Data And Indicators Flashcards
What does evidence come in the form of for conservation science?
Data
How can data be collected?
Through surveys, e.g number of species present, human well being indicators etc.
What does systematic conservation planning typically involve?
It identifies and implements solutions and monitors their effectiveness against set targets
What part of the conservation process is crucial?
You need to evaluate how effective your action of conservation was
What is conservation effect defined as?
Reduction of threats to the conservation target and/or an improvement in its responses to those threats through implementation of actions
What can give an accurate picture of how much tropical rainforest is being lost each year?
Satellites monitoring earth
Give the drivers for deforestation in SE Asia
Timber production and oil palm conversion
Give the drivers of deforestation in South America
Clearing for cattle growth on pastures and soybean production
What are the drivers for deforestation in Africa?
Small scale clearing for timber, charcoal and farming
This is now changing to large scale industrial clearing for oil palm etc.
Name the biodiversity hotspot in Tanzania
The eastern arc mountains
What is the most successful small scale local activity to reduce biodiversity loss in the eastern arc mountains?
Tree planting- because it gave the people education and awareness
What are the categories of threat?
Extinct Extinct in the wild Critically endangered Endangered Vulnerable to extinction Near threatened Least concern
What are the three population size trends?
Fluctuating
Decreasing
Decreasing and fluctuating
Give the conservation objective that is set out before the approach:
You need to define the current state of the population, predict its future and identify any threats to its persistence
What is the conservation approach?
Identify and implement solutions to ensure persistence
What is the objective of a population viability analysis?
To estimate the probability that a population of a species, or a collection of populations, will persist for some particular time in a particular environment
What is fragmentation?
Where a habitat is increasingly being split up into smaller, more isolated areas
What is the extinction vortex?
Reinforcement among biotic and abiotic processes driving the population size to extinction- so the smaller the population size gets, the quicker the time elapses to extinction
What is dark diversity? And in conservation do you focus on low or high dark diversity?
A set of species that are absent from a site but that could disperse to and establish there
Low dark diversity- focus on sites that are quite complete
Where is there geographical bias?
Towards well-studied North America, Western Europe and Australia
What groups have not been assessed for the IUCN red list?
Amphibians and reptiles
What are the 4 essential biodiversity variables?
- Abundance’s and distributions of species
- Species traits
- Ecosystem structure
- Community composition
