The Blashford Lakes Nature

Reserve encompasses approximately 360 acres of this wider area, In addition, education activity on site is supported by three Outdoor including Water, Ellingham Lake, Ivy Lake, Blashford Lake and the Learning Tutors employed on a sessional basis. land surrounding them. There are a wide variety of habitats (lake, pond, river, ancient woodland and secondary woodland, grassland and reedbed). Not withstanding extraordinary circumstances, the nature reserve is open As a result its wildlife is very diverse and it is an attractive destination for daily, from 9am-4.30pm, 364 days of the year. visitors throughout the year.

For more information and links to the reserve blog and events programme The Blashford Lakes are important nature conservation habitats, recognised by national and international designations (SSSI, SPA and see:

SAC) for migratory over-wintering wildfowl. Most activity by the Blashford www.hiwwt.org.uk/nature-reserves/blashford-lakes-nature-reserve Project occurs on and around Ibsley Water and Ivy Lake - the lakes and www.hiwwt.org.uk/education-centres/blashford-lakes-education-centre adjoining tracts of land provide a significant recreational resource for local residents, with an extensive educational role provided through the Blashford Lakes Centre. This was opened in 1996 by Professor David Bellamy and general public access to the nature reserve has been permitted and promoted since 2006. During that time the permissive footpath network has been extended to 8km of rolled gravel footpaths and the reserve also boasts 10 bird watching hides and screens. Ease of accessibility has been considered throughout the reserves development and as a result the reserve is visited and enjoyed by people of all ages and physical abilities.

During this period the Project has benefitted significantly from an extensive programme of visitor improvements with funding from New Forest LEADER, Veolia Environmental Trust, with money from the Landfill Communities Fund and generous public donations.

The nature reserve is managed as the Blashford Project by Hampshire and Isle of Wight Wildlife Trust in partnership with the landowners of the site Bournemouth Water and Wessex Water.

Blashford Lakes Annual Report 2018-2019 2. EDUCATION OVERVIEW

This reporting period saw education and engagement with over 4,000 activity participants this year. The fall in overall participation from last year 6000 is in part attributed to several periods of time throughout the peak summer term during which we did not accept bookings in order to accommodate the 5000 construction and development works on site and/or in the centre, and in part due to a reduction in events, including Reserves Officer led guided 4000 walks – the additional workload associated with overseeing contractors and preparing the site for the project work restricting our capacity to promote 3000 and deliver engagement activities in the late Winter and early Spring. 2000

A third contributing factor to the decrease in engagement was a reduction 1000 in staff capacity; following the completion of the “Natural Wellbeing” Inclusion Recovery funded project in October 2018, the Assistant Education 0 Officer dropped from 5 days to 4 days per week for the period of March – June 2019 which limited the size of the groups that we were able to accommodate on one day a week during that time. The number of public events held was also significantly reduced by the cessation of the “Natural Wellbeing” weekly sessions in October also.

Austerity continues to impact on how and when schools visit us. Despite the various factors listed above that limited the number of individuals engaged with over the course of this period, although we did not have as 2500 many day visits from schools this year as we have done in the previous 5 years, the number of children that we worked with actually rose. With

school budgets being managed as tightly as they are we are finding that the 2000 size of groups is increasing: schools that historically would have come a class at a time over several days are now bringing two or three classes on

the same day thus reducing their transport costs, but unfortunately reducing 1500 the quality of the experience for the children due to the greater number of children involved in any one activity at any one time.

Another impact of austerity continues to be that of when schools come – 1000 with a focus very much on the summer term and fewer Autumn bookings participantsofNumber compared to the number we had in September, October and November before the recession. 500

As discussed in the overview on the previous page, although this year has seen a slight fall in the number of school visits from 50 to 46, in part due to a continued suppression in Autumn bookings and in part due to planned closures to facilitate the Centre and site development works this summer, the number of individual children engaged with has actually increased significantly, with the total number of Primary School aged children increasing by more than a 1/3 of last years total.

The nature reserves fantastic variety of habitats, all easily accessible and within a short walk of the centre and each other, coupled with its well equipped classroom, all important handwashing/toilet facilities and experienced staff and volunteers, continue to be extremely appealing to local schools and colleges of all ages and abilities.

Although a range of outdoor learning opportunities are offered at Blashford Lakes, from natural art to basic bushcraft, it is still those science and geography based activities around habitats, field work and river study which continue to be those most frequently requested and delivered, as the graph opposite clearly illustrates.

“I just wanted to personally thank you and your colleagues and say how impressed I and my colleagues were with your expertise and leadership. Thank you again for the excellent trip - I will be recommending the centre to friends and colleagues - and will hopefully see you again in the future!” Class teacher, Burley Primary School

Blashford Lakes Annual Report 2018-19 Although the number of adult community and/or special interest groups 2.2 Informal education program has remained consistent at a little under 300 individuals, this reporting period has seen a small decrease in the number of groups of children and 2.2.1 Youth organisations/community group visits young people visiting with their group. It is a relatively small decrease, and the 413 individuals we did work with is broadly comparable with the average of 500 over the last 10 years and, as indicated elsewhere in the Number Total 5 to 12 to report, this small decrease is not unexpected given the planned closures of < 5's Adult number of 11's 25's for development works over the summer and a reduction in Assistant groups participants Education Officer hours over the summer term. 30 21 339 53 285 698 What we have delivered however continues to be done to a high standard and includes innovative projects such as the “Bird Trail” event for groups of children and young people organised in partnership with Hampshire Ornithological Society, held in May, which saw 10 teams joining us from a range of organisations, including both uniformed groups and children’s natural history groups.

A day long event incorporating HOS led bird watching and identification, a bird ringing demonstration by British Trust for Ornithology volunteers (and Blashford bird ringers) Kevin Sayer and Brenda Cook, a birds of prey display by Liberty’s Owl, Raptor and Reptile Centre, a ground nesting bird awareness raising activity with the New Forest National Park Authority and pond dipping, river dipping, owl pellet dissection and moth identification with Wildlife Trust staff and volunteers.

Education staff and volunteers have provided a varied programme of public events, walks and activities throughout the year, suitable for adults and families of all ages.

The fall in numbers engaged with overall during this period can largely be attributed to a lack of capacity on behalf of the Reserves Officer to lead guided walks and to the fact that a large number of older Wildlife Tot pre- school aged children all “came of age” and left us for school at the same time. 8 Wild Days Out: wildlife, wild play, wild cooking – and wild (happy!) children © HIWWT

The addition of a green roof helps the whole structure 6. ACCESS AND INTERPRETATION to merge more effectively with the surroundings.

The main focus of work in the winter period was on the replacement of the Tern Hide, and improvements to the Main Car Park area, the redevelopment of the area around the Education Centre, the installation of a new Welcome Hut, building a new dipping pond, restyling the Education centre foyer, installing new wildlife cameras, wildlife sculptures and the resigning of the whole site. This work comprised two projects funded separately by Veolia Environmental Trust and New Forest LEADER, each with different completion dates, between them they have significantly revitalised the reserve some 24 years after it was originally developed. The work involved seven different contractors and was achieved with relatively little disruption to general reserve visitors and it was possible to keep the reserve open throughout with only local restrictions.

6.1 New Tern Hide

The new Tern Hide was funded by a grant from the Veolia Environmental Fund, with match funds raised via a very successful public appeal. The decision to replace was prompted by the failing of the wooden floor of the old hide, probably encouraged by the occasional flooding of water under the hide when the Dockens Water overflows during high rainfall events.

6.3 Front of Education Centre and Welcome Hut In order to facilitate the new landscaping and Welcome Hut it also proved necessary to completely relevel the car parking beside the Centre to The area around the Education Centre was redeveloped, the creation of a ensure drainage was maintained. The parking area was also slightly safe, car-free area in front of the Centre was achieved using a reshaped to ensure that the space could be used to maximum effect. As a combination of fencing and planters. This provides a gathering area result, despite quite a large area of former parking being taken up by the separated from the car park as well as additional seating for visitors. now car free frontage of the Centre, the car park capacity was only reduced by about two spaces. A new Welcome Hut just beside the path to the Woodland Hide has proved very popular and provides a focus for visitors seeking information about the reserve. This has proved particularly popular with first-time 6.4 New Dipping Pond and rear of Centre visitors. The hut is served by volunteers and is open on most days of the week, year-round. To the rear of the Education Centre a new pond was constructed for educational use. Pond-dipping is one of the most popular activities and a second pond will ensure that use can be spread and so reduce the impact of frequent use. The new pond uses a traditional liner with a boardwalk access for pond-dipping. Once constructed the surrounding area was planted up by the volunteer team. A large “bug hotel” was added by the Young Naturalists. In addition, the old pond needs relining as it is leaking and the second pond allows continued opportunity to undertake the activity whilst this is done. Fortunately, a wet spring enabled the pond to be filled with rainwater collected from the Centre and shelter rooves.

In addition, the gravel area to the rear of the shelter was extended and extra picnic tables added, these can be used both for pond-dipping activity and for their designed use.

The project also saw the replacement of the majority of the old picnic tables with new ones. A range of designs have been bought, the accessibility of these tables varies and different designs suits different users, two of the new designs are of a larger type with enhanced wheelchair access.

6.6 Centre Foyer

The foyer and toilets were repainted and the displays in the foyer renewed. A feature of this are the large silhouette shapes that cut across the doors, a style that mirrors that of the new outdoor site signage.

This project has included a new donations box and a contactless donations point, a recognition of the fact that increasingly people are carrying less cash than they used to, resulting in an inevitable drop in cash donations.

A key element of the foyer refresh was the installation of a new screen for viewing the wildlife cameras, referred to above.

6.7 Signage

Perhaps the most immediate impact of the many works undertaken is the new reserve signage, particularly the main entrance board on the south side of Ellingham Drove, which includes a striking cut out in the shape of a kingfisher. This alone seems to have brought in several new visitors The new dipping pond being filled © Bob Chapman who were just passing the site and made curious by the sign. The Welcome Hut volunteers ask if visitors are new to the site, and whilst new visitors will be more likely to seek assistance, it is clear that we have had 6.5 Wildlife Cameras a surge in first time visits over the last year.

6.9 New Tern Raft on Ibsley Water

There have been small tern rafts on Ivy Lake for many years and these have been well used by nesting terns and latterly, black-headed gulls. There had long been a desire to place a raft on the much larger Ibsley Water, however the small rafts would be likely to get swamped on such a large body of water where quite large waves can be generated. The project funding allowed the construction of a much larger raft for deployment on this lake and this was constructed by the conservation volunteers in early summer. It was too late for any nesting to take place in 2019, so 202 will be the first season in which it will be available.

6.10 Badger sett

Another volunteer project that formed part of the project was the construction of an artificial badger sett. This has a wildlife camera installed and can be viewed on the screen in the Education Centre foyer. So far no badgers have been seen using the sett, but it was always likely that it would take time, so we remain hopeful of occupancy at some stage.

7.3.3 Acidic grassland was grazed off by either deer or rabbit before it set seed. Once again there was a good show of Autumn lady’s tresses on the lichen heath. Ragwort control was undertaken by volunteers around the shore of Ibsley Water, with virtually every plant removed. It is proposed that in future we continue with regular control close to the reserve boundaries but just to prevent it becoming over abundant elsewhere.

Once again six New Forest ponies grazed the grassland around Ibsley Water from July until November achieving the desired level of grazing. The late removal did cause problems however as it occurred after firework night and the animals were very agitated. It is intended to ensure that they are removed by mid-October in future to avoid this reoccurring. Work on the western and eastern shores of Ibsley Water continued with mowing to control ragwort, nettles and thistles and the removal of more willow and bramble to increase the extent and continuity of grassland for feeding waterfowl and nesting waders. The acquisition of a towed mower for the quad bike greatly increased the capacity to manage grassland areas.

7.3.4 Fen

Limited further work was done on the north shore of Ivy Lake to the west of Ivy North hide where a number of fallen willows were removed. Some of the area cleared between Goosander and Lapwing hides may also develop valuable drier fen communities in time.

7.3.5 Lichen heath

Small scale removal of invasive birch and bramble continued. The six experimental scrapes made last to investigate the impact of such work and potential to restore early stage heath habitat were monitored and it seems certain that these will need to be larger and deeper if the habitat is to be successfully “rebooted”. Assistance is being sought from local experts to identify the best areas to consider for this work.

Most insects benefited from the hot summer, although spring species had a rather protracted emergence, with many early records, but persistent cool, easterly winds prolonging spring conditions, which then switched, almost immediately into high summer. Odonata numbers were hard to determine, early species seemed, once again, genuinely scarce and many later species appeared in good numbers but seemed to have a shorter season than normal, probably due to the high temperatures. 10.4 Moth recording

As with Odonata several species appeared which do not get attracted to light traps. These moths are rapid, day-flying to have high peak numbers but shorter seasons than would be typical. species that mimic wasps and typically have larvae that mine under the bark of trees. A new species was recorded on the reserve in 2019, the The full data is available in the reports produced by Bob Taylor to whom orange-tailed clearwing, a species which mainly feeds on guilder-rose. thanks for organising the survey and producing the subsequent report is due. A summary of the data is to be found in appendix E.

One species was recorded as new to the reserve, although not on a transect visit, when a male chalkhill blue was found in the former Hanson plant site.

Total Sightings and Survey Average, taking number of surveys per year October; alternate am and pm surveys on each side. Different teams looked after into account: the am and the pm surveys and worked on different sides of the reserve in each survey week. AM – Jacki, Phil and Micky Total No of Average/Survey PM – Bob T, Judy and Adrian Adder Sightings Surveys Additions/modifications were made to a few survey locations for 2019, in particular 2014 41 7 5.86 new felts were put in the old Hanson Plant area and another moved to the entrance 2015 51 13 3.92 to the Millennium Meadow. 2016 55 16 3.44 Additional sightings, to those recorded on the formal surveys, were those seen by 2017 74 16 4.50 survey team members, reserve staff or knowledgeable visitors who had 2018 39 17 2.29 photographic evidence. 2019 80 17 4.71 Grass Snake 2014 13 7 1.86 2015 39 13 3.00 2016 68 16 4.25 2017 66 16 4.13 2018 54 17 3.18 2019 71 17 4.18 Slow Worm 2014 0 7 0.00 2015 1 13 0.08 2016 2 16 0.13 2017 7 16 0.44 2018 2 17 0.12 2019 3 17 0.18 For Adders and Grass Snakes sightings were closer to and slightly up on the totals and seasonal variation in 2017. The dramatic reduction in July onwards in 2018 was not apparent this year and may support the idea that the hot and dry period at that time in Adder by Garry Prescott 2018 had a bearing on sightings. 2019 did not experience the same prolonged periods of extreme heat and low rainfall. For Slow Worms the sightings were little different to 2018, although we were fortunate to see juveniles in 2019 confirming a breeding

c. Additional Sightings outside of the formal survey Newly hatched of each species were seen in 2019; those of adder and grass snake reflecting the biannual pattern seen in previous years. Juvenile adders and grass snakes There were a number of additional sightings of adders and grass snakes in 2019. of various ages, other than newly hatched, were also seen, and in a number of different Although the sightings were mainly in the usual places, they were incidental to other locations. Together the newly hatched and varying ages of juveniles indicated continuing activities and they were not necessarily within the time and weather parameters used breeding populations.
