Sentinel Drive remains closed for construction as the FHWA contractor pours and finishes concrete for pedestrian improvements at the site of the abandoned bus stop and Sentinel Drive parking area. Granite masonry work continues thru the week beginning July 17. Asphalt pavement patching is scheduled for the week beginning July 24. The contractor is also working on construction of traffic diverters (or raised medians) at the valley chapel parking area and Sentinel Drive intersections at Northside and Southside Drives. Completion of work depends on the readiness of labor and availability of equipment and materials. (J. Donovan)


Yosemite Valley Shuttle Bus Stop Improvements

The NPS contractor continues work at seven sites for new pavement construction in Yosemite Village, Curry Village, and on Happy Isles Loop. Disruption and delays in traffic circulation are to be expected. The contractor is authorized to conduct traffic control operations Monday through Thursday. (J. Donovan)


Electric Vehicle Supply Equipment

The contractor has completed work in Wawona and in Yosemite Valley. However, vehicle chargers are not available until the units can be energized and commissioning is complete. Until further notice, working charging stations are limited to eight at Yosemite Valley Lodge, two at the Ahwahnee Hotel, one at the Village Store, and two between the El Portal market and gas station. (J. Donovan)


Dispatch Expansion Project

The Dispatch Expansion project will convert most of the El Portal Warehouse lobby into office space for the Emergency Communications (Dispatch) Center. The lobby area is an active construction zone and therefore is off-limits to non-construction workers. To access the Dispatch office area, follow the signs in through the Trails area door just inside the fence/gate. Warehouse occupants and visitors need to use alternate means of ingress/egress until that portion of the construction is finished. Do not enter through the RMS building unless you work there. Expect intermittent construction noise throughout the project, which is scheduled to be completed in September of 2023. Contact Nicole Belle Isle, Project Manager, for more information. (N. Belle Isle)


Riverbank Restoration Between Sugar Pine Bridge and Ahwahnee Bridge, June through August

The Vegetation and Ecological Restoration branch will be conducting riverbank restoration work between Sugar Pine Bridge and just past Ahwahnee Bridge from June-August. This project will remove riprap from the riverbank, plant willows and other native species, and install an engineered log jam at one location on the riverbank to enhance riparian habitat and mitigate the effects of Sugar Pine Bridge on the Merced River. This restoration project is part of the Merced Wild and Scenic River Management Plan, which aims to reverse some of the past human impacts to meadows and riverbanks, to protect and enhance river values, and to promote public access and enjoyment of the river.
