A rescued Pear tree on SRW

FOBH Tree Warden, Roger Miles, has spent years tending Bernards Heath and the Sandridge Road Wastes (SRW), including a multi-year effort to rescue a pear tree. Before 2017, he spotted an ornamental pear on the eastern side of the SRW which was growing at a jaunty angle.

His careful work over the last seven years has resulted in a vigorous and upright tree which is now a credit to the area.

Our thanks to Roger for his continuous, and often under noticed, work conserving our local flora.

Work starts to refurbish the playground on the Heath

“It is happening at last! The playground is closed for work to begin on its refurbishment.

The target of £100,000 is now just a whisker away, a fantastic effort by the whole community!

With the refurbishment underway, the new playground will be ready in January, well before the Spring deadline. 

Let’s Play at Bernards Heath would like to thank all those who have donated to help make this dream a reality.”

What a Bind

Invasive bindweed on the Heath


You’ve probably noticed that a plant with attractive trumpet shaped white flowers (see photo left) inhabits many parts of the Heath. It appears between spring and autumn and is called hedge bindweed, or just bindweed and it has a habit of choking other plants by winding around their branches. There is also a smaller form, commonly called convolvulus with white or pink flowers.

These plants can become a menace because they have long root systems not easily removed. They can be controlled by commercial weedkillers containing glyphosate . Bindweed is now well entrenched on many parts of the Heath.

If you have a garden, it is advisable to treat affected areas as soon as possible. Japanese knotweed can also take over areas of ground and we have successfully treated an outbreak.


It’s what FoBH are for

Earlier this year Heath Field gained another piece of furniture; a bench seat in memory of Marian Wright. This has been installed beside the cycle path, filling a space where two trees had successively succumbed to vandalism.

Being made from quite substantial oak timbers the seat should be immune to damage, but instead, a potential hazard was noted, to small children in particular. The two attachment bolts for the backrest, see below were over-long and stuck out where a child’s head or face could have made contact, with unpleasant results. The seat should not have left the factory in that state.

We pointed the possible danger out to SADC Green Spaces, but as nothing had been done the FoBH fixer was deployed, with the improvement that can be seen in the photos.

A similar seat on the other side of Harpenden Road has bolts concealed in the wood.

Ground Survey of the Lower Field by GBG Geotechnics

Following the emergence of a depression or ‘hole’ not far from the centre of the Lower Field in late November 2019, Hertfordshire County Council commissioned a geophysical survey of the Field by GBG Geotechnics, Cambridge. A lengthy quite technical report on the survey was made available to FoBH and here we try to summarise its findings.

The hole was promptly surrounded by safety fencing and soon after by more fencing. The appearance of yet more fenced off areas last year led to some concern whether the whole field would be excluded to the public. We have no indication that this might be the case.

Storm Ciara takes its Toll

This large tree fell on a path during Storm Ciara on Sunday, February 9th. The path is the second on the right after entering Spinney Lane (see arrow on map alongside) and it is blocking the path, unless you are really determined to get through!  Now cleared! It was on the big side for the Friends to clear, so the Council has been informed. No doubt they have plenty of debris to clear – hopefully they will be able to get to it soon.

More substantial trees have since fallen as shown below:

New Depression appears on the Lower Field

The depression in closeup is about 2 m wide and 0.5 m deep.

This small depression has appeared on the Lower Field and has been cordoned off. The Fontmell Close sinkhole was probably only 200 m away, although in this case it may be a consequence of the rubbish that was buried in the area.

The field was surveyed in detail in 2015 since it is in the area covered by old clay pits and was the site of a rubbish tip. The company Carter Jonas was involved in the survey and is now in the process of reviewing the ground condition reports for the site.

Repair of Vandalised Bench

This bench, which faces Heath Farm Lane, was badly damaged by an attempt to burn it. Now RM, with help from some pupils at Sandringham School, has done an excellent job of repairing it. The wood is English oak, which is very expensive – it fact it would cost several hundred pounds to make a bench like this, not counting labour.

Unfortunately, there have recently been other incidents of senseless vandalism. Attempts to burn other benches and rubbish bins as well as spray painting – it only spoils the Heath for the majority of users.
