Document Summary
Recycling: saves 45-70% of the energy, reduces air pollution by 95, conserves water and landfill space. Afpa 56% recovery in 2007, 62% by 2009. Problems: program development; <20% office paper recycled, tax subsidies and incentives new paper, emphasis on white paper chlorine pollution from cleaning recycled paper moving to. Ecf(elemental chlorine free) and tcf(totally chlorine free) methods: fluctuating prices and lack of demand. Recycled paper required for federal agencies, contractors > ,000. Important niche characteristics: cover habitat composition and complexity: critical for determining effects of habitat alteration, alterations in foraging, reproduction, mortality. Reproductive habitat: availability of nesting and den habitat. Population dynamics (life history strategy: natality - # of offsring / 1000 females / year, population growth potential, clue to mortality and lifespan. Natality can be closely tied population size and female nutrition. Inversity, density dependent production and survival of young.
