Ripon Parks

High Batts Nature Reserve is a privately run study resource, and part of Ripon Parks SSSI.[11] It is sited at the north end of Ripon Parks, between the River Ure on the east side, and Hanson's sand and gravel quarry on the west side. It has an annual Open Day, and is accessible to subscribing members, and to visitors by appointment. It includes various habitats, including meadow, coppice, bracken, clearings and an orchid area, plus a stream, pond and bird hides.[12] Training of members in bird ringing, moth trapping and other wildlife recording is carried out.[13]

Birds recorded at High Batts include: marsh tit, redpoll, siskin, great spotted woodpecker,[14] redwing, goldcrest and kingfisher. Fungi include: birch polypore, candlesnuff, dead man's fingers, jelly ear and stump puffball. There are many bryophytes, including three which require a calcareous soil: Entodon concinnus, Thuidium assimile and Ditrichum gracile.[15][16]

In the wetlands are narrow buckler-fern, water violet, common skullcap and marsh cincquefoil. There is also bird's eye primrose, saw-wort, marsh valerian (Valeriana dioica), and butterwort growing around bog rush.[3]

The more unusual plants on the mixed woodland floor are yellow star-of-Bethlehem. and parasitic toothwort colonies.[4][3] The more frequent herbaceous plants here are sanicle, bluebell and primrose. In the woodland understorey are spindle and hazel. The canopy is mostly made up of field maple, sycamore, elm and ash.[3]

The general principle of management of the river is to protect the wildlife habitat, which consists of the water channel, the riverbank and the vegetation upon it.[19]

The channel's form, including natural obstructions such as waterfalls, should be maintained, and artificial modifications should be restored to the natural form where appropriate, to allow fish breeding and movement of wildlife. Channel vegetation should not be cut by more than 50%, to allow seed-setting and wildlife breeding. Exposed river sediment, collapsing banks and timber debris should be left undisturbed, as habitat for invertebrates and other biota. There should be control of invasive species such as Japanese knotweed, Himalayan balsam, signal crayfish and mink. There should be prevention of water pollution where possible, for example, chemicals including phosphorus, and organic pollution, from local and upstream housing, agriculture and industry. Organic pollution should be treated before it enters the river. To prevent soil affecting river ecology, a strip of two metres should be left unploughed along the riverbank.[19]

Floodplains should be maintained as such, or restored where appropriate. Alternative water sources for the floodplain are not acceptable, because the local ecology depends upon the river's mineral content. A variety of vegetation such as grass, fen, scrub and trees should be maintained to promote a variety of flora and fauna. Light grazing by livestock or twice-yearly cutting may be used for this purpose. Riverbank vegetation can be fenced off from livestock to avoid excessive trampling. Any woodland carr, vernal ponds, marsh and oxbow lakes should be maintained to support biodiversity.[19]

Temporary ponds, and ponds without fish, should be maintained as they are, because they support amphibians and certain aquatic plants. Where there is a range of different types of ponds, these should be maintained as such to ensure biodiversity. When a pond becomes silted up, or choked with vegetation, it should be cleared or deepened in small sections to allow recovery at all times. Ponds should be protected from spillages, pollution and entry of nutrients and silt, which would limit diversity of species, or even cause loss of most pondlife. Introduction of coarse fish and the removal of aquatic plants should be avoided, because they disturb the natural ecology. Changes to local land use, especially where water abstraction is involved, should be monitored.[19]

Marshy grassland should be mowed annually, to prevent a prevalence of tall rushes and grasses with dead vegetation below, because this would limit growth of more delicate plants. Annual light grazing by cattle, ponies or hill sheep, between late spring and early autumn, is recommended – although this should not be allowed to disturb marsh fritillary butterflies or nesting birds. A hedge and some scrub is beneficial in an around the marsh. Existing ditches and drains should be maintained in their traditional shape and condition.[19]

Calcareous grassland is at risk of overgrowth by scrub and rank grass, which inhibits specialised vegetation. Light annual grazing and trampling by livestock is recommended, to promote a variety of vegetation, without overgrazing. A small amount of scrub can be permitted for nesting birds and other biota.[19]

Scrub in the UK is defined as small trees, such as juniper, rowan and hawthorn, and bushes. Scrub, and the transitional area between it and adjacent grassland, supports a diversity of species. It should be maintained such that it comprises various heights and densities of growth, with some areas cut to produce patches of grassland. Light grazing may help to manage these requirements. Fencing may be needed in some places to prevent overgrazing or to allow spread of scrub.[19]

The best way to manage woodland carr which includes ash, willow and alder is to leave it alone. Old trees will then fall and create glades, although the environment must be made safe where there is public access. If the woodland appears to be encroaching on grassland and taking its sunlight, coppicing may solve the problem.[19]

In this site it is necessary to protect the habitat of the great crested newt. They need land for feeding and hiding, and water for breeding. Breeding ponds should be unshaded, not too deep, and near other breeding ponds and suitable land. Shallow slopes will allow warming sunlight, and deeper areas will provide safe shelter. Trees, therefore, should be on the north side only, to avoid excess shadow. Newts need aquatic plant cover, but no predatory fish. Late autumn and early winter are the best times for maintenance work to be done here. For foraging, newts need grassland, scrub and woodland close to the pond. They can hibernate in tree roots, under ancient hedges, in rubble, woodpiles and drystone walls. They can travel via ditches and hedges, from pond to pond, if there are no barriers.[19]

The protected habitat sets within this lowland SSSI consist of broadleaved, mixed and yew woodland, neutral and calcareous grasslands, bogs, standing open water and canals, and rivers and streams. Natural England has divided this SSSI into 17 units for assessment purposes, and all were assessed between 2010 and 2013. Six of the units were deemed to be in favourable condition: all the river and stream units (15, 16 and 17); one woodland unit (4, Fox Covert); one standing open water and canal unit (7, Black Heath ponds); one neutral grassland unit (10, Yorkshire Wildlife Trust field).[20][21]

Nine units were judged to be in unfavourable but recovering condition. Unit 1 (High Batts nature reserve), of broadleaved, mixed and yew woodland, was suffering from "insufficient natural regeneration," but was showing gradual improvement. Unit 2 (High Batts calcareous grassland), contained too much burnet rose, but this was gradually being removed. Units 5 (Fox Covert marsh and bogs), 6 (Fox Covert neutral grassland) and 8 (Round Hill calcareous grassland), needed more scrub control and grazing than they had yet received. Woodland units 9 (Sike Wood), 12, 13 and 14 were also adjudged unfavourable but recovering, although no explanation was given.[20][21]

Two units were assessed as unfavourable with no change. Units 3 (woodland by Ure) and 11 (Yorkshire Wildlife Trust woodland), suffered "lack of representative ground flora" due to the invasive species Himalayan balsam and sycamore, lack of regeneration and over-mature trees. Protection of saplings from deer-browsing was recommended.[20][21]

In 1982, Ripon Parks had SSSI status but the designation was not yet enshrined in law due to the Wildlife and Countryside Act 1981 which allowed a three-month waiting period between designation and legal protection. This loophole meant that one 6.5 hectares (0.07 km²; 0.03 sq mi) calcareous grassland-and-marsh meadow on the site was rotovated and reseeded by a tenant farmer. The field previously had 90 different species of plants, including a large patch of marsh orchids. Reed bunting and curlew had nested there. The damage happened because, in spite of a request by the Nature Conservancy Council (NCC), the Property Services Agency (PSA) did not inform prospective tenants of the pending SSSI designation. On 8 May 1982, the NCC informed one new tenant of his obligations of care two days after he had taken over the property, and on 10 May that tenant responded by rotovating the field.[22]

In 2009 Hanson Quarry Products, who ran Ripon Quarry adjacent to North Staining, the River Ure, High Batts and Ripon Parks, made an application to North Yorkshire County Council to extend their works by 98 acres (0.4 km²; 0.2 sq mi). An environmental impact assessment was required because the extension was more than 62 acres (0.3 km²; 0.1 sq mi).[23] As of 2019, Hanson has a biodiversity action plan for Ripon Quarry.[24]

In October 2016, North Yorkshire County Council published a document called Identification of areas of search for sand and gravel, which is intended to provide information which will assist the local authority to plan ahead until 2030 for land use with respect to sand and gravel quarrying, and its effect on the environment and people. Various SSSIs, including Ripon Parks, are considered in this document.[25]

In 1990, the York and Bedale Hunt had a licence to hunt on Ministry of Defence land on the Ripon Parks site. A question was asked in Parliament about it on 5 April 1990 by Mr. Meale.[26]
