Points of Conservation Significance at Hylands Good range of habitats within the wood-pasture, including ancient woodland, calcareous to acid grassland, good numbers of veteran trees, still and running fresh water and good quantity of dead-wood Healthy biodiversity, but concentrated in some parts of the park Virtually no pesticides used in the wider park - ie fungicides or herbicides. Grasslands not treated with fertiliser. Some herbicides used in formal gardens - it would be helpful if fungicides or fertilisers were not considered for use on some of the older lawns Now that the formerly cultivated fields in the north part of the park have been reclaimed, there is no ploughing at Hylands - deep ploughing can disturb the root-plates of veteran trees and pesticides and fertilisers used on crops can also be detrimental The large (577 acres) compact size of Hylands is good for conservation and since a past owner (J. Attwood) closed the roads and presumably shut-off the footpaths (ie terminated all public access) the park has no problems with excessive vehicular traffic or its associated immediate pollution It is a working wood-pasture of sorts, with the grasslands being cut for hay and at least some grazing pressure being maintained by a herd of fallow deer The trees are probably some of the best managed veteran trees in Essex Currently very well-managed for its wildlife, much more should be made of its potential for education in the sphere of conservation management of historic park landscapes Only moderate human disturbance for most of the year Fifty-nine Red Book Data Book or nationally notable species recorded from the park Home to some 150+ species of saproxylic invertebrates Fourteen Biodiversity Action Plan species recorded Essex Parks: Section 2 - Hylands Park 167
