Understanding Active & Passive Recreational Uses – Part 2

6/19/2018

In part 1 of this series, we discussed what active and passive recreational uses were and how they are defined.

As we discussed, to be a passive use, the activity would have to meet 3 criteria:
  1. Have no greater impact than other passive uses
  2. Use the same recreational facilities as other passive uses
  3. Can occur with other passive activities and users simultaneously

As point #2 illustrates, it’s not only the activity, but the infrastructure of that recreational use that would be a factor in determining if an activity could be considered passive or active.  The example used in the previous article was that of a football field and a multi-use trail.

However, if we have a trail, in this case multi-use, could an activity come along might not be passive use?  And where does mountain biking, as an activity, fit in with the idea of active and passive use?

That will be some of the questions we will answer in this second part.

​Unfortunately, it gets kind of complicated

Can a new use be added to passive recreational use infrastructure that is active recreational use?  Clearly, the answer is yes.  If you go back to the original legal definition, it includes the fact that passive recreational activities are non-motorized.  Therefore, any activity that includes motors, from dirt bikes to drones, by default is active recreational use.  That also includes e-MTBs, which can be a sore point.

To qualify for passive recreational use, the activity would have to check all three of the above boxes.  If it fails to meet one of the three, it falls into the active recreational use column.  That means different versions of the same activities could be either passive or active.  Walking or running along a trail would be passive use, but some kind of obstacle course with various structures would be active use as it would fail 2 of the 3 tests: it would have different infrastructure than other passive use and it’s hard to see how other passive recreational users and people scaling a wall or swinging on ropes are compatible.

That gets us to mountain biking: is it active or passive recreational use?  Well, it’s both and that is where complications start.  Depending on the type of mountain biking, the answer to those three questions would change.  And that means this isn’t a yes or no question.

Issues with “no greater impact than other passive uses” – Many mountain bikers, when asked, will tell you that mountain biking and hiking have similar impacts.  That is a true statement, but a functionally incorrect one.  Why can that be said?  The studies that have been done on mountain biking and sustainable trails are almost exclusively on one type of trail: cross country (XC) trails that are built and maintained to sustainable standards (i.e. IMBA 2004/USFS 2007).  If we get outside the borders of that description, the amount of evidence we have of a similarity of impacts drop off and drops off fast.  Clearly, when talking about disciplines like downhill or freeride mountain biking, one doesn’t need a study to know the resulting impacts of movement are higher than other passive uses.  These disciplines have steeper trails, greater speeds and greater braking forces.  That means more soil movement.  That isn’t even considering other factors.  Therefore, these uses don’t meet the criteria of passive use.  What about adventure courses or all-mountain/trail/enduro/whatever we are calling it now?  Depending on the factors below, those uses might be passive or they might be active recreational use.

Issues with using “the same recreational facilities as other passive uses” – For over a decade now, there haven’t been separate construction guidelines for hiking trails, mountain biking trails, or multi-use trails.  So, on the surface, it would seem that this one is buttoned up.  However, if you think about it, the recreational facilities for downhill or freeride would not meet these criteria.  The jumps, drops and other parts of the trail required would qualify as active use facilities.  Adventure courses would meet this criterion, as long as these would be placed on existing paths of use.  Clearly, cross county (XC) mountain biking would.  Again, all-mountain may or may not fit these criteria.  It would depend on any number of on-site factors.

Issues with accommodating “other passive activities and users simultaneously” – This is probably the  contentious of the three.  What we are referring to here is the factual ability of a trail to accommodate differing types of users simultaneously, not the perceived ability.  That means someone whose day is ruined because they saw a mountain bike in the woods isn’t the determining factor.  Its whether or not that person is placed in an unsafe space by the other activity or he is unable to do his own passive activity.  As we’ve discussed before, for hikers, speed and sightlines are the determining factor.  This is where, again, freeride and downhill, just fail to meet this criterion.  Adventure courses would always meet this criterion.  Cross country (XC) mountain biking can meet this criterion, though it’s not automatic.  User management techniques and trail layout need to be used to ensure that situations compromising another user’s safety don’t exist.  For the third time, all mountain could go either way depending on the factors of the trail.

To recap, the active vs. passive breakdown for mountain biking looks like this:

Active Use

Passive Use

Freeride

Downhill

All-Mountain (dependent; on-site factors)

Cross Country

Adventure Courses

All-Mountain (dependent; on-site factors)

​Let’s walk though this

​Remember the table we used in Part 1 to show the three questions of passive vs. active recreational use?  Let’s show it again and then walkthrough how cross county mountain biking would qualify for the listed properties.  The table:
 Item

Active Use

Passive Use

Infrastructure

Requires specialized infrastructure

Requires no specialized infrastructure

Maintenance

Requires specialized maintenance on said infrastructure; often with fossil fuel burning equipment

Requires no specialized maintenance on said infrastructure; often uses hand tools or human action only

Use

Often requires an exclusive use of the area occupied

Other passive uses can use the area occupied at the same time

Environmental Alterations

Most involve the removal of natural vegetation & topography; often indirectly removing wildlife

Only seeks the removal of natural vegetation & topography as required for infrastructure; limits impact to wildlife

Material Alterations

Often adds non-native or invasive species or materials to a locality

Uses only native and natural species and materials in its use and infrastructure

Wildlife Alterations

Directly or indirectly displaces wildlife

Minimizes any displacement of wildlife; mostly while humans are present in that area

​Now, using a bullet, list let’s work though the cross-county mountain biking:
  • Requires no specialized infrastructure
    • Mountain bike trails are built to a guideline called “IMBA 2004”. This stands for “International Mountain Bike Association (IMBA)” and the date that IMBA published a textbook/workbook entitled “Trail Solutions: Your Guide to Building Sweet Singletrack”. This textbook/workbook teaches how to build sustainable trails for mountain biking.
    • In 2007 the United States Forest Service (USFS) adopted 100% of IMBA’s trail building techniques for its own trail building guidelines. Often you see this standard combined in description as “IMBA 2004/USFS 2007”.
    • Because almost all states and cities across the United States reference their trail building standards to the United States Forest Service standards, any trail built to the USFS 2007 guidelines would be, in fact, built to IMBA 2004 guidelines.
    • Hence, mountain biking trails are not specialized infrastructure. In fact, technically speaking, there are not mountain biking trails and hiking trails. Just sustainable trails that can be used for a variety of human powered activities from hiking to trail running to mountain biking.
  • Requires no specialized maintenance on said infrastructure
    • There is no such thing as maintenance free sustainable trails. Entropy affects all things, including trails. Sustainable trails will require regular maintenance. Most post-construction maintenance for sustainable trails is done with hand tools by volunteers.
    • Many cities with sustainable trails make upkeep of those trails a requirement for those trails to remain open.
  • Other passive uses can use the area occupied at the same time
    • Across the United States, municipalities that have urban sustainable trails overwhelmingly use those trails as multi-use trails of some type. Almost all municipalities use some kind of user management techniques to ensure all users can interface stress-free on multi-user trails. The most common of these strategies is directionality, which is defining the direction different user groups travel on trails.
  • Only seeks the removal of natural vegetation & topography as required for infrastructure; limits impact to wildlife
    • IMBA 2004/USFS 2007 style trails are very narrow infrastructure. For a standard machine-built (mini-excavator) trail the typical impact width is less than 48”. Since there are only one set of sustainable trail guidelines, if built by a machine, that width would be the same regardless of the usage.
    • Before any dirt is moved or vegetation cut, trail corridor alignments are inspected by municipal personnel (or contracted experts) in the fields of biology (such as wetland delineators, arborists, botanists or zoologists), geology and sociology & historic concern. If any of these inspections reveal issues, the trail alignment is tweaked/moved as required to minimize or eliminate these issues. Trails are buffered from impacts to wildlife as needed.
  • Uses only native and natural species and materials in its use and infrastructure
    • Whenever possible sustainable trails seek to use available materials for any structures (steps, armoring) as part of the trail.
    • Where structures like boardwalks or bridges are required, rough-sawed, non-treated, rot resistant wood is used.
    • Pavement, gravel or other forms of impervious coverage are avoided at all cost.
  • Minimizes any displacement of wildlife
    • As discussed above, at the construction phase attempts are made to avoid or minimize any impacts to the flora and fauna at the location of the trail. Wildlife is a broad category and what may minimize impacts for one species might exacerbate them for another species.
    • Generally, urban mountain biking trails allow riding sun-up to sun-down and do not allow night riding. Some do allow night riding, but only at certain times of the year when nocturnal creatures are less likely to be out and about (i.e. winter riding).
    • Some trails close during certain times of the year if the land its one is used as bird nesting site or mammalian birthing site.

What this means

Simply put, it means one thing: when the property is defined by its need to have passive recreational uses within said property, then  the only forms of mountain biking that would qualify would be cross country (XC), adventure courses and (depending on specifics of trail layout/design) all-mountain.  For urban wildernesses, preserves, natural areas and greenways this should be the only type of trails that should be proposed in these locations.  For locations that allow active uses, such as multi-modal parks or  post-industrial areas, then any type of mountain biking could occur.

In the end, knowing what active and passive recreational use actually are  helps to know where mountain biking , as an activity, can go.  That is important, as the goal of urban riding is to create a diversified cornucopia of riding venues, trail types and experiences close to citizen's homes.
