1

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

Data

2

How can data be collected?

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

3

What does systematic conservation planning typically involve?

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

4

What part of the conservation process is crucial?

You need to evaluate how effective your action of conservation was

5

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

6

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

Satellites monitoring earth

7

Give the drivers for deforestation in SE Asia

Timber production and oil palm conversion

8

Give the drivers of deforestation in South America

Clearing for cattle growth on pastures and soybean production

9

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.

10

Name the biodiversity hotspot in Tanzania

The eastern arc mountains

11

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

12

What are the categories of threat?

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

13

What are the three population size trends?

Fluctuating
Decreasing
Decreasing and fluctuating

14

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

15

What is the conservation approach?

Identify and implement solutions to ensure persistence

16

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

17

What is fragmentation?

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

18

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

19

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

20

Where is there geographical bias?

Towards well-studied North America, Western Europe and Australia

21

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

Amphibians and reptiles

22

What are the 4 essential biodiversity variables?

1. Abundance’s and distributions of species

2. Species traits

3. Ecosystem structure

4. Community composition
