Phytoliths & Pollen Analysis
Study of the climate before modern weather tracking; involves ice cores
Paleo ecology
Dating past events by using tree rings

4 stages: natural, huntergather, agriculture, industrial
Pyric Phase Module
Indigenous peoples way of protecting the land and promoting biodiversity in landscapes
Indigenous Fire stewardship
Fire for rituals and to manage the land
Cultural burning
Study of how people interact with the environment
Ethnoecology
The views on lifestyle and information about land, world views, and relationships in the environment from indigenous peoples
Traditional ecological knowledge (TEK)
Having fire dependent and fire tolerant species which interact
Fire Adapted Ecosystem
The pattern/ cycles of fire that are influenced by humans
Anthropogenic Fire Regimes
ponderrose, jeffry pines, douglas fir
most common types of forest in CA
low severity, frequent, seeds spread in the fall and sprout after fire
Mixed Conifer forests in Sierra Nevada
large scale fires, every 80-200 years, kill 50% of trees, seeds released by the resin
lodgepole pine forests in Rocky Mountains and Yellowstone
evergreen land with shrubs (manzanita) and lilacs, high severity fires, infrequent fires BUT turns into grasslands bc these species are less resistant to fires
Cali Chaparral
keeps its leaves all year long into the next growing season
evergreen
the plant dies but comes back without replanting
perennial
non native plants changed the ecosystem, hgih severity fires
annual grasslands
precipitation, high fire ground, grasslands disappear, douglas fir encroach, soil temperature is insulated and seeds still survive
coastal praire
