SCRUB ETC REMOVAL ON BULLS CROSS

Bulls Cross is one part of a SSSI comprising Bulls Cross, Juniper Hill and the Frith, located within the very large Cotswold Commons and Beechwoods NNR.   The woodland makeup, is dominated by ash, includes yew and a shrub layer of hazel and hawthorn. See GVCV task report of 29/01/2017 for a fuller description of the site.

Our task on 14 January 2018 was to continue the scrub etc clearance in order to encourage the reversion of the area to limestone grassland. The grassed areas on the site are serving their original purpose since cattle were re-introduced onto the land (summer grazing only) in 2013. The plan being followed by Natural England, the managers of the site, is to complete work on the partly cleared strip of land adjacent to the A4070 before venturing into the Ash woodland on the North West side of the site.

The problem with Ash as ever is their profligacy, each tree dropping thousands of seeds, a large percentage of which take root. These seedlings need to be removed by a determined attack to prevent them reaching a size where they in turn drop seeds and exacerbate the problem. This is generally done by cutting off at ground level and treating the stumps with herbicide to kill the root below. An innovation is the use of “tree poppers” which enable small seedlings to be ripped from the soil, roots and all. Of course a small amount of exertion is needed to use these tools – who ever said conservation was easy !.

The tree popper in use

Movement around this part of the site is problematic because the ground levels vary greatly. The site is transverse by an ancient drove road (hence the name Bulls Cross) which over time has become a cutting with raised banks both sides. There are small borrow pits where stone has been extracted for domestic use and also raised areas where spoil has been tipped including quantities of ash. There are now also quantities of dung, kindly left for us by the cattle grazing earlier in the year, so changing footwear before getting back in the car is a definite necessity.

Taking out isolated seedlings produces no dramatic change to the view so it is only by watching the great heaps of brash going on to the bonfire that the results of our labours can be appreciated.

The results of a whole day’s effort, gone in a puff of smoke

Much of the work undertaken on this site is to improve it as an environment for the rare Duke of Burgundy fritillary which has been seen on adjacent sites. Natural England’s ambition is to create a favourable environment along a continuous string of locations so as to create a “butterfly highway” to facilitate migration and propagation.

I do like to see a volunteer happy in their work

Another visit to Aldwick Wood Kemerton to try and remove the rest of the fencing from the site. A good turn out of 5 volunteers and weather generally dry with a few odd showers. A brilliant effort from all to nearly complete the task, the remaining fence was mostly amongst thick bramble or covered in soil. That should be our last task  on this fence.

A welcome return to the farm at Ruskin Mill for a spot of hedgelaying. Continuing with the same hedge with a lot more hazel and less thorn than last time. Three of us attended and we were joined by a few volunteers at Ruskin. Successful days work and very pleased with what we achieved. Hopefully to return in Jan/Feb 2018.

A welcome return to this grassland site on the outskirts of Dursley, managed by the Stinchcombe Hill Trust.

Overlooking Dursley, 6 of us, along with 3 Stinchcombe Hill volunteers, helped the site manager cut back encroaching dogwood, wayfaring tree along with beech saplings. This was on a stretch of wildflower rich grassland that is habitat for many butterfly species as well as other invertebrates including some rare moths and beetles.

A good day’s work which ended in bright sunshine.

Ongoing restoration of the Thames & Severn canal (summit section) at Coates

The restoration of this section of the canal by the Cotswold Canal Trust is much delayed by the need to raise substantial finance to repair the Sapperton Tunnel, which has collapsed in a number of places, one collapse completely blocking the canal

Southern portal of the Sapperton tunnel at Coates.

In the meantime the Trust are making all efforts to stop further degrading of the canal and to improve its current state wherever possible. In terms of what is feasable by small groups of volunteers this means keeping the bed of the canal clear by strimming, similarly clearing the earth banks of the canal including removing small trees etc whose roots are applying pressure to the canal walls, and maintaining the towpath which is well used by walkers. All of these ongoing tasks GVCV have assisted with a number of times.

The good news is that we have almost caught up with works needed after many years of neglect in terms of the canal bed and the South bank. This level of restoration now just needs to be maintained. The next target however is the North bank, which has been untouched for many a long year and which contains a number of significant trees to be removed. It’s good to have a challenge to look forward to.

Our task on Sunday was the continuation of the works in the canal bed and on the South bank. The adventure element here was that the bank is very steep, ending in a vertical drop into the canal, so the work was carried out swinging on a harness attached to a rope anchored to a convenient tree further up the bank. Strimming is a strenuous task at the best of times but combined with acrobatics it is a VERY strenuous task. Fortunately the site warden has been doing this for a number of years and is particular about the necessary safety precautions but to beginners like us it certainly resulted in a raised pulse rate.

TREE POPPERING AND GRASS SEED COLLECTION AT RUDGE HILL COMMON

Cotswold Commons and Beechwoods NNR is the largest nature reserve in the Cotswolds. It is largely made up of a chain of beechwoods and limestone grasslands around the upper slopes of the Painswick Valley, in Gloucestershire. The NNR includes Rudge Hill common, formerly named Edge Common. Its status as a SSSI is under the name of Edge Common. The area of Rudge Hill is 0.3 hectares or 0.74 acres, a relatively small portion of the whole reserve.

The main habitats are woodland and limestone grassland. The grasslands of the commons feature a rich limestone flora which support a variety of insects, particularly butterflies. These include chalkhill blue, Adonis blue, small blue, dingy skipper, green hairstreak and, at Rudge Hill Common, the rare Duke of Burgundy fritillary.

The Cotswold Way passes through Edge Common.

It is an unfortunate fact that the Ash tree is far too fertile for our liking and drops large numbers of seeds, many of which take root and grow and threaten to overwhelm the balance of the woodland on the site. Removing these by digging out is very disruptive but some clever chap has developed a “tree popper”. This is basically a long steel lever with jaws at the end which are used to grip the sapling at low level and then remove the sapling complete with its root causing minimal disturbance of the ground. Great exercise for the biceps.

The popper tool in action

On a nearby site, Bulls Cross, Natural England are preparing to install a small herd of cattle to graze throughout the summer. There is a concern that the existing grass might not be sufficient to sustain the cattle so grass seed is being harvested from other sites, including Rudge Hill, to be overseeded at Bulls Cross. The clever trick is that the grass seed will be scattered immediately before the cattle arrive so that they will trample it into the ground and there will be no loss to birds. Collecting grass seed is certainly a lot more restful than most of the tasks we tackle.

The warden doing her fair share of the work

GVCV have carried out clearance work on the Coates site a number of times in the past but, you know what, the darned stuff keeps on growing so we have to keep returning to it.   Basically we are keeping the existing structure of the canal in as good a state of repair as we can pending commencement of serious restoration works.

We joined members of the standing canal maintenance team and our main objective on the day was to clear as much of the canal bed as possible of rank grass and low shrubs,   Secondary task was to clear the margins of the tow path to allow easy access by the large number of walkers who use that area on a weekend.

The bulk of the work was done using brush cutters, the only practical tool for the job.   One of our number plus the Warden are qualified users by virtue of attending a formal course and by cascading our knowledge down we managed to increase the  number of volunteers actively attacking the canal to five.   This allowed us to clear a substantial area and provided much appreciated entertainment for the walkers passing by.

I’m sure that our newly initiated machine operatives are proud that they have added another skill to their conservation CV and I hope that a hot bath that evening relieved the unaccustomed strain which the machines put on back and sides.

On a windy and sometimes showery day four keen volunteers set to removing an old fence from in the wood. The aim is for the estate to be able to erect a larger deer-proof fence to enable Ash regeneration without them being nibbled. The hope is that at least some of the Ash will be able to survive Ash die-back.

Quite a hard task to undertake, with some of the fence engulfed in undergrowth, however, we managed to clear nearly half the fence.

Kemerton Conservation Trust is a forward thinking organisation involved in both commercial farming alongside conservation of the landscape and it’s wildlife.

We hope to return to complete the task at the end of July,

On Sunday three of us ventured out into the wilds of backwater Gloucester. Alney island is a small, mainly grassland, reserve on the outskirts of the City flanked on either side by the River Severn and acts as a flood plain. It was quite a windy day so we weren’t so lucky in seeing many butterflies (Green-veined White, Orange Tip,  Large White, Speckled Wood, Red Admiral and Tortoiseshell) but enjoyed the varied habitats and plants. We also walked over Telford’s Bridge and across to Over Wharf to look at the small stretch of Hereford and Gloucester Canal. On our way round we saw some of the Gloucester cattle that graze the site (along with some longhorns at times) and heard a Cuckoo near to the Electricity sub station. We also paid a visit to the Docks for a bite to eat.

In all a wonderful area of open space that deserves to be visited.

With six volunteers we continued our work on the main path by adding more chippings where it had become a bit muddy, also further on by another entrance to the reserve. We also cut back some bramble encroaching near to path and bramble/clematis from some grass scallops near to the pond, hopefully to give plants a bit more room and prevent them being swamped by the clematis in particular (although we were careful not to lose all of this and the bramble as good nectar/ food sources for insects).

Another task was to start coppicing some of the overgrown hazel to give a new lease of life.

Whilst there we spotted Brimstone and Peacock butterflies as well as fish in the pond and possibly frogs although difficult to see these clearly.
