1 The Essex Naturalist first appeared in January 1887. This issue thus stands as that for the eightieth year. This is a record in which the Essex Field Club may justly feel pride. In eighty years an immense volume of knowledge of our county has been distilled and for ever recorded in its pages. These years have seen many changes; not the least being that the early parts of our journal appeared at monthly intervals, in contrast with our present annual publication. Essentially, however, the contents of The Essex Naturalist are little changed. We are still in the process of taking stock of our county's flora, fauna, past history and geology. This should not be taken to imply that we have not progressed with the times. In an era offering unrivalled opportunities for learning and travel to advance our interest in nature, it demands very special discipline and qualities to explore and study in depth our Essex countryside. In following this tradition of the great English naturalists, John Ray and Gilbert White, we derive pleasure, but also contribute much to general knowledge. To-day, the necessity for taking stock of our own county and putting it on record is more urgent than ever. The threats posed by motorways, major airports and inevitable urbanisation under- line the need to record what is present before irreversible changes make it for ever impossible. Before we celebrate the centenary of The Essex Naturalist the face of our county will have suffered major alteration; it is for us to provide future generations with some image of its present condition.
