The author identified the federal land networks and their significance to YEA; Claude contributed to organizing the import strategy and estimating scope.

Abstract

With YEA's curated places catalog reaching 1,142 sites across six continents and 23 organizations, several major US federal land designation networks have been identified as high-priority import candidates. Each represents a formally designated, geographically precise, ecologically significant collection of places with federal registry data including coordinates, boundaries, and management metadata. This note captures the import roadmap and prioritization.

1. Candidate Networks

1.1 USFS Research Natural Areas (RNA)

Approximately 450 permanently protected reference areas designated by the US Forest Service and Bureau of Land Management. RNAs are established to maintain natural ecosystem processes for research and education with minimal human disturbance. Many have decades of baseline ecological data. These are among the most scientifically rigorous land designations in the federal system and align precisely with YEA's mission.

• Managing agencies: USDA Forest Service, BLM
• Estimated count: ~450
• Data source: USFS RNA database, Federal Register designations
• Priority: High — direct alignment with YEA's ecological research focus
• YEA place type: Research Natural Area (id=8, already exists)

1.2 USFWS National Wildlife Refuges (NWR)

Over 560 refuges in the National Wildlife Refuge System, managed by the US Fish and Wildlife Service. Many have visitor centers, interpretive trails, research programs, and long-term wildlife monitoring. Refuges range from urban sites like Tualatin River NWR to vast wilderness areas like Arctic NWR.

• Managing agency: US Fish and Wildlife Service
• Estimated count: ~560
• Data source: USFWS Refuge Locator, FWS Cadastral database
• Priority: High — significant facilities, public access, education programs
• YEA place type: National Wildlife Refuge (id=11, already exists)

1.3 BLM Areas of Critical Environmental Concern (ACEC)

Hundreds of BLM-designated areas with significant ecological, cultural, historic, or scenic values requiring special management. ACECs protect sensitive species habitat, rare plant communities, and culturally important landscapes on public lands.

• Managing agency: Bureau of Land Management
• Estimated count: Several hundred (exact count TBD)
• Data source: BLM ACEC database, BLM GeoCommunicator
• Priority: Medium — many are remote with minimal facilities
• YEA place type: Area of Critical Environmental Concern (new, to be created)

1.4 NPS Units with Research Programs

National Park Service units with active field research stations, long-term monitoring programs, or Inventory & Monitoring networks. Not all 400+ NPS units qualify — the subset with dedicated research infrastructure is the target.

• Managing agency: National Park Service
• Estimated count: ~30-50 with active research stations
• Data source: NPS I&M Network, NPS Research Learning Centers
• Priority: Medium — selective import, many parks already covered by LTER/NEON
• YEA place type: National Park (id=9, already exists)

2. Import Strategy

2.1 Pipeline

Each network follows the established two-phase pattern: scrape structured data from federal registries, then import into yea_places with organization linkage and duplicate checking against all existing records.

2.2 Enrichment

All imports receive Tier 1 enrichment via the Ollama local pipeline on Data (gpt-oss:20b, zero API cost). High-priority sites can be selectively upgraded to Tier 2 (Haiku) or Tier 3 (Sonnet) enrichment.

2.3 Deduplication

Federal designations overlap. An RNA may sit within an NWR. A LTER site may encompass an ACEC. Cross-referencing against existing records by proximity and name matching is essential, with the option to link multiple designations to a single place rather than creating duplicates.

3. Task List

Phase 1: Research Natural Areas

• [ ] Locate USFS RNA registry with coordinates and metadata
• [ ] Build scraper for RNA dataset
• [ ] Cross-reference against existing yea_places (especially LTER, NEON sites)
• [ ] Import with organization: "USDA Forest Service"
• [ ] Enrich via Ollama batch pipeline
• [ ] Verify coordinates for sample subset

Phase 2: National Wildlife Refuges

• [ ] Access USFWS Refuge Locator API or cadastral dataset
• [ ] Filter to refuges with visitor facilities, research programs, or education centers
• [ ] Build scraper and import script
• [ ] Import with organization: "US Fish and Wildlife Service"
• [ ] Enrich via Ollama batch pipeline
• [ ] Tag with existing place type: National Wildlife Refuge

Phase 3: Areas of Critical Environmental Concern

• [ ] Locate BLM ACEC dataset with coordinates
• [ ] Create new place type: Area of Critical Environmental Concern
• [ ] Import with organization: "Bureau of Land Management"
• [ ] Enrich via Ollama batch pipeline

Phase 4: NPS Research Stations

• [ ] Identify NPS units with active research programs
• [ ] Cross-reference against existing LTER/NEON sites to avoid duplication
• [ ] Selective import of research-active parks not already in catalog
• [ ] Import with organization: "National Park Service"

Supporting Tasks

• [ ] Create federal agency organizations in yea_organizations: USDA Forest Service, US Fish and Wildlife Service, Bureau of Land Management, National Park Service
• [ ] Normalize country field: consolidate "USA" and "United States" entries
• [ ] Normalize continent-as-country entries from ILTER import (Europe, Asia, Africa)
• [ ] Review and refine place type taxonomy after enrichment provides site descriptions

4. Projected Catalog Growth

Estimated catalog size after federal lands import: approximately 2,000-2,200 curated places.
