Relationship between vital attributes of Ktunaxa plants and natural disturbance regimes in Southeastern British Columbia Mah, Shirley
Abstract
The purpose of the study was to examine the relationship between plant resources of the Ktunaxa people and the natural disturbance regimes in southeastern British Columbia and how reduced fire frequency may have affected the plant resources. The main objectives were to determine the vital attributes or fire survival strategy for each Ktunaxa plant; validate Rowe's hypothesis on the relationships between different species groups (set of vital attributes) and fire cycle length for southeastern British Columbia; and predict which Ktunaxa plants would most likely be affected by reduced fire frequency. The proportions of species groups, based on the Ktunaxa plants and their assigned vital attributes, were determined for 13 Biogeoclimatic (BEC) sub zone/variants, ranging from low elevation ponderosa pine to subalpine ecosystems. I used a one-way nested ANOVA to test the relationships between species groups and fire cycle length. The data for southeastern British Columbia tended to be consistent with Rowe's hypothesis. Examples are presented of Ktunaxa plants most likely to be affected by reduced frequency of fire: plants that can resprout from underground parts; plants that produce wind-carried seed; and shade intolerant plants that store seed in the soil.

The purpose of the study was to examine the relationship between plant
resources of the Ktunaxa people and the natural disturbance regimes in
southeastern British Columbia and how reduced fire frequency may have affected
the plant resources. The main objectives were to determine the vital attributes or
fire survival strategy for each Ktunaxa plant; validate Rowe's hypothesis on the
relationships between different species groups (set of vital attributes) and fire cycle
length for southeastern British Columbia; and predict which Ktunaxa plants would
most likely be affected by reduced fire frequency. The proportions of species groups,
based on the Ktunaxa plants and their assigned vital attributes, were determined
for 13 Biogeoclimatic (BEC) sub zone/variants, ranging from low elevation ponderosa
pine to subalpine ecosystems. I used a one-way nested ANOVA to test the
relationships between species groups and fire cycle length. The data for
southeastern British Columbia tended to be consistent with Rowe's hypothesis.
Examples are presented of Ktunaxa plants most likely to be affected by reduced
frequency of fire: plants that can resprout from underground parts; plants that
produce wind-carried seed; and shade intolerant plants that store seed in the soil.
