Rayleigh Sewage Treatment Works.

The treatment works lies south of Hockley woods and north of the residential part of eastern Rayleigh. In addition to having those building and structures one would normally associate with a site such as this, there are open, wet fields, hedgerows and woodland either within the boundary of the works or very adjacent to it. The brook which flows immediately to the south may have an effect on the birdlife of the site, though this influence is nothing like as marked as that associated with the woodland which borders the area to the north and south.
The woodland here is predominantly oak and hornbeam and many of the bird species identified during the eleven months of the survey might more commonly be expected in that habitat rather than the sewage works itself.
Bird species found there way into the survey figures only by being present within the area surveyed; it would be reasonable to speculate that some species may have been entirely absent from the survey had it not been for the adjacent woodland.
