Hello and a very happy Sunday to you! So this week I have been using all my GIS skills once again but now I’m using them in my dissertation. If you didn’t know GIS stands for geographical information systems and is a really cool tool you can use to layer information that has a spatial element. Then you can build up the layers to see if there is a correlation between all of the information. I’ve talked about all the ins and outs with GIS before and you can read about it here if you’re interested.
In terms of GIS for my dissertation, I’ve been putting all my results from my field work onto a map to see if there is any connection between the biodiversity I’ve found and other spatial elements. Particularly when questioning whether the presence of trees in the hedgerows affect the general biodiversity. This is when I would show you my beautiful maps but I need to keep them to myself for a little while until my dissertation gets marked. However the basics behind it is I have mapped out the trees in my survey area as a layer and then I mapped over the biodiversity I found using the alpha biodiversity. This can then show me where the biodiversity is lower and if this happens to be where the hedgerows are dense with trees.
I’m using a similar technique to show the affect of badger damage on hedgerows. Badgers will often use the hedgerow to build part of their sets. This can often lead to lots of the plant life being destroyed. So I’m using GIS to see if that is an issue on my sample site too!
GIS is one of those tools that never fails to provide you with a fantastic figure and is a great skill for any budding biologist out there to learn!
Hello! I have been working on my dissertation for my masters which is all about hedgerows and their conservation. This has meant I’ve got to know the plants in Cornish hedgerows really well so without further a do here are 10 of my favourites!
- Red Campion (Silene dioica) – This is one of the most common wild flowers I found as part of my research. Traditional medicines used the seeds to treat snakebites and its genus name comes from the greek word sialon which means saliva.
- Stinging Nettle (Urtica dioica) – Easily the plant I was most aware of in my research because I had all the stings to prove I had found it. However, stinging nettles have their place in the hedgerow and provide an excellent habitat and food source for lots of my favourite butterflies.
- Hawthorn (Crataegus monogyna) – This was one of the main shrubs I found in my hedgerows. It can be extremely dense but provide food and habitat for up to 300 different species of insect. It was once said that if you brought a hawthorn blossom into your house illness and death were to follow so perhaps admire this plant from afar.
- Blackthorn (Prunus spinosa) – Another common hedgerow shrub also known by the name of sloe bush. It’s berries are commonly made into sloe gin but another interesting fact is that blackthorn wood was associated with witchcraft.
- Buttercup (Ranunculus repens) – Otherwise known as the species with the best latin name I have ever heard of. I commonly found creeping buttercup at the bottom of hedgerows. It used to be a favourite game of mine and my friends at primary school to hold a buttercup flower underneath each others chins and if you could see the yellow reflection of the flower it meant you liked butter. Not particularly sure why that mattered but it’s still a delightful little flower.
- Sycamore (Acer pseudoplatanus) – Fun fact sycamore trees are actually my favourite tree. They have the most beautiful colours in them all year round as the young leaves and stems are red before going green. They are actually an introduced species in the UK but they have been here since the 17th century. They can live for up to 400 years so I think the Sycamore is here to stay!
- Fools Parsley (Aethusa cynapium) – This one wasn’t very common so I definitely had to dig around to find it but I did! In some areas it grows quite commonly but every hedge is different.
- Dogs Violet (Viola riviana) – This is another very sweet wildflower that I found in my research. If you do happen upon a violet looking flower it’s more than likely going to be this one.
- Hazel (Corylus avellana) – This is another very common hedgerow tree. It provides an excellent resource for many other species but often suffers when cut back to vigorously. The stems are very bendy in spring so much that they can be bent into a knot without breaking!
- Hogweed (Heracleum mantegazzianum) – This species was introduced to the UK in the 19th century as an ornamental species and has since escaped from gardens and can be found in lots of areas. I found some specimens in the base of my hedgerows but was always careful of them as the sap from this species can cause irritation and even blisters.
If you fancy finding out more about hedgerows I’m talking a lot about them in my becoming a master series which comes out on Sundays!
See you soon!
