Habitat Management

Habitat Management focuses on the practical strategies used to maintain and restore ecosystems. Students explore the design of nature reserves, the role of corridors in connecting fragmented habitats, and the controversial but increasingly popular concept of rewilding. This unit also covers ex-situ conservation methods, such as captive breeding in zoos and seed banks, and their role in supporting in-situ efforts as outlined in AQA 3.2.3.

Activity 01

• Simulation Game
• 55 min · Small Groups

Simulation Game: Designing a Nature Reserve

Groups are given a map of a fragmented landscape and a budget. They must decide where to place protected areas and wildlife corridors to maximize species survival, using principles of island biogeography. They then 'test' their design against a simulated development or climate event.

Activity 02

• Formal Debate
• 45 min · Whole Class

Formal Debate: Rewilding vs. Traditional Management

Divide the class into proponents of 'passive rewilding' (letting nature take its course) and 'active management' (maintaining specific successional stages). Students use UK case studies like the Knepp Estate to argue which approach is better for maximizing biodiversity in a crowded country.

Activity 03

• Stations Rotation
• 40 min · Small Groups

Stations Rotation: Ex-Situ Conservation Methods

Stations cover seed banks (e.g., Millennium Seed Bank), captive breeding programmes, and cryopreservation. Students rotate to identify the pros and cons of each method and discuss how they can be integrated with habitat restoration projects.

A few notes on teaching this unit

Watch Out for These Misconceptions

• Zoos are the main way we save endangered species.

  Students often overemphasize captive breeding. A collaborative investigation into the high costs and low success rates of reintroducing captive-bred animals helps them understand that habitat protection (in-situ) is almost always more effective and sustainable. Peer discussion helps clarify the supportive role of zoos.

• A 'natural' habitat is one that is left completely alone.

  In the UK, many high-biodiversity habitats like hay meadows or heathlands require active management (grazing, mowing) to prevent them from turning into scrubland. Using a 'succession sorting' activity helps students see why human intervention is sometimes necessary to maintain specific ecosystems.
