Wind are important to habitats as they cause water currents and waves , and also carry rain bearing clouds. In Nigeria, the winds influence the climate, with the dry harmattan from the Sahara causing a cool dry season and the rain bearing south westerly winds from the ocean causing a humid rainy season. The winds are, therefore, partly responsible for the local biomes in Nigeria. The winds are also responsible for the climate and vegetation of mountainous regions, with the windward side being wet with luxuriant vegetation, and the leeward side, dry with space vegetation.
Winds helps in the dispersal of fruits and seeds and cause pollination in some plants especially grasses. They are thus partly responsible for the distribution of plants in various habitats. The drying effects of strong winds cause high transpiration rates. This affects the kind of plants that are found in regions exposed to such winds.
In a given area, insects have been observed to spread faster in the direction of the prevailing winds than in the other directions even though the whole area seems to offer equal opportunity for the establishment of the insect species. Thus , wind direction plats an important role in the establishment of insects in a given area.
