1

What is ex situ conservation

The removal of animals from their natural habitat into captivity for their long term conservation, such as to breed for reintroduction or to maintain a genetic stock

2

What is in situ conservation

The actions taken to preserve a species in its natural habitat

3

Examples of ex situ conservation of flora

Botanic gardens
Seed banks (domestic plant varieties and wild plants).
Preservation of plant tissue (cryopreserved)

4

Example of seed bank

Millennium seed bank partnership.
Kew botanic Gardens in London.

5

What does the millennium seed bank partnership do

Store seeds of all uks native plant species hoping to store 25% of the worlds plants by 2020.

6

What is the priority setting in the millennium seed bank partnership

Focus on species vulnerable to climate change like alpine, island and dryland, arid locations, endemic species, economically important, endangered, human values

7

Example of agrobuodviersity

Mexico’s tomato’s.
Effort to document traditional tomato varieties, in search or those that are high nutrition and climate resilient.
Ensure they are protected in fields and in botanic gardens.

8

What is agobiodiversity

A sub-set of biodiversity that results from both natural selection processes and selection by farmers over millennia

9

Examples of ex situ conservation of fauna

Zoos
Aquariums
Wildlife parks

10

What is the point of ex situ conservation

Entertainment
Systematic collections
Arks of diversity

11

What do conservation centres do

Education
Research
Recreation
Associations with standards and monitoring

12

Example of conservation ex situ

Blackpool zoo

13

How many conservation organisation does Blackpool zoo support

9

14

Which conservation organisations does Blackpool zoo support

Gorilla organisation
Orangutan foundation
Biodiversity and elephant consecration trust
21at century tiger
World parrot trust
World land trust
CBD habitat foundation
SAN Martin titi monkey

15

Who owns Blackpool zoo

Parque Reineunidos - owner of 61 zoos, attraction parks and water parks

16

How many animals in Blackpool zoo

>1,500

17

What bird is critically endangered in Blackpool zoo

Northern bald ibis

18

What are private hobbyist collections

Ex situ breeding of species for personal, rather than commercial or conservation objectives

19

Why can private collections be useful

Potential reservoirs of rare species and have the potential to be bought for consecration.
Not a part of mainstream consecration efforts.

20

Example of a private collection

Spix Macaws.
In 1987; 19 known captive in zoos, 1 in wild.
2000s: two large private collections purchased by conservation groups.
2015: 110 captive birds and plans for breeding and reintroduction.

21

What is commercial breeding

Ex situ beeeding of species for commercial rather than conservation objectives

22

Why does commercial breeding have ex situ implications

Potential reservoirs of rare species.
Not a part of mainstream consecration efforts.

23

Example of commercial breeding for crocodiles

Siamese crocodile.
Native to SE Asia.
Critically endangered and extinct in the wild across most of its range.
>1 million in capacity for leather.
2010: 799 farms in Thailand alone.
Some pure breeds left.

24

Problems with commerical breeding

Hybridisation and artificial selection of the biggest crocodiles

25

Example of commercial breeding for tiger

South China tiger
Critically endangered and probably EW.
1950: 4000 individuals, not sited in 25 years.
2002: save china’s tigers begin work to rewild tigers.
11 cubs and training wild skills in South Africa.
Release sites preliminarily identified.
Questions about viability.

26

What is the aims for ex situ conservation

Insurance against extinction.
Reservoirs for reintroduction.
Stock for breeding new varieties.
Research animal behaviour.
Education.
Fundraising for in situ conservation.
Recreation.

27

How many species are EW

64

28

Examples of EW creatures

Franklin tree
Viviparous tree snail
Pete David deer

29

What does reservoirs for reintroduction require

Genetic diversity.
Assisted reproductive technology.
Eliminate genetic defects.
Control spread of diseases.
Release strategy.

30

Why do you need genetic diversity

For a healthy population, get rid of inbreeding attributes, huge potential for spread of disease
