Founders Day is an annual celebration in Whittier, California, commemorating the city’s founding on May 11, 1887. This event honored the community’s origins and showcased the organizations that contribute to Whittier’s vibrant character. 

Whittier Conservancy actively participates in Founders Day, reflecting its mission to preserve and enhance the city’s unique character and quality of life. 

This year The Whittier Conservancy joined other local organizations to that offered family-friendly activities, educational displays, and entertainment. Participants enjoyed food, music, and learned about Whittier’s rich history and the efforts to preserve its heritage.

Trails area closed starting Monday January 13, We are expecting winds in the Preserve area.

We are continually monitoring the weather conditions, Due to extraordinary circumstances in the county and red-flag-like conditions, the trails are closed.

According to officials a red flag warning is:
A term used by fire-weather forecasters to call attention to limited weather conditions of particular importance that may result in extreme burning conditions. It is issued when it is an on-going event or the fire weather forecaster has a high degree of confidence that Red Flag criteria will occur within 24 hours of issuance. Red Flag criteria occurs whenever a geographical area has been in a dry spell for a week or two, or for a shorter period , if before spring green-up or after fall color, and the National Fire Danger Rating System (NFDRS) is high to extreme and the following forecast weather parameters are forecasted to be met:
1) a sustained wind average 15 mph or greater
2) relative humidity less than or equal to 25 percent and
3) a temperature of greater than 75 degrees F.

Thank you for your understanding and patience.

City trees play a vital role in urban environments. They improve air quality by filtering pollutants, provide shade that reduces heat and energy consumption, and enhance aesthetics, contributing to mental well-being. Trees also support biodiversity by providing habitat for various species and can help manage stormwater, reducing flooding risk. Additionally, they can increase property values and promote community engagement, making urban areas more livable and sustainable.
