Data And Indicators

Question 1

What does evidence come in the form of for conservation science?

Answer 1

Data

Question 2

How can data be collected?

Answer 2

Through surveys, e.g number of species present, human well being indicators etc.

Question 3

What does systematic conservation planning typically involve?

Answer 3

It identifies and implements solutions and monitors their effectiveness against set targets

Question 4

What part of the conservation process is crucial?

Answer 4

You need to evaluate how effective your action of conservation was

Question 5

What is conservation effect defined as?

Answer 5

Reduction of threats to the conservation target and/or an improvement in its responses to those threats through implementation of actions

Question 6

What can give an accurate picture of how much tropical rainforest is being lost each year?

Answer 6

Satellites monitoring earth

Question 7

Give the drivers for deforestation in SE Asia

Answer 7

Timber production and oil palm conversion

Question 8

Give the drivers of deforestation in South America

Answer 8

Clearing for cattle growth on pastures and soybean production

Question 9

What are the drivers for deforestation in Africa?

Answer 9

Small scale clearing for timber, charcoal and farming

This is now changing to large scale industrial clearing for oil palm etc.

Question 10

Name the biodiversity hotspot in Tanzania

Answer 10

The eastern arc mountains

Question 11

What is the most successful small scale local activity to reduce biodiversity loss in the eastern arc mountains?

Answer 11

Tree planting- because it gave the people education and awareness

Question 12

What are the categories of threat?

Answer 12

Extinct 
Extinct in the wild 
Critically endangered 
Endangered 
Vulnerable to extinction 
Near threatened 
Least concern

Question 13

What are the three population size trends?

Answer 13

Fluctuating
Decreasing
Decreasing and fluctuating

Question 14

Give the conservation objective that is set out before the approach:

Answer 14

You need to define the current state of the population, predict its future and identify any threats to its persistence

Question 15

What is the conservation approach?

Answer 15

Identify and implement solutions to ensure persistence

Question 16

What is the objective of a population viability analysis?

Answer 16

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

Question 17

What is fragmentation?

Answer 17

Where a habitat is increasingly being split up into smaller, more isolated areas

Question 18

What is the extinction vortex?

Answer 18

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

Question 19

What is dark diversity? And in conservation do you focus on low or high dark diversity?

Answer 19

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

Question 20

Where is there geographical bias?

Answer 20

Towards well-studied North America, Western Europe and Australia

Question 21

What groups have not been assessed for the IUCN red list?

Answer 21

Amphibians and reptiles

Question 22

What are the 4 essential biodiversity variables?

Answer 22

1. Abundance’s and distributions of species
2. Species traits
3. Ecosystem structure
4. Community composition
