| Season | Location | Primary Activities | Key Resources |
| Spring (Apr–Jun) | River valleys, falls | Anadromous fishing, planting, maple sugaring | Salmon, shad, alewives, eels; corn/beans/squash; maple sap |
| Summer (Jun–Aug) | River villages, coast | Gardening, shellfishing, gathering, trade | Corn, beans, squash, sunflower; clams, oysters; berries, nuts |
| Fall (Sep–Nov) | Inland forests, mast areas | Harvest, nutting, hunting, trapping | Acorns, chestnuts, hickory; deer, bear, turkey, beaver |
| Winter (Dec–Mar) | Protected valleys, caves | Hunting, ice fishing, stored food, craft production | Deer, moose, caribou; ice fishing; cached corn, dried meat/fish |
Subsistence Pillars
Agriculture: The "Three Sisters" Polyculture
- Corn (wampum): Northern flint varieties (8-row, 90-day maturity) adapted to short season
- Beans (skamon): Climbing varieties using corn stalks; nitrogen fixation
- Squash (wassawa): Ground cover suppressing weeds, retaining moisture
- Supplements: Sunflower (oil, dye), Jerusalem artichoke, groundnut (Apios)
- Fields: Cleared by girdling/burning; fertilized with fish (menhaden, herring); rotated/fallowed
Hunting and Trapping
- Big game: White-tailed deer (primary), moose, black bear, caribou (north), elk (pre-contact)
- Small game: Beaver (critical for fur trade later), muskrat, otter, rabbit, squirrel
- Techniques: Bow (self bow, sinew-backed), spear, atlatl (early), snares, deadfalls, drives, fire surrounds
- Utilization: Meat, fat, bone tools, sinew, hide (clothing, shelter), antler, hoof
Fishing: Riverine and Coastal Abundance
- Anadromous runs: Atlantic salmon, American shad, alewife, blueback herring, sea lamprey, American eel — massive seasonal protein pulses
- Resident species: Brook trout, lake trout, whitefish, perch, pickerel
- Techniques: Weirs (stone/wood), traps, nets (gill, dip, seine), spears, hooks (bone, copper), poisoning (walnut hulls in pools)
- Preservation: Smoking, drying, fermentation
Gathering: Botanical Knowledge Systems
- Nuts/mast: Acorns (leached), chestnuts, butternuts, hickories, beechnuts — caloric staple
- Berries/fruits: Strawberry, blueberry, raspberry, blackberry, elderberry, grape, cranberry
- Roots/tubers: Groundnut, Jerusalem artichoke, cattail, arrowhead
- Medicinals: >200 species documented; wintergreen, goldthread, bloodroot, slippery elm, etc.
- Materials: Birchbark (containers, canoes), basswood fiber (cordage), spruce root, ash (baskets)
Social and Technological Adaptations
- Mobility: Seasonal camps (wigwams/wigwôm — sapling frame + bark/mats); winter villages (longhouses/dagwam)
- Transport: Birchbark canoes (river/coastal), snowshoes (agimak), toboggans
- Storage: Underground cache pits (lined with bark/grass), raised platforms, ceramic vessels
- Trade networks: Lithics (Mt. Jasper rhyolite, Pennsylvania jasper), copper (Lake Superior), shells (coast), ideas
- Fire ecology: Controlled burns for blueberry, oak mast, browse, travel corridors
Spiritual-Ecological Framework
Subsistence was inseparable from relational ontology: animals, plants, places as persons with whom humans negotiate. Rituals—first fish ceremony, green corn dance, bear ceremony, maple thanksgiving—maintained reciprocity. Gici Niwaskw (Great Spirit) and Gluskabe (culture hero) narratives encoded ecological wisdom.
Contact-Era Resilience
Despite epidemics (1616–19, 1633–34: 75–90% mortality), land loss, and warfare, Abenaki peoples persisted through: strategic alliances (French, then British), refugee absorption, mission village adaptation (Odanak, Bécancour), and continued subsistence practice. Today, Cowasuck, Elnu, Koasek, Missisquoi, Nulhegan bands maintain cultural continuity in NH/VT/ME/QC.
New Hampshire's Indigenous survival was not primitive foraging but engineered abundance—a millennia-refined system turning seasonal variability into reliable prosperity.
