Invasive Non-native plants along Water of Leith

Yesterday evening I went along to the annual Invasive Plant species walk organised by Water of Leith Conservation Trust (WOLCT) for their patrol volunteers. We had a lovely walk trhough the downstream area of Colinton Dell. Hard to believe now, as the rain pours down and the wind howls, but yesterday evening was beautiful and mild and sunny.

The main three invasive plant species that are an issue along the Water of Leith are:

Giant Hogweed is a problem because it can cause burns and scarring if you come into contact with it. It is also very invasive as it produces lots of seeds which can stay fertile for several years. It is however popular with quite a few insect species. WOLCT manages the plant by closely targetted spraying with glyphosate, which is the only herbicide that can control the plant.

Himalayan Balsam is a problem because it is very invasive, as it produces vast numbers of seed. It can totally take over an area and stop anything else from growing during its own season. However, because Himalayan Balsam flowers late, it provides food for bees when there's not much else around. Also it doesn't stop the early spring flowers from thriving. We know from our visits to Dumfriesshire, that areas that are covered in Himalayan Balsam in summer are full of a variety of spring flowers earlier in the year. The real problem occurs by rivers where the growth of this plant can erode riverbanks. Plus it smells vile so I'm more than happy to help WOLCT control it by pulling up the plants I find while I'm patrolling the river.

Japanese Knotweed is one of the most invasive plants in the world. It spreads mostly through its roots and can undermine the foundations of buildings. (If you have Japanese Knotweed in your garden, you are likely to be unable to sell your house). It is very difficult to control, currently the WOLCT is trying to eradicate a patch in Colinton Dell and it will take at least a couple of years more to get rid of it, injecting herbicide into every stem of the plants.

Two other plants are giving some concern in Colinton Dell:

Few flowered leek in some areas of the Dell is already taking over from the native wild garlic. One possible way of controlling its spread is for foragers to pick and eat the leek rather than the garlic. Having said that, the number of dogs that run around (and do other things) in Colinton Dell, makes me nervous of foraging anything that grows on the ground there.

Salmonberries have sprung up in one area of the Dell. I've not really been able to find out much about the status of salmonberries in the UK, they've been here for decades, but I'm only aware of them becoming a problem very recently. WOLCT is looking into how best to control them.

The Seaside Horses

Garishly painted horses dash up and down, round the carousel, maddened by mechanical pop songs from yesteryear. White horses canter in the sea, strangled by seaweed and stung by salt spray. No-one rides the carousel horses. No-one swims with the white horses in the sea. No-one is around to turn off the tinny music. The restless horses gallop endlessly in their own little worlds, waiting for the freak high tide that will bring them together.

The Man Who Gave Away His Island by Ray Perman

This is a biography of John Lorne Campbell, who bought the Scottish island of Canna in 1938 and lived there until his death, though he gave it away to the National Trust of Scotland in 1981, while continuing to live there.

This is a history of the Campbells of Inverneill and the financial problems that lead to John Lorne Campbell being disinherited from his family lands and eventually buying Canna. It's also an account of Lorne Campbell's work as a Gaelic scholar, an entomologist and laird of the island.

At times the book gets very bogged down in the details of financial and administrative issues that plagued both the Campbells of Inverneill and Lorne Campbell himself. Overall though it is a fascinating book. Lorne Campbell's exhaustive work in collecting Gaelic folksongs and folklore from across Scotland, Ireland and Nova Scotia lead to the Canna House library becoming the most important Gaelic language archive in the world. The House also became a cultural centre with writers and artists regularly visiting from across the globe.

The book also looks at the traditional life of Canna and the struggles to keep a reasonable population living on the island, not helped by official attitudes to crofting (the island's traditional way of life) and poor transport links. This takes the narrative into an interesting discussion about land rights in Scotland.

The book all too briefly looks at the wildlife of Canna, noting how the relatively recent eradication of rats from the island has allowed the native sea bird populations to recover to seome degree.

An essential read for anyone interested in Scotland and the islands.

Coming Soon - Scotland's Big Nature Festival

Musselburgh Boating Pond, Levenhall Links

The Scottish Big Nature Festival (which includes Scottish Birdfair) takes place this year on 23 - 24 May at Levenhall Links in Musselburgh, my favourite place for birdwatching!(I was there today and saw shovelers and gadwall at the Mouth of the River Esk and several ringed plovers and dunlin on the Lagoons along with 2 grey partridges and several other birds. Plus there were plenty of swallows around).

The Big Nature Festival has a packed programme of events on all aspects of birding and nature, including events for children and families,including 'design your own nature superhero' which sounds particularly exciting, I might go along and see if I can design a super-hero rabbit (as rabbits are the only animals I can draw!).

Lots of exhibitors will be present to offer information on all aspects of birdwatching and enjoying the natural world in Edinburgh and further afield. 

There will also be opportunities to take part in birdwatching walks around the area,  a bird ringing demonstration and  a cruise through the Firth of Forth.

So there really will be something for everyone and the money raised from the event will go towards conserving the curlew, an iconic wader. The UK supports the third largest breeding population of curlews, but numbers have halved in Scotland since 1995. Curlews are frequently seen (and heard) around Musselburgh Lagoons and the Firth of Forth, so it's a highly appropriate choice. You can read more about the RSPB's work for curlews here.

Cherry blossom

The cherry trees are wonderful at the moment

I particularly like the (relatively rare) trees that have both pink and white blossom, like this one we saw in Dalkeith Country Park yesterday

Dalkeith Country Park in bloom

We both had a midweek day off today and went to Dalkeith Country park. It's most notable for its oak woodland, this isn't just ancient woodland, but amazing, ancient trees, that have lived through many hardships and still survive

Dalkeith Country Park is also famous for its bluebells. We were slightly too early for the main display of these wonderful flowers but quite a lot of them were out

The flower that stole the show though was the dog violet, which was everywhere! I've never seen so many violets, they were carpetting the ground in places.

There were also a couple of clumps of cowslips

and also the wild strawberries were in flower (surely earlier than normal?)

We were delighted also to have lovely views of a nuthatch, a treecreeper and a great spotted woodpecker, none of which were kind enough to pose for the camera!

Wood sorrel and ash flowers

The ash trees in Colinton Dell are blooming just now

and the wood sorrel is looking lovely too, specially this area, where it's growing in amongst moss on an old wall.

Wood sorrel is one of the plants that indicates ancient woodland, again showing that Colinton Dell has been woodland at least since 1750. This doesn't mean of course that all the trees are that old! In fact very few of the individual trees are likely to be that old. Colinton Dell was for many years a place of great industry as there used to be several paper mills along the Water of Leith. Most of these have become entirely derelict and many are now woodland again.
