This research aims to examine how historical land use affects the current diversity of stream invertebrates and fish.
Compared watersheds with varying land-use histories from the 1950s and 1990s.
Analyzed the correlation between past land use and present-day biodiversity measures.
Watershed land use from the 1950s was the strongest predictor of current biodiversity.
Riparian and land use from the 1990s showed weaker relationships with biodiversity levels.
Long-term agricultural activities significantly reduce aquatic diversity, even with efforts like reforestation.
