Transcript Conservation of Habitats

Conservation of
Habitats
Starter task: List as many
endangered species as you can…
Objectives
Outline how conservation can be
carried out to protect species and
habitats.
Outcomes
(3) Describe what conservation is.
(5) Explain how to conserve habitats
using the concept of succession.
(7) Evaluate how best to conserve
species comparing different habitats.
Key terms: Conservation, succession, biodiversity.
What is Biodiversity and why do
we care about it?
How do we know how diverse an
environment is? (think back to
the field trip!)
Outcomes
(3) Describe what conservation is.
(5) Explain how to conserve habitats
using the concept of succession.
(7) Evaluate how best to conserve
species comparing different habitats.
Key terms: Conservation, succession, biodiversity.
Outcomes
(3) Describe what conservation is.
D= diversity index
N= total number of organisms
N= individuals of a species
(5) Explain how to conserve habitats
using the concept of succession.
(7) Evaluate how best to conserve
species comparing different habitats.
Key terms: Conservation, succession, biodiversity.
Which of these are endangered?
Conservation
• Maintain ecosystems and biodiversity.
• Ethical – respect cohabitation.
• Economic – lose gene pool = valuable.
• Cultural and aesthetic – inspiration and
enrichment!
Question
How can we conserve species
using succession?
Outcomes
(3) Describe what conservation is.
(5) Explain how to conserve habitats
using the concept of succession.
(7) Evaluate how best to conserve
species comparing different habitats.
Key terms: Conservation, succession, biodiversity.
Managing succession
• Out competition in earlier stages than
climax community.
• Prevent from going to next stage.
• UK – moorland burn
heather and sheep
graze
Task
It has been decided that the
Manila needs a zoological park. It
is up to you to:
1.
2.
select a suitable site from a
shortlist
select three priority species
for conservation.
Outcomes
(3) Describe what conservation is.
(5) Explain how to conserve habitats
using the concept of succession.
(7) Evaluate how best to conserve
species comparing different habitats.
You should give reasons for your
selections.
Key terms: Conservation, succession, biodiversity.
1. a) Give 2 aims of biological conservation.
b) The graph shows the rate of extinction of species of
birds on islands of different sizes.
Rate of
extinction
of species
Area of island
i) Describe the relationship between the rate of
extinction of species and the areas of the islands.
ii) Suggest one cause of this relationship.
1. (a) to maintain diversity;
to maintain organisms’ habitats/ecosystem; 2
(b) (i)
exponential relationship/described;
smaller the area, greater the rate of extinction; 2
(ii) one reason, explained, e.g. :
smaller areas are/have (many) fewer
species/number of individuals
and thus smaller/less stable communities;
greater chance of competition;
human impacts more damaging;
diseases spread more easily;
greater impact of new diseases/predators;
smaller number of sites meeting niche of
species; 1 max
Essential Questions
Does biodiversity matter?
Do we have a moral obligation to protect species?
Do all organisms matter?
Objectives
Outcomes
Evaluate the success of a named
protected area.
(3) Explore the success of different
conservation methods.
Discuss and evaluate the
strengths and weaknesses of the
species based approach to
conservation.
(5) Describe the benefits and
drawbacks of different conservation
methods
(7) Evaluate a range of conservation
methods; carefully considering
issues such as funding, value and
community support.
Key terms: aesthetic, ecological, breeding program, zoo
Task
Outcomes
Choose one protected area.
(3) Explore the success of different
conservation methods.
Background information.
Why was it set up?
What have been the successes?
What are the current issues?
(5) Describe the benefits and
drawbacks of different conservation
methods
(7) Evaluate a range of conservation
methods; carefully considering
issues such as funding, value and
community support.
Key terms: aesthetic, ecological, breeding program, zoo
All protected areas need key
three things:
•Community support
•Funding
•Research
Why?

methods; carefully considering
issues such as funding, value and
community support.
Key terms: aesthetic, ecological, breeding program, zoo
Tasks
Outcomes
1.For each named method come up with a list of
benefits and drawbacks.
(3) Explore the success
of different conservation
methods.
2.Choose one method to fully evaluate.
•Captive breeding programs
•Reintroduction programs
•Zoos

benefits and drawbacks
of different conservation
methods
(7) Evaluate a range of
conservation methods;
carefully considering
issues such as funding,
value and community
support.
Key terms: aesthetic, ecological, breeding program, zoo
Aesthetic vs ecological value
What do the two mean?
