Invasive alien species can have big impacts upon our natural environment and native species. A good Alien Detective needs to be able to understand the nature around them and so, in this section, we’re got lots of activities to help you explore and investigate your local countryside.
Several of the most invasive aliens (Giant hogweed, Himalayan balsam, Japanese knotweed and American mink) are often associated with the river environment and riverbanks, so there are several activities to try around the river.
Don't forget over on the Alien Detectives Additional Information page there are contacts for SISI Project Officers, Fishery Trusts, Countryside Rangers etc. who might be able to help with some of these activities, like river dipping and electrofishing. There is also guidance about taking your group outdoors.
Section 6. Explore your local river and countryside
Go outside and explore - use all your senses to see what you can discover about the wonders of the natural environment around you.
Below are a whole range of games and activities to do while you are on your walk through the countryside or at the river.
6.1 River dipping
Explore your local river or pond and discover the creatures of the deep - what beasties lurk in the water? You'll be amazed to discover all sorts of freshwater invertebrates. (Outdoor - pond/river)
Arrange an electrofishing demonstration and you'll be able to see and learn about all the types of fish living in a river. (Outdoor - river)
6.3 Wildlife recording
Find out how and where to record the wildlife you see while you are out and about. Did you know there is a GB database that holds all the records? Have a go at submitting a wildlife record. (Indoor)
6.4 Caught on camera
Set up a wildlife trail camera and see what photographs of elusive wildlife you can capture. We've included lots of handy hints of how and where to set your camera. (Outdoor)
6.5 Pooh sticks and flow rate
Have a bit of fun with this old favourite and then add in some science to calculate the flow rate of your river or stream. (Outdoor - river)
6.6 Tracks and signs
What tracks, trails and signs of animals can you find while out and about? Tracking is an essential skill for finding out if native or non-native animals are present in an area, so learn to read the signs! (Outdoor)
6.7 Sound map
A great activity to help you use a different sense to explore the countryside around you by spending some time listening and quietly producing a sound map. (Outdoor)
