You’ll probably hear skylarks long before you see them. In Spring and Summer, they’ll be advertising their territory with a spectacular flight display, rising high above the downs, singing constantly.
As a bird itself is relatively unspectacular, being a pretty drab brown streaky colour with 2 distinctive white stripes at the sides of a triangular tail. It also has a crest on its head which raises when the bird is alarmed.
Their song was once heard all over the English countryside, but in the past 30 years their numbers have fallen by oiver half. As is the story for most farmland birds. Modern farming methods have greatly reduced the areas where they can feed and build their nests on the ground.
Here on the Downs, as with most places they nest in medium-length grass, so please look where you’re putting your feet when off the path!
Spring, the season between winter and summer where temperatures gradually rise. It extends from the vernal equinox (day and night equal in length), March 20 or 21, to the summer solstice (year’s longest day), June 21 or 22.
In many cultures spring has been celebrated with rites and festivals revolving around its importance in food production. The concept of spring is associated with the sowing of crops. During this time of the year all plants, including cultivated ones, begin growth anew after the dormancy of winter. Animals are greatly affected, too; they come out of their winter dormancy or hibernation and begin their nesting and reproducing activities; birds migrate from warmer climes in response to the warmer temperatures.
The ecological definition of spring relates to biological indicators; the blossoming of a range of plant species or the activities of animals. It therefore varies according to the climate and according to the specific weather of a particular year.
Easter falls in this period and is categorised by the blooming of Daffodils. Of which are non-natives, believed to be escapees from private collections, but still nice to see this time of year. Here at the Downs we an Easter egg trail, which was so successful, with over 1000 children taking part.
The white blossoms of Hawthorn and Blackthorn also line hedgerows and roadsides, before trees come into leaf.
Bluebells are also a good indicator of spring, covering the floors of ancient woodland in a rich purple.
There are a number of events on the downs including a number of ranger led walks; spring flowers, orchids, butterfly and glow worm walks. Keep an eye on the NT website for the adverts and how to book.
It’s that time of year again and the spring lambs are being turned out onto pastures to fatten up for the season.
At Sundon Hills and Sharpenhoe Clappers the lambs have been put back onto the land following a successful lambing season by our tenant farmer. We ask dog walkers to please be respectful of this and to keep their dogs on leads.
The sheep at these sites act as a natural lawnmower, keeping the grass short which is part of a wider long term plan to un-enrich the land, removing the nutrients and inevitably reverting the land back to a florally rich chalk grassland habitat which is a nationally scarce habitat.
With a couple of hours free this afternoon I thought that I would take a wander around the Downs. If the truth was told I was butterfly twitching, hoping that I might see a very early Duke of Burgundy or possibly a Green Hairstreak. http://butterfly-conservation.org/679-1100/duke-of-burgundy.html and http://butterfly-conservation.org/679-1012/green-hairstreak.html
In the end I saw a Peacock and a Brimstone, too early for the others. Already in flower I saw cowslip, the food plant of the Duke of Burgundy, violets and blackthorn.
You might be able to see the leaves of a Common Spotted Orchid, there is a clearer one below. These orchids are one of eight species which can be found on the sunken trackways during the year.

The next thing that caught my eye was bright in the middle of the path – why do people do this?
Then I came across this plant and I was stumped which was a bit embarrassing as I used to a woodland manager.
Can you guess what the plant is, I didn’t until I saw a more developed one.
Quite a cute seedling.
I was heading back to the car now and wishing I had a birder with me. I had seen Red Kite, Buzzard, Kestrel, Blackbird, Wood Pigeon and lots that I couldn’t identify.
If you are near the downs over the next few days have a walk and see what is about, you might be the first person in Bedfordshire this year to see a Duke of Burgundy. If you feel like recording what you see you can do so on the Bedfordshire Natural History Society website – http://www.bnhs.org.uk/.

This winter one of our projects has been a Norman, 11th century Mott and Bailey ditch at Totternhoe. We have finally finished and the results are spectacular. Go to Totternhoe Knolls and see the results for yourself.……
A motte-and-bailey castle is a fortification with a wooden or stone keep situated on a raised earthwork called a motte, accompanied by an enclosed courtyard, or bailey, surrounded by a protective ditch and palisade.
Here we cleared out one of the ditches of scrub in order to improve the ever rapidly depleting rich chalk grassland habitat there is at Totternhoe and to protect and enhance the Scheduled Ancient Monument from disturbance.
It’s that time of year again – the end of the scrub bashing season. It has been a pretty intense but productive time of year. The main sections undertaken were the usual suspects – Totternhoe Knolls, Victoria Picnic Garden in Sundon, the 5 knolls (ancient burial mound), the sunken tracks near Whipsnade, roadside quarries at Moleskin and a new section by the wind catcher on Dunstable Downs.
What and how we do it…..
We use brush cutters, chainsaws and a BCS mower to remove ‘scrub’, which is basically anything that’s not a chalk grassland specialist. We then rake it up and burn it on designated burn sites.
Why we do it?
Chalk grassland is an important habitat for many species. Due to its dry low nutrient soil, many species are able to thrive here with little competition from other species. Up to 40 species of flowering plants can be found in one square metre of lowland calcareous grassland. This includes common flowers such as Scabious and Bird’s-Foot-Trefoil alongside many nationally rare plants such as Bee and Frog orchids. This rich wildflower habitat provides a home for many nationally scarce insects, including the Duke of Burgundy butterfly and Glow-Worms, both of which are unable to live on other habitats.
Current estimates suggest that up to 41,000 hectares of lowland calcareous grassland remain in the UK. The extent and quality of the UK’s chalk grassland is declining, mainly as a consequence of changes to land management and use. Traditionally chalk grasslands were managed by sheep grazing; by scrub bashing we essentially play the role of sheep which used to graze all of the downs.
Cutting and removing the scrub ensures the nutrient level in the soil remains low, allowing for the diverse variety of chalk grassland plants to keep on flowering year upon year.
The season runs from the beginning of October till the end of February.
It’s always a good day and we are always looking for more volunteers, so if you fancy joining us, especially over the winter give Austin a call on 07881848551.
Have to say a number of goodbyes. We are losing many of our number before this upcoming season……
The Visitor Engagement manager – Amy Green, been here for 14 months, is now off to NT Claydon – where she has landed herself a job as Visitor Experience/House Manager which is a live in position a Permanent Managers job in the house. Anyone in Bucks go visit Amy and Claydon.
Denise and Jon Summers – some of our most dedicated volunteers over the years (and my landlord and lady) is moving house to Dorset. Wish them all the best for the move to their perfect home by the sea. Hopefully will still volunteer with the Trust down there.
Stacey is leaving for maternity leave, good luck to her! But she will be back……….
Last but not least. Kimberly, our Seasonal Ranger for the last 9 months is off to bigger and better things, being a permanent job at the spectacular Hatfield forest.
We wish all of them the very best for the future. You will all be sorely missed.
