Monitoring Creek Health
Considerations
When: Year-round, but several days after a winter storm is the best time to make your visit.
Where: The best creek to visit in the Bear Valley Area is located near the Earthquake Trail. If you are staying at the Education Center, discuss the best location with the Clem Miller Director. Salmon viewing occurs at a seperate location from monitoring.
How: This unit may be used independently of all other units. If you want to use an additional unit during your visit, we suggest the Defining Habitats unit. This will give students a more complete understanding of other resources at Point Reyes National Seashore and their relationship to creek ecology.
Weather: The chart below lists average climate expectations based on previous years data. The weather is subject to change quickly and can vary dramatically from different locations within the Seashore on the same day.
