Recreation Opportunity

Spectrum (ROS)

 

 

The following table reflects information contained in

FSM 2330.3; the Recreation Opportunity

Spectrum Color Poster (R6-REC-118-94); and

ROS Primer and Field Guide (R6-REC-021-90).

The color matrix shows by ROS Setting the kind

of “on-site development” that can be considered

“normal,” “fully compatible,” “inconsistent,” or “unacceptable.”

 

Note:

* Native refers to materials found naturally in nature. It needn’t come from or near the project site.

** Synthetic materials should not be used in primitive settings. Where possible, they should be avoided in semi-primitive settings, but if used, they should not be evident to the user. In roaded natural settings, native materials are usually used, and synthetics, if used, should not be evident to the user.

 

Legend

“Normal” describes “normal” conditions found in the ROS Setting

“Fully compatible” describes conditions that meet or exceed the norm for the ROS setting

“Inconsistent” describes conditions not generally compatible with the normal setting conditions, but which may be necessary under some circumstances to meet management objectives. The more removed from the “norm” shown in the above matrix, the more questionable the condition would be. For example, a pit toilet acceptable in a Semi-primitive Non Motorized setting would be very questionable in a rural or urban setting. Use of metal or plastic siding or roofing that appears obviously synthetic to a visitor would be inconsistent in a roaded natural setting.

“Unacceptable” describes conditions that, under any circumstance, do not permit the creation or maintenance of an ROS Setting, and which will cause a change in that setting towards one that is more developed. For example, moderate or heavy site modification and development of facilities for user comfort would change a primitive ROS setting into one that is more developed.

 

Figure of a matrix of the relationship of ROS Settings to On-Site Development.

In the Primitive ROS the following is “Normal”, and is “Fully Compatible” with Semi-primitive Non Motorized and Semi-primitive Motorized ROS:

No facilities for user comfort; rustic and rudimentary ones site protection only.

Synthetic materials excluded.

Use undimensioned native materials only.

No site modifications for facilities.

A higher degree of development is either “Inconsistent” or “Unacceptable” in the Primitive ROS.

 

In the Semi-primitive Non Motorized and Semi-primitive Motorized ROS the following is “normal” and is “Fully Compatible” with Roaded Natural ROS:

Rustic and rudimentary facilities primarily for

site protection. Use undimensioned native materials. Avoid use of synthetic materials.

Little or no site modifications

for facilities. Limited and subtle site modification.  A higher degree of development is either “Inconsistent” or “Unacceptable” in the Semi-primitive Non Motorized and Semi-primitive  Motorized ROS. A lower degree of development is “Inconsistent” with Roaded Natural ROS.

 

In the Roaded Natural ROS the following is “Normal” and is “Fully Compatible” with Rural ROS:

Rustic facilities providing some comfort for the user

as well as site protection. Contemporary/rustic

design usually based on use of native materials.

Synthetic materials should not be evident.

Moderate site modifications.

A higher degree of development is either “Inconsistent” or “Unacceptable” for Roaded Natural ROS. A lower degree of development is “Inconsistent” with Rural ROS.

 

In the Rural ROS the following is “Normal” and is “Fully Compatible” with Urban ROS:

Some facilities designed primarily user comfort and

convenience. Some synthetic but harmonious materials

may be incorporated.  Design may be more complex and

refined.  Moderate to heavy site modifications for facilities.

A higher degree of development is “Inconsistent” for Rural ROS. A lower degree of development is “Inconsistent” with Urban ROS.

 

For Urban ROS the following is “Normal”:

Facilities mostly designed for user comfort and

convenience.  Synthetic materials are commonly

used.  Facility design may be highly complex

and refined but in harmony or complementary to

site.  Heavy site modifications for facilities.

 

The following example describes typical ROS settings as described in the “1986 ROS Book.”

Acreages and distances described may vary somewhat between regions.

 

PRIMITIVE

Generally, it is on a setting of at least 5,000

acres and 3 miles away from all roads and trails

with motorized use (or has sufficient spatial or

topographic characteristics to allow a sense of

solitude). Access is via non-motorized trails or

cross country. Very low interactions with other

visitors. Very high chance of solitude; unmodified

natural or natural-appearing environment.

 

SEMIPRIMITIVE NONMOTORIZED

A setting that has an area of primitive roads* or

trails that are not open to motorized use; is

generally at least 2,500 acres in size; and is

between 1/2 and 3 miles from all roads, railroads,

or trails with motorized use. Access is via

nonmotorized trails or nonmotorized primitive

roads or cross-country. Low contact frequency

with other visitors. High probability of solitude;

natural-appearing environment.

Note:* “Primitive roads” are not constructed or maintained and are not generally suitable for highway type vehicles.

 

SEMIPRIMITIVE MOTORIZED

A setting that has an area that allows motorized

use, is generally at least 2,500 acres in size, and

is at least 1/2 mile from a better than primitive

road.** It is within 1/2 mile of primitive roads or

trails used by motor vehicles. Access is via

motorized trails or primitive roads or crosscountry,

where terrain and regulations permit.

Low to moderate contact frequency with other

visitors. Environment may have moderately

dominant alterations, but these do not dominate

views from trails or primitive roads in the area.

Note: ** “Better than primitive roads” are constructed or maintained for the use of highway type vehicles.

 

ROADED NATURAL

A setting in an area that is within 1/2 mile of a

better than primitive road. Access is primarily

via conventional motorized use on roads.

Contact frequency with other users may be

low to moderate on trails and moderate to high

on roads. Environment is natural appearing as

viewed from visually sensitive roads and trails.

 

RURAL

Predominantly a culturally modified setting

where the natural environment has been

substantially modified, i.e., structures are readily

apparent, pastoral or agricultural or intensively

managed wildland landscapes predominate as

viewed from visually sensitive roads and trails.

Access is primarily via conventional motorized

use on roads. Contact frequency with other users

may be moderate to high in developed sites and

moderate away from developed sites.

 

URBAN

Urbanized environment with dominant structures,

traffic lights, and paved streets. Access is

highly intense, motorized, and often with mass

transit supplements. Contact frequency and

interaction with large numbers of people is high.

Recreation places may be city parks and large

resorts.

 

 

The following table matrices show in gray shading those portions of the ROS where the well-designed use of material described at the left is either “normal” or “fully compatible.” Where not shaded, material use may be “inconsistent” or “unacceptable.” Note that Roaded Natural (RN) was enlarged to show more detail, reflecting both the widespread nature and importance of this setting in the national forest built environment. As a rule of thumb, when one-third or less of a setting is shaded, use the material with caution. Check first with FSM direction to determine suitability of certain improvements, e.g. shelters and play equipment.
