What is biodiversity in woodland?

Biodiversity is a term which simply means ‘the variety of life’. The range of biodiversity in woodlands is largely determined by four factors. These are: … Structural diversity in the woodland – the number of different microhabitats available.

What is biodiversity in a forest?

Biodiversity refers to the range of life forms and species that exist within a given ecosystem. … Species exist within a particular forest ecosystem because they have adapted to the climatic, edaphic, or other conditions within that forest, and/or they depend upon other species within that ecosystem.

Do woodlands have high biodiversity?

Diversity is important in a woodland, so mature areas favour bats amongst other species and veteran trees are home to many species of invertebrate (insects, spiders, millipedes, centipedes etc), not to mention lichens and fungi. Diversity in the structure of the woodland leads to biodiversity.

How does woodland increase biodiversity?

Biodiversity. A number of studies have shown that in the UK managed woodlands increase in biodiversity value. Woodlands are not static entities that can be left without interference, they are changing environments and as trees grow larger; the nature of the habitat will change.

How do you measure the biodiversity of a woodland?

Species diversity is measured through a combination of species richness (the number of species present) and species evenness (the relative abundance of each species). Species richness and evenness can be combined into a single indicator, and in ecology the Shannon Index is commonly used.

What biodiversity means?

Biodiversity is the shortened form of two words “biological” and “diversity”. It refers to all the variety of life that can be found on Earth (plants, animals, fungi and micro-organisms) as well as to the communities that they form and the habitats in which they live.

Why is biodiversity important in a forest?

Forests and wetland ecosystems provide crucial buffers to extreme storms and flooding related to climate change. These ecosystems are complex, which means they function best, and are more resilient to the effects of climate change, when all the pieces of the ecosystem are in place — meaning the biodiversity is intact.

How do trees relate to biodiversity?

Trees help clean the air we breathe, filter the water we drink, and provide habitat to over 80% of the world’s terrestrial biodiversity. Forests provide jobs to over 1.6 billion people, absorb harmful carbon from the atmosphere, and are key ingredients in 25% of all medicines.

Why is biodiversity important?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

How does woodland clearance reduce biodiversity?

Deforestation directly reduces the number of trees and sometimes the number of different tree species. Deforestation also destroys habitats, so some species could lose their shelter and food source. This means that these species will die or be forced to migrate to another suitable area, further reducing diversity.

Why are trees important to biodiversity?

Trees provide soil and water conservation, facilitate carbon sequestration, improve biodiversity and increase the number of pollinators and natural pest predators, like birds. At least 1/3 of world’s crops depends upon pollination provided by insects and other animals.

Why is it important to maintain a diversity of trees within a woodland?

Our whole society and agricultural system relies on the biodiversity of pollinators, soil organisms, natural predators of crop pests and many more. Trees and woodland ecosystems in particular provide clean air, offer protection from flooding, and store carbon – vital if we’re to prevent catastrophic climate breakdown.

Which type of tree supports more biodiversity?

The differences can be stark and remarkable: native trees tend to harbour far more wildlife than exotic species. Indigenous oak species, for example – according to the table extracted from scientific papers by the Offwell Woodland and Wildlife Trust – harbour 284 insect species in the UK.
