Volunteer Group Diary




5 December 2019

There was more tree planting, more fallen branches for the fire, more bramble removal covering the old wall and a wash down of the gale stone!


Two Tulip trees were planted


Our usual monthly day at the Arboretum was enhanced with our end of year fish and chips which was very much appreciated!


Every time we go to the Arboretum the fences are checked and we go round the perimeter litter picking.



Centenary tree planting - 21 November 2019

Today, we celebrated 100 years since the formation of the Forestry Commission to restore the nation's woods and forests following the First World War, and the passing of the Forestry Act.

We planted 3 trees

A Black Poplar tree with a commemorative plaque donated by Anthony Hart, the son of Cyril Hart, was planted to thank the Dean Green Team for their volunteering work over many years at the Arboretum.

The Jubilee Oak, which had been planted in 2002 had been decimated by squirrels so it was decided to replace it with a Tulip Tree.

A Hazel tree was planted by the Forest Verderers for the 100 year centenary


Many of the Dean Green Team and the Rangers attended the plantings



7 November 2019

It was an absolute glorious autumn day at the Arboretum today so quite a few of the team joined us. We did our usual job of collecting fallen branches and pulling out brambles plus their roots. We did have a couple of rangers with us who were strimming bramble and nettles around the large trees which was a bonus for us!




3 October 2019

We collected up a mass of branches from another fallen tree for the fire. We have got a load of new tree labels to attach to the trees and the image below shows the problem of finding the appropriate tree on the maps!


We found this rather fat toad hidden next to the tree when we were pulling out the bracken so we re-homed him amongst some logs.





5 September 2019

A good day at the Arboretum with plenty of tree branches to burn on the fire. Trees are only felled if they are diseased or could cause a danger to the public. As usual, there were plenty of people walking through the Arboretum and many of them brought their dogs. We did the monthly litter picking which is not onerous but essential.






8 August 2019

A lovely summer day to do various jobs in the Arboretum. Fallen branches were removed from the site and taken in the FC truck out into the forest, our old fire sites were scraped to remove the ashes, litter picking was done around the site

The photo below shows the removal of masses of over hanging branches which were smothering a small Acer.




16 July 2019

We usually work at the Arboretum on the first Thursday in the month but we were asked to come back today as a massive branch had fallen off a large Oak tree. It was too hot and dry for us to burn the debris so we used an FC truck to transport it all out into the nearby forest. There was also a large pile of old branches to clear from the previous trees which had been felled due to disease. See our Diary page HERE




4 July 2019

There were three very large trees cut down today. One was a Norway Spruce and the other two were Pines. The base of one of the trees was totally rotted and could have been a hazard if it had fallen by itself. It had squirrel damage in the top of the tree and that is why we had been monitoring it. We are unsure what had caused it to decay as it may be age, ground conditions, possibly a fungus but there were no signs of any fruiting bodies etc. in the autumn.

There was also a Crab Apple tree which was smothered in ivy and had many dead branches. We cut the ivy and dead branches off with the hope that the remaining greenery on the tree will revive it.




6 June 2019

We had a number of jobs to do today including weeding the hedge which we had planted nearly 5 years ago. It's doing really well but needs attention from time to time. Some of the tree enclosures were weeded - another ongoing job. The Acer grove at the back of the Arboretum needed staking but is looking very good. The sundial also had it's annual coat of linseed oil.

This is the Bigleaf Magnolia which has come into flower for the first time and has huge leaves that are 12 to 36 inches long, and ivory-colored flowers that average 8 to 10 inches across.




2 May 2019

A fine, if a bit chilly, day at the Arboretum with general tidying up going on. We cleared up the fallen branches from the trees which fell in a gale the previous week. The Bluebells were still around and we pulled up loads of brambles which were just starting to really sprout.


Can you find this majestic tree in the Arboretum?





4 April 2019

Well... unbelievably... there was a snow blizzard covering the whole of the forest which deposited about an inch of snow everywhere. Did this put our stalwart team off from working at the Arboretum? Not at all! - a few hardy souls arrived and the impetus was to get a good fire going from the branches of a felled tree. Repairs to one of the compounds were made.





7 March 2019

There were a couple of very large trees which had been taken down due to disease so we spent the day cutting and burning them. Spring is on the way and the early blooming Rhododendrons are flowering.





7 February 2019

The team taking a break on a day where we had sunshine but a fierce, cold wind. We tidied up the enclosure of the ancient yew, cleaned the green algae off the Cyril Hart stone, and collected and burnt all the fallen branches. We also had to take down one of the old benches as it had rotted at its base and become wobbly.





10 January 2019

This enormous tree had blown over in the last few weeks. It was our job the clear up and burn all the branches which took us all day. The cut logs were also reduced to a reasonable size for those of us to take home for wood burning fires which is one of the perks of volunteering with the Dean Green Team!



A few of the team perched on the fallen tree at the start of the day.
