EEB 484 Final

Side ASide B
Pest resurgence occurs if the targeted pest species bounces back to damaging levels after pesticide application.
Secondary pest outbreak pesticides can also cause this if another species other than the targeted pest become damaging.
Agroforestry Silvopastoral farming, mixing agriculture, forestry and grazing.
Organic certification vary, but no synthetic fertilizers or pesticides are to be used for several consecutive growing seasons.
LEI (Low external input) combines the best of both wildlife-friendly and land-sparing practices. (minimized pesticides)
IPM(integrated pest management) a suite of techniques that helps reduce the use of synthetic pesticides-- last resort.
CCD all adult honey bees suddenly disappear from a hive despite the continued presence of a queen bee. (neonicotinoids)
GE Genetically-engineered crops.
leaching (with reference to a soluble chemical or mineral) drain away from soil, ash, or similar material by the action of percolating liquid, especially rainwater.
eutrophication excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.
What are the negative effects of roads built for logging (even if it's sustainable logging)? Kill animals ; Create edge; Block dispersal; Provide access to nonnative species; Increase forest fire ignition; Cause erosion; Alter hydrology.
Alternative building materials Bamboo grown on poor soils, harvested every few years; Recycled plastics and wood fiber
Alternative fuel sources solar power-- cookers, fuel efficient stoves; side benefit: lead to improved human health.
What does unsustainable forestry look like? Large clear-cuts; Soil compaction/ erosion; Replanting with one species, same age
What does sustainable forestry look like? Minimal road building; Small clear-cuts; Selective harvest; Replanting to protect soils; Avoidance of steep slopes, riparian areas; Consideration of key nesting sites.
What are the 3 downsides to the Green Revolution? 1. eutrophication; 2. global warming; 3. toxic pesticides
What do we need to know about honeybees (3 things)? Responsible for pollinating 70% of our crops; Neonicotinoids cause neuro-degeneration in bees (developed in 1990s); Colony collapse disorder in 2000s.
Climate change will lengthen the fire season. What will the future climate be like? Longer, hotter summers; More drought; El Nino more frequent and more intense = more tropical droughts = more dead trees = more fuel = more fire = more CO2 = more climate change.
Land-sparing strategy characteristics (3 things)? 1. Use less land 2. more intense land use w/ more potential toxins 3. Highly industrialized monocultures yielding the largest possible amounts of food per unit area.
Land-sharing characteristics (4 things)? 1. Coexist with biodiversity 2. Small ag. fields interspersed w/ patches of wildlife habitat 3. Pests controlled by natural predators 4. Crops cover more land area
What's the most common pollutant in saltwater? Nitrogen
What's the most common pollutant in freshwater? Phosphorus
Wildlife-friendly strategy Envisions small agricultural fields interspersed with patches of habitat and corridors of native vegetation and natural predators rather than pesticides.
___, ___, ____, or _____ (4 things) requires less land and water and entails fewer greenhouse gas emissions and less nitrogen pollution than obtaining the same amount of protein from ____. Dairy, poultry, pork or eggs; BEEF.
Strategies for the future of forests: Alternative resources; Sustainable forestry; Economic instruments; Local involvement.
