Nature Conservation

Watford Borough Council co-ordinates a broad partnership of local organisations to ensure the nature conservation value of our parks and open spaces is protected and enhanced.

Cassiobury Park

In the last couple of decades Watford has lost a number of open spaces to development, and there continues to be considerable pressure to develop “brown field” sites in the town.  In the past, there was a tendency to “tidy up” or “landscape” open spaces generally and this meant that wildlife was being squeezed out of the Borough.

Watford Borough Council is actively looking at how it can improve the wildlife value of all the sites it manages. Although Watford is a highly urban borough, it maintains conditions for a great deal of wildlife, including rare species, to thrive.

THINKING GLOBALLY, ACTING LOCALLY

It is now recognised around the world that the need to conserve and enhance biodiversity (the full range of plants and animal life around us) is of great importance.

The process began at the ‘Earth Summit’ in Rio in 1992 where the Biodiversity Convention was signed by 167 nations, including the UK.

In response to this plan, the Hertfordshire and Middlesex Wildlife Trust have produced a Biodiversity Action Plan (BAP) for Hertfordshire, with support from English Nature, the Environment Agency and local authorities. The plan urges local authorities to protect what remains of their semi-natural habitat. It particularly advocates that all land managed by local authorities should be managed in a way which promotes conservation.

Watford Borough Council will be producing its own Local Biodiversity Action Plan, based on the County BAP. This will be the means by which the Council can fulfil its own biodiversity obligations. Specific sites in the borough, detailed below, are protected for their biodiversity and have also been targeted for the rehabilitation and re-creation of habitats, where it is feasible.

NATURES RESERVES MANAGED BY WATFORD BOROUGH COUNCIL

The most important wildlife sites in Hertfordshire have been designated ‘County Wildlife Sites’. They are the wildlife ‘jewels in the crown’. A number of these sites are owned and managed by Watford Borough Council. Descriptions of some of those sites, and what you might find there, are given below. Most of the sites now have ‘Friends’ groups, made up of local residents, and there are many opportunities to help protect and enhance your local area. Contact details for the ‘Friends’ groups for each site is given under each description.

  • Bird species include: greater spotted woodpecker, nuthatch, treecreeper, as well as thrushes, finches and tits and, in the spring, chiffchaff and blackcap. Butterflies include purple hairstreak and speckled wood.

CASSIOBURY PARK

Entrances: Shepherd’s Road, Rickmansworth Road, Gade Avenue, Coningesby Drive, Parkside Drive
Status: Local Nature Reserve, County Wildlife Site, Invertebrate Site
Description:

  • Cassiobury Park is a large park of great local heritage importance and rich in wildlife. It has a variety of habitats, including the River Gade and the Grand Union canal. Other wetland includes: streams, ditches, springs, ponds and watercress beds. There is also wet grassland and carr woodland (wet woodland). Elsewhere there is acid grassland and veteran trees that provide mature and dead wood niches.

  • The wet areas in the park are important because areas of open water, marsh and alder carr are uncommon in Hertfordshire. Only about 114 hectares of fen or marsh habitats now remain in Hertfordshire. Key habitats that are locally rare, or threatened, and require conservation action include: tall fen swamp, Alder carr, Chalk stream and acid grassland. Although watercress beds are artificial, they support a scarce associated fauna, similar to chalk streams, and this is one of only two left in the County.

Some examples of the park's wildlife richness are given below.

  • Plant species include: water-crowfoot, common water starwort, water plantain and celery-leaved buttercup

  • Birds include: song thrush, all three species of woodpecker, grey heron, moorhen, swan, kingfisher, grey wagtail, teal, green sandpiper, water rail and mallard and in the spring/summer, blackcaps and chiffchaffs are heard. House martins, swallows and swifts can be seen feeding on insects over the park. In the winter snipe, redwings, fieldfares may be seen.

  • Mammals include: pipistrelle, water shrew. Water vole was present recently, but now appears to be extinct in the park.

  • Amphibians and reptiles include: frogs, toads, smooth newt and grass snakes

  • Fish and molluscs: swan mussel, nerite, bullhead

  • Insects: Includes two red data species, both flies, Parhelophilus consimilis and Vanoyia tenuicornis. There is an abundance of dragonflies, including the banded demoiselle and southern hawker. Marbled white butterflies have appeared for the past two summers, since the grass cutting regime was changed between the river and Rickmansworth Road.
