Indicator 1.08: Population Levels of Selected Representative Forest-Associated Species to Describe Genetic Diversity, 2017
Some forest species support or rely heavily on particular forest structures, patterns, associations, and processes and can therefore be used to describe the status of genetic diversity in forests. This indicator report, tiered to the 2030 National Report on Sustainable Forests, provides information on the population status of selected forest-associated species that reflect the genetic diversity present in forest ecosystems.
