Winterton beach. Sunset on the dunes. One of the first field trips we went on this year was to Winterton beach in Winterton-on-sea which is a small village located on the east coast of Norfolk. There is an extensive dune system on the beach which is a National Nature Reserve of 109 ha. It is a fairly astonishing site as it has not so many ecological similarities with other Norfolk dunes and more with dune systems in the Baltic as it supports acidic plant communities. There are plenty of ranging habitats at the site including coastal sand dunes and freshwater pools. These habitats have resulted in a large amount of biodiversity being present in the area. Sand dune succession had occurred here just like in any other area with sand dunes. On the embryo dunes the pioneer species was marrow grass which is a xerophyte meaning it needs very little water. It begins to stabilise the dunes so other species such as lyme grass and sea couch grass begin to grow. the next stag...

A grey squirrel foraging for food. The Eastern Grey Squirrel (Sciurus carolinensis)   originates from North America and is easily identified by its grey colouring and bushy tail that is fixed to its back. They source their food from foraging along the forest floor and by climbing trees where they mostly find fruits and nuts or fungi but occasionally they consume eggs or even insects as their diet is omnivorous. Squirrels have even been know to eat young snakes as they have extremely sharp claws which aid hunting and climbing. Their nests are football sized structures made from whatever they can forage such as twigs, leaves  and grass and have the name a drey. A mother and her young will live in the drey but apart for that squirrels don't really interact with other members of their species. They are relatively solitary animals and it is rare to find a scurry (group) of them. They grow to about 30cm and their tails can reach lengt...
