GET INVOLVED

We have a schedule of events for the year ahead. Join us on one of our practical days which offer the chance to learn new skills and get your hands dirty doing conservation tasks. Come and learn more about species in the park on our wildlife walks or become part of the Friends Committee which meets to discuss the functioning of the group.

FoSNCP hold a practical workday on the second and fourth Saturdays of the month and every Tuesday morning and/or afternoon to undertake conservation projects within the park.

At present we’re meeting at the council compound – the locked gates right by the tramline, on the vehicle access road at 10 AM. We usually finish around midday and enjoy a hot drink & biscuits.

Training and tools are provided. Please wear clothes suitable for outdoor activity and the weather, bring your own gloves if you have them.

We recommend sturdy footwear. Activities are subject to change at short notice.

If you would like to register to join us, please contact us by email – friendsofsncp@gmail.com. We can then let you know if we can offer you a space on one of the workdays.

WORKDAYS 2025

For previous years – see the archive!

11th January 2025

Our first workday of 2025 was very cold and frosty but beautiful blue skies made it a perfect winter’s day. Our task today was to clear away brambles and vegetation to uncover the primroses already beginning to show their heads. This lovely early spring display can be seen around the small woodland at the bottom of the mound. It’s a delicate process to ensure we don’t damage the primrose shoots when removing the brambles but important to let light into this area to aid their growth. The arisings were gathered up and added to the habitat bank which we created last year behind the woodland. Looking forward to seeing the fruits (or primroses) of our labour in a few weeks time.

 

25th January 2025

This Saturday’s workday and the previous Tuesday’s  (21st) concentrated on getting as much of the blackthorn cut back as possible in preparation for February’s hedge laying tasks. This winter, our reports have detailed the reasons for, and the location of, this conservation work. We have finally got to a stage where most of the planned clearance has been done. We have been processing the arisings so that we have material suitable for making a dead hedge. Some of the thicker blackthorn branches have been set aside for stakes which we will use to make the dead hedges.

8th February 2025

A damp and drizzly morning saw us make a short walk to our work site on the slope of the mound. This is an annual task for us to clear brambles to let in light and space to give the wildflowers a chance to flourish in the spring. The slope on the tram track side of the mound tends to get the most sun. Cowslips tend to dominate the area but other wildflowers such as primroses used to thrive in the sunny conditions. The primroses have all but disappeared these days so Ian’s plan is for us to plant some wildflower plugs in the future to try and bring back a variety. We filled ‘grab bags’ with the bramble arisings and dragged them back to the compound to add to the compost heap. A good morning’s work but we’ll need to return on another workday to finish it.

22nd February 2025

Our task today was to begin the creation of another ‘living hedge’ along the Seasonal Path (so called because the appearance of the path changes with the seasons). This was to be done by pleaching. Pleaching is a method of creating a hedge by cutting virtually through the trunk of a young tree & then laying the tree on its side so that it is horizontal. For this we used billhooks & saws. Ian showed us examples of previously pleached trees where we could see new growth had appeared as upright shoots from the horizontal trunk. Because the bark & cambium layers of each tree were to remain connected to the root system, the tree would continue to grow. Working from left to right each team of three had a 2-metre length of hedge to work with. First we needed to clear away any debris from the base of the hedge & then remove any dead wood & cut off any twigs growing outwards (they would injure the volunteers) or those growing directly to the left of the trunk (when the tree is bent over to the left, these would be facing directly into the ground & prevent the tree from lying flat). This gave us a clear view of what we were to work with. 
 
We were using what is called the ‘South of England Style’ of pleaching. Once the trees had been laid down, we added stakes. Once the structure is complete, long hazel binders will be woven along the top of the hedge, between the stakes. It takes time to build this type of hedge so the work will be continued on our Tuesday workday & by volunteers from The Conservation Volunteers when they come to the park next week.
 
One volunteer found a toad in the leaf litter, it was barely awake. We moved it to a safe spot to prevent it from being trampled.

8th March 2025

On the warmest day of the year so far, our volunteers were divided into two teams. One team continued work in Le Motes meadow, amongst the Blackthorn that had been previously cut. When the Blackthorn was cut, the arisings were left in large piles that needed to be re-sited to allow a corporate group to work cutting back more Blackthorn. This is a job that has been ongoing for a couple of months now and is nearly completed. As previously reported, without being cut back, the Blackthorn would encroach further into the meadow and we do need to control this habitat (we do not want to lose the meadow). Also, the young Blackthorn is the preferred food plant for the Brown Hairstreak caterpillars and we have found eggs on the young shoots. We’ve mentioned before that the Brown Hairstreak is classified as ‘vulnerable’ on the Red List for Great Britain. Nearby we can see some of the Blackthorn that was cut back 1 and 2 years ago, this has now regrown and reached a height of 1-2 metres.
 
We had the opportunity to admire our work and that of The Conservation Volunteers along the Seasonal Path. A living hedge is being created and we’ll continue working here on our Tuesday workday, when long binders will be woven through the stakes.

The other team had a much shorter walk from the compound to the environment garden and a small copse of hazel trees. We use hazel a lot in our nature reserve primarily for stakes and are currently using it in our hedge laying. Usually sourced from other Croydon sites such as King’s Wood, it’s an advantage if we can utilise what we have on site in SNCP. This small copse was previously coppiced some years ago and is now ready to be cut back again. We had to remove quite a lot of brambles to get to the copse but once in, we coppiced the hazel setting aside stems of about 5ft 6″ in height and a suitable thickness for stakes. These stakes will be used on Tuesday’s workday to help complete the hedge laying along the seasonal path. The rest of the brash from the coppiced branches was laid into neat habitat piles.

11th March 2025

Following on from Saturday’s workday, our smaller group of volunteers headed to the blackthorn copse next to La Motes meadow. A couple of volunteers used an axe to put points on the hazel stakes coppiced from the environment garden and then helped Ian to drive them into the ground where the hedge is being laid. Then a couple more volunteers weaved hazel binders between the stakes. Everyone took turns to continue the work of Saturday’s volunteers and make habitat piles with the brash from the coppiced blackthorn.

12th April 2025

Having split the volunteers into three groups, the biggest group, which was increased in size by the presence of members from Croydon Mountaineering Club https://thecmc.org.uk/, went to the path that runs along the tram tracks towards Harrington Road. The task was to cut back any overhanging or encroaching brambles to allow the tractor to pass along the path easily, so that the soft vegetation can be cut back. We were told that a large patch of brambles would be bi-passed by the tractor & the vegetation there would not be cut if the brambles prevented accessibility.
 
We finished our task a little early so that the Mountaineers could be shown the pool in The Wetlands, which they had helped to uncover last time they volunteered on site.
 
A smaller group of 5 volunteers headed over to one of the meadows running alongside Route 666 near the tram tracks on the Elmers End side. This meadow forms part of the butterfly transect route. Between April and September, we count butterflies on a weekly basis and submit the data to Butterfly Conservation. The path crosses a dip in the meadow which is gradually becoming overgrown with brambles hindering our route through. First making sure that there were no signs of birds nesting in the brambles, we then cut them back about 2 metres. Where possible, we dug out roots to prevent them growing back.
 
The last group of three volunteers remained at the compound to carry out some carpentry work. They made signs to put around the wetlands area advising park users that it’s a sensitive habitat for wading birds and encouraging dog owners to keep their dogs on a lead.

10th May 2025

A glorious day in SNCP for today’s workday. Our main task was to work along the narrow path which leads from ‘5 ways’ towards the reedbed beside the lake. This path is surrounded by a beautiful expanse of cow parsley at the moment which we want to retain. However, as the cow parsley grows, weather conditions can bend it over the path making it difficult to get through. Some of our volunteers used grass scythes to take the cow parsley back a short distance from the path. Amongst the cow parsley, there are a number of poplars standing proud which were planted a few years ago by London Wildlife Trust. The plan is to mulch around these to help retain moisture. In preparation, a couple of volunteers created a halo around the base of each one. See if you can spot the fluorescent jacket of one of our volunteers amongst the expanse of white. On our way back at midday, we picked up a small group of 3 volunteers who had been cutting overhanging branches from a path around the middle of our nature reserve. The tractor had started to cut alongside this path but couldn’t continue until we had cut back the branches in its way.

20th May 2025

Newly-planted trees in SNCP need a lot of after-care to allow them to thrive without being overwhelmed by scrub and weeds. In addition, our previous hot and dry summers have meant many volunteer hours watering them. To help, the Friends purchased a load of mulch which we distributed around young trees along the seasonal path as well as around the pleached stems where this year’s hedge has been laid. We were very grateful to a corporate group of young volunteers who had transported the many barrow loads of mulch to the site the previous week.

24th May 2025

The cemetery path is a narrow, winding path that runs alongside the stream adjacent to the cemetery from the Harrington Road entrance and coming out of the woodland near Elmers End Road. It isn’t one of the main paths although quite well used once discovered but does get very overgrown particularly with nettles. It also forms part of the Friends’ butterfly transect route so it’s important to maintain it. TCV were working in SNCP this week so they started work along the path and FoSNCP volunteers finished it off during today’s workday. We used a mixture of scythes and shears to clear about a metre of soft vegetation either side of the narrow path. Ian also used his brush cutter with two volunteers keeping a safe distance behind to rake away cuttings and warn him of any path users coming near.

14th June 2025

Our task this week was to carry on the work started by a corporate volunteer team which was led by The Conservation Volunteers. They had planted over 200 tiny trees in the “Friends’ Plantation” which is in the area near to the cemetery. Trees have been planted in this area over the last few years & the new additions, mainly Hazel, will be ready for coppicing in 7-10 years. The trees were supplied free of charge by The Woodland Trust and whilst we acknowledge that it’s not a good time of year to plant trees, we do want to increase the tree cover in this location.
 
During the week before our workday the Council tree surgeons had cut down some unsafe trees in the Elmers End area of the park. A large pile of bark chippings was created and it was this that we used during our workday. Firstly we made sure that every newly planted tree was marked with a cane, then we removed all vegetation in a halo around each tree. Lastly came the bark chippings, placed around each tree. This will act as weed suppression, moisture retention and will eventually rot down as compost.

28th June 2025

The middle of a heatwave is not the best time for a workday in SNCP but those newly-planted trees won’t survive without a bit of TLC and water. We headed towards the Friends’ Plantation  near the cemetery path – so-called by our warden, Ian, since we’ve been planting trees here over the last 10 years. The aim is to extend the woodland from the Elmers End corner with native species and it is really maturing and starting to be recognisable as a woodland. The most recent whips were planted by a corporate team of volunteers. Aftercare by FoSNCP volunteers involves clearing a ‘halo’ around the trees large enough to help prevent vegetation suffocating them. We’ve recently starting mulching around them too to lock in moisture and contain weeds. Lastly, and arguably the most important job given the current heat, is to water them. This is no mean feat given the water hogs need filling from the tap in the kiosk and then pulled to the site and poured into buckets and watering cans. No wonder one of our volunteers can be seen topping up her own water levels. Phew!

8th and 12th July 2025

After a small fire destroyed part of the fence and dead hedge near platform 4 at the lake, Tuesday’s workday involved repair work. Our volunteers did a brilliant job of erecting a new section of chestnut paling around this part of the lake. It’s important not to leave the reedbed exposed to anything that may get in and disturb or harm the wildlife.
The heatwave had returned for Saturday’s workday so finding some shade whilst working was a must. Just a small group today but enough to get started along the path between Ryelands field and SNCP. The vegetation either side of this path has recently been cut back by the Council to make it more accessible. However, some sections were left where overhanging branches barred the way. To make it clear for the next mow, we cut back overhanging branches using poles and then processed the cuttings making neat hibernacula or habitat piles well away from the path. Those volunteers making the hibernacula definitely had the better deal in terms of shade.

26th and 29th July 2025

Himalayan Balsam! At a glance, its pink and white flowers look rather pretty growing alongside the bulrushes in the wetlands. However, as pretty as it looks, it’s classed as a non native invasive species in the UK and landowners have a responsibility to remove it. It grows in damp areas alongside waterways which is exactly its location in our nature reserve. An annual plant whose seed pods explode showering seeds for metres. All these factors contribute to it overtaking the area it grows in if left uncontrolled and risking a monoculture of plant species. In addition, with its location alongside the stream in SNCP, the seeds can make their way further afield to other locations outside of our nature reserve.
Many volunteer hours are spent on clearing the Himalayan Balsam in the summer. TCV spent a day on it last week and our FoSNCP volunteers spent both Saturday and Tuesday mornings on the task. The shallow roots make it easy to pull out but, as you can see from the photos, there are many tiny plants to deal with as well as the tall flowering ones. It is hoped that, with regular clearance, we will one day eradicate it altogether from our site. Fingers crossed!
 

5th and 9th August 2025

The newly-installed platform 3 has been our focus for the last two workdays. Cutting back vegetation and overhanging branches from around the platform improves both sight lines and the general vista around the lake. Over the years since this platform fell into disrepair, it became more and more hidden from view. The added advantage of cutting back the vegetation is that it is now more visible from other viewpoints around the lake. There is still more work to be done but the view from platform 3 looking over to platforms 2 and 4 and vice versa are much improved. The cuttings were used to improve and build up an existing dead hedge along the path down to the platform. 

23rd August 2025

Ian was having a well-earned day off today but he’d left us clear instructions on what to do in his absence. Armed with pole saws, requisite hard hats and other tools for sawing and lopping branches, we headed for one of the paths not too far from the car park side. It made a nice change to have a shorter walk there and back than some of our recent workdays. As with many of the paths in our nature reserve, the Council contractors need easy uninhibited access to get their tractors down to mow the edges. Any large overhanging branches block their way so it was our job to remove them. Pole saws were needed to cut back the taller branches with some of us using loppers to cut these down into smaller pieces that rot down more quickly. Silky saws came in handy for those thicker but low hanging branches. 

3rd September 2025

On a drizzly Tuesday we carried on lopping overhanging tree branches to give access to the tractor to mow the path edges. Other Croydon Council such as the Cleansing Team also need access to empty all the bins.
We split the workday into a morning & an afternoon session, giving volunteers a choice.
 
It was a good opportunity to practice our tree identification – in this case Ash & Lime were being cut back. The arisings were cut into manageable pieces & used to create piles which will make refuges for insects. Cutting back the trees has allowed more light to fall on the ground, which may encourage growth of smaller species such as the wild rose already growing here.
 
We always stop to look at anything interesting that we spot during our work & in this case we watched the forest bug ore red-legged shield bug (Pentatoma rufipes) climbing the trunk of the Ash tree.

9th September 2025

On a lovely early autumn morning, we were tasked with uncovering the channel running through the wetlands. Some years ago, a pipe was installed to divert water from the Chaffinch Brook into the wetlands. A channel branching off in a couple of directions was dug to allow the water to flow into specific areas. Although we did a lot of clearing work in the wetlands last year, we didn’t get as far as the brook where the pipe enters. The channel has become quite blocked with fallen leaves and other soft vegetation. It was hard work clearing a foot or two either side of the channel but the results were rewarding. Still more work to be done in this area but a good start.

13th and 16th September 2025

Saturday 13th September and Tuesday 16th September
For both of these workdays, we started our annual tasks working in the reed bed at the corner of the lake near platform 4. This reed bed is the largest remaining around the lake and is a vital habitat for our wading birds. Just to demonstrate its importance as protection for nesting birds, we found an empty nest amongst the reeds once occupied by, we believe, one of the Warblers. Many years ago, willow was planted a little too close to the lake and, as a result, it encroaches on the reeds. We need to cut back the willow to prevent it overwhelming the reeds and losing this important habitat altogether. In preparation, we sharpened grass scythes so we could cut a narrow path through the reeds to get to the willow stools. We then used a mixture of loppers and silky saws to cut the willow down to the base. Our warden, Ian, then bundled up the willow cuttings which he intends to plant in another area of the nature reserve. Any vegetation we couldn’t reuse was added to the dead hedge around the lake.

27th September 2025

With 12 volunteers, Ian was able to split the group into two so that we could work on separate tasks. One group returned to the reed bed at the corner of the lake to continue work from Tuesday’s workday (photos included). We concentrated on removing willow and saplings from the area of reed bed closest to the platform. This is much easier to do while the lake is still low. A couple of our volunteers continued tying willow cuttings of different thicknesses into bundles for re-planting and low hedge making.
The other group worked in the woodland next to the cemetery path that we have been planting up over the last 10 years. After-care is essential whilst the newly-planted trees are maturing. Our volunteers cleared a halo around the trees to allow light in and prevent soft vegetation from taking over. The Council tree surgeons had left piles of wood chip for us to use after they felled dead or dangerous trees around the park. We spread the wood chip around the base of the trees to suppress weeds and lock in moisture.

11th October 2025

As Ian was on annual leave, he left us instructions to carry out tasks along the path that runs next to Ryeland’s Field. This path is not only regularly used by park visitors but Council vehicles need to get through for mowing or emptying bins. Overhanging branches can inhibit these activities so Ian needed us to do some crown raising of the trees along the path. This involves using pole saws to cut back the lower branches to the trunk to lift the height of the tree canopy. In Ian’s absence, it was up to Sundeep to demonstrate to volunteers the use of the pole saw and how to make undercuts to minimise the risk of splitting the branches. The sawn branches were then cut up into smaller pieces and made into habitat piles to provide shelter and food for invertebrates and other smaller wildlife.

18th October 2025

With Ian still on annual leave, he’d left us instructions again for which tasks to complete. A short walk from the compound is a path just before the entrance to the car park. This path is part of the route for our butterfly transect. Sadly, it’s also a bit of a hotspot for fly-tipping. At the other end of the path is another one running behind the compound. Both these paths had become a bit overgrown with soft vegetation and overhanging branches. We split into two groups and set to work to cut back anything that was obstructing the paths as well as clearing as much rubbish as we could. We added the arisings to a habitat bank we had previously created as well as making a new one for the rest.
 

25th October 2025

Last year, a lot of work was done to clear the pool in the wetlands of yellow flag iris. A beautiful plant when in flower, it is a good habitat for insects but can be invasive if left uncontrolled. Although the yellow flag iris in the pond is now under control, some annual clearing needs to be done to keep it this way. Waders were needed for this task as well as good balance when pulling out the plant if we didn’t want to take an unexpected plunge! We concentrated on pulling the iris from the section visible from the path so park users have a good view of the wildlife on the pond. We then dragged the iris across the water and pulled it onto the bank to rot down.

4th November 2025

We had enough volunteers to manage two tasks today. Those who were happy to work in the wetlands pond, put on their waders to do some more work to clear flag irises and bulrushes. The aim was to expose a larger area of surface water for the benefit of the wading birds and other wildlife that use this pond. Some of the vegetation can be pulled out with ease but sometimes spades are needed to dig it out. The arisings are then pulled out of the pond and put into a pile to rot down.
The second task was on dry land a bit further along the path from the pond. Overhanging branches needed to be cut back to make it easier for park users to access the path. The arisings were added to the dead hedge between the path and the wetlands area.

8th November 2025

Today’s workday was a continuation of the tasks we did on Tuesday. In the wetlands pond, we managed to expose an even larger area of the surface water. An added bonus was hearing the call of the Water Rail from its hiding place amongst the vegetation at the edge of the pond. It sounds like a piglet squealing and, being a shy bird, you are more likely to hear it than see it. 
The rest of our team did a bit more work to cut back the overhanging branches from the wetlands path.
 

11th November 2025

For the morning task, we headed all the way over to the Elmers End side of the park to platform 1. Ian wanted us to help him improve the sight lines from the platform which involved cutting back overhanging branches and soft vegetation from the edge of the lake. Some of us needed to wear waders and get into the lake to do this which attracted some curiosity from our feathered friends. Those volunteers who prefer to stay on dry land cleared vegetation from the sides leading up to the platform. We made a dead hedge with the arisings partly to provide a temporary barrier until Ian is able to repair the broken fence at the edge of the lake. We need to make sure we provide as much protection as possible for our wildlife making it as difficult as possible for unwanted visitors to access the lake.
 
The other task that we carried out was to place bark chippings around the base of the log walls which are sited along the path, near to the reed bed.
The Council tree surgeons had left a pile of bark chippings at the entrance to the Seasonal Path when dangerous & dead trees were felled earlier in the year. These were shovelled into wheelbarrows & taken to the log walls where they were spread around the wall bases.
As the bark chippings will rot down quickly, we hope that this will encourage invertebrates, fungi & even stag beetles, to use these walls. In fact we already found several fungi in the bark & on the wall so we know it’ll work.

Tuesday 18th November 2025

We’re back working amongst the blackthorn behind the laid hedge along the seasonal path. This is part of our ongoing project to improve the habitat of the Brown Hairstreak butterfly. This elusive butterfly has been in decline in the UK in recent years. The Brown Hairstreak lays its eggs on young blackthorn and conservationists are encouraging the practice of cutting blackthorn hedges on a rotational basis every few years rather than cutting them every year. This gives the female time to continue its cycle to encourage more eggs to survive. Ian has divided the blackthorn into roughly three compartments, each one being cut every three to four years. He surveyed the new growth for eggs and found 60 which is very encouraging. 

 

22nd November 2025

One of our tasks today was to continue cutting back the older Blackthorn as we did on 18th November to encourage the female to lay eggs on the young growth. We had the opportunity to look at the Brown Hairstreak eggs through a magnifying loupe & we all agreed that they really do resemble a sea urchin shell. Many branches where the eggs had been spotted are now marked with red & white hazard tape so that we don’t inadvertently cut down those branches.
 
The other task was to retrieve the the lifebuoy & lifebuoy holder from the lake using a grappling hook & fix it back to the top rail on Platform 2. Sadly anti-social behaviour continues to be a problem in our nature reserve.

13th December 2025

For today’s workday, we began work on this year’s section of blackthorn next to La Motes meadow. As explained in previous workday reports, we are coppicing the blackthorn here in sections on a 3/4 year rotational cycle. The aim is to improve the habitat for the Brown Hairstreak butterfly. Ian has surveyed the young blackthorn for eggs here and in other sections of the park. So far, he has counted almost 300 eggs and marked the stems with tape so we know not to coppice these. They are mostly found along the outer blackthorn bushes and are easier to find in the winter once the leaves have fallen. Blackthorn cuttings take a lot of processing because of the spiky branches. Once this has been done we can make habitat piles or add them to the dead hedge we made behind the laid hedge.

16th December 2025

Our last workday for 2025 involved tree planting. We have been given native Hazel and Hornbeam whips by CPRE London. Ian’s plan is to create coppices which will eventually provide material for us to use around SNCP for laying hedges and making fences. The location of the coppices is alongside Ryelands field. Ian demonstrated how to prepare the hole for the whip, plant it, support it with a thin stake and protect it from nibbling voles with a small tube. The whip will grow into a tree over the next 7 – 10 years before being coppiced. This involves cutting the tree down to its base (stool) which will then re-grow and produce many stems from the stool which can be used for stakes and binders. This process of coppicing will continue on a rotational basis every few years. Today was just the start of the tree planting which will continue throughout the winter.
