Fire Restoration | El Dorado National Forest

An ACE California crew of 4 just completed a 7 day project creating erosion control structures in an area impacted by the King and Power Fire just east of the Hell Hole Reservoir in the Sierra Nevada mountain range, CA.

The aim of this project was to improve hydrologic function within the King Fire and Power Fire burn areas by increasing ground cover with burned trees or other natural material, and by removing ground disturbances that affected hydrologic conductivity. Activities include falling dead trees to increase in-stream coarse wood, and some stream bank reconstruction.

Sawyers strategically felled trees across slopes where structures were needed. Rounds were cut and placed where water had already began to erode the stream bank, and in areas where a lack of vegetation would lead to a high possibility of erosion during winter months.

Jack Colpitt explained that his favorite part of this project was the opportunity to learn more about the complex process of felling trees, and also the tree identification exercise.

The King and Power Fire was a human-caused fire that started on September 18, 2014. The fire burned 97,000 acres and caused hundreds of people to evacuate their homes.

ACE staff would like to extend a special thanks to Wade Frisbey for joining us on this project to assist with the technical cutting.

Canoe Trail Restoration, Congaree National Park

News of a very unique and interesting project from ACE Southeast. Crews there are actively involved in the restoration of over 14 miles of popular canoe trails in Congaree National Park, near Hopkins, South Carolina.

That’s right, canoe trails. ACE has become somewhat synonymous with trail building and trail maintenance in the deserts of the Southwest, but this is a first, conducting canoe trail maintenance. As we geographically expand so does the scope of our expertise.

The ACE crew, led by its fearless leader Isabel Grattan, is using primitive hand tools to clear the popular Cedar Creek Canoe Trail that travels through the heart of Congaree National Park. Cedar Creek is a major part of the dynamic floodplain wilderness area of the park and passes through a primeval old-growth forest which contains some of the tallest trees in eastern North America. The marked trail winds approximately 15 miles through the Congaree Wilderness, starting at Bannister’s Bridge and going all the way to the Congaree River.

Downed trees and log jams are a common occurrence on Cedar Creek. The ACE corps members paddle 2-4 miles a day in their two-person canoes and use cross-cut saws, hand saws, and loppers to clear away large trees and debris that have fallen over the creek during the previous late summer and winter storms. This work is vital in improving the conditions for park visitors who would otherwise need to portage around these obstacles.

Congaree National Park was established in 2003 and is home to many champion trees (largest of their species) and a wide variety of reptiles, amphibians, as well as fish-eating spiders. Paddling the Cedar Creek trail is arguably the best way to experience the Park.

Hazard Tree Removal in Los Alamos, NM

A crew of 5 ACE sawyers just returned from a project removing 2 miles of hazard tress which posed a risk to ski trails around the Pajarito Mountain Ski Area in New Mexico. This area had been affected by the 2011 Las Conchas Fire which burned 150,000 acres and threatened the Los Alamos National Laboratory and the nearby town of Los Alamos. After five days of burning it became the largest wildfire in New Mexico’s history, although this record was broken in 2012 and the Whitewater-Baldy Complex Fire.

So what makes a tree a ‘hazard tree’? The US Forest Service describes a hazard tree as ‘…a tree with structural defects likely to cause failure of all or part of the tree…” Effectively, hazard trees are dead but remain standing. They pose a danger to the public as they can fall without warning. It is therefore important to remove them from the vicinity of the trail, or ski run, to ensure the safety of the public.

ACE sawyers are selected for Hazard Tree Felling based upon several criteria: Positive feedback from project partners and ACE Crew Leaders, demonstrating that they are interested and capable of progressing their saw skills, and, most importantly, having ample experience with the saw so that they can complete hazard tree cutting techniques safely and efficiently.

The hazard tree training includes a review of different tree species that they may find, tree fiber structures and their effects on the felling of a tree, how to size up a complex tree, advanced cutting techniques and cuts, cut selection, and advanced wedging techniques. It’s also important the sawyers know a ‘walk away situation’ – a tree that cannot be safely felled at that time.

At the Pajarito Mountain Ski Area the ACE sawyers felled a total of 109 hazard trees over 9 days, helping to secure the area in advance of the 2015 ski season.
