• Vertical zonation creates distinct ecological communities at different elevations
• Temperature decreases by approximately 6.5°C per 1000 meters of elevation gain
• Precipitation patterns vary with altitude, often increasing up to a certain point before decreasing
• Atmospheric pressure decreases with elevation, affecting plant and animal adaptations

Biodiversity hotspots

• Mountains harbor high species diversity due to varied microclimates and isolation
• Endemism rates increase with elevation, resulting in unique species found nowhere else
• Serve as refugia for species during climate fluctuations (glacial periods)
• Act as corridors for species migration and gene flow between different regions

Fragile and sensitive environments

• Thin soils and steep slopes make mountains vulnerable to erosion and landslides
• Limited growing seasons at high altitudes slow ecosystem recovery after disturbances
• Sensitive to climate change impacts, with species forced to migrate upslope or face extinction
• Keystone species in mountain ecosystems often have narrow environmental tolerances

Indigenous peoples in mountains

• Mountain regions have been home to diverse Indigenous communities for millennia
• These communities have developed unique cultural practices and knowledge systems adapted to mountain environments
• Understanding Indigenous perspectives on mountains enriches our comprehension of environmental change in the North American West

Traditional ecological knowledge

• Encompasses multi-generational observations of local ecosystems and climate patterns
• Includes knowledge of plant and animal behaviors, seasonal changes, and weather forecasting
• Often encoded in stories, songs, and ceremonies passed down through oral traditions
• Provides valuable insights for modern conservation and climate change adaptation strategies

Sustainable resource management

• Rotational grazing practices to maintain alpine meadows and prevent overgrazing

Environmental changes in mountains

• Mountain ecosystems in the North American West are experiencing rapid environmental changes
• These changes have significant impacts on both ecological systems and Indigenous communities
• Understanding these changes provides context for Indigenous adaptation strategies and conservation efforts

Climate change impacts

• Warming temperatures lead to shifts in species distributions and phenology
• Altered precipitation patterns affect water availability and ecosystem functions
• Increased frequency and intensity of extreme weather events (droughts, storms)
• Changes in snow cover and timing of snowmelt disrupt hydrological cycles

Glacial retreat

• Accelerated melting of mountain glaciers due to rising temperatures
• Loss of critical water storage systems that regulate streamflow throughout the year
• Exposure of unstable terrain as glaciers recede, increasing risk of landslides
• Alterations to local microclimates and habitats dependent on glacial environments

Shifts in vegetation zones

• Treeline advancing to higher elevations as temperatures warm
• Alpine species facing "summit trap" with nowhere to migrate as their habitat shrinks
• Changes in plant community composition affecting wildlife and ecosystem services
• Increased risk of invasive species establishing in newly suitable habitats

Mountain ecosystem services

• Mountain ecosystems provide crucial services that benefit both local communities and broader regions
• Indigenous peoples have long recognized and sustainably managed these ecosystem services
• Understanding these services highlights the importance of mountain conservation in the North American West

Water sources and watersheds

• Mountains act as "water towers," storing and releasing water for downstream areas
• Snowpack and glaciers provide critical water supplies during dry seasons
• High-elevation forests and wetlands filter and regulate water flow
• Indigenous water management practices often align with watershed protection goals

Carbon sequestration

• Mountain forests and soils store significant amounts of carbon
• Alpine and subalpine ecosystems have high carbon storage potential per unit area
• Peatlands in mountain regions serve as long-term carbon sinks
• Indigenous forest management practices can enhance carbon sequestration

Biodiversity conservation

• Mountains support unique species assemblages and genetic diversity
• Act as refugia for species during climate change and habitat loss in lowland areas
• Provide critical habitat for wide-ranging species (migratory birds, large mammals)
• Indigenous protected areas often encompass important biodiversity hotspots

Threats to mountain ecosystems
