Restoration Solutions, LLC was contracted by Catron County to implement restoration treatments on ten stands dispersed throughout the county. Eight of the stands were on private land and two were located on Forest Service land, yielding a total number of 121 treated acres. The elevation ranged from 7,500 to 7,800 feet with an estimated annual precipitation of 12 to 16 inches. This project was unique and especially interesting because of one of its primary purposes – to demonstrate the volume of biomass harvested from each specific treatment type.



The ecotypes included in this project were similar to those that surround the future site of a 35-megawatt biomass power generating plant in Estancia, NM. This project was designed to determine the volume of biomass that could reasonably be generated from each of the treatment types in order to assess the viability and sustainability of the fuel supply for the power plant. Since the market for the biomass was not yet established (construction had not started on the power plant as of September 2008), the material was broadcast on site and used for erosion control on pre-existing problem areas.

Restoration Solutions utilized a variety of mechanical equipment to implement the treatments, including a rubber-tired feller buncher, skidsteer buncher/shearer, extractor (excavator), skidsteer with bucket and grapple rake, skidder, and horizontal tub grinder. The extractor pulled the trees, roots and all, from the ground, leaving slight depressions to catch precipitation and seeds. One landowner took the opportunity to plant Kentucky bluegrass in the depressions, which already shows signs of growth.

 

  

The private landowners were extremely pleased with the treatment outcomes and were only sorry that more acres could not be treated. At one site visited in mid-March, multiple bird species were identified including ferruginous hawk, pygmy nuthatch, Clark’s nutcracker, Steller's jay, and western bluebird. Elk were also spotted nearby, with evidence suggesting that they were moving in to the newly treated areas due to the increased visibility.

 Treatment Specifics
 18Primary treatment objective
Reduce fire danger, restore ecosystems, and determine biomass volume harvested from these types of treatments.
 
 19How does biomass removal fit with other objectives?
No nearby existing market for dirty chips, so they were broadcast on site.
 
 20Treatment description
Varies per stand type, utilizing NM Restoration Principles and BMP's to restore to previous ecotype.

 
 21Description of contractors
Mechanized thinning operators
 
 22Travel distance for contractors
40 to 200 miles depending on treatment area
 
 23Type of equipment used
Rubber-tired feller buncher, skidsteer buncher shearer, extractor (excavator), skidsteer w/ bucket & grapple rake, skidder, horizontal grinder
 
 24Treatment of residual slash if any
All material was chipped on site and broadcast
 
 25Treatment cost per acre
$789
 
26Trucking costs

 30Did biomass markets exist previous to project?
No, this project was part of the development of local markets for large-scale biomass utilization.
 
 31Type of utilization
None (except on-site erosion control and mulch)
 
 32How well did the woody biomass match the utilization options?
No nearby existing market for dirty chips, so they were broadcast on site.
 
33Distance to utilization

 
 Treatment guidelines, targets, limitations
 34Diameter limit
Ponderosa pine: 9" dbh; pinon and one-seed juniper: 18" or 24" depending on ecosytem type
 
 35Basal area reduction
50-60%
 
 36Crown coverage

 
 37Fuel loading

 
 38Retention guidelines
Keep all ponderosa pine >9" dbh; leave minimum 20' spacing between residuals in dog hair pine area; retain all Pinon and One-seed Juniper > 18" and 24" depending on ecosystem type.
 
 39Treatment of snags and downed logs
Left on site
 
 40Soil impacts
no more than 15% impact by skid trails and landings, definitly exceeded that since new operator and some compaction (some in-progress feedback given to improve operations
 
41Other ecological impacts monitored
Utilized chips as mulch where pre-existing erosion evident
