New manuscript on Lake Rototoa in Auckland has been published!!

A new manuscript titled - Resolving 500 years of anthropogenic impacts in a mesotrophic lake: Nutrients outweigh other drivers of lake change - led by Dr Rose Gregersen (Victoria University of Wellington) has been published in the prestigious journal Environmental Science & Technology.

The research explores the history of Rototoa, a lake in the Auckland region of Aotearoa-New Zealand. The researches combined sediment core analysis with historical data, and ecological experiments to determine what was causing the decline in lake health in recent decades.

The researchers show that the health of the lake remained stable despite catchment deforestation and erosion, and the introduction of several non-native fish species. The most significant and sustained changes in lake health coincided with nitrogen and phosphorus fertilizers in the catchment.

Congratulations Rose on your excellent research!
