What is forest diversity?

Forest biological diversity is a broad term that refers to all life forms found within forested areas and the ecological roles they perform. Forest biological diversity can be considered at different levels, including the ecosystem, landscapes, species, populations and genetics.

Why do we need to know about forest genetic?

Tree genetic diversity is vital in landscape restoration efforts. Tree populations need genetic variation for survival, good growth and viability in the long term. It enhances resistance to acute and chronic stressors, such as pests and diseases, and the effects of global warming.

What is an example of genetic diversity?

Different plant breeds are crossbred to get the desired trait in a particular plant. Humans have created dog breeds by selective breeding. Coyotes are naturally evolved generalist species adaptive to an array of environments.

Do trees have genetic diversity?

Furthermore, different plant species contain varying amounts of genetic variation. Trees, for example, have been found to contain significantly more variation than herbaceous plants (Hamrick 1979, Hamrick and others 1979).

Why is forest diversity important?

Forests are critical habitats for biodiversity and they are also essential for the provision of a wide range of ecosystem services that are important to human well-being. There is increasing evidence that biodiversity contributes to forest ecosystem functioning and the provision of ecosystem services.

What does a forest geneticist do?

Understand the genetic control of important traits at the molecular, organ, tree and population levels. Develop resistance to pests and diseases of forest trees using genetics and genomics. Conserve genetic diversity of important commercial and native tree species.

What is the best example of genetic diversity?

What is the best example of genetic diversity? Different breeds of dogs as a result of selective breeding is one of the best example of genetic diversity. There are more than 50,000 varieties of rice and more than a thousand varieties of mangoes found in India.

How do you explain genetic diversity?

Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits. Genetic diversity is critical for a population to adapt to changing environments.

How can we improve forest diversity?

Strategies for Conserving Forest Biodiversity

  1. Protect habitat.
  2. Reduce fragmentation.
  3. Control introduced animals or plants.
  4. Reduce pollution.
  5. Using sustainable harvesting practices.
  6. Economic.
  7. Environmental.
  8. Personal values.

Why are forest and tree genetic diversity matters?

Forest foods – wild fruits, nuts, vegetables, mushrooms and animal products – contribute to global food security. They help maintain household nutrition and provide a lifeline to rural populations especially between harvests or during extreme weather events like extended droughts when food can be scarce. Yet many of these trees are under threat.

How does species diversity affect a forest ecosystem?

Species diversity in a forest ecosystem depends on the genetic diversity of key tree species. For example, as genetic diversity of the main tree species is lost, other species, like insects and fungi, that are specifically associated with certain trees may disappear too, leaving the whole forest ecosystem biologically impoverished. 3.

Where are genetic resources found in a forest?

Genetic resources of several important timber, fruit and other non-timber tree species are conserved ex situ in genebanks or maintained in field collections. Nevertheless, in situ conservation in forests and on farms is in the case of most tree species the most important measure to protect their genetic resources.

When was the first state of Forest Genetic Resources published?

In 2014, the Food and Agriculture Organization of the United Nations published the first State of the World’s Forest Genetic Resources.
