Hilgay & Methwold Wetland Developments

Nick Carter, Conservation officer (Fens)

I have been letting water into the Hilgay lagoon and have so far reached 1m above sea level, with a further 0.59m to go to maximum capacity. I have to hold this level for one month and check the lagoon banks to ensure they are stable and there are no signs of leaks or erosion. 

On Wednesday Elliott Corke from Hexcam came out to take the next round of aerial photos using his drone and they show the works at Methwold from a new perspective and also how wet the Hilgay site is now that we have been abstracting water into the lagoon and into the perimeter and internal ditch network. 

The eastern end of the site i
s the lowest part and is consequently very wet. The main aims over the next couple of months will be to try to get the lagoon water level up to 1.59m above sea level and to fill the internal ditches. This will enable us to graze the site more easily to keep the vegetation under control.

Barn owl mitigation

Nick Carter, Conservation officer (Fens)

Next year's excavation works at Methwold wetland creation site will get close to the existing barn owl box on the site and so we decided to cap the box this winter and install a new box to ensure no disturbance for any breeding owls.  

Colin Shawyer, of Wildlife Conservation Partnership, visited the site this
week to carry out the work and also to move an unused kestrel box and
re-position it in a better location.

 The site’s female barn owl was roosting in the box. After checking, when she turned out to be very healthy 385g, she was released and flew to a nearby treeline, which was where the new box was erected.

Checking her ring confirmed that she was four years old. Colin moved the old kestrel box from the nearby wood and placed it along the same treeline as the barn owl box. Hopefully both boxes will be used next year.

Training day for livestock-checking volunteers

This week I was pleased to have the opportunity to join some of our livestock-checking volunteers on a training day in West Norfolk. The day started at Grimston Village Hall with a quick introduction, then we headed to NWT Roydon Common, where some of the resident semi-wild Dartmoor ponies had been earlier corralled to an enclosure so we could take a closer look. As our volunteer checkers will tell you, this was an essential bit of preparation as it can sometimes take several hours to find the ponies when they are roaming freely about the reserve. Malcolm and Sally Bruce are part of the Roydon volunteer team, they check Roydon together, they split up and it can still take 2 – 3 hours to find all the ponies and check that each one is okay.

We split into two groups, then the NWT Grazing Manager, David Tallentire explained more about the ponies: how they were managed on site; and what to look for when checking livestock, including carrying out condition scoring which is a way to assess pony health. The Dartmoors were showing a healthy weight, which is what we would expect at the end of a good summer. As we head into winter and conditions get more harsh they will need to use these fat reserves. The assistant warden at Roydon, Lizzie Bruce then gave a tour of the common, explaining the many projects taking place at the moment, and we were able to see the results of previous restoration work that has taken place.

The ponies are an important part of this restoration work. The heaths and mires on the common have been formed by hundreds of years of traditional farming with cattle, ponies and sheep, by chomping through the yearly vegetation growth; the ponies continue this grazing and maintain these high value habitats.

Many reserves benefit from NWT livestock grazing, which includes Dartmoor ponies, Konik ponies, British white cattle and our flying flock of Shetland sheep. Our livestock needs to be checked seven days a week, and our volunteer checkers are an essential support for this. All our animals are semi-wild so the checkers do not touch them but perform a visual check and note anything that doesn’t seem right; they can then report to the warden any observations, and if necessary a vet can be called. They are also an important help with vet and farrier days. Last year over 1,800 hours were donated by our volunteers checking our livestock, and we are very grateful for all their support.

The training day continued after lunch with a slideshow about how livestock is utilised on our different reserves, explaining the reasoning behind conservation grazing and the uses of different types of livestock. Then a trip to NWT East Winch Common to see our new herd of British white cattle (a traditional English breed with a long history in Norfolk) and to learn more about NWT grazing plans for the future.

It was a very interesting day and it was a good opportunity to meet some of our super volunteers and learn more about their volunteering experience, and put faces to the volunteers with whom I usually only have email contact. The feedback from the volunteers who attended agreed that it had been an interesting and informative day, and they also found the day useful to meet staff and other volunteers.
