Tree Walk

 I'm back from a few days away (I had an awesome time in Manchester) and I still have a lot to say about the Tree event on Saturday (which seems like an awfully long time ago now!).

At 2pm, there was a tree walk down the Offa's Dyke path, starting from the Treehouse Cafe just over Hay Bridge.  The day was wet, and cold, and grey, but still about 20 people turned up.  There was some talk of doing an adult talk and a children's talk, but they decided to just go with the adult talk, and let the kids tag along.  If they got bored, there was plenty to do in the woods along the path, where there are a lot of outdoor games set up.

I'd been expecting a walk that pointed out the different types of trees, and one person had brought along a tree recognition booklet - but it wasn't really about that.

One of the trustees of Botany and Other Stories was there to talk about problems like ash die back - there are a lot of ash trees on that stretch of the riverbank.  One of the dying ash trees is right next to the cafe, covered in ivy, and they're trying to save as much of the tree as they can because the ivy is really good for biodiversity, nesting birds, insects and so on.

The owners of the land, who are actually doing the management of the woodland, were along for the walk, and they pointed out the strip of land that they can't touch to manage it because it is an SSSI.  Apparently, back when the UK was part of the EU, the Welsh Government could get EU grants for wildlife if a certain amount of riverbank was designated as SSSI (Site of Special Scientific Interest).  So, there is nothing actually special about this bit of woodland, but it was there to make up the numbers - and they can't touch it, unless it's to pull out the Himalayan balsam, or thin out sycamore trees, which are counted as invasive.  So it's basically just sitting there.  Meanwhile the woodland around it, which is being managed, has enough light to the ground to encourage flower species that indicate ancient woodland, like bluebells and celandine, and wood anemone, which make the woods look so beautiful in spring.

Coming out to the (slightly flooded) meadow, we were experiencing a completely different environment.  For the past couple of years, the owner has been mowing the meadow.  They tried other ways of managing it, but nothing really worked well - now, though, the clear stretch of meadow between the trees supports a lot of insects in the summer, and there is enough space for the swallows and martens to get a long flight path to eat the insects, so that's working very well.  

They also pointed out a couple of saplings, just in the water.  These were elms - but sadly, since Dutch Elm disease wiped out most of the elms in the country in the 1970s, any elms that do start to grow get to about the size that these trees are, and then die.

It was rather sad to learn that the woodland that looked fine at a casual glance actually had a lot of dying trees in it (and there's nothing they can do to stop ash die back or Dutch Elm disease), but at the same time, it's a hopeful sign that the woodland is supporting 76 species of birds, along with everything that the birds eat.

There was also a bit of discussion about what sort of woodland we want to see in the future - what sort of trees should be planted to be more resilient to disease and climate change, and so on.

It was a fascinating walk - worth getting my feet wet for!  (I wore a pair of boots that I thought were waterproof.  They were not.).
