"The Living World is the next best thing to being there. Our contributors are skilled naturalists who are able to reveal those fascinating facts about animals and plants that you don't always find in books. It's like having a personal guided tour of the countryside, without needing to leave the house."

Bracken - the most successful and adaptable fern in the UK.
|
Ferns
While ferns are thought of as delicate and sensitive, many species make the most of exploiting all sorts of habitats.听
Bracken is perhaps the most successful and adaptable of ferns but there are other ferns not quite so hardy-looking that will set up home in any nook and cranny where their tiny spores settle.
In the city of Bath, and many other cities, native and alien fern species can be seen in the sheltered stairwells and basement areas of the old Georgian and Victorian townhouses.
The leaves or fronds of ferns come in a great array of shapes and sizes and provide a flash of welcome winter green in their glossy green and olive colours.
Ferns reproduce by producing spores within sporangia to be found on the underside of the fronds. Thousands of spores are produced.
Some ferns can also reproduce vegetatively, like bracken. And another group of hybrid ferns have been found to reproduce by apogamy where no form of fertilisation is needed for a sporophyte to be produced. |
