Texas Forest Service Resource Specialists Learn About BMPs

Recently-hired resource specialists got a chance to learn about water quality protection issues during a workshop in Hudson.

Forester Todd Thomas and Resource Specialist Bernie Buckner led the class to expose the new employees to Best Management Practices.

“The BMP training helped newer staff learn how to help mitigate water quality issues while they’re working in the forest,” said Forester Todd Nightingale. “They will be able to use what they learned to assist forest landowners with information, and it will help make them more proficient at fireline rehabilitation operations after wildfires.”

Participants got to install waterbars and learned how to manage site disturbances to reduce impacts to local waterways.

May BMP Q&A

By: Chuck Coup, BMP Forester (Ret.), Texas Forest Service

Q:   In recent months the outbreak of wildfires and the threat of wildfires occurring has been high.  I want to protect my timber from a possible wildfire by installing firelanes around my tract.  Are there any BMPs that I should follow during this project to prevent any impacts on water quality from occurring?

A:   Installing firelanes around your timber is a great way to protect your investment by reducing the threat of a possible wildfire.  Firelanes work by creating a barrier and removing the available fuel source between adjoining stands or tracts.  By removing the fuel source along these barriers aids in preventing a wildfire one stand or tract to another.  However, it is important to remember that there are potential impacts to water quality that can occur if caution is not taken. 

Guidelines for properly constructing and maintaining firelanes can be found in the Texas Forest Service’s BMP Bluebook.  These recommendations are designed to prevent any unnecessary erosion form occurring thus minimizing the potential for impacts on water quality. 

Firelanes should be constructed along the perimeter of the tract and follow the boundaries of Streamside Management Zones.  Locating these barriers outside of SMZs will limit the amount of sedimentation that may result.  This will also protect the litter and organic matter of the SMZ so it can continue to serve as a filter.    

To allow for proper drainage and erosion control, waterbars and wing ditches should be installed in a timely manner.  Recommendations for installing these devices can be found on pages 34 and 38 of the BMP Bluebook.  These recommendations include how to properly build waterbars, proper spacing for waterbars, and specifications on properly installing wing ditches.  When installing wing ditches, make sure that the runoff water is not being discharged directly into streams.    

Regular maintenance on firelanes is necessary to avoid potential erosion problems.  This includes periodic inspections, especially after heavy rains, to make sure that they are still functioning properly and are not washed out.  Mowing, rather than blading, is the preferred type of maintenance because it minimizes the amount of exposed mineral soil.  Care should be taken when blading is the only option. 

Implementing these control structures can be very costly when using heavy machinery.  For economical as well as environmental reasons, it is important to only build firelanes as wide and deep as necessary.  Woody debris and other flammable material should be kept away from firelanes.  These objects can ignite, creating a pathway for the fire to spread into SMZs or adjoining lands.  If you have a question regarding BMPs, please call me at (936) 639-8180.

August BMP Q&A

By: Chris Duncan, BMP Forester (Ret.), Texas Forest Service

Q:   I have a tract of timber which was clearcut last fall.  The logger who harvested the tract did a bang up job on installing necessary BMPs where they were needed.  My consulting forester has recommended that I conduct a site preparation burn later this summer to prepare the site for planting.  The tract has a stream on it that usually runs for about 3 months in a typical year.  Are there any special BMPs in regards to prescribed burning that should be implemented to ensure the water quality of the stream is not adversely affected?

A:   Glad to hear that you were happy with the job your logger did in implementing BMPs where they were needed.  Prescribed burning can be a beneficial management tool when used properly with trained personnel. Site preparation burns are often the hottest type burn and can remove a substantial amount of the surface organic material. This type of burn would have the greatest potential for increased surface runoff or soil erosion, particularly on steeper slopes.  Use the following guidelines to help reduce the risks to water quality and soil erosion on your tract.

Site preparation burning creates the potential for soil movement.  A significant amount of soil movement can be caused by the preparation for the burns, i.e., firebreaks. Firebreaks should have water control structures that divert runoff away from water bodies in order to minimize erosion.  Site prep burns on steep slopes or highly erodible soils should only be conducted when they are absolutely necessary and should be as "cold" as possible.  Stabilize and revegetate firelines, if needed, on grades in excess of 5% or areas subject to accelerated erosion or known sensitive areas.

Firelines should be constructed on the perimeter of the burn area and along the boundary of the Streamside Management Zone (SMZ). The purpose of protecting the SMZ from fire is to safeguard the filtering effects of the litter and organic matter.  All efforts should be made to minimize the impact from site-prep burning within an SMZ.  Firelines should follow the guidelines established for logging trails and skid trails with respect to waterbars and wing ditches, and should be only as wide and as deep as needed to permit safe site preparation burns.  Firelines which may cross a drainage should be turned parallel to the stream or have a wing ditch or other structure allowing runoff in the line to be dispersed rather than channeled directly into the stream.

Finally, make plans to maintain your firelanes after the burn has been completed.  Firelanes on highly erodible sites or other problem areas should be inspected periodically to correct erosion problems by installing dips, wing ditches, waterbars, etc. and/or by seeding.  Mowing, rather than blading, should be used to maintain firelanes in order to avoid exposing mineral soil to potential erosion.

September BMP Q&A

By: Hughes Simpson, BMP Forester, Texas Forest Service

Q:   After seeing the devastation caused by the Moore Branch and Chicken fires in East Texas last year, I would like to protect my timber investment from this possible hazard.  In order to do this, my forester has recommended that I install firelanes around my property. I am concerned about the possible erosion that may occur from the exposed soil. What can I do to prevent this from occurring? What other BMPs do I need to keep in mind when doing this?

A:   Installing firelanes around your timberland is an excellent way to reduce the threat of a wildfire.  These artificial barriers are used to stop the spread of fire by removing their fuel source.  Thousands of miles of these structures are built every year in Texas to prevent these disasters from taking place.  It is important that landowners realize the potential impacts that firelane erosion can have on water quality.  

The Texas Forest Service has published guidelines that address proper firelane construction and maintenance in the Texas Forestry Best Management Practices – Bluebook.  These recommendations are designed to prevent any unnecessary erosion from occurring on this type of forest management.

Firelanes should be constructed along the perimeter of the tract and follow the boundaries of Streamside Management Zones.  Locating these devices outside of SMZs will limit the amount of sedimentation that may result.  This will also protect the litter and organic matter of the SMZ so it can continue to serve as a filter.    

To allow for proper drainage and erosion control, waterbars and wing ditches should be installed in a timely manner.  Charts on pages 35 and 37 of the BMP Handbook show the recommended spacing between these structures.  When installing wing ditches, make sure that the runoff water is not being discharged directly into streams.   

Regular maintenance on firelanes is necessary to avoid potential erosion problems.  This includes periodic inspections, especially after heavy rains, to make sure that they are still functioning properly and are not washed out.  Mowing, rather than blading, is the preferred type of maintenance because it minimizes the amount of exposed mineral soil.  Care should be taken when blading is the only option. 

Implementing these control structures can be very costly when using heavy machinery. For economical as well as environmental reasons, it is important to only build firelanes as wide and deep as necessary. Woody debris and other flammable material should be kept away from firelanes.
