30 Days Wild day 26- Wildlife on holiday


I spent the end of June on holiday with my parents in Norfolk. This was mainly to give us all a bit of a break before the annual village carnival which my dad organises. However, we happened to be staying in a forest, which was great for finishing off 30 Days Wild (although awful for getting any blog posts written because there were always more exciting things to be done).

Before we'd even finished unloading the car, I'd spotted the treecreeper and the nuthatch. The rest followed not long afterwards, either seen from the deck of our cabin or on a quick walk through the forest. Every rustle of the leaves was something new to look at, and it didn't take long to tune our eyes in and start picking out movement amongst the trees.

30 Days Wild day 27- Tree ID

Today I decided to continue my quest to improve my identification skills. This time, I thought I'd make the most of my smartphone and try out some of the many apps available for identifying trees. There are so many to choose from, and they are fantastic tools both to speed up identification and to begin to teach yourself. What's even better is that so many of them (and all the ones I tried) are free. 

The first one I tried out was Leafsnap. It's an incredibly clever idea; you take a photo of a leaf, upload it (you need an internet connection to do this) and the app suggests which trees the leaf could have come from! From the half an hour I spent playing, it seemed to work well. However, it did struggle some of the time, especially with the pinnate leaves of elder, mistaking them for an oak.


While it isn't always accurate and is internet dependent, it's an incredibly fun tool and one I'll definitely keep using!

Next, I downloaded the Woodland Trust British Trees app. It's basically an electronic version of an identification key, narrowing down the number of possible trees as you go through a series of questions. I particularly like the way it can use flowers, fruit, bark, twigs and buds, as well as leaves, for identification. It means that you can still use it if the tree isn't in leaf, and you can more easily differentiate trees with superficially similar leaves. Also, doesn't require an internet connection, so you can use it no matter how far from internet you are!


I found this a really useful and functional app- definitely one I'll be using in the future! That being said, I enjoyed leafsnap too, and it includes a few ornamental species, so I think I'll be keeping them both! If you've tried one of these, or any other good ID apps, I'd love to hear from you in the comments.

30 Days Wild day 14- Lime galls

I was on campus again today and saw something which I'd never noticed before. Some of the trees were covered with strange, red, pointed growths. I decided to find out what they could be.


I like to think I'm reasonably good at tree identification, but this wasn't one I immediately recognised. So I took some photos and went online.


It turned out to be a common lime. Because it's a species often used as an ornamental tree in parks, gardens and residential areas, there was lots of information about pests and diseases online. This meant the galls were very easy to track down.


It turns out that the galls are created by mites (Eriophyes tiliae and E. lateannulatus). They are sap feeders, producing chemicals which cause the galls to grow. They then feed on the cells surrounding the gall, which provide more nutritious sap than other plant cells.

It's just one example of the fact that it's not only the big, charismatic mammals and birds which are interesting. Everything in nature, even the very smallest things, can be utterly fascinating.
