The Tundra Reference Guide
A plain, sourced guide to Arctic and alpine tundra — growing seasons, permafrost, a Rocky Mountain summer, and a NOAA note on Arctic greenness — with a comparison table that keeps National Park Service wordings labelled, and credited public-domain and CC BY photographs.
What’s inside:
- How to use this guide
- Two kinds of tundra
- The Arctic year
- Different lines on the map
- Alpine tundra, and a Rocky Mountain summer
- Low plants, and a midwinter photograph
- Permafrost, kept labelled
- A sourced comparison table
- Credits and sources
Pages: 11 (A4) / 11 (US Letter). Formats: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.
Printing: Print at 100% / actual size on A4 or US Letter. Most inside pages use light backgrounds and print well in black and white; the cover is dark, so print that in colour or skip it to save ink.
Every fact is written in our own words and checked against named sources (National Park Service tundra pages (the Arctic overview, Rocky Mountain National Park, Lake Clark, and National Natural Landmarks) and the NOAA Arctic Report Card 2022), checked 15 November 2026. The sources are listed on the credits page. Where those pages print different lines or different permafrost wordings, both are shown and labelled.
Images are public-domain or CC BY photographs, credited on the credits page, and resized with no other changes. Captions say whether a scene is Arctic or alpine, and name the park or refuge when the file does. This pack is independent and is not affiliated with, or endorsed by, the National Park Service, NOAA, or the U.S. Fish and Wildlife Service.
