Habitat restoration and rewilding Flashcards
Why is habitat creation and restoration sometimes more valuable than conservation of a species
- we don’t have to manage the species as much
- increase biodiversity
What habitats have been created as a result of human activities
- hay meadows
- saltmarsh
- wetlands
Why do most semi-natural habitats in the uk require management in order to maintain their features and ecosystems
- there is a fear that they can be removed and become extinct
What things should be considered when planning and designing a new nature reserve
- make sure the whole area is protected
- having corridors
- having diverse habitats
What are the abiotic features of a habitat
- temperature
- water availability
- ph
- light availability
- wind velocity
- salinity
- mineral availability
- soil type
- dissolved oxygen
How is temperature manipulated or managed
- increase - remove vegetation
- decrease - adding large bodies of water
How is water availability manipulated or managed
- increase - plant more vegetation
- decrease - drain the area
How is ph manipulated or managed
- increase - acidic
- decrease - alkaline - introduce limestone
How is light availability manipulated or managed
- increase - clear trees
- decrease - plant trees
How is wind velocity manipulated or managed
- increase - remove some vegetation
- decrease - plant thick vegetation
How is salinity manipulated or managed
- plant species that are adapted to that area
How is mineral availability manipulated or managed
- introduce different rock types
How is soil type manipulated or managed
- sandy soil - introduce clay
- clay soil - introduce more sand
How is dissolved oxygen maintained or managed
- bubble oxygen through a tube
- introduce aquatic plants and species
What are the biotic features of a habitat
- food availability
- biodiversity
- presence of pathogens
- presence of competitors
- presence of seed disburses
- presence of pollinators
- presence of predators
