As the San Francisco Bay Area Network coho and steelhead monitoring crew wraps up the 2024-2025 spawner season, we are looking back at one of the busiest winters since the beginning of this monitoring program! We observed increased coho spawning in all three creeks we monitor—Olema, Pine Gulch, and Redwood Creeks. Olema took the cake with the strongest cohort of all.

This elephant seal breeding season, the single-day cow count peaked at 1,159 on 1/27, which is similar to last year’s peak count of 1,165. Pup counts were higher than the five-year average this season. This is likely due to the lack of strong storms this winter and thus high pup survival.

Since the early 2000s, ecologists who monitor rocky intertidal ecosystems each year have noted declines in a key intertidal seaweed commonly called rockweed. Rockweed is considered a foundational species, meaning that its presence is so important that without it the entire ecosystem would change radically. At Channel Islands National Park, marine ecologists are working with local scientists to understand the best methods to restore rockweed.

Estimates of visitor use levels are important for informing park management decisions. The spatial and temporal extent and resolution of visitor use estimates can limit how they can be incorporated into management decisions, research, or paired with ecological data. This article recommends how visitor use monitoring can be approached more systematically and then used in parkwide predictive models of visitor use. NPS Intermountain Park Science, 2025

Northern Colorado Plateau Network’s scientists use satellite observations of vegetation condition in Curecanti National Recreation Area with climate data over time to reveal how climate influences plant production and phenology. Knowing which of the wide range of 16 vegetation assemblages found in Curecanti are more or less sensitive to climate change can help managers understand what to expect over the next few decades, and plan for the changes coming their way.
