Glow worms on the reserve

Thanks to the sharp eyes of the seven people who attended the annual glow worm walk this year we not only found 13 female glow worms (plus three on the roadside on the way home) but also a male. The latter find proving that being able to glow in the dark does work to attract a mate!

If you were unable to tear yourselves away from the tennis (or the pub) last Friday evening then there are still a few more weeks when a  walk on the reserve on a warm evening after dark should be rewarded with one or more sightings of a small green LED like lights.

In daylight warm sunny days should be rewarded with numerous Marbled Whites. Apparently the first Chalkhill Blues of the season and the second flight of Brown Argus butterflies have also been sighted. Gatekeeper butterflies were relatively numerous on the latest transect walk at the end of last week along with high numbers of Meadow Browns, Ringlets and a few Skippers. Whilst the orchid season is coming to an end there are many more flowers in bloom so  a trip to the reserve at anytime in July always has something to discover.

Note also the signs that ponies are going to be used for the first time this year to graze and help manage the reserve. This activity is essential to help maintain and potentially improve the biodiversity. Their heavier trampling of the vegetation and greater stress resistance to the presence of people and particularly dogs (although please do ensure you keep them on leads in the area where the ponies are loose) should help ensure the autumn management aims are successfully achieved.

June update from the reserve

Whilst the Man Orchids and Fragrant Orchids are now starting to fade the Pyramidal Orchids are coming into bloom and a couple of Bee Orchids have been reported so the display of Orchids continues and is supplemented by more and more other flowers coming into full bloom.

The warm weather has also brought out more butterflies with largish numbers of Meadow Browns, some Ringlets and Skippers seen on the recent transect along with the first Marbled Whites. Numbers still seem lower than previous years but at least they are now in double figures!!  The transect was walked accompanied by a seemingly rather late  but persistent calling cuckoo.

The walk was not quite the spectacle of close up encounters with Swallowtails on the Norfolk Broads earlier in the week but you do not have to travel far to get close to nature. A “well earned” cup of coffee in the garden was rewarded on Tuesday by a Red  Kite descending into the neighbour’s garden, ten feet from where I sat, to grab a frog based snack from the lawn.

Hopefully you will get the chance during the month to visit the reserve and get close to nature be it reptilian (common lizards are out and about), avian (yellow hammers and skylarks are singing above the reserve supplementing the cuckoo) or enjoying the flora that at least stays still once you locate it.

 

Glow Worm Walk 7th July 9:15pm

This year we will, weather permitting, be hosting the Glow Worm walk around the reserve on Friday 7th July. We are planning to meet at the main car park on Wittering Road at 9:15pm so we have a little time to acclimatise to the failing light before darkness descends. Please do wear sensible shoes as we will be walking across some rough terrain in the dark. A torch will also be useful at times to ensure safe navigation.

Please do let us know if you want to attend this event so we can plan for the numbers likely to be present and more importantly for you as the event is very weather dependent we can let you know if we decide to re-arrange probably to the following Friday.

I look forward to meeting many of you again for this annual event

Man Orchid Survey

A very big thank you to all those who came along yesterday morning and helped look for and count the Man Orchid’s present in the four monitoring plots. We found in total 66 flower spikes within the designated areas and approximately 20 just outside the various areas or during the walks between them. The number is about half the number seen last year and very similar to the counts made between 2007 and 2014. This may be accounted for by the particularly “lush vegetation” with the recent rain and warmth making it difficult to spot the flower spikes but we also have seen ups and downs in the population since the records began. We are well below the 1845 flower spikes recorded in 1985!

The weather was kind being dry and sunny without being too hot or humid. As well as the Fragrant Orchids coming into bloom and the odd Pasque flower hanging about the first Pyramidal Orchid was noted (I just managed to avoid sitting on it!)

A Brown Argus and a pair of Common Blue butterflies added to the sightings and what I hope was an enjoyable morning for all on this beautiful nature reserve.

The next event will be a guided Glow Worm walk in July please keep a look out on this website for details of time and date.

Last few days of May on the Reserve

Well a gloriously warm and sunny week at the end of May has certainly brought along the flora and the ground is starting to show lots of different species in flower including the first signs of Fragrant Orchids joining the Man Orchids.

The weather has also finally brought out the Green Hairstreak butterflies in significant numbers particularly on the Apple and Spindle trees along the path running parallel with the western boundary of the reserve in compartment 1 (South West quarter). Common Heath moths have also become numerous in the open grassland and a few Red Admirals have brought their bright colours.  Adding to these the general increase in moths, bees and  beetles,  with specifically a Longhorn moth – Nemophora degeerella and a Rosels-bush cricket nymphe (Thanks to Ian, visiting from Norfolk, for identifying these and providing the Green hairstreak photo)  the reserve really has come alive.

Unfortunately a downturn in the weather over the weekend and a traditionally wet Bank Holiday Monday has limited the enjoyment and opportunities to spot new arrivals. Hopefully if the weather turns dry as promised and the temperature stays up for next Saturday, the Man Orchid count should provide a great opportunity to add to this years sightings so please join us if you can.  

Man Orchid Monitoring Saturday 3rd June 10:00am

As reported last week the first flower spike of Man Orchid  has been spotted so we are now planning this year’s survey. With the support we have received for this event historically we are being ambitious this year and plan to survey the whole reserve (well the parts likely to support Man Orchids).

Your assistance with this task would be greatly appreciated but please note some of the survey will require walking up and down some significant slopes. We will try and match transects with people’s capabilities / wishes and of course we do allow you to deviate round very steep slopes and hawthorn bushes!

If you would like to participate in this event then we will be meeting at 10:00am in the main car park off Wittering Road. Weather and enthusiasm permitting we will cover at least compartments one and two (West end of the reserve) but you are welcome to join us when you can and for as long as you want. The area we can cover will be dependent upon how many volunteers we get so feel free to bring family and friends along. There is no charge for this event as it helps with the science.

There will hopefully be some experts present to answer any questions you have and for you to increase your general knowledge of the reserve and its resident species.

I look forward to meeting as many of you as possible on the day. If you can let me know you will be attending by e-mailing records@fbhh.org.uk that will help with the planning.

May on the Reserve

As the Pasque flowers loose their bright purple and yellow colours (final picture to remind us of this year’s display) and show off their “fluffy” seed heads an encouraging find was a small population of plants in the middle of Compartment 4 of the reserve. This is close to the area “scraped back to quarry rubble” in the early 2000’s so this hopefully bodes well for increasing the area across the reserve where these flowers are well established.  Circa 15 years after the major conservation work this area is starting to really show some interesting potential which shows how patient we have to be with some conservation efforts.

A walk across the reserve last week seemed like an update on’ Wind in the Willows’. A mole seemed to be taking a break from decorating and wandering across the reserve in search of ‘Ratty’. Quite a journey required to find a Water Vole near Barnack but Toad was seen later. Unfortunately out on one of his adventures he had come across an Adder and was not looking too good as the snake shot off into the undergrowth. This to my knowledge is the first reported sighting of an Adder on the reserve for several years.

Despite a few days of warmer weather the butterfly transects still fail to record any encouraging numbers of the early butterflies. A walk on a warmish and sunny Wednesday this week failed to reach double figures for either Orange Tips or Brimstones. A second Dingy Skipper of the season providing at least some encouragement to continue with the transect walks.

As the Pasque flowers finish their display and the Early Purple Orchids start to pass their best, the first Man Orchid flower spike has been found. With an extended warm spell of weather we should be seeing them (if we spend time looking for the green flowers in the green vegetation)  in reasonable numbers across compartments 1 and 2 in the next few weeks.

Peterborough Local Group of the Wildlife Trust Walk

A very big thank you to Sarah and family for providing a very informative and educational walk around the reserve this afternoon (Saturday 29th).

A Bank holiday weekend was unlikely to provide glorious sunshine and unfortunately this Saturday was no exception. So there were no Green Hairstreaks on display (in fact no butterflies at all). Just a single Green Carpet Moth representing this area of interest. 

The Pasque flowers, Cowslips and Early Purple Orchids delivered as usual and in some magnificent clusters. Supported by the identification of Early Spring Sedge and Rare Spring Sedge in close proximity, which allowed us novices to finally see the difference. Many other plants, just showing their leaves or first flowers, were pointed out to help us identify them later in the year. The walk also showed how, even on a relatively small reserve like this there are different areas supporting very different plant populations and the impact of management of the reserve.

The entomologists were able to catch and show us many insects the majority with names far to complex for me to recall or even attempt to remember. I do recall a very decorative Crane fly and St Mark’s flies of both genders ensuring the existence of the next generation. To help increase my knowledge of bees (a target area for me this year) Ashy Mining bees, Hawthorn mining bee, Common Carder bees and Nomad bees all but in a very visible performance.

The highlight for me was the first Glow Worm of the year spotted by a sharp eyed Mike without the aid of darkness and the characteristic glow which will come later in the year.

A dry day, some very knowledgeable experts, a wonderful group of interested visitors and of course a very special and almost unique reserve provided an ideal way to spend a Saturday afternoon.

Do keep an eye out for future events both on this reserve and other local sites and do come and join us. The next stars to appear should be the Man Orchids with Pyramidal and Fragrant Orchids close on their heels.

Plant Monitoring

With the Pasque flowers about at their peak and Cowslips still present in very healthy numbers right across the reserve, we are starting to plan the plant monitoring for 2017. The early purple orchids which have appeared in the last few weeks will soon be joined by Pyramidal Orchids, Fragrant Orchids, Bee Orchids, Frog Orchids, Twayblade, Common spotted Orchid, Spring Sedge and Knapweed Broomrape all of which have been recorded and monitored during the past 40 years. To maintain this database help is required, so please if you are interested in participating in any of these surveys do let us have your contact details. E-mail records@fbhh.org.uk and we will let you know how you can help.
