Don't Trash That Slash! Reaping Value From NM's Forest Residuals
 

Don't Trash that Slash! was a collaborative project of the New Mexico Recycling Coalition (NMRC) to promote the value of creating compost and mulch from forest thinning projects. Through a grant from the U.S. Forest Service's Collaborative Forest Restoration Program, NMRC teamed with a dynamic group of organizations and industry experts to give forest and land managers the knowledge and access to resources to realize the value of composting and mulching chipped forest residuals.

 

The New Mexico Recycling Coalition (NMRC) managed this US Department of Agriculture Forest Service Collaborative Forest Restoration Program (CFRP) grant from August 2005 to July 2008.  The project increased awareness about the value of mulch and compost as a forest waste by-product and its application for erosion control and soil protection. Awareness regarding the value of mulch increased via numerous outreach and education efforts, including workshops, presentations, one-on-one consultations and demonstration projects. The project’s target audience consisted of forest managers and personnel, tribes,  forest thinning contractors, CFRP recipients, public land management agencies and forestry students and youth working in Wildland Urban Interface (WUI) projects.

Mulch Applications Identified:

Through this grant, NMRC identified the following uses for mulch:

  • Erosion Control
    • At all application depths, woodchips have proven less erodible than straw as a surface mulch material, particularly on steep slopes (Meyer et al. 1972)
    • An untreated soil surface produces 50 times more sediment than a mulched surface (Demars et al., 2001)
  • Landscaping and Vegetation Establishment
    • Reduces runoff and improves infiltration as water has more time to seep in
    • Helps to maintain soil moisture between rainfall events
  • Project Mitigation
    • Reduces the visual and physical impacts of thinning project(s)
  • Lop and Scatter
    • This is a surface treatment similar to mulching with branches, in which the slash is manually distributed across the treated area without chipping or masticating to reduce the particle size.
  • Compost Creation
    • Wood chips are an excellent source of carbon for composting projects
  • Roadside Applications
  • Assists with re-vegetation and erosion control efforts

 

Monitoring the Effects of Wood Mulch Applications -

As part of the effort to promote the beneficial use of forest residuals, NMRC conducted monitoring to quantify the effects of wood mulch application on vegetation, soil moisture, and soil temperature in a variety of Southwestern landscapes. Soil moisture and temperature were measured continuously at the sites with in-situ sensors attached to data loggers. Monitoring locations were chosen based on implementation schedules, accessibility, and the relevance of the project and location. Sites were intended to represent areas most likely to receive similar treatments statewide. Four principal settings were identified for inclusion in the monitoring program; roadside, piņon-juniper, ponderosa, and invasive-dominated riparian. Four sites were established and equipment was installed during 2007. Permanent photo points were installed in conjunction with the monitoring equipment to provide visual documentation of changes at each site.  Table 2 denotes site activities for each monitoring site. In addition to the four monitoring sites, composting and erosion control activities were documented and evaluated at two demonstration sites.

Benefits of Creating Compost and Mulch

from Chipped Forest Residuals

 

*Less prescribed burn risk and associated air quality impact

*Conditions soil and controls erosion

*Promotes water retention and revegetation

*Promotes better water quality by controlling surface run-off pollution

*Creates value-added, sustainable product

 

 

 

Case Study in Compost and Mulch Application1: New Mexico Department of Transportation

Compost and mulch are incredibly valuable as an erosion control application and are currently being used in NM Department of Transportation (NMDOT) roadside reclamation and re-seeding projects, which presents a potentially large value-added market for forest residuals. Read on for an overview of compost and mulch applications by NMDOT in road construction projects.

 

2000: The first roadside reclamation site implementing composted mulch occurred at the northeast interchange quadrant of I-40 and I-25 in Albuquerque.  Subsequently three other 4,000 sq. ft. test sites were implemented near Santa Fe (Budagher’s exit of I-25), Encino and Carrizozo. In each case compost was applied with native grass seed and plant growth was successful.

 

2002-2003: Practically overnight, the Pine Bark Beetle infestation caused huge Pinon tree die-offs, generating large quantities of green-waste at northern New Mexico transfer stations and landfills. NMRC, NMED SWB, NMDOT, private compost businesses and municipal agencies worked together to establish a consistent market for the increased volumes of mulch and compost. Building on a compost reclamation program developed by the Texas Department of Transportation, NMED and NMDOT developed standards for mulch and compost applications on New Mexico highway projects.

 

2004 & 2005: Additional demonstration sites in Santa Fe on Highway 599 and along South Broadway in Albuquerque were completed successfully. NMDOT utilized compost on official roadside projects along US 70, I-40, and US 84/285, and will continue to specify and apply compost in upcoming roadside reclamation projects.
