  1. Reed Hall Pond A bioblitz pond dip • (The contributor of this photos is Derek Harper)

  2. Basic facts • 6 sites, 3 hours of sampling • 23 different animals • 1 fish • 1 species freshwater snail • 1 mayfly species • 2 species damselflies • 3 species cased caddisflies • 2 species beetles • 2 different water bugs • 1 species fly • 2 species crustacean • 1 species water mite • 3 different oligochaete worms • 2 different leeches • 6 different aquatic/emergent plants

  3. The site Sample site 4 1 5 2 6 3

  4. What we found 4 1 5 2 6 3

  5. Basic stats 4 1 5 2 6 3

  6. Canopy shading 4 1 5 2 6 3

  7. What’s going on? 4 Impact of fountain 1 5 2 6 3

  8. Number of taxa and Diversity 4 1 = Diversity index 5 2 6 3X 3 4X 3.6X 1 = 1 taxon, 2 individuals 3.4X 2,424 X

  9. Reasons? Shading = reduced light = less phytoplankton production? Shading = leaves = organic input, too much? Shading = hiding places for Koi carp = heavier predation of invertebrates? Poorer aeration (unlike other end with a fountain)?

  10. As a result… • Foliage trimmed back, larger plants removed • Leaf litter dredged • Removed choking pondweed • Whole pond aerated • Koi carp netted off • More habitats for invertebrates created • Second fountain running
