    Hi Friends of Sausal Creek,<br>
    <br>
    Please join the bioassessment team for aquatic insect monitoring
    this Sunday, February 5, 9 a.m.-1 p.m.  The team will gather at the
    Scout Hut in Dimond Park and team member Travis Peterson will
    discuss the team's findings so far, analyzing this data alongside
    data collected in 2000.  The team will then split into two groups,
    one to perform monitoring in Dimond Canyon, and the other will go to
    Palo Seco Creek to perform monitoring.<br>
    <br>
    RSVPs are encouraged so enough handouts can be prepared, please. 
    RSVP to Kathleen Harris at <a moz-do-not-send="true"
      class="moz-txt-link-abbreviated"
      href="mailto:kathalini@comcast.net">kathalini@comcast.net</a>. 
    Please note that this event is for adults only.<br>
    <br>
    Attached is a report from the team's January monitoring.  The report
    is also copied below for listserv digest recipients who cannot
    receive attachments.<br>
    <br>
    A huge thank you to Kathleen Harris and Travis Peterson for their
    team leadership!<br>
    Kimra<br>

      (9 a.m.-1 p.m., meet at the Scout Hut in Dimond Park). We are
      going up into Joaquin Miller Park to sample an area that was part
      of the bioassessment effort some years back.<span style="">  </span>That
      site will be away from roads and culverts.<span style="">  </span>We
      will also continue sampling in Dimond Park to get an idea of the
      numbers and types of organisms we can expect to find in the creek.</p>
