Myristica swamps, unique tropical freshwater ecosystems of the Western Ghats, are rich in biodiversity and critical habitats for benthic macroinvertebrates. This study assessed their population dynamics, diversity, and ecological indices in Kulathupuzha and Shendurney, focusing on environmental factors such as water and sediment quality, forestry activities, and seasonal variations. Macroinvertebrates were analyzed using PCA, indicator analysis, and correlation analysis to evaluate their relationship with physicochemical parameters like dissolved oxygen, pH, and nutrients. Kulathupuzha exhibited higher macroinvertebrate density (8,438.95 ind/m²) than Shendurney (7,420.36 ind/m²), with pollution-sensitive species like Odonata, Trichoptera, and Plecoptera indicating good water quality. Seasonal variations influenced species abundance, with pre-monsoon showing the highest density (7,703.26 ind/m²). These findings highlight the need for ongoing monitoring to manage environmental impacts and support conservation efforts in these vital ecosystems.
