Wildlife in City Gardens: Project Findings and Insights
ANNOUNCER: Section 4. You will hear a talk about a project on wildlife found in city gardens in Britai
. First, you have some time to look at questions 31 to 40. Now listen carefully and answer questions 31 to 40.
SPEAKER: Good morning. Today I'd like to present the findings of our Year 2 project on wildlife found in city gardens.
SPEAKER: I'll begin by talking about the background of the project, then explain our research methods, and finally present some interim findings.
SPEAKER: The topic came up during a discussion among our group of four students. Two members mentioned seeing increasing numbers of sparrow hawks in their city centre gardens.
SPEAKER: These are one of Britain's most interesting birds of prey, and we wondered why they were appearing more often in urban areas.
SPEAKER: This led us to explore why wild animals are increasingly choosing city gardens when the countryside seems to be becoming less suitable for them.
SPEAKER: First, we calculated how much urban land is occupied by private gardens. Our estimate was about one-fifth, and official land survey data confirmed it was 24%.
SPEAKER: Informal discussions with neighbours and friends also revealed that many people had interesting experiences with wildlife sightings.
SPEAKER: So we carried out a survey of garden owners from different parts of the city.
SPEAKER: More than 100 participants completed a survey every two weeks for 12 months.
SPEAKER: They recorded species they saw using a standard list and added any rare species.
SPEAKER: At the same time, our group conducted direct observations in selected city gardens.
SPEAKER: We deliberately chose small gardens, because they are the most typical in urban environments.
SPEAKER: Our aim was to study the normal situatio
, not unusual examples.
SPEAKER: Alongside this research, we also read many books about the decline of wildlife in rural areas.
SPEAKER: Our results produced a lot of data, but today I'll discuss only three species that illustrate important trends.
SPEAKER: The first species is frogs. Their numbers increase where there is suitable water.
SPEAKER: Garden ponds are becoming more common, while rural ponds are disappearing.
SPEAKER: As a result, frogs are migrating to towns.
SPEAKER: The second species is hedgehogs. They survive better in cities because their predators remain mainly in rural areas.
SPEAKER: We recorded many sightings, so we were able to count their populatio
quite accurately.
SPEAKER: The final species is the song thrush, one of the finest singing birds.
SPEAKER: Although declining in the countryside, it is increasing in urban gardens.
SPEAKER: One reason is that gardeners now grow a wide variety of plants, providing plenty of seeds for birds to eat.
SPEAKER: Another factor is the availability of nesting places, which are often better in gardens than in the countryside.
SPEAKER: Interestingly, a new large-scale song thrush survey is about to begin, so watch out for it.
SPEAKER: Now, I'd be happy to answer any questions.
ANNOUNCER: That is the end of Section 4. You now have half a minute to check your answers.
