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)?
As a result…
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
The bioblitz pond dip at Reed Hall Pond yielded interesting findings, with 23 different animal species identified, including various insects, aquatic plants, and more. The study also highlighted the impact of shading, potential reasons behind it, and suggested solutions for maintaining a healthy pond ecosystem. Through data and images, the study showcases the diversity of life thriving in this natural habitat.
