--- pcr_id: pcr.agriculture-forestry-and-fishery-products.forestry-and-logging-products.roundwood-of-coniferous-wood-sawlogs-and-veneer-logs language: en-US status: candidate sync_with: pcr.zh-CN.md --- # Coniferous sawlogs and veneer logs at roadside landing ## 1. Scope and Applicability This PCR covers coniferous roundwood selected for lengthwise sawing into lumber or railway sleepers, or peeling or slicing into veneer. The product is a raw log or bolt at a roadside landing, not sawnwood or a veneer sheet. Roughly squared logs, shingle or stave bolts, match billets, and specialty burls or roots are included only if selected for those uses. The official product boundary is in `unsd-cpc-03111` and `fao-forest-products-2020`. The foreground system includes attributable managed-stand activity, felling, extraction from stump to landing, delimbing and bucking at the actual route position, grading, and loading-ready roadside handover. A shortwood route may buck at the stump; tree-length routes may buck at the landing. Count the duty once. Road haul beyond the landing and mill-side sawing or veneer production are excluded (`fao-wood-harvesting`). Pulp/panel wood, poles and other industrial logs, fuelwood, non-coniferous logs, wood-processing residues, sawnwood and veneer sheets are outside the reference product. Downgraded logs sold to those markets are separately reported co-products of the harvest, not included in the sawlog/veneer-log reference volume. ## 2. Product Category Identity | Field | Value | | --- | --- | | canonical_pcr_id | pcr.agriculture-forestry-and-fishery-products.forestry-and-logging-products.roundwood-of-coniferous-wood-sawlogs-and-veneer-logs | | classification_refs | CPC 3.0:03111 exact — Roundwood of coniferous wood, sawlogs and veneer logs | | covered_products | Coniferous sawlogs, veneer logs, roughly squared logs, shingle/stave bolts, match billets and special veneer logs | | excluded_products | Pulp/panel wood; other industrial roundwood; fuelwood; non-coniferous logs; processed lumber and veneer | | representative_product | 1 m3 solid underbark of graded coniferous sawlog or veneer log ready for pickup at a roadside landing | | production_route | Managed stand → felling/removal → skidding, forwarding or cable extraction → delimbing/bucking at stump or landing → grading and roadside handover | | market_state | Raw round or roughly squared log/bolt; bark may remain physically attached, but reporting is solid wood volume underbark | The managed-stand parent may be naturally regenerated or planted. The latter changes seedling and site-preparation inventory only when those duties occurred. Motor-manual/mechanized felling and ground/cable extraction are alternative implementations of their parent activities; fuel, access and equipment records establish any delta. Routes can coexist among separate harvest lots but are mutually exclusive for a given stem segment. The route-specific bucking position is recorded (`fao-wood-harvesting`). ## 3. Reference Flow | Field | Value | | --- | --- | | What | Coniferous sawlog or veneer log graded for sawing or veneer use | | How much | 1 m3 solid wood volume underbark at the roadside landing | | How well | Declared conifer species, intended use, log grade, dimensions and bark convention | | How long or cycle | One identified harvest lot with its attributable stand phases, normalized to 1 m3; record harvest year | | reference_flow_link | `saw_veneer_log` | | Field | Value | | --- | --- | | Reference amount | 1 | | Reference product flow | Coniferous sawlog or veneer log at roadside landing; UUID unresolved | | Reference flow property | Volume `93a60a56-a3c8-22da-a746-0800200c9a66`; measured as solid wood volume underbark | | Reference unit group | Units of volume `93a60a57-a3c8-12da-a746-0800200c9a66` | | Reference unit | m3 | | Required qualifiers | species or mix; region and stand type; harvest system; log grade and intended use; length and diameter convention; underbark conversion; bark and moisture state; harvest lot/year; landing gate; co-product attribution | The foreground package must carry these qualifiers. The product-flow UUID remains unresolved. Confirmed Volume and volume-unit-group support identifies only the physical property and units, not the product state, gate or a product-flow match. ## 4. Measurement and Unit Rules | rule_id | Applies to | Required property | Required unit | Rule | | --- | --- | --- | --- | --- | | `underbark_volume` | Reference and all roundwood grade outputs | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 underbark | Use calibrated log-scale dimensions and a locally evidenced bark correction where needed. Do not equate stacked volume or tonnes to solid underbark volume (`fao-forest-products-2020`). | | `wood_balance` | Standing stock, felled stems, landing logs, grades and residues | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 underbark | Balance only matching wood components from the same lot under consistent bark, dimensional, moisture and volume conventions. Merchantable-stem input reconciles only with grades and stem losses originating in that input; branches, bark and other biomass outside it require separate component ledgers, not additional outputs in the stemwood balance. | | `fuel_basis` | Mobile and landing equipment | Fuel volume or energy; UUID unresolved | L or MJ | Preserve fuel type and lower-heating-value method; represent direct combustion once, not as upstream fuel production twice. | | `period_basis` | Tending and shared access | Physical service or area | ha, h, km or m3 | Attribute only dated activities benefiting the harvested lot. Never assume a universal rotation length. | | rule_id | Applies to | Required property | Required unit | Rule | | --- | --- | --- | --- | --- | | `provisional_range_evidence_policy` | all Ranges and actual exchanges | compatible property of each actual exchange | native unit of each actual exchange | All reasoned_estimate Ranges are provisional review prompts for this candidate method, not measured distributions, allowable losses, default quantities or emission factors. Never clip, backfill or force actual records to fit them; investigate state, units, boundary, stocks and evidence when exceeded. Before completing a data package, determine actual quantities and uncertainty from traceable measurements or applicable reviewed quantitative sources. Retain missing amounts, factors and flow identities as gaps that block completeness claims; passing a range screen is not evidence. | ## 5. System Boundary ### Boundary Abstraction | Field | Value | | --- | --- | | declared_starting_condition | `managed_conifer_stand_before_attributable_harvest` | | starting_condition_role | Declares the stand, region, management phase, legal harvest area and standing stock before attributable tending and removal. | | product_classification_scope | Coniferous sawlog/veneer-log grades only; other harvested destinations are separately identified co-products or retained residues. | | recursive_input_rule | Purchased coniferous logs are upstream products with separate datasets; never reopen this PCR recursively for that purchased input. | | upstream_dataset_requirement | Link purchased seedlings, fuels, electricity, lubricants, access materials and contracted services where they cross the boundary; model site combustion and land management once. | | disclosure | State forest origin, species, management phase, harvest system, bucking location, extraction distance, road/landing service, grading, bark and volume method, co-product destinations, residue fate, allocation and roadside gate. | ### Boundary Rules | rule_id | Applies to | Rule | source_ids | | --- | --- | --- | --- | | `boundary_roadside` | All lots | Include attributable stand management, felling, extraction, preparation and grading through loading-ready roadside handover; exclude road haul beyond landing and wood conversion. | `fao-wood-harvesting` | | `boundary_route_position` | Tree-length and shortwood routes | Locate delimbing/bucking at its actual stump or landing position and count input and residue duties once. | `fao-wood-harvesting` | | `boundary_residue` | Slash, bark and rejects | Marketed wood is a product, exported disposal material is waste, and slash retained in forest is a disclosed on-site loss rather than fictitious exported waste. | `fao-forest-products-2020` | | `boundary_shared` | Roads, landings and equipment | Attribute shared services across consuming operations and periods once, using recorded hours, area, road use or volume as appropriate. | | | `boundary_direct_release_coverage` | `stand_management`; `felling_removal`; `forest_extraction`; `log_preparation`; `grade_handover` | Reconcile on-site combustion, actual applications and fugitive releases/leaks at every activated node through unique activity-substance-receiving-medium records in cp_direct_release_stand_management; cp_direct_release_felling_removal; cp_direct_release_forest_extraction; cp_direct_release_log_preparation; cp_direct_release_grade_handover. Upstream production of purchased fuel or chemicals does not replace emissions from their use on site; verify coverage and avoid double counting the same activity inside a supplier service. Evidence must support non-activity; missing data are not zero. This obligation does not expand the existing product gate or downstream-use boundary and does not presume combustion, fertilization, chemicals or equipment occur. | | | `boundary_forest_carbon_land_coverage` | managed stand and purchased stand/wood interfaces | Before claiming a complete stand-to-roadside LCA inventory, select the applicable product-LCA accounting method and period and record one coverage/responsibility decision for land occupation, actual land transformation, above/belowground biomass, deadwood, litter, soil carbon and harvested-carbon transfer. Each relevant item needs compatible measured/modelled evidence, a named upstream coverage owner, or a method-justified exclusion with limitations. IPCC Forest Land identifies pools; its national inventory assumptions are not automatic product-LCA defaults. Do not infer carbon neutrality, gross uptake, net stock change or an uptake credit from reference-log carbon or wet underbark volume alone. Missing relevant land history, pool/time evidence or ownership blocks completeness. | `ipcc-forest-land-2006` | Select the route from actual incoming state and ownership. Qualified purchased harvested, extracted, prepared or graded feed may enter at its real receiving node; completed upstream operations are not mandatory foreground operations and standing stock or biological resources must not be charged again. Receiving cards record actual material, grade, wet/dry basis, receipt gate, upstream dataset and process coverage; add the actual receiving exchange if none exists. Bypass does not remove upstream burdens; actual operations cannot be skipped and final reference product, quality and gate remain unchanged. ## 6. Process Inventory Structure Inventory reporting and process measurement layers: card amounts are reported per 1 m3 reference flow; original quantities, same-lot process outputs, material states and period attribution remain individually recorded in collection protocols and calculation rules. Assign input burdens directly first and allocate shared burdens under Section 7. Preserve unallocated physical transfer and co-product ledgers, then divide each applicable lot amount by the positive final reference-product quantity of the same boundary and period; burden allocation must not shrink a material balance. Do not count internal transfers again as final outputs. Range blocks retain their explicitly declared original denominators: test process-output ranges locally before comparing any reference-normalized amount. If a Range must be converted, scale both bounds using the measured process-output/final-reference-quantity ratio and reviewed attribution factors applicable only to burdens, retaining original bounds and evidence; never assume this ratio is one. Each energy carrier, fertilizer formulation, material and substance keeps its own unit; unlike units cannot be summed. The final reference output is accepted lot quantity divided by itself; rejects, packaging and non-reference grades are excluded from its denominator. Determine activation from stand, task and lot records; distinguish unused activity from missing data. Energy, fertilizer and other inputs require separate cards for distinct actual flow identities within each process. Retain carrier, formulation and supply specifications and verify each applicable identity before dataset use. Independently required product states, handoffs and destinations remain separate. Measure fuel by mass, electricity by electrical energy and services in their reference unit, retaining documented density for volume conversion; do not apply one quantity range to L, kg, kWh and h. Same-lot output/input handoffs share a compatible material identity, with process gate retained in lot records. A generic platform flow may be used where its scope is compatible and foreground records carry the required qualifiers; absence of species in a flow name or a Mass property alone is not grounds for rejection. ### Process Map | process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference | | --- | --- | --- | --- | --- | --- | | `stand_management` | Stand management | conditional | Only when actually inside the foreground; qualified purchased completed-state feed bypasses completed operations while retaining upstream burdens. | Produces identified standing timber stock before felling. | harvestable stem m3 underbark and dated stand phases per reference m3 | | `felling_removal` | Felling and removal | conditional | Only when actually inside the foreground; qualified purchased completed-state feed bypasses completed operations while retaining upstream burdens. | Independently removes stemwood from standing stock; hands felled stems to extraction. | felled-stem m3 underbark per reference m3 | | `forest_extraction` | Forest extraction to roadside | conditional | Only when actually inside the foreground; qualified purchased completed-state feed bypasses completed operations while retaining upstream burdens. | Transfers felled stems or shortwood to landing, not to mill. | landing-stem m3 underbark per reference m3 | | `log_preparation` | Primary delimbing and bucking | conditional | Only when actually inside the foreground; qualified purchased completed-state feed bypasses completed operations while retaining upstream burdens. | Converts raw stems to measured logs and identifies trim, bark and loss. | prepared-log m3 underbark per reference m3 | | `grade_handover` | Grading and roadside handover | required | Sort every prepared log by use and grade. | Separates saw/veneer reference logs, downgraded products and disposal rejects. | m3 underbark per grade and destination per reference m3 | Route order is exclusive per stem segment. Shortwood follows felling → forest-site delimbing/bucking → extraction of prepared shortwood → roadside grading. Tree-length follows felling → extraction of tree-length stems → landing delimbing/bucking → roadside grading. The display order of process nodes is not a common operational sequence for both routes. ### Process: Stand management (`stand_management`) Node `stand_management` must complete the direct-release coverage reconciliation in `cp_direct_release_stand_management`. Expand each actual substance/medium into an output elementary exchange at this node with a measured or evidence-calculated amount; link existing emission cards to the same event record rather than duplicating them. Distinguish non-occurrence, verified upstream-service coverage and missing evidence; an empty elementary-flow group does not satisfy this requirement. #### Inputs ##### Product flows ###### Coniferous seedlings for planting (`conifer_seedlings`) Activate only for recorded planting or replanting.

Allocation and Co-product Handling | rule_id | Applies to | Rule | source_ids | | --- | --- | --- | --- | | `allocation_output_set` | Grading and shared harvest | Tally sawlog and veneer-log grades, pulp/panel logs, other industrial logs and fuelwood where marketed; give each destination one handover and measured underbark volume. Keep rejected waste and retained slash separate from intended products. | `fao-forest-products-2020` | | `allocation_shared_activity` | Shared stand, felling, extraction and landing burdens | Assign directly metered activity to the receiving grade where feasible; otherwise allocate common harvest activity among marketed wood outputs by measured solid underbark volume at the common gate. No avoided-product credit or burden allocation to retained slash. | | | `allocation_period_assets` | Stand phases, roads, landing and machines | Index establishment, tending, thinning and harvest activity by stand and year. Attribute shared assets to benefiting lots using actual area, machine hours, road service or measured output before the grade split. Carry only the share benefiting future harvests forward; never count one burden twice. | | | `physical_ledger_before_allocation` | Physical ledgers and attributed burdens | Retain unallocated physical values for original material balances, handoffs and co-products: q_B = Q_B/R. Apply this PCR's allocation method separately to shared burdens: b_ref = B_shared * a_ref/R; assign direct burdens directly and apply each period/output share once. R is the selected final reference output, excluding internal transfers. Never apply burden share a_ref to original co-product or transfer quantities; distinguish any allocated single-product process projection from the unallocated whole-package material ledger. | | Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness. ## 8. Foreground Data Collection, Calculation, and Quality Rules ### Specific input identification before dataset completion Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange. Before dataset completeness, represent each used material, formulated product, carrier or independently purchased service by one physically specific card with its native quantity/property; confirm a compatible UUID, or retain an explicit unresolved identity and do not claim a fully linked dataset. Do not substitute a conditional example for an unknown actual input, invent a recipe, omit required use or infer zero from missing records. Attribute shared use, reusable assets and inclusive services once; preserve the original stage/period and measured throughput link to final reference output.

Keep occupation in area-time, transformation as from/to area events, carbon as kg C on a stated dry basis. Retained slash remains a source-pool/fate record, not automatically an exported product or waste; disclose any relevant later decomposition responsibility. | ha; ha-year; kg dry matter; kg C | inventory and event; period reconciliation | full declared accounting period | represented stand/source | attribute compatible totals once, then normalize to declared reference output | source maps; compatible pool records; original method; allocation and coverage ledger | ### Calculation Rules | rule_id | Applies to | Formula or rule | Inputs | Output | source_ids | | --- | --- | --- | --- | --- | --- | | `calc_underbark` | Every wood stream | Apply documented calibrated log-scale formula and locally measured bark correction before aggregation; never use a universal bark percentage. | length, diameters, bark, scale method | m3 solid underbark by lot and grade | `fao-forest-products-2020` | | `calc_wood_balance` | Harvest through grading | For the matched merchantable-stem pool, V_open + V_felled + V_purchased = V_marketed + V_removed_stem_waste + V_retained_stem_loss + V_close + delta, on a matched lot-specific solid underbark basis. V_purchased is actual harvested/prepared wood received from outside the reconciled foreground system, excluding own wood already in V_felled and internal transfers; a purchased-only route may have V_felled=0. Delta is only a signed unexplained measurement residual to disclose and investigate: known stock changes are explicit, not delta or emissions. Retained loss must originate in that input pool; branches, bark, special root/burl wood and other excluded components use separate compatible physical ledgers. Cancel paired internal transfers once at whole-package aggregation. | component-indexed felling and external receipt records; opening/closing stocks; grade and loss origins; matched scale records | volume balance by lot | `fao-forest-products-2020` | | `calc_reference` | Final-reference normalization of physical ledgers and environmental burdens | R is positive accepted saw/veneer-log solid underbark volume (m3) for the same lot, boundary and period; downgraded co-products and internal transfers are excluded from that denominator. Report unallocated material, transfer and co-product totals Q as q_phys = Q/R. For environmental burdens B only, complete evidenced direct, period, output and asset attribution once, then report b_ref = B_attributed/R. Do not apply burden shares to physical ledgers or divide already final-reference amounts again. | unallocated physical ledger Q; environmental burdens B; evidenced attribution; matched reference quantity R | amount per 1 m3 reference output | `reference-normalization-identity` | | `calc_shared` | Management and shared assets | Attribute actual dated service to benefiting stands/lots once using measured service drivers, then split common lot burden among marketed roundwood grades by underbark volume. | dated operations, service driver, lots, grades | activity attributable to reference grade | | | `calculate_direct_release_ledger` | `stand_management`; `felling_removal`; `forest_extraction`; `log_preparation`; `grade_handover` | For each unique event, substance and medium, obtain raw release E from measurement or the cited applicable method using activity A and a compatible factor EF; use E = A * EF only for a genuinely simple-factor method, after checking units and abatement scope. Do not add different substances/media; retain an unallocated raw-release ledger. Divide attributed burden totals once by matched positive final reference quantity R; do not renormalize final-reference intensities or allocate a shared event twice. Unexplained material residuals are not automatically emissions and missing factors are not zero. | cp_direct_release_stand_management; cp_direct_release_felling_removal; cp_direct_release_forest_extraction; cp_direct_release_log_preparation; cp_direct_release_grade_handover; existing emission cards; supplier coverage; reference quantity | Node/substance/medium-specific raw and attributed amounts and unresolved gaps | | | `calc_forest_carbon_land` | land, pools and upstream ownership | Distinguish gross uptake, releases, harvest carbon transfer and net stock change under the chosen method; never sum stock-change and gain/loss approaches for the same pool/period. Resolve wet volume to dry mass and carbon only with compatible density/moisture/carbon-fraction evidence and correct component scope. A log carbon balance is not a whole-forest pool balance. Attribute land and carbon quantities to the declared period and output once; keep any upstream stand coverage and purchased-wood transfer ownership without double counting. No automatic sequestration credit or fixed forest-neutrality assumption. | `cp_forest_carbon_land` | method-specific land/carbon quantities and explicit completeness gaps | `ipcc-forest-land-2006` | ### Data Quality Requirements | requirement_id | Applies to | Requirement | Evidence | | --- | --- | --- | --- | | `dq_log_trace` | Every log and grade | Link stand, harvest lot, species, grade, intended use and destination to dispatch. | permit, log scale and docket | | `dq_scale` | Wood volume | State scale method, calibration, bark conversion, moisture and dimensional convention; flag inconsistent units. | scale and conversion worksheet | | `dq_route` | Harvest route | State extraction method and bucking position; count every machine duty and output once. | machine and operation log | | `dq_period` | Stand and infrastructure | Record establishment/tending/harvest phases and serviced years, disclosing missing historical records. | management and road-use logs | | `dq_balance` | Inputs, grades and residues | Reconcile all marketed and retained destinations and disclose residual volume differences or missing fuel data. | grade tally and fuel reconciliation | ## 9. Validation Rules | rule_id | Applies to | Rule | source_ids | | --- | --- | --- | --- | | `validate_product` | Reference output | Require conifer species, saw/veneer intended use, raw log state and roadside gate; reject lumber, veneer sheets and pulp/other/fuel logs as the reference. | `unsd-cpc-03111`; `fao-forest-products-2020` | | `validate_unit` | Reference and wood grades | Require 1 m3 solid underbark reference and documented local conversion for overbark, mass or stacked-volume records. | `fao-forest-products-2020` | | `validate_route` | Process map | Require evidenced harvest and extraction system, one bucking position per stem segment and no duplicate extraction/preparation burdens. | `fao-wood-harvesting` | | `validate_destinations` | Landing grade tally | Require one grade, destination, handover and underbark volume for every saw/veneer, pulp/panel, other industrial, fuelwood or rejected stream present. | `fao-forest-products-2020` | | `validate_rework` | Downgraded and rejected wood | No automatic rework loop is assumed. If an actual lot is regraded or recut, track that operation once and prevent its earlier rejected state from also appearing as accepted output. | | | `validate_attribution` | Shared and multi-period activity | Verify phase-to-lot and asset-to-consumer drivers, direct assignment before common volume split, no burden on retained slash and no double attribution. | | | `validate_uuid` | Final TIDAS exchanges | Resolve each concrete exchange to exactly one verified flow UUID with matching flow type, direction, property, unit and use before process projection; unresolved cards are not fixed bindings. | | | `validate_card_activation_units` | All refined cards | Verify activation and actual material/formulation/task/supply specification; missing records are not zero. Each amount and Range uses one compatible property/unit; retain density and wood mass/volume bridges. Check contractor-service components against fuel, equipment and emissions to avoid double burdens. | `fao-wood-harvesting` | | `validate_direct_release_coverage` | `stand_management`; `felling_removal`; `forest_extraction`; `log_preparation`; `grade_handover` | For every activated node, reconcile its activity list against cp_direct_release_stand_management; cp_direct_release_felling_removal; cp_direct_release_forest_extraction; cp_direct_release_log_preparation; cp_direct_release_grade_handover: each relevant event must have quantified concrete elementary exchanges, evidenced upstream-service coverage, or evidenced absence of the activity. Missing/unknown is not zero and blocks data-package completeness. Check each actual substance/medium amount, method/factor units, concrete UUID and existing-card/service coverage for omissions or duplication; empty groups, purchased-electricity upstream emissions or another node's single CO2 card do not replace this node's on-site reconciliation. Shared-asset services must not create duplicate physical release events. | | | `validate_forest_carbon_land_coverage` | stand boundary and source responsibility | Require the selected LCA method/period, pool and land applicability decisions, traceable compatible evidence/exclusions and unique coverage ownership before completeness. Unknown or missing relevant pool/history/time/unit evidence fails the completeness claim; do not interpret missing data as zero or borrow national Tier-1 defaults without justified product-LCA applicability. | `ipcc-forest-land-2006` | - Reconcile required/conditional activation and upstream coverage against incoming state at each node; purchased completed-state feed must not duplicate growth, harvest or preparation. Equal classification does not replace state and gate matching. ## 10.
