Long Term Monitoring Programs

• Indicator species are sensitive to
  environmental change and if there is too much
  change (pesticides, acid rain, loss of habitat,
  and the introduction of non-native species) then
  they will not be able to survive
• Amphibians are great indicator species

• Because amphibian populations fluctuate from year
  to year, it is important to monitor populations
  over time.
