We show here how, through the efforts of a range of governmental and non-governmental organisations, habitats and species are now being managed to preserve our biodiversity for the future. In this period of rapid environmental change and ever increasing human impact, the success of such conservation initiatives has never been more vital. Over the past half-century there have been many changes in the Yorkshire countryside. Deciduous woodlands have been felled and replaced by conifer plantations; wetlands and ponds have been drained; grasslands have been reseeded, and arable fields have been intensively farmed. Our river systems and coastline have also been subjected to increasing pressure and pollution. All these changes have had dramatic effects on YorkshireÕs semi-natural habitats and their associated wildlife. Added to these effects, our climate is altering more rapidly than at any time in the last 10,000 years, leading to further challenges for plants and animals.
