'BioBlitz' is one of the big buzzwords in the world of ecology at the moment. It's short for 'Biodiversity Blitz' and it's an intensive day-long or weekend-long survey of all the plant and animal species in a specific area. Experts are on hand to identify every species of bug, bird, flower and fish but the surveying and collecting is done by anybody who wants to come along and get involved. In this week's programme Flintshire's Biodiversity Officer, Sarah Brown, pops in to tell Adam about the Flintshire BioBlitz which takes place at Wepre Park near Connah's Quay on Saturday 31st July.

And while we're on the subject of biodiversity, Science Cafe reporter Tracy Cardwell investigates a new initiative by the Forestry Commission to map Wales' ancient woodlands using the latest technology. She visits Halton Wood near Chirk and discovers just how many species make their home in these woodlands. Back in stduio, Adam is joined by Rory Francis from the Woodland Trust/Coed Cadw and Adam Thorogood from Llais y Goedwig to discuss the effect of climate change on Welsh woodlands and the campaign to plant 20 million trees across the UK in the next fifty years.

And to conclude Science Cafe's own bioblitz, Adam puts in a call to Prof. Graeme Hays from Swansea University to ask him why he's spending his summer attaching electronic tags to jellyfish off the Welsh coast. The answer is that it's part of an international research project on how ocean predators track down food. The theory - based on mathematics - is that a predator searching for food will make a long journey to get it to a new area followed by smaller movements as it quarters the area for food. And how do you tag a jellyfish? Very carefully of course!
