[abstract] Large old trees are among the biggest
organisms on Earth. They are keystone structures in forests, woodlands,
savannas, agricultural
landscapes, and urban areas, playing unique
ecological roles not provided by younger, smaller trees. However,
populations
of large old trees are rapidly declining in many
parts of the world, with serious implications for ecosystem integrity
and
biodiversity.
