Cottage Bottom Fields



As you walk around, you will notice that there are areas of short grass, long grass, shrubs and woodland planted in 1980. These different habitats suit different plants and a great variety of insects. They also provide food and shelter for many birds and mammals. This leaflet looks at just a few of the plants that you can see at the reserve and the insects that depend upon them for their survival.

Short Grass Some of Britain's loveliest wild flowers, such as the pyramidal orchid shown on the front of the leaflet, grow in short grass on chalk hills. The grass is best kept short by grazing animals and at certain times of the year there will be cattle, sheep or even goats grazing at Cottage Bottom Fields. From about mid-May to September, you may catch a glimpse of the common blue butterfly, which lays its eggs on bird's foot trefoil. The males have lilac-blue upper wings and silver grey under-wings with small rings on them.


Long Grass The marbled white butterfly appears in June and prefers longer grass and feeds on tall grassland plants, such as field scabious. The caterpillars feed on grasses like red fescue and timothy grass.
Roesel's bush cricket is a recent addition to the reserve, having migrated from Hertfordshire in the hot summer of 1990. They are now well established at Cottage Bottom Fields and can be seen in the late summer.


Scrub Since the war Cottage Bottom Fields has not been grazed and this has allowed the hawthorn shrubs to take over, shading out much of the grassland. Recent management work has involved removing these shrubs or scrub to encourage the grasses and wildflowers to grow again. However, many animals rely on scrub for shelter and food, and so some of the shrubs will be left and small glades created between them. The gatekeeper butterfly, for example, never strays far from shrubs or the tall grasses growing near them. It has orange and brown wings and can be seen from mid-July to August.


Woodland Trees have been planted on two fields that had been ploughed to grow cereals. The new woodland includes Corsican pine and larch, with Norway maple, hornbeam, oak, beech, ash, field maple and cherry.
Along the northern boundary a strip of land has been left to develop naturally. Here young ash trees are now growing amongst the scrub and, in the long term, this area will become woodland too.


Visits to the Reserve Visitors are welcome, but there is no parking at the site. The reserve is easily reached on foot from Dunstable along the Icknield Way or as part of a number of walks in the north Caddington area.
Please enjoy your visit and look after the reserve by:
• Keeping dogs under control especially where animals are grazing
• Not picking wildflowers
• Taking all litter home
• Guarding against fire
• Keeping to the paths
