Practical 3 ex-situ Conservation:

Zoos & Botanical Gardens

Reading

Primack, R.B. (1998). Essentials of Conservation Biology 2nd edition. Sinauer

Associates, Sunderland, Massachusetts. Chapter 14 Ex situ Conservation Strategies

Introduction

The best long-term strategy for protecting biodiversity is the conservation of naturalpopulations and communities in their natural habitat (in situ). However, for many species

this is no longer an option, and it is argued that the best alternative is to maintain

individuals under artificial conditions managed by people. This is called ex situ or off-

site preservation.

Facilities for ex situ preservation of plants and animals include zoos, aquaria, captive

breeding programs, game farms, botanical gardens, arboreta and seed banks. This

practical asks you to focus on two aspects. Firstly, to become familiar with biological

diversity at a global scale by visiting a zoo and a botanical garden, and secondly to

discuss the merits, shortcomings, and the ethics ofex situ conservation.

The task

Visit a Zoological Garden and a Botanical Garden (or a regional zoo/fauna park/garden).

If you cannot get to one, visit a virtual zoo or virtual garden on the web. A few web

sites to visit at are listed at the end of this practical, but you will find lots of sites if you

search around.

Your Report

Your report for this practical consists of two parts (1) a group presentation) and (2) an

individual written report.

Part 1 In a group of no more than three students, prepare a 10 minute presentation to be

given to your class, in which you describe how the survival of one plant or one animal

you observed is being assisted by ex situ conservation strategies. If possible, use some

images to illustrate your presentation.(Carry this out in PCK 2)

Part 2 Discuss in an individual essay-style report of about 300 words, the issues

below. Include a brief statement of the aim of the prac, and remember to cite your

references in the text and provide a reference list at the end in the correct format.

What range of diversity is present ? How representative of total biodiversity at

(a) a national and (b) a global level are these zoo and garden collections? Do they

focus on particular groups and underrepresent others ? Explain.

What do in situ and ex situ mean ? What are the merits and shortcomings of ex

situ conservation ?

Why do some ecologists believe that in situ conservation, by careful habitat

management, is the only acceptable conservation strategy, and that it is

unacceptable to maintain species which no longer have any natural habitat, or

who are unable to breed in the wild, in zoos/gardens?

Why do many people think it is not right to attemp to bring back extinct

species such as the Tasmanian tiger? What are the conservation implications of

these types of actions?
