This Saturday, May 9, San Diego River Days will kick off with events stretching from the river mouth at Dog Beach, through Old Town and Mission Valley, to Santee and finally Barona Reservation. River Days continues with more events on Sunday, May 10, and the following weekend (May 16 & 17). In Santee the Friends of Santee’s River Park will be coordinating a salt cedar (tamarisk) and trash removal project. If you have read some of my earlier posts on the river, you know that salt cedar is a dangerously invasive tree that causes severe habitat damage. If you are interested in helping out our local river, this is a good way to start. The local activities start at 9:00 am at Mast Park and run until noon. Other activities along the river have various times and locations, which you can find at the San Diego River Days site.
