The Woodhall Estate is actively committed to nature conservation and the management of wildlife habitats for the long term. It harbours a diverse and valuable range of species including birds, butterflies, bats, badgers, invertebrates and fungi.

Due to the wealth of wildlife interest on the estate, some of its farmland has been accepted into a Higher Level Stewardship Scheme managed by Natural England. Of particular relevance are management initiatives to support and enhance farmland birds, especially yellow hammer, skylark, grey partridge, corn bunting lapwing and tree sparrow.

There is an active hedge planting and management scheme which includes the maintenance of field headlands and margins for the benefit of wildlife.  Woodland rides and glades are also managed to improve habitats and enhance diversity.  Dead wood, both standing and fallen is given specific attention as it provides an important habitat for fungi and invertebrates, which in turn supports woodpecker, tree creeper and other associated species.

The River Beane, the source of which is some 3 miles to the north, flows through the estate and joins the River Lea in Hertford.  Geese and swans and many varieties of duck are at home here and numerous waterbased plants exist along its banks.
