Phytophthora Tree Disease

I've decided to concentrate on the Phytophthora tree disease in South Wales, in particular the Afan area.  On my first shoot a worker from the Forestry Commission showed me around the area where it a lot of the felling has happened, and it still happening. His job is directly involved with the Phytophthora disease so he has a lot of knowledge on it all.
I chose to shoot on black and white and colour 35mm for my first shoot so I could decide what looks better for this project. I was worried black and white would not work well in such a colourful environment. Here are some of the comparisons. I prefer the black and white images, however I do think the colour ones work well too.
I don't think it is clear from the images what the project is about, so in the final presentation I will be sure to add in a lot of textual facts explaining the disease and the actions the workers have had to take.
