Burning Flashcards
Burning is one of many strategies employed by Indigenous peoples for ____ to _____ and _____ the landscapes within which they lived
for millennia to control and steward the landscapes
Why low intensity fires?
clear out underbrush, thin out young trees, reduce the amount of fuel accumulating on the forest floor (fuel load)
Why are high intensity fires “bad”?
A water-repellant or hydrophobic layer is sometimes formed in the soil that will decrease water infiltration and increase runoff and soil erosion
The paradigm of ‘zero fire’
fires seen as a threat to biodiversity etc.
response is to suppress fires
What are the benefits of burning? (9)
● Promotes early successional vegetation and associated animals
● Discourages pests and weed growth
● Accelerates nutrient cycling – releases nutrients in ash
● Blackened ground encourages spring growth
● Selects for annuals and perennials –> Annuals and perennials (many pre-adapted to fire) to increase the production of foods (berries, tubers, leafy greens) and medicines.
● Some plants need fire for seed dispersal and germination.
● Synchronization of fruiting
● Shifts in vegetation mosaics; creates openings in forests
● Promotes fire-tolerant, shade-intolerant taxa

patch burning
Does patch burning benefit everyone?
Potential Downsides: Fire, Forest Clearing, Soil erosion
- severe fires can result in a net loss of nitrogen in the soil system.
- can overly warm soils in the summer and this may kill plants.
- Health risks from smoke.
- Impact on fauna.
Solutions to problems w reintegration of Indigenous burning:
enabling policies that focus on legitimizing and strengthening Indigenous fire management
Community owned fire management linked to Indigenous survival strategies
Long-term approaches supporting the well-being and survival of Indigenous communities,
