CO - Trail Inventory Gap Resolution Project
« on: April 18, 2007, 05:42:06 pm »

Hello All,
You are receiving this email because you are a member of COHVCO and/or expressed interest in learning how to help inventory roads and trails in Colorado via GPS.  Attached is a letter explaining what the TIGeR Team project is and how it works (TIGeR stands for Trail Inventory Gap Resolution).  The second attachment is a questionnaire that we would like you to fill out and return to **if you are interested in becoming a TIGeR Team member.  The GPS project the TIGeR Teams will be working on will be state wide, and you will receive information on how to GPS the trails accurately in order for the project to work effectively.  Please refer to the letter for further details.

Thank you all for supporting COHVCO!

Dear Interested TIGeR Team Member,

Thank you for offering to help save our OHV roads and trails.  In November 2005 the U.S. Forest Service was directed to create a designated system of roads and trails on all national forests and grasslands.  This process is a part of the Travel Management Rule.  The Travel Management Rule allows for public collaboration in identifying and recommending those routes for designation.  You need to be aware that this process is not absolutely uniform from forest to forest.  The Travel Management Rule culminates in a Motor Vehicle Use Map (MVUM).  The MVUM will be derived from the agencies baseline existing roads and trails.  There are at least two ways for the agency to arrive at the publication of this map.  The first approach allows the forest to use existing decisions involving routes that are either open or closed from which they may directly create the MVUM, placing them in full compliance with the Travel Management Rule.  The second approach allows the forest to use GPS to add important historical roads and trails to a data base roads so they may be considered for future designation.

For our purposes the most important approach involves the second outlined above, and we have two types of participation and are seeking volunteers at this time.  The first type is the creation of GPS data information on existing, well documented, important, historical roads and trails that do not appear on the agencies baseline inventory of roads and trails.  As a potential volunteer for our project, your role in this instance is to help build this database so that the routes identified by you, although not currently open, may be considered under future travel management decisions.  In short we are creating an undeniable record that these routes existed, were used, and should be considered in the future.

The second role that you can play involves participation in active Forest Travel Management planning.  The Gunnison National Forest is a prime example of this approach.  Some forests will go directly to the publication of the MVUM, however forests like the Gunnison will be open for GPS data information to be considered in conjunction with the development of their new Travel Management Plan.  As you can see, these routes you identify can be open as a part of the plan.  Once the plan is completed then the MVUM will be published.

Now that you have a basic understanding of why GPS data on roads and trails is critical to collect, allow me to introduce you to the TIGeR Team concept.  TIGeR stands for Trail Inventory Gap Resolution.  This letter is to start the creation of these teams. The intent is to cover all Forests in Colorado. After several meetings with the Forest Service, we have derived a system and format in which the Forest Service will accept this information.

Volunteers are needed for the TIGeR Teams across the state.  Ideal candidates will possess some of the following: 
* Knowledge of the majority of trails in a specific area; historic knowledge is a plus
* How to read the latest Forest Service map to see where the gaps in data occur
* Know how to use a GPS to gather trail information
* To possess the capability to gather the needed information by legal means if a road or trail is a non-motorized route (ex. by foot, horseback, mountain bike, etc.)
* Utilize the educational DVD provided by NOHVCC or COHVCO (at no charge) to learn the procedure
* Include audio or written detail support of the GPS routes as stated in the DVD
* Know how to download that GPS information in the format required and transfer it to the person collecting it for preparation for the Forest Service
Most of the communication in this process will take place via the computer.

If you have not already received the training DVD, you can order it by contacting the NOHVCC (National Off Highway Vehicle Organization) at 1-800-348-6487 or e-mail them at

COHVCO is in the process of obtaining from the Forest Service the official baseline "system" trail maps for each National Forest.  The maps should show all of the roads and trails which will be considered "open" for OHV use.  Each forest and/or Ranger District has determined what its deadline to create the MVUM will be.  Some Forests are further along in the process than others, so all of the maps may not be available at the same time.  The baseline maps COHVCO will be receiving from the Forest Service will be the most current data on existing "system" trails.

As a TIGeR Team member you will be heavily involved in the process of collecting route information and partnering with the local ranger district.  Partnering and collaboration are the keys to making this a successful project and it will be critical at every step to ensure that all parties involved understand what will occur, how it will occur, when it will occur and where.

In order for you to help with the TIGeR Team project you need to decide what region or riding area you can cover and you will need to learn how to prepare your information for the person that will be organizing it and sending it to the Forest Service via e-mail (again - view the DVD for details).

There will be several scheduled training classes to assist individuals in learning the necessary steps of the involved process.  The NOHVCC Colorado Route Designation Workshop is scheduled for April 26-29 in Colorado Springs, CO (www.nohvcc.orghas the registration information, and the conference is free for all to attend).  COHVCO is also in the process of putting together a schedule of training classes (

If you are interested in becoming part of the TIGeR Team project and can provide this service, please contact the TIGeR Team project managers ASAP so we can start the process.  The TIGeR Team project managers will coordinate the collection of trail and road data, and assist in keeping as many miles of roads and trails open in Colorado.
