Description
Specifications
  • Name Trails guide users through a simple key to help them to identify the plants and animals that they find
  • Text on the reverse side of the charts provides further information
  • Splash proof and wipe clean for outdoor use
  • They are small enough to take into the field as the charts fold to B5 size (approximate size: 240 x 180mm)
  • Need to identify minibeasts in ponds and streams? The FSC Freshwater name trail fold‐out guide has been used by generations of visitors to FSC Field Centres
  • The simple flow chart on this guide shows representatives of the main groups found in ponds and streams
  • These include animals with no legs, such as hydra, flatworms, true worms, leeches and molluscs
  • Plus the animals with jointed legs, such as crustaceans, insects, spiders and mites
  • Freshwater insects include those with nymphs (such as mayflies, dragonflies and damselflies, stoneflies and water bugs) and those with larvae (such as caddis flies, beetles, alderflies and true flies)
  • As well as making a simple list of minibeasts, the Freshwater Name Trail supports many different investigations
  • How do minibeasts breathe underwater? Different animals obtain oxygen in different ways
  • For example, flatworms, leeches and snails can absorb oxygen through their skin
  • Other animals, like mayfly nymphs, have gills
  • These gills are easily to see moving on the live animal
  • Mosquito larvae, water scorpions and rat‐tailed maggots use a 'snorkel'
  • And a few animals, like water spiders, collect air bubbles from the surface
  • How are minibeasts move through water in ponds and streams? Some animals, like leeches, flatworms and flattened mayfly nymphs, are streamlined
  • Are the animals that live in moving water shaped differently to those that live in still water? Can you compare the deep and shallow parts of the same pond?
  • How clean is the water? Since different animals tolerate different levels of pollution, you can use the list of minibeasts you have made
  • The guide features a simple biotic index
