Hempstead Meadow - Pulling the Balsam.

A couple of years ago, I spent a couple of mornings pulling Himalayan Balsam from the Hempstead Meadow nature reserve, run by Uckfield Town Council.  I thought we had done a pretty thorough job until the next time I travelled by train and saw a band of pink at the far side of the reserve. At the time, it felt like it was taunting me.

Himalayan Balsam - pretty but invasive.
You know what they say about revenge? It's a dish best served cold. Today I, another volunteer and the Town Ranger, removed significant quantities of Balsam from two good sized areas of the reserve.  I was particularly pleased that I created spaces for seed from the pretty, frothy Meadowsweet to fall into.

I knew that the Black Poplars (see back left of photo) that grow in the reserve are rare and special but I didn't know that they were such tricky breeders. Our knowledgeable ranger, Geoff, explained need a male and a female tree close enough together for pollination, then the seed must fall into ground that is "anerobic" because it has been flooded. With modern farming methods, there are few places that meet these conditions.

He also pointed out the different types of willowherb in the reserve. There is Rose-bay Willowherb near the railway, some Great Willowherb near the stickleback bridge and, new to me, Hoary Willowherb near the places where we were working.

The time just whizzed by. While I was at the reserve, I saw several butterflies including colourful commas, pretty little moths and all sorts of intriguing insects.

A weird little Tortoise sheildbug.
As a gardener, I'm not a big fan of molluscs but I was rather taken with the golden coloured snails I found in the Balsam.

When I had had enough, I pottered off home, stopping briefly to check out the spot where I had previously seen a stickleback nest. I didn't see any fish this time but there was a variety of flowers including yellow loosestrife.

Views (Williams) Wood - Repelling the invasion

A little while ago the Woodland Trust asked for some volunteers to help Sandra, of the TrUck project, to remove some of the Himalayan balsam which, in their words, "is getting a foothold in a couple of places within the wood". A couple of months ago I had noticed small seedlings beginning to grow amongst the bluebells and other wild flowers. Now those 'seedlings' are taller than I am. If left to grow and spread, they would soon overwhelm the other wild flowers and cause other problems as explained in The River Uck - not so pretty in pink.

Unfortunately, I couldn't join the rest of the party so I went and did some by myself. As described in an earlier post, I have done this before and am happy that I can identify the plants properly.  The work itself is reasonably easy, it is just a matter of pulling up these shallow rooted plants and stacking them by the path.  I was there from about quarter past nine and had the wood more-or-less to myself. The only noise was birdsong and church bells, which was lovely.  While I worked in the shade of the trees, I saw many different types of wild flowers including dainty enchanter's nightshade, speedwell and red campion.

As I progressed and the heap of discarded Himalayan balsam got higher inquisitive dogs nosed around my work and their owners stopped for a chat. Later joggers and family groups passed by.

After about two and a half hours I went home, having spent an enjoyable morning getting rid of an alien invader - and don't worry - I'm not greedy, there is more balsam for other people to pull up.

Repelling the pink alien invaders

Yep, It's balsam bashing again. I appreciate that this has been a regular topic on this blog, but removing balsam from the Hempstead Meadows Nature Reserve has dominated my Saturday mornings for the last 6 weeks. This week was particularly rewarding as Matt (the local ranger) had rounded up about half a dozen of us including Lee and Josh, who each managed to pull as much as the rest of us put together. It was the usual routine of identifying the balsam, pulling it out and leaving it by the side of the path to dry.


An armful of Himalayan balsam

All the plants in the reserve are growing tall now making it difficult to get at some of the balsams. A thick sea of nettles and other plants on the North side of the path prevented us from getting to some that are already in flower. If we can't get to them before they seed, there will be many more to pull up next year.

This sort of task day, for Hempstead Meadow and Uckfield's other green spaces looks to become a regular feature of town life. I find it tremendously satisfying work and it is a real antidote to a working life spent hammering away at a computer keyboard. If you feel like getting involved, ask Matt to put you on the email list.

As an aside, on the way home, I saw two young robins searching for food at the South end of Lime Tree Avenue. They have the same rounded shape as the adults but not the red breast.

Now at home and chilling out after fighting the alien invador. What should I watch? Doctor Who or War of the Worlds?

Alien Smoothies versus Uckfield Roughs

We are still removing Himalayan Balsam from the Hempstead Meadow nature reserve, run by Uckfield Town Council.  Although the pink balsam flowers are lovely, the huge plants would simply swamp the wide variety of native plants in the reserve. The picture below shows a pretty, delicate looking crosswort, which in another week, would have been swamped by the nearby balsam seedling.

The balsam plants are getting bigger now. Some of the biggest were two and a half foot high (about 70cm in new money) but seedlings are still coming through so we still need to look out for those. The plants are quite easy to pull out of the damp soil. The trick is to grasp them as near the bottom of the stem as possible and pull gently but steadily.  If you snatch at them their sappy stems just break at the joints.


Balsam plants left on the side of the path to dry out.
The young balsam plants are similar to many native plants so we have to be careful to pull out the right ones.  The photo below shows some of the differences.


Differences between balsam and similar native plants.
Himalayan Balsam Native Species
Leaves - smooth
Colour - light, sometimes has a reddish tinge, especially around the veins
Stems - pale, smooth, and very sappy
Leaves - often rough, even if only slightly; or hairy
Colour - often darker and I've not seen a red tinged one yet
Stems - often darker, rougher

To sum up, the alien invaders are red-tinged smoothies while the Uckfield natives tend to be a bit on the rough side. What can I say?

There are a couple more work days to go (Saturday mornings, meeting by the Waitrose carpark gate at 9.00am). See the council website for more information.

Hempstead Meadow in June

I felt rather guilty about marching through Hempstead Meadow Nature Reserve on Saturday.  I had my hair trimmed and the grey touched out, which took most of the morning. Obviously it is the trim that takes most of the time! Unfortunately this meant that I couldn't join the working party who were removing the Himalayan Balsam as described in last week's post.

I did get a chance to look at the trees and June's selection of wild flowers.  Most of the blossom and the delicate spring flowers have gone but others have taken their place.


Hawthorn blossom and black poplar tree (just right of centre).
The first treat was the Hawthorn blossom. This is really thick on the bushes this year. The 5 black poplars that were planted about 15 years again are fine looking trees with shimmering shiny leaves.


Meadow Cranesbill
In the dryer meadow area, I found blue meadow cranesbills. This is a real treat, I have never seen one growing wild before. Once I get closer to the wet areas there is loads of treacherous white and frothy hemlock water dropwort.


Pulled up balsam
I have a quick chat with the working party and then move on. The pulled up balsam on the side of the boardwalk is clear evidence of their efforts.

It was a very short visit as I dashed back from the town to home, but that is the beauty of this local reserve. I can take in its beauty and tranquility without making a special journey.

Exterminate! Ridding Hempstead Meadow of alien invaders

Each Saturday in June, starting today, there is a task day in the Hempstead Meadow Nature Reserve. The idea is to remove the pretty but thuggish Himalayan Balsam. A group of us located and pulled up seedlings to stop the adult plants overwhelming the native flora later in the year.


Himalayan Balsam seedlings, circled.
As the photo shows, at the moment the seedlings look small and inoffensive but later in the year the plants will be taller than me and causing all sorts of damage as described in TrUck's blog post on the subject. We have to be careful when doing this because we are 'invading' the nature reserve ourselves and are in real danger of tramping the plants and scaring the birds that live there. It was a rather lovely experience, methodically scanning the foliage looking for the slightly red tinged leaves of the balsam and listening to the bird song all around. Martyn Stenning, who was leading the group pointed out the song of several african migrants such as:
We have to be particularly careful not to disturb or damage the nests of these birds, which are found in vegetation close to the ground.

Balsam seedlings. Some of the tallest were already a foot high.
We took some time to peer into the clear areas of water next to the board walk.  I saw loads of wriggling tadpoles, about 3 sticklebacks, whirligig beetles, pond skaters and loads of caddis fly larvae. The latter are something I have often read about or seen on the TV but have never seen. They are strange little creatures that build an outer jacket out of bits of stick and debris. One, perhaps a caddis fly fashion victim, had decorated its brown coat with bright green disks of duckweed.

Further along the boardwalk we got a good view of Uckfield's primeval swamp.


Greater tussock sedges in Uckfield's primeval swamp.
Ancient plants like the tussock sedges and horse tail give the swamp a genuinely primeval feel. I almost expected to see a dinosaur lumber out from behind a clump of trees.  Returning to reality, we cleared the reptile basking rocks in case the resident grass snakes, slow worms and lizards wish to do a spot of sun bathing.  

There are more task days, running from 9am to 1pm each Saturday in June, so do come along. There is more info in my earlier post.
