National Core Field Guide, Version 6.1 October, 2014 FOREST INVENTORY AND ANALYSIS NATIONAL CORE FIELD GUIDE VOLUME I: FIELD DATA COLLECTION PROCEDURES FOR PHASE 2 PLOTS Version 6.1 National Core Field Guide, Version 6.1 October, 2014 Changes from the Phase 2 Field Guide version 6.0 to version 6.1 Changes documented in change proposals are indicated in bold type. All of the changes relating to damage codes were approved using the change proposal system of incorporating changes to the damage code list annually. These change pages are intended to highlight significant changes to the field guide and do not contain all of the details or minor changes. 1.12 FIELD GUIDE VERSION. Changed the Values from “6.0” to “6.1”. 5.7.1 RECONCILE. In codes 3 and 4, added the following text: “Includes previously nonsampled subplots.” 5.20.1 DAMAGE AGENT 1. Added the following text to the procedure: “Note: in some cases, thresholds for specific agents may be different from the threshold for the corresponding general agent. If a region is collecting a specific insect agent and no one is collecting the general agent, then the specific insect agent is collapsed into the general insect category 10000.” Under Values, added the following text to code 13000 in column 2: “Note: this is only collected by IW and SRS.” Appendix 11. Damage Codes. The sixth column heading was changed from “New Category?” to “General Category Designation”. The following changes were made to the appendix: Code Old Threshold New Threshold Old REGION New REGION 11012 Any evidence of a NRS successful attack. 12005 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 12029 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 12047 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 12048 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 12068 Any occurrence NRS 12086 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 12136 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 12197 Any occurrence NRS 12200 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 13010 Any damage to the SRS terminal leader; 2 National Core Field Guide, Version 6.1 October, 2014 Code Old Threshold New Threshold Old REGION New REGION damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 14001 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 14033 Any occurrence NRS 15001 Any damage to the terminal NRS leader; damage ≥20% of the roots, stems, or branches 15004 Any damage to the terminal NRS leader; damage ≥20% of the roots, stems, or branches 15026 (no change) SRS SRS; NRS 15031 Any damage to the terminal NRS leader; damage ≥20% of the roots, stems, or branches 15065 Any damage to SRS terminal leader; damage to > 20% of lateral shoots and buds 15088 Any damage to the terminal NRS leader; damage ≥20% of the roots, stems, or branches 17011 Any damage to the terminal NRS leader; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 22011 Any occurrence NRS 22075 Any occurrence NRS 22076 Any occurrence NRS 22002 Any visual evidence 22003 Any visual evidence 25022 Damage ≥20% of the PNW foliage with ≥50% of the leaf/needle affected 25057 Damage ≥20% of the NRS foliage with ≥50% of the leaf/needle affected 25072 Damage ≥20% of the NRS foliage with ≥50% of the leaf/needle affected 26002 Any occurrence on the bole PNW or stems (on multi- stemmed woodland species), or on branches ≤1 foot from boles or stems; damage to ≥ 20% of branches 41001 Any damage to the terminal PNW 3 National Core Field Guide, Version 6.1 October, 2014 Code Old Threshold New Threshold Old REGION New REGION leader; damage ≥20% of the roots or boles with >20% of the circumference affected; damage > 20% of the multiple-stems (on multi-stemmed woodland species) with >20% of the circumference affected; >20% of the branches affected ; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected. 41002 (no change) SRS SRS; PNW 41003 (no change) IW IW; PNW 41004 Any damage to the terminal PNW leader; damage ≥20% of the roots or boles with >20% of the circumference affected; damage > 20% of the multiple-stems (on multi-stemmed woodland species) with >20% of the circumference affected; >20% of the branches affected ; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected. 41005 (no change) IW IW; PNW 41006 (no change) IW IW; PNW 41007 Any damage to the terminal PNW leader; damage ≥20% of the roots or boles with >20% of the circumference affected; damage > 20% of the multiple-stems (on multi-stemmed woodland species) with >20% of the circumference affected; >20% of the branches affected ; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected 41008 Any damage to the terminal (no change) leader; damage ≥20% of the roots or boles with >20% of the circumference affected; damage > 20% of the multiple-stems (on multi-stemmed woodland species) with >20% of the circumference affected; >20% of the branches affected ; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected. 41009 Any damage to the terminal PNW leader; damage ≥20% of the roots or boles with >20% of the circumference affected; damage > 20% of 4 National Core Field Guide, Version 6.1 October, 2014 Code Old Threshold New Threshold Old REGION New REGION the multiple-stems (on multi-stemmed woodland species) with >20% of the circumference affected; >20% of the branches affected ; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected. 41015 Any damage to the terminal PNW leader; damage ≥20% of the roots or boles with >20% of the circumference affected; damage > 20% of the multiple-stems (on multi-stemmed woodland species) with >20% of the circumference affected; >20% of the branches affected ; damage ≥ 20% of the foliage with ≥ 50% of the leaf/needle affected. 90010 (no change) ALL IW; PNW; NRS 5 National Core Field Guide, Version 6.1 October, 2014 Changes from the Phase 2 Field Guide version 5.1 to version 6.0 Changes documented in change proposals are indicated in bold type.

Made the following changes: Old text New text 0 General Description 0 General Description 1 Plot 1 Plot Level Data 2 Condition 2 Condition Class 3 Subplot 3 Subplot Information 4 Boundary 4 Boundary References 5 Tree Measurements 5 Tree Measurements and Sapling Data 6 Seedling 6 Seedling Data 7 Site Tree 7 Site Tree Information 8 Phase 2 Vegetation Profile (core 8 Phase 2 (P2) Vegetation Profile (core optional) optional) 9 Invasive Plants 9 Invasive Plants 10 Down Woody Materials 0.0 General Description. Paragraph 5, Defined NIMS (the National Information Management System). Also Figure 1. Figure 1 was replaced by a plot diagram including the annular ring. 0.2 Plot Integrity. Copied the following paragraph (as it appears in chapter 9) to the end of the section: “Note: Avoid becoming part of the problem! There is a risk that field crews walking into plot locations could pick up seeds along roadsides or other patches of invasive plants and spread them through the forest and on to the plot. Be aware of the vegetation you are traveling through and consider stopping and removing seeds from boots and clothing before entering uninvaded lands, particularly remote areas that are rarely visited.” 1.3 PLOT NUMBER. Changed When collected from “SAMPLE KIND=1 or SAMPLE KIND=2” to “All plots”. 1.6 NONFOREST PLOT STATUS. Changed When collected from “When PLOT STATUS = 2 and NONFOREST SAMPLING STATUS = 0 or 1” to “When PLOT STATUS = 2 and NONFOREST SAMPLING STATUS = 1”. Also changed the first sentence from “Record the code that describes the sampling status of the other-than-forest plot, i.e., PLOT STATUS = 2.” to “Record the code that describes the plot status of the nonforest plot, i.e., PLOT STATUS = 2.” 1.8 NONFOREST PLOT NONSAMPLED REASON. Changed description from “For entire plots that cannot be sampled, record one of the following reasons.” to “For entire nonforest plots that cannot be sampled, record one of the following reasons.” 1.9 SUBPLOTS EXAMINED. Changed When collected from “When PLOT STATUS = 2 or 3” to “All plots”. 1.12 FIELD GUIDE VERSION. Changed Values from “4.0” to “6.0”. 1.15 HORIZONTAL DISTANCE TO IMPROVED ROAD. Changed When collected from “All plots with either one accessible forest land condition class (PLOT STATUS = 1) or one accessible nonforest land condition class when nonforest is being sampled (PLOT STATUS = 2 and NONFOREST SAMPLING STATUS = 1 and NONFOREST PLOT STATUS =1)” to “All plots with either one 6 National Core Field Guide, Version 6.1 October, 2014 accessible forest land condition class (PLOT STATUS = 1) or one accessible nonforest land condition class when nonforest is field-measured (PLOT STATUS = 2 and NONFOREST SAMPLING STATUS = 1 and NONFOREST PLOT STATUS =1)”.
