Text A is a written piece of information, in the formal register. It has many distinctive features that enhance its purpose, which is to inform readers about the problems in Britain's woodland, and to persuade the readers to donate £2.50 a month to help the problem.
The graphological structure helps the text achieve its purpose in various ways. The text is arranged into clear paragraphs to make it easy to read, and in the middle of the page is a picture of an owl, with woodland scenery in the background. In doing this, the Woodland Trust is trying to appeal to the nature of the readers who find animals cute, to encourage them to donate money.
The leaflet is worded quite personally, with an emotional feel to it. It encourages people to "fight to save Britain's natural heritage". This tries to raise the sense of national pride in the reader, to make them feel a part of it, and to encourage them to join in the fight.
Apart from these exceptions, the leaflet is relatively normal. There is no special or out of the ordinary phonological or grammatical framework used. But, the way in which it is worded, has a special effect upon the reader.
This piece can be summarised as a plea for people to donate money, and in it there is no direct mention of "please donate ..." or words/phrases to that effect. Instead, the reader is told what their £2.50 could do to aid their cause, what it can do to help. At no point does it ask for money, just says how it can save half an acre of woodland per new member. This type of plea would have a better effect on a reader, considering how many charities are advertised asking for donations on television or in leaflets.
