Quadra Island: clam gardens and tended coastal landscapes

Reviewed community and place names are preserved where supported; no otherwise unknown ancient self-designation is invented.

The original study combines samples and changing sea level; different methods and disturbed deposits complicate construction dates. SFU's collaborative project describes intertidal terraces that expanded clam habitat, not untouched wilderness.

Intertidal cultivation and landscape context Approximately 3500 years ago–1700 CE; later disruption and restoration distinguished Radiocarbon and sea-level analysis, ecological research and Indigenous collaborative knowledge Campbell River, British Columbia, Canada (orientation only): approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, private compound or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, fishing, farming, water-rights or route boundary. The orientation may be far from the archaeological context. No access, collecting or travel permission is implied.
Aperçu

Connexions côtières, insulaires, estuariennes et fluviales

Campbell River, British Columbia, Canada is a modern orientation, not an ancient capital or boundary. House-group management and changing local practices must not become a claim that every beach had one owner or one coastal government.

Organisation politique et échelle communautaire

House-group management and changing local practices must not become a claim that every beach had one owner or one coastal government. Clam-garden dates are difficult and method-dependent; archaeological evidence does not authorize harvesting, ownership or restricted knowledge claims.

Transformation ultérieure, patrimoine vivant et réception moderne

Living communities and heritage institutions retain their own authority; this atlas cannot establish identity, ancestry, descent, recognition or membership. Laich-kwil-tach and Coast Salish community contexts are distinct; a garden wall does not identify every builder's language. Later colonial, research, reconstruction and stewardship events are dated separately from the main archaeological context.

Dating limits The original study combines samples and changing sea level; different methods and disturbed deposits complicate construction dates.

Séquence historique

Uma cronologia breve e documentada

Ces repères servent d'orientation et ne constituent pas une histoire complète.

  1. Early garden evidence

    The original study proposes this antiquity for sampled contexts with explicit dating qualifications.

    [S1]

  2. Changing shorelines and tending

    The collaborative project describes adjustment of gardens as coastal conditions changed.

    [S2]

  3. Colonial disruption

    The project relates reduced construction to multiple consequences of colonization, not cultural extinction.

    [S2]

  4. Published dating study

    Researchers evaluated multiple dating approaches and excluded samples that could not securely date garden use.

    [S1]

  5. Collaborative stewardship

    SFU reports work involving First Nations and researchers; the atlas is not a partner in that project.
