APPENDIX 3-M
Background information for properfunctioning systems analysis.
I. Management Emphasis1 Categories
A. Ecosystem Management Emphasis Categories
Conservation (C) - planned management to prevent exploitation, destruction, or neglect.
A conservation emphasis assumes that the area of assessment has a dominant landscape compo-nent that is functioning relatively well as a native or naturalized system and is producing associ-ated human needs and values within the capabilities of the system. These landscapes generallyhave moderate to high ecological integrity and socioeconomic resiliency. Integrity is based onthe wholeness of elements and relationships of the primary ecological systems (geologic, geo-morphic, climatic, hydrologic, carbon-nutrient, food web, evolutionary, and toxins). There maybe inclusions (less than 20% of the area) with conservation or restoration emphasis.
*The geologic, geomorphic, pedogenic, climatic, hydrologic, and carbon-nutrient systemsare functioning similar to the native (HRV) system, and are shifting in a resilient manner tocurrent and potential future climate change and geologic events. Resilient change in re-sponse to climate change or geologic events would mean shirts in land forms (geomorphic),soil development (pedogenic), water flow or transpiration (hydrologic), and vegetation types(carbon-nutrient) that are in sync with the changes in climate and the geologic events (forexample, erosion rates would not be excessive or forest soils would not be developing ongrassland soils as climates changed to warmer conditions).
Terrestrial and aquatic systems (species and habitats) have a relatively complete array ofnative diversity. This does not mean that the composition is equivalent to native (HRV).However, the opportunity to manage for systems somewhat similar to native (HRV) shouldbe available.
A conservation emphasis assumes that relatively low management activity energy is needed foractive restoration of terrrestrial, aquatic, hydrologic, carbon-nutrient and pedogenic systemsbecause their current and future trends are relatively stable in response to disturbance andhuman effects.
A conservation emphasis assumes that human values and needs will flow from managementsystems that are designed to simulate the changes and disturbances that would occur within orrelatively close to native (HRV) patterns.
A conservation emphasis assumes that a coarse-filter strategy of managing landscape patterns ofsuccession/disturbance regimes similar to HRV will conserve and recover most native speciesdiversity. Stronghold or relic populations of threatened, endangered, candidate, or sensitivespecies may need short-term protection from disturbance of habitat that would occur in anHRV regime in order to expand the population to adjacent habitats.
1 The strategy of conserve, restore and produce as a basis for ecosystem management was developed by Jeff Blaclcwood and otherProject stafri based on the concepts in 'Forest Service Ethics and Course to the Future" by Jack Ward Thomas, and coordinatedwith BLM leadership.
Landscape Dynamics Appendix 3M-1Q41
Restoration (R) - to bring back to a former or original condition, pattern, or process.
A restoration emphasis assumes that the area of assessment has a dominant landscape compo-nent that is not functioning well as a native, naturalized, or non-native system and/or in theproduction of human needs and values within the capability of the system. Ecological integrityis usually low and socioeconomic resiliency is low or at risk. There may be inclusions (less than20% of the area) of conservation and restoration emphases.
*The geologic, geomorphic, pedogenic, climatic, hydrologic, and carbon-nutrient systemsare not functioning similar to the native (HRV) of the paleoecologic system, and are notresilient to current and potential future disturbance, climate change and geologic events.
Terrestrial and aquatic systems (species and habitats) are not functioning like native sys-tems. Generally the composition and structure will be well outside of native (HRV). Theremay be permanent alteration to biophysical potentials.
A restoration emphasis assumes that moderate management activity energy is needed for activerestoration of terrrestrial, aquatic, hydrologic, carbon-nutrient, and/or pedogenic systems be-cause their current and future trends are unstable in response to disturbance and human effects.Productivity may be at risk as well as increased risk of erratic disturbance events.
A restoration emphasis assumes that human values and needs will not flow from managedsystems unless there is active restoration to shift composition, structure, and disturbance to asystem that would be more consistent with native (HRV) patterns. It is likely that altered bio-physical systems cannot be managed for consistency with native (HRV) patterns because cause-and effect responses have changed. These systems will require a different type of management toprovide for resiliency and predictable response to disturbance, while conserving productivityand native diversity. Some processes and functions may be similar to native (HRV), while othersmay be different in order to account for the altered causes and effects.
A restoration emphasis assumes that a coarse-filter strategy of managing landscape patterns ofsuccession/disturbance regimes similar to native (HRV) will not conserve and recover nativespecies diversity. Active restoration of "lost" functions and species may recover the landscapesto a functioning condition that can then be managed with a conservation or production strat-egy. Stronghold or relic populations of threatened, endangered, candidate, or sensitive specieswill need protection from disturbance of habitat that would occur in or outside the native(HRV) regime in order to expand the population to adjacent habitats.
Production (P) - output of a commodity, value, or need.
A production emphasis assumes that the area of assessment has a dominant landscape compo-nent that is functioning relatively well as a native, naturalized or non-native system in associa-tion with traditional production of human needs, commodities, and values. Ecological integrityis usually moderate to high and as is socioeconmic resiliency. In some cases ecological integritymay be low and substantial mitigation is needed in order maintain trends to equilibrium.There may be inclusions (less than 20% of the area) of conservation and restoration.

in land forms (geomorphic), soil development (pedogenic), water flow or transpiration(hydrologic), and vegetation types (carbon-nutrient) that are in sync with the changes inclimate and the geologic events (for example, erosion rates would not be excessive or forestsoils would not be developing on grassland soils as climates changed to warmer conditions)such that they would not affect the capacity to produce human commodities, values, andneeds.
Terrestrial and aquatic systems (species and habitats) may or may not function like nativesystems. Generally the composition and structure will be well outside of HRV and theremay be permanent alteration to biophysical potentials. However the departure from native(HRV) and alteration of biophysical potentials does not affect the capacity to sustain humancommodities, values, and needs. The risks to productivity, current native diversity, andhuman values and needs caused by departure from native (HRV) system processes are rela-tively low in these systems, or high risks can be mitigated with increased management activ-ity.
A production emphasis assumes that relatively high management activity energy is needed foractive production of human commodities, values, and needs, while conserving the productivecapacity and current native diversity of the terrrestrial, aquatic, hydrologic, carbon-nutrient,and/or pedogenic systems.
A production emphasis assumes that human commodities, values, and needs will flow frommanagement systems with mitigation to conserve current native composition, structure, anddisturbance. The systems may not be consistent with native (HRV) patterns but they are man-aged consistent with biophysical potentials, not against internal system disturbance trends. Thiswill enhance the ability of the system to achieve multiple emphases of production, conservation,and restoration. It is likely that altered biophysical systems cannot be managed for consistencywith native (HRV) because cause-and-effect responses have changed. These systems will requirea different type of management to conserve productivity and provide for resiliency and predict-able response to disturbance. Active mitigation will be needed to conserve current native diver-sity. Some processes and functions may be similar to native (HRV), while others may bedifferent in order to account for altered causes and effects. Some systems may need to be artifi-cially supported to maintain or enhance production emphasis.
A production emphasis assumes that a coarse-filter strategy of managing landscape patterns ofsuccession/disturbance regimes similar to native (HRV) or with mitigation will conserve thecurrent native species diversity. Active restoration of "lost" functions and species may occur inassociation with some production activities to recover landscapes to a more native functioningcondition that will more efficiently achieve production objectives. Stronghold or relic popula-tions of threatened, endangered, candidate, or sensitive species will need protection from distur-bance of habitat that would occur in order to expand the population to adjacent habitats.
Restoration/Conservation (RC) - dominant component of the area is a landscape strategy forrestoration and conversion to conservation. The objective is to rapidly restore the area becauseof its adjacency to an area with a conservation strategy, that has an objective for expansion.
Restoration/Production (RP) - dominant component of the area is in a landscape strategy forrestoration, while producing at reduced levels. This strategy is designed to restore the area inorder to achieve a long-term strategy of sustainable production.
Landscape Dynamics
Conservation/Production (CP) - dominant component of the area is a landscape strategy forconservation, but with considerable opportunities for production of human commodities andvalues while maintaining ecological processes. This strategy is designed to conserve the areawhile producing sustainable commodities and values.
Mixed (MM) - the various conservation, restoration, and production strategies are mixedwithin the assessment area to achieve proper functioning systems with multiple ecosystemmanagement objectives for conservation, restoration, and production. This strategy is commonfor larger landscapes, subregions, and regions.
B. Traditional Management Emphasis Categories
Traditional Commodity (TC) - output of a commodity, value, or need.
A traditional commodity emphasis assumes that the area of assessment has a dominant land-scape component that is managed for traditional production of human needs, commodities,and values. Emphasis is on the multiple, but relatively independent management of variousresources (fire protection, timber, forage, recreation, wildlife, fisheries, and water) for sustainedyield of the resource.
*The geologic, geomorphic, pedogenic, climatic, hydrologic, and carbon-nutrient systemsare typically not functioning similar to the native (HRV) system. These systems are typicallynot responding in a resilient manner to current and potential future climate change andgeologic events.
*Terrestrial and aquatic systems (species and habitats) generally are not functioning as nativesystems. Generally the composition and structure will be well outside of HRV and theremay be high risk or actual permanent alteration to biophysical potentials. The departurefrom HRV and alteration of biophysical potentials often result in reduced production orrisk to production of human commodities, values, and needs. Attempts to mitigate for lossof system capabilities, reduced native diversity, and increasing risk of species extinctionstypically are unsuccessful or require very high investments of management activities.
A traditional commodity emphasis assumes that relatively high management activity energy isneeded for active production of human commodities, values, and needs with substantial em-phasis on protection to conserve current native diversity of the terrrestrial, aquatic, hydrologic,carbon-nutrient, and/or pedogenic systems. Energy invested in commodities and protection ofsystems is often precluded by disturbance events.
A traditional commodity emphasis assumes that human commodities, values and needs willflow from management systems that are often in conflict with ecological relationships andlandscape limitations. Mitigation is typically used to conserve current native composition,structure, and disturbance, but these efforts are often unsuccessful because of conflicts withecological relationships and landscape limitations. Most systems will need to be artificiallysupported to maintain commodity production, but the long-term outcome is typically a loss ofcommodity production capability.
A traditional commodity production emphasis assumes that a single species approach for recov-ery of threatened, endangered, candidate, or sensitive species is used to conserve current nativespecies diversity. Stronghold or relic populations of threatened, endangered, candidate, orsensitive species will be protected from human disturbance of habitats. However, these habitatsmay be at high risk to system disturbances as well as in conflict with other species habitats.
Landscape Dynamics
Traditional Reserve (TR) - protection of current native habitats, aesthetic values, and roadlessrecreation values.
A traditional reserve emphasis assumes that the area of assessment has a dominant landscapecomponent that is managed for protection of current native habitas, aesthetic values, androadless recreation values. Emphasis is on multiple, but relatively independent management ofvarious resources (fire protection, forage, roadless recreation, wilderness, wildlife, fisheries, andwater) for sustained yield of the resource.
*The geologic, geomorphic, pedogenic, climatic, hydrologic, and carbon-nutrient systemsare typically not functioning similar to the native (HRV) system. These systems are typicallynot shifting in a resilient manner to current and potential future climate change and geo-logic events.
*Terrestrial and aquatic systems (species and habitats) may be functioning to some extent asnative systems. Generally the composition and structure will be well outside of HRV andthere may be low to moderate risk of permanent alteration to biophysical potentials. Thedeparture from HRV often results in moderate risk of severe disturbance and potential lossof aesthetic values, native diversity, and biophysical potential. Attempts to mitigate for lossof system capabilities, reduced native diversity, and increasing risk of species extinctionstypically are unsuccessful because of the high cost of investments and lack of funds for thistype of land use management.
A traditional reserve emphasis assumes that low management activity energy is needed formanagement of human values and needs. However, substantial emphasis is required for protec-tion to control disturbance and conserve current native diversity of the terrrestrial and aquaticsystems.
A traditional reserve emphasis assumes that human values and needs will flow from manage-ment systems that are in conflict with ecological relationships and landscape limitations. Miti-gation is typically used to conserve current native composition, structure, and disturbance, butthese efforts are often unsuccessful because of conflicts with disturbance relationships andlandscape limitations. Most systems will need to be artificially managed to control disturbanceand provide protection to current conditions. The long-term outcome is typically a loss ofnative diversity and system capability.
A traditional reserve emphasis assumes that the protection of areas from disturbance and roadswill protect native species and habitats. A single species approach for recovery of threatened,endangered, candidate, or sensitive species is used to conserve current native species diversity.Stronghold or relic populations of threatened, endangered, candidate, or sensitive species will beprotected from human disturbance of habitats. However, these habitats may be at high risk tosystem disturbances as well as in conflict with other species habitats.
Traditional Mixed (TM) - mixed traditional commodity production is a mosaic with protection ofcurrent native habitats, aesthetic values, and roadless recreation values, where none of the types ofmanagement predominate in the area.

'Management Emphasis definitions:1) Conservation-- Emphasis provides for the protection of rare native elements and systems while maintaining proper func-tioning systems and restoring systems where there is low risk to rare elements or systems. Some human commodities may beproduced but the emphasis is on human values related to protection of native diversity, aesthetics, and recreation.2) Restoration- Emphasis provides for subsidizing ecological and landscape processes and functions to shift the transistiontoward proper functioning systems. Considerable human commodities may be produced that are compatible with restoration,as well as conservation of inclusions of rare elements and systems, but the emphasis is on shifting landscapes that are in highdeparture from the native regime toward proper functioning ecological relationships.3) Production— Emphasis provides for production of human needs and values by managing in concert with native ecologicaland landscape processes to maintain or shift to proper functioning systems. This will typically require subsidies to representnative ecological cause-and-effect relationships at landscape levels, along with some restoration and conservation, but theemphasis is on design of system responses that produce commodities and other values.4) Traditional— Emphasis on the independent managment model for producing commodity values, protecting visually orenvironmentally sensistive areas, or managing reserves to protect semi-primitive characteristics.

1 Prescription (Rx); see tables 3-M1 and 3-M2 for list of names and descriptions.2 Type of model:1) Native model refers to the patterns of ecological and landscape systems during the pre-Euro-American settlement system,which is synonymous with the historical range of variability (HRV) regime.2) Ecological model refers to management to transition to or maintain proper functioning systems (PFS), while producinghuman needs and values - given current conditions this infers that ecological and landscape processes and functions be subsidizedwith human technological energy in ways that are similar to native ecological cause and effects as controlled by landscape pro-cesses, while producing compatible human needs and values.3) Independent model refers to management for specific human values or needs in ways that are relatively independent of nativeecological and landscape cause and effect relationships.3 Management emphasis definitions:1) Conservation - emphasis provides for the protection of rare native elements and systems, while maintaining proper functioningsystems and restoring systems where there is low risk to rare elements or systems. Some human commodities may be producedbut the emphasis is on human values related to protection of native diversity, aesthetics, and recreation.2) Restoration - emphasis provides for subsidizing ecological and landscape processes and functions to shift the transition towardsproper function systems. Considerable human commodities may be produced that are compatible with restoration, as well asconservation of inclusions of rare elements and systems, but the emphasis is on shifting landscapes that are in high departurefrom the native regime toward proper functioning ecological relationships.3) Production - emphasis provides for production of human needs and values by managing in conceit with native ecological andlandscape processes to maintain or shift to proper function systems. This will typically require subsidies to represent nativeecological cause and effect relationships at landscape levels, along with some-restoration and conservation, but the emphasis is ondesign of system responses that produce commodities and other values.4) Traditional - emphasis on the independent management model for producing commodity values, protecting visually orenvironmentally sensitive areas, or managing reserves to protect semi-primitive characteristics.
