Key Takeaways

• Urban areas are spreading quickly, replacing diverse natural habitats with buildings and roads, which leads to the loss of animal and plant species.
• Habitat destruction due to urban expansion creates isolated patches of nature that disrupt ecosystems and reduce genetic diversity among wildlife populations.
• New invasive species often come into cities through trade and travel, outcompeting local plants and animals for resources, which can cause native species to die off.
• CREAF’s research shows that rapid city growth destroys critical habitats for wildlife, illustrating the need for conservation efforts in places where humans live and work.
• A key part of protecting city biodiversity is planning urban environments carefully to include green spaces like parks that link together so animals can move around safely.

Defining Urbanisation and Biodiversity

Urbanisation refers to the process of urban development and expansion, leading to the transformation of natural landscapes into built environments. Biodiversity, on the other hand, encompasses the variety and variability of life forms within a given area, including species diversity, genetic diversity, and ecosystem diversity.

Definition of Urbanisation

Urbanisation marks the increase in the proportion of people living in towns and cities. It involves the transformation of natural lands into built environments, such as houses, roads, and commercial areas.

This change typically comes hand in hand with economic growth as rural inhabitants move towards urban centres seeking better job opportunities. The process can lead to urban sprawl where cities expand uncontrollably.

As a result of this expansion, ecosystems face significant stress, which often paves the way for biodiversity decline and habitat loss. Urban land expansion disrupts ecological processes by replacing varied habitats with anthropogenic structures.

Recognising these changes is key to understanding how urban development poses challenges to wildlife conservation efforts.

Definition of Biodiversity

Urbanisation leads to habitat loss, which in turn impacts biodiversity. Biodiversity refers to the variety and variability of life on Earth, encompassing different species, genetic diversity within each species, and the various ecosystems they form.

It includes not only a vast array of plants and animals but also their interactions with each other and their environments. This richness ensures ecosystem stability, resilience, and productivity.

Biodiversity also plays a crucial role in providing essential ecosystem services such as pollination of crops by insects, regulation of climate through carbon sequestration in forests, nutrient cycling in soils by microorganisms, and natural pest control provided by predators.

The Effects of Urbanisation on Biodiversity

Urbanisation has led to habitat loss and fragmentation of natural habitats, making it difficult for many species to survive. Invasive species are also introduced, impacting the native flora and fauna.

These effects have resulted in local extinction and a reduction in overall biodiversity in urban areas.

Habitat loss

As urban areas expand, natural habitats are lost to make way for infrastructure and human settlements. This destruction leads to the displacement and local extinction of many plant and animal species.

As a result, the overall species richness in these areas decreases, contributing to global biodiversity loss. Once abundant ecosystems become fragmented, leaving remaining natural spaces smaller and isolated.

This fragmentation disrupts ecological processes and further accelerates environmental degradation.

Efforts are needed to address habitat loss due to urbanisation through innovative conservation strategies such as green building initiatives, sustainable urban planning, and the establishment of urban wildlife corridors.

Fragmentation of natural habitats

Urbanisation leads to the fragmentation of natural habitats, disrupting ecosystems and affecting biodiversity. This process occurs when urban development causes landscapes to be divided into smaller, isolated patches, altering the ability of species to move and access resources.

As a result, this can lead to a decline in species diversity and an increase in local extinctions.

Fragmentation also affects the functioning of ecosystems by reducing gene flow between populations and altering interactions within food webs. This ecological disruption further threatens wildlife populations and can ultimately lead to ecosystem degradation.

Introduction of invasive species

The introduction of invasive species into urban areas disrupts the delicate balance of native ecosystems. These non-native plants and animals outcompete local species for resources, leading to a decline in biodiversity.

Invasive species are often introduced unintentionally through human activities such as trade and travel, and once established, they can have devastating effects on local flora and fauna.

This threat poses major challenges to conservation efforts in urban environments.

Invasive species pose a significant risk to the stability of urban ecosystems by altering habitats, influencing food webs, and even driving native species towards extinction. Controlling their spread requires proactive management strategies that aim to prevent new introductions while also mitigating the impact of existing invasive populations.
