Something new I noticed on my last visit to RHS Wisley - a sign in the Glasshouse about a grass snake. Not sure if this is for a specific grass snake that's been seen around the Glasshouse recently, or if grass snakes are just becoming more common visitors indoors. Think I also saw a similar sign for some birds in another area of the Glasshouse (Robin and Starling?) but didn't get chance to get a good look at that sign.
