1. Biodiversity hotspots Learning intention To understand what a biodiversity hotspot is

2. Starter: What does this map indicate about the global distribution of biodiversity? WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples

3. Activate: What is the nature of the distribution? WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples Biodiversity is strongly linked with latitude. The closer to the tropics generally the more diversity. What sort of countries are these? Why is this a problem? What do these countries lack? The spatial pattern is linked to ‘controlling’ or limiting factors in the amount of primary productivity. The one anomoly is Australia which has high levels of endemism.

4. Demonstrate: What is the global distribution of biodiversity hotspots? WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples Use your map to help you answer this question

5. Activate: What is the nature of biodiversity? WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples According to levels of biodiversity Brazil comes out on top. 750 species of tree 400 types of bird 100 types of reptile 1500 species of flowering birds

6. Activate: What is a biodiversity hotspot? WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples An area containing a huge number of species, a large percentage are endemic. ‘Most remarkable places on earth and most threatened’. Cover less than 2% of earth’s surface yet contain 44% of plant species.

7. Activate: Biodiversity hotspots? WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples Continental hotspots…richest in terms of biodiversity e.g. Cape Floral Kingdom, South Africa Large island hotspots…these are home to diverse and distinctive species which can include relict fauna Small island hotspots…Often low in species number, but have a high proportion of endemics. Susceptible to extinction with small numbers.

8. CASE STUDY: Fynbos, South Africa WALT To understand what biodiversity hotspots are Success Criteria A – Examine the types of hotspots and their location B – Explain what a biodiversity hotspot is C – Describe what a biodiversity hotspot is with examples Major vegetation type of small botanical region. Only 5 other floral kingdoms are known and these cover vast areas. Highest concentration of plant species in world; 1300 per 10,000km2. 70% are endemics. Conversation has become a national priority. Current threats include: Spread of alien plants Commercial forestry Bush fires Building housing estates There are 12 national reserves.
