The survey, 80% complete to K<19.2 and complemented by R-band imaging, aimed at investigating whether extremely red objects (EROs) are present in excess around high-z AGN, and to study the environment of z>1.5 radio galaxies and radio-loud quasars. At $18<K<19$ the differential galaxy counts in our fields suggest a systematic excess over the general field counts. At K<19.2, we find an excess of galaxies with R-K>6 compared to the general field.
