SAX-ZIM BOG BIOBLITZ VII WRAP-UP July 20,2019
Early rain couldn’t dampen the spirits of over 50 participants who explored Sax-Zim from top to bottom on Saturday. The weather just kept getting better throughout the day and it was hard to come back from the field! But everyone did return and it was so much fun to hear about all the group’s finds and adventures. Preliminary results show that we DOCUMENTED OVER 660 SPECIES of flora and fauna! Amazingly, this is about 45% of our entire Master List of 1500 species!
