I've started a new short series within Test Tube all about trees.
Links to all the videos will be posted at test-tube.org.uk/trees
The videos feature ecologist Dr Markus Eichhorn and I've found he's quite good and discussing a mixture of things - the science, history and trivia of each species.
The first video we've posted is this one about elms.
Next week is a really good one about oak trees, so watch out for that.
We went out earlier this week and filmed about 10 types of tree and I found them all quite fascinating.
Good ways to follow the series is subscribe to the nottinghamscience YouTube channel or follow me on Twitter.
