2. Indicator species An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a ecosystem, and thus may be used as a proxy to diagnose the health of an  ecosystem . Phytoremediation ( technologies that use living plants to clean up soil, air, and water contaminated with hazardous contaminants.)

3. A species having impacts on many others, often far beyond what might have been expected from a consideration of their biomass or abundance. Umbrella species

4. Don’t Harm Popular charismatic species that serve as symbols and rallying points to stimulate conservation awareness and action A species that has become a symbol and leading element of an entire conservation campaign Flagship species
