Plas yn Rhiw

Plas yn Rhiw BioBlitz

A Bioblitz is a race against time to record the variety of wildlife found in a specific location. Join us on Friday June 2nd at Plas yn Rhiw to help us record as many wildlife sightings as possible.

Between 10am and 5pm there will be an opportunity to call in at the Bioblitz basecamp at Plas yn Rhiw to learn more about the species we’re hoping to find during the day and take part in wildlife themed craft activities. This is also where Cofnod the local record centre will be set up busy entering all the records online so that we’ve got a running total of the different species spotted throughout the day. 


A full timetable of activities have been planned with an array of wildlife experts ensuring we’ve explored as many of the different habitats found in the area as possible. All activities are free.
