The distribution of ecosystems are determined by the , such as rainfall and temperature. These are influenced by latitude and cells. However there are local factors involved too - such as altitude, relief, aspect and geology. In the , it is colder, and ecosystems might be classed as Alpine. In the UK, the climate is warmer than expected because of currents. In the UK our climax vegetation type is deciduous . Trees such as oak, ash and birch grow during the spring and summer, but when arrives, they drop their leaves so that the trees don't blow over in winter storms, and with shorter, colder days, the leaves can't earn their keep in terms of photosynthesis which outweighs their maintenance. This means that there is a thick layer on the floor. Woodlands are home to a rich variety of species - millions of insects live within the trees, which are preyed upon by birds and small mammals. Caterpillars eat holes in their leaves, and other insects live in the bark. Trees also make good nesting sites for birds.
A smaller example in an agricultural setting is a . They provide local habitats for plans, animals and insects and are important corridors for the species to travel. However hedgerows are under threat from farmers who want bigger to they can use bigger, more efficient equipment. Similarly, woodlands are under threat from developments such as pressure to build more , or to build new roads and railways. Removing habitats is not only damaging ecologically, but they are a carbon , helping to mitigate the severity of change.
