A forest may appear rich in life and yet be highly vulnerable if key relationships between organisms are not properly understood. For instance, when a dominant species is removed, the effects may (0) RIPPLE through the entire system.

Pollinators, fungi and soil bacteria all play roles that are easy to overlook, yet they are essential to nutrient cycling and plant regeneration. If one component declines, the ecosystem may lose its capacity to recover from disturbance. In this sense, resilience is not simply a matter of size, but of how well the system can (3) .......... shocks.\n\nConservationists also warn against focusing exclusively on charismatic animals.
