Attachment 4 - Exhibit B - Public Plot List Wrangell-Ketchikan for Contract 2026.xlsx

This is a public plot list spreadsheet for Forest Inventory and Analysis (FIA) fixed radius sample plots in the Wrangell-Ketchikan area of Alaska. The file contains 50 plot locations with associated data including plot numbers, geographic coordinates (latitude/longitude), inventory years, ownership codes, previous measurement years, condition counts, forest types, slope classifications, stand size classes, access methods, and detailed review notes for each plot. The plots span two county codes (130 and 280) with inventory year 2024 and 2023, primarily owned under code 11 (National Forest). Access methods vary by plot location, with helicopter access being the predominant method, supplemented by skiff or road access for certain plots. Most plots include notes on terrain difficulty, vegetation characteristics, hazards, and specific considerations such as cedar decline, coarse woody debris (CWD), regeneration density, and water features.

The plot review notes provide field-level details essential for conducting remeasurement and installation work under Solicitation 1240BG26Q0003. Notable observations include hiking distances and elevation changes required to reach plots, hazardous conditions such as steep slopes and cliffs, accessibility challenges including snowpack variability and avalanche zones, and special sampling considerations like cover checks and multi-subplot configurations. Several plots have missing documentation or have not been visited in the annual inventory cycle. This attachment serves as the reference inventory for contractors bidding on the Forest Service contract to locate, remeasure, and install FIA plots while providing digital data delivery in accordance with the Alaska Annual Inventory Field Instructions.
