The graph below shows the population figures of different types of wild birds in the United Kingdom between 1970 and 2004 Summarize the information by selecting and reporting the main features and make comparisons where relevant

The graph indicates the indicator rate of various categories of wild birds between the years 1970 and 2004 in the United Kingdom. It uses an index starting at 100 in 1970 and the symbol are shown yearly. The all species kind show the overall indicator between coastal, woodland and farmland species. It shows a growth from 100 to 110 by the year 1977, after that it fluctuated widely between 110 and 100 indicator points. There is a rise in coastal species from 1970 to 1980 when the price reached a peak at 135 indicator mark, then, there is a fluctuation, until 2004, keeping similar figures. There is a rose on woodland species from 1970 to 1972, reaching a high at 110 stop, after that the graph shows a downward trend, reaching 85 index mark in 1992, after that, the symbol remained steady. The fourth level, farmland species reached 110 indicator stop in 1776, after that the population dropped dramatically, showing 55 mark in 1998, being this the lowest mark reached by the four kind represented. Coastal species is the only group above the overall, showing the most essential growth, while the farmland species population plunged. Woodland species displays a decrease in its rate, below the species grade.
