Canadian baseline monitoring shows healthy Horse Creek
Baseline monitoring conducted by the Little Creeks and Rough Fescue Appreciation Society showed that Alberta’s Horse Creek is healthy but still threatened, according to a Rocky View Weekly article. 
 The initiation of the study was one of the main goals of the nature loving group of Canadian women. It is now in its second year. 
 They collected funds to hire a consultant to monitor the creek. Parameters such as temperature, dissolved oxygen, pH, conductivity, dissolved and suspended solids were measured. The study also examined nutrient intake into the creek. 
Monitoring showed the creek was in relatively good health but is threatened by excessive water flows from nearby Cochran Lake, nutrient loading and inflow of higher conductivity water.

In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. 
 
In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. 
 
The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.

Human interaction has negatively impacted the hundreds of streams that run through Southern California. Man-made river and stream diversions, channeling, and damming have changed the physical and chemical characteristics of these waterways. In addition to physical impairments, climate change is increasingly impacting the ecosystems of streams. 
 
To evaluate and mitigate these negative impacts, local groups are monitoring the riparian habitats of these streams and are conducting water surveys that document rainbow trout populations and evaluate water quality .
