Grass structure for beginners:
Came across this photo stream this morning whilst doing some research.
Looks as if the photographer knows his business both as a wildlife observer and as a photographer. Some excellent examples. My knowledge is not that good to judge the validity of his observations, but his stream is worth a visit anyway. I have certainly bookmarked him for future reference.
Just taken a look myself, and indeed it is worth visiting!

Wouldn't it be nice if someone made an iSpot key for grasses! If anyone is interested in giving this a go, we can help you. Contact us through: http://www.ispot.org.uk/contact
