What is Urban Ecology?
Notes
Social Factors
• Interactions between humans
• Interactions between humans and their environment
• Health of people
• Government support
• Economic development
• Public transportation
Biological Factors
• Biodiversity
• Health of life forms
• Disease
• Wildlife
• Vegetation -plants, trees, grass, bushes,
Physical Factors
• Location and layout• Mountains, rivers, creeks, valleys, hills,
trees• Buildings, parking lots, roads, homes, • Climate, temperature, atmosphere• Electricity• Food availability• Clean / dirty
Chemical Factors
• Quality of air, water, soil, pollution
Urban Ecology
• New branch in environmental science
• Understand the health of cities and the threats that face them
Urban Ecology
• Study of trees, rivers, wildlife, and open spaces
• City resources - water, air, soil
• Affects of pollution, overdevelopment, and over population
Why study urban ecology?
• Cities are living ecosystems
• To promote the health of people and their environment
• Help residents and policy makers make better decisions and take action
Why study urban ecology?
• Observe local birds• Clean up water• Clean up air• Clean up abandoned property
(brownfields)• Create parks and gardens • Plant trees• Social connection with environment
Urban Ecosystems
Include an interaction of biotic factors• People• Living organisms
Abiotic Factors• Water, soil, air
Man Made Factors• Buildings, roads, cars….
Connection between Humans and Ecology
Humans influence ecological factors
• plants, animals, air, and soil
Ecological factors influence human decisions
• Where to build houses, parks, highways, schools, hospitals
Puzzle
• Take out page 30 in your packet
• 6. Cities are complex urban ecosystems
• Urban ecosystems are like a puzzle
• Social, biological, physical, and chemical
• To understand how an urban ecosystem works you need to understand that the four factors have impacts on each other
