Mid-Week Special - Two Pines Fen, Frilford Heath Golf Course SSSI - 14, 21 and 28 November 2023

By -

On three successive Tuesdays in November, Abingdon Green Gym and friends (12 in total) completed the autumn cut and rake of Two Pines Fen, which is a calcareous (or alkaline) fen situated between the red and green courses of Frilford Heath Golf Course.  The cut and rake is to mimic the action of herbivores and allow light for seeds to germinate and prevent the build up of nutrients in the peat, as the calcareous fen specialist flora do not thrive in rich peat.  Because of its location, we can only visit it midweek as it involves either the closure of a hole or the moving of a tee to avoid the risk of volunteers being hit by a stray golf ball - and, judging by the number of balls we found whilst working on the fen, the risk of this would have been quite high!  We donned our hi-viz jackets and each day made our way from the compound car park along the track to the fen.  Luckily, we are hardy souls so we had all brought waterproofs for when it rained, but the joy of seeing the fen in the autumn sunshine was something to behold - that and finding lots of delicate wasp spider nests!

On 14 November, we concentrated our efforts on the red course side of the fen and, under Rod d'Ayala's guidance we cut and raked the reed and sedge and packed this into the ditch, which is acting as a drain for the fen.  We were careful to maintain the flow of water so that the whole area does not completely flood and use the natural shallow stream to achieve this.  It was great to see that shallow pools of water had formed as this will be a vital habitat for the larval stage of many invertebrates which, in turn, help pollinate the several species of orchid and other fen specialist flora that thrive here.  We did as much as we could on the day as progress had been hampered by a bit of rain - although we have known much worse!

The following week was the turn of the green course side, which tends to be much drier underfoot and is favoured by the stunning Grass of Parnassus (the county flower of Cumberland).  The green keepers had kindly put notices in the clubhouse to let the golfers know that the hole had been closed so we could work freely.

Knowing that we had not finished the red course side completely, we agreed with the Golf Club that we would return on 28 November.  Adrian did some mattocking out of willow scrub and after lunch, Rich started the cut of the rush in front of the ladies' 16th as one of the greenkeepers had told us that he had seen a butterwort in flower in the late spring/early summer, which is very encouraging as we think it is a new species for the site or one that has not been recorded for some time.  Susan came in the morning to help with the rake and then Jan came in the afternoon.  It was their first time of visiting the site.  Jan christened the two Scots pines in the middle of the fen, Duncan and Gordon, and found that it was quite comfy to sit against them after a hard spell of raking.

We need to return to finish the area around the 16th red tee which lies between Two Pines Fen and its big sister, Boundary House Fen, to provide greater connectivity and hopefully improve the chances for the fen flora and fauna to spread between the two, before we start the process all over again in the spring.

A huge thanks to Adrian, Eleanor, Jan, Jane, Jim, Kathy, Mike, Philip, Rich, Rod, Roger and Susan for all their help.

Pinkhill Meadow Nature Reserve, Farmoor Reservoir, 16th March 2019

Another week, another new site for the Abingdon Green Gym! We met at the car park at Farmoor Reservoir, a healthy turn out of 17 of us, including French father Sebastien, and his eleven-year old son, Maelo, who was joining us for a school project. The session was led by James under the instruction of Hanna Jenkins, the warden of Pinkhill Meadow Nature Reserve, so called because it is right on the banks of the River Thames, just near Pinkhill Lock. It was another blustery day. Will this crazy wind ever let up? We followed Hanna in convoy round the edge of the reservoir, which was choppy to say the least, and parked up on the other side where it was thankfully a little calmer, the high banks of the reservoir providing some shelter. Equipped with our tools, gloves and goggles, we made our way onto the spot on the nature reserve where we were to do our work. Hanna told us that the reserve had been formed in 1991, but some aspects had been neglected over the last ten years. The aim...

Kennington Memorial Field, 29th October 2016

By Andrew -
We have been working at Kennington Memorial Field for a number of years now, clearing scrub from the slopes so that the valley remains an area of grassland and wild flowers. This time Rachel from Oxford Preservation Trust was in charge and led us down to the lower end of the field, where we were to cut back the trees and bushes by several metres and burn the scrub on a bonfire. We were joined by some families with children of varying ages, the youngest only three, who had answered a local appeal for volunteers. We set to work and soon we had a bonfire going. Even the children who were too young to use loppers and saws joined in, carrying branches to the bonfire pile. Despite the drizzly weather they all worked cheerfully. At tea break time we enjoyed some delicious snacks that Rachel had brought and a tin of chocolates supplied by Michele. We found two old birds' nests in the course of the morning and cutting back the scrub revealed a log pile with a rabbit hole under...

Jarn Mound and Wild Garden, Boars Hill, 12th November 2016

Four weeks after our last session with the Oxford Preservation Trust at Boars Hill, we returned, albeit at Jarn Mound this time rather than the Elizabeth Daryush Garden; which had been our venue in October. We again met with  Rachel Sanderson of the trust, who along with our leader of the day, James, outlined the tasks for the morning.  Primarily, we were to clear the mound itself of scrub and tree saplings that had taken root there, with the intention of restoring it to its original state.  There were also some flatter areas of the garden that required clearing, for the less intrepid among us. Unfortunately, the day had begun a little on the inclement side.  Indeed as we arrived, the rain fell persisently, making many of us wonder if the session would go ahead at all!  But of course, the Green Gymmers are renowned for working whatever the weather, and the damp conditions did not deter us. A couple of problems were immediately evident due to the rain...
