Exploring Biodiversity at Reed Hall Pond: A Comprehensive Study
Discover the rich biodiversity of Reed Hall Pond through a bioblitz pond dip event led by Derek Harper. The study involved sampling at six sites, yielding findings of 23 different animal species, including fish, snails, mayflies, damselflies, caddisflies, beetles, water bugs, flies, crustaceans, water mites, oligochaete worms, leeches, and aquatic plants. The analysis also delved into canopy shading impacts and reasons for observed phenomena, leading to corrective actions to enhance the ecosystem's health.

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 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
