Isolation of one habitat fragment from other areas of habitat
Breaking up of one patch of habitat into several smaller patches
Decrease in the average size of each patch of habitat
Natural causes and effects
Evidence of habitat destruction through natural processes such as volcanism, fire, and climate change is found in the fossil record. For example, habitat fragmentation of tropical rainforests in Euramerica 300 million years ago led to a great loss of amphibian diversity, but simultaneously the drier climate spurred on a burst of diversity among reptiles.

Seed Dispersal and Habitat Fragmentation | HHMI BioInteractive Video
Watch researchers follow brown spider monkeys in a tropical forest of Colombia to determine which plant seeds they are dispersing. Seed dispersers are critical to the forest’s ability to grow and regenerate.
As the tropical forests of Colombia are cleared for farmland and cattle ranches, the remaining patches of forest become fewer, smaller and further apart from each other threatening the survival of the animals that live there, including brown spider monkeys. Brown spider monkeys are critical seed dispersers and as their numbers decrease the forest is less able to regenerate. Andres Link and Carolina Urbina Malo of Los Andes University in Colombia are identifying the seeds that spider monkeys disperse to better understand the monkeys’ role in the forest and to predict which plants will...

Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation. Habitat fragmentation can be caused by geological processes that slowly alter the layout of the physical environment[1] (suspected of being one of the major causes of speciation[1]), or by human activity such as land conversion, which can alter the environment much faster and causes extinctions of many species.
The term habitat fragmentation includes five discrete phenomena:
Reduction in the total area of the habitat
Decrease of the interior : edge ratio
Isolation of one habitat fragment from other areas of habitat
Breaking up of one patch of habitat into several smaller patches
Decrease in the average size of each patch of habitat
Evidence of habitat destruction through natural processes such as volcanism, fire, and climate change is found in the fossil record.[1] For example, habitat fragmentation of tropical rainforests in Euramerica 300 million years ago led to a great loss of amphibian diversity, but simultaneously the drier climate spurred on a burst of diversity among reptiles.
Habitat fragmentation is frequently caused by humans when native vegetation is cleared for human activities such as agriculture, rural development, urbanization and the creation of hydroelectric reservoirs. Habitats which were once continuous become divided into separate fragments. After intensive clearing, the separate fragments tend to be very small islands isolated from each other by cropland, pasture, pavement, or even barren land. The latter is often the result of slash and burn farming in tropical forests. In the wheat belt of central western New South Wales, Australia, 90% of the native vegetation has been cleared and over 99% of the tall grass prairie of North America has been cleared, resulting in extreme habitat fragmentation.

Human Impacts on Biodiversity | Ecology and Environment | Biology | FuseSchool
Biodiversity is the variety of life. There are thought to be 8.7 million species on planet Earth. And, as we saw in the video, "Why does biodiversity matter to me?", biodiversity is of utmost importance to humans.
The loss of one key species can have a detrimental impact on many levels; from other species of animals to plants to the physical environment.
Human activities are reducing biodiversity. Our future depends upon maintaining a good level of biodiversity, and so we need to start taking measures to try and stop the reduction.
In this video, we are going to look at how humans are negatively impacting biodiversity.
As the world population has grown from 1.5 billion in 1900 to nearly 7.5 billion people today, unsurprisingly the land use has changed.
Habitats have been destroyed in favour of agriculture, forestry, fishing, urbanisation and manufacturing. Unsurprisingly, habitat loss has greatly reduced the species richness. Habitat fragmentation has also meant that populations have been split into smaller subunits, which then, when faced with challenging circumstances, have not been able to adapt and survive.
After habitat loss, over-harvesting has had a huge effect on biodiversity. Humans historically exploit plant and animal species for short-term profit. If a resource is profitable, we develop more efficient methods of harvesting it, inevitably depleting the resources, as is currently happening with fishing and logging. The exploited species then needs protection. The difficulty is that the demand then outstrips the supply, and so the resource value rises. This increases the incentive to extract the resource and leads to the final collapse of the population, as happened with whales, elephants, spotted cats, cod, tuna and many more species.
Human activities are polluting the air and water. Toxic discharge into the water from industrial processes unsurprisingly has a negative effect on the local aquatic species by killing, weakening or affecting their ability to reproduce. Another big water pollution problem is eutrophication. Phosphorous and nitrogen in fertilisers run-off agricultural fields and pass into rivers. These surplus nutrients cause algae to bloom, which then starves other aquatic species of oxygen and light, causing them to die.
Acid rain is one consequence of humans polluting the air. This causes lakes and water bodies to become more acidic, killing off fish, molluscs, amphibians and many other species.
A huge impact humans have had on planet Earth is the introduction of alien species to habitats. In fact, it is estimated that on any given day there are 3000 species in transit aboard ocean-going vessels! Alien species can cause problems in a number of ways.
Throughout the earth’s history there have been periods of rapid climate change that have led to mass extinction events. We are currently in a period of fluctuating climate, but nearly all scientists agree that human activities, like burning fossil fuels, are speeding up global warming.
We don’t know how much climate change is going to affect biodiversity in future, but it’s predicted to be huge. Loss of sea ice and ocean acidification are already causing huge reductions in biodiversity. Climate change alters temperature and weather patterns, with changing patterns of rainfall and drought expected to have significant impacts on biodiversity.
You can search the internet to find more human-related impacts on biodiversity.

This increases the incentive to extract the resource and leads to the final collapse of the population, as happened with whales, elephants, spotted cats, cod, tuna and many more species.
Human activities are polluting the air and water. Toxic discharge into the water from industrial processes unsurprisingly has a negative effect on the local aquatic species by killing, weakening or affecting their ability to reproduce. Another big water pollution problem is eutrophication. Phosphorous and nitrogen in fertilisers run-off agricultural fields and pass into rivers. These surplus nutrients cause algae to bloom, which then starves other aquatic species of oxygen and light, causing them to die.
Acid rain is one consequence of humans polluting the air. This causes lakes and water bodies to become more acidic, killing off fish, molluscs, amphibians and many other species.
A huge impact humans have had on planet Earth is the introduction of alien species to habitats. In fact, it is estimated that on any given day there are 3000 species in transit aboard ocean-going vessels! Alien species can cause problems in a number of ways.
Throughout the earth’s history there have been periods of rapid climate change that have led to mass extinction events. We are currently in a period of fluctuating climate, but nearly all scientists agree that human activities, like burning fossil fuels, are speeding up global warming.
We don’t know how much climate change is going to affect biodiversity in future, but it’s predicted to be huge. Loss of sea ice and ocean acidification are already causing huge reductions in biodiversity. Climate change alters temperature and weather patterns, with changing patterns of rainfall and drought expected to have significant impacts on biodiversity.

Habitats provide vital resources—such as food, shelter, and mates—that support an organism’s survival. A dense, continuous forest habitat, for example, hosts a sizable and diverse wildlife population. However, natural forces and human activity can change a habitat and impact the resident organisms.
Isolation of one habitat fragment from other areas of habitat
Breaking up of one patch of habitat into several smaller patches
Decrease in the average size of each patch of habitat
Natural causes and effects
Evidence of habitat destruction through natural processes such as volcanism, fire, and climate change is found in the fossil record. For example, habitat fragmentation of tropical rainforests in Euramerica 300 million years ago led to a great loss of amphibian diversity, but simultaneously the drier climate spurred on a burst of diversity among reptiles.
The conversion of forests to farmland during colonial times set the stage for prime cottontail habitat ... In addition, increased development has fragmented the remaining suitable habitat and brought with it an increase in predators like coyote and fox.
... has disrupted their natural habitat into isolated fragments — each piece smaller and more inhabitable than the last — preventing them from migrating freely within the river to find food and shelter.”.

But over the years, these corridors became fragmented, and their habitat was damaged ... tigers, along with other wildlife, are being forced to come out of their habitats and find new places of refuge.
This can be attributed to habitat fragmentation, warming water temperatures, competition from non-native trout species and more, according to the DEP. Brook trout require cold, high-quality habitats.
While their conservation status is presently in the "low concern" range, it's a fragile status as the organization notes that their numbers have significantly declined due to the loss or fragmenting of habitat.
