The Faces of REEF: Member Spotlight, Keith Rootsaert


REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.

This month we feature Keith Rootsaert (REEF member since 2009). Keith is a member of REEF's Advanced Assessment Team in the Pacific Coast region and has conducted 138 surveys. He has become one of the Pacific region's most active surveyors, and during our interview, revealed that he is gunning to be the top surveyor someday! Keith has also started teaching marine life ID and is an instructor for our newest training tool, the Fishinars! Here's what Keith had to say about REEF:

When and how did you first volunteer with REEF or become a REEF member? I first found out about REEF at a 2009 Great Annual Fish Count event sponsored by the Dive Club of Silicon Valley at Lover’s Cove. This was my first and second surveys and when I first met Alex Matsumoto and John Wolfe. Over the years I dove with them many times and expanded my knowledge and interest in REEF. Now I am a level five Expert and I teach Fish and Invert ID seminars at the Monterey Bay Aquarium with Alex.

If you have been on a REEF Field Survey, where and what was your trip highlight? I have attended the West Coast REEF Advanced Assessment team survey of Monterey Bay National Marine Sanctuary the last two years and it is always fun to do surveys with fellow fish geeks. Even though it is just for fun, there is always an element of competition among these adventure seeking divers. At the onset of the trip we all pick a number for the total number of fish species we will survey. My first year on the team I was closest at 55 species and won a postal fish stamp sheet which I have on the wall in my study.

What inspires you to complete REEF surveys? I first started diving in Monterey Bay in 1984 and there were a lot more fish back then. Over the years I have noticed a gradual decline until now there are not as many and not as big fish as before. REEF helps me to share my actual observations in my dive log with scientists that can crunch that data and make informed decisions about conservation. For me, knowing what I am looking at makes all the difference in the world, it makes diving interesting and sharing my surveys and teaching others to properly survey and identify fish helps me to feel like I am giving back to community.

What is your favorite part about being a REEF member? I have resigned myself to being a competitive fish geek so after coming in second place in the number of surveys in California in 2010 I set out to do the most surveys in California in 2011. About November my number was looking good for California in 2011. So then I had to ask Janna Nichols about my chances of being “Best in the West”. The PNW divers have a solid base of divers and there was just no way to catch them. California has so many more divers but less than half the total number of surveys done in the PNW. My future goal is to help grow the California survey group and become Best in the West. Look out Randal T. - you’re going down!

What is the most fascinating fish encounter you’ve experienced? My most fascinating fish encounter just happened recently. In mid-December, we were diving at the Metridium Fields like I’ve done 50 times before and my buddy was staring over my shoulder. I looked to my left and two feet away was the eye of a four foot Ocean Sun Fish (mola mola). I tried to approach it but it backed away but then it followed us and at times led us back on a reciprocal course. It was just magical to watch this huge fish swim/row above the bright white plumose anemones.

Putting It To Work: A New Non-native Fish in the Gulf of Mexico

Last year we shared an article about a new non-native fish, the Regal Demoiselle (Neopomacentrus cyanamos), showing up in the southwestern Gulf of Mexico. REEF surveyors in the Yucatan region of Mexico have since reported the species. And now a new publication co-authored by REEF staff Lad Akins documents that the species could become established and spread in the western Atlantic. The study incorporated a computer model to evaluate the the non-native species’ potential to impact native populations. On the basis of this work, it is foreseeable that the reefs presently harboring Regal Damselfish will likely see increased abundance of this damsel. Immediate attempts to eliminate the fish, therefore, should be focused in nearshore shallow waters spanning Veracruz to Frontera, Mexico. To find out more about this study, published last month in the journal Marine Biology, and to see a complete list of the 50+ scientific publications that have featured REEF data, visit

The species is native to the Indo-Pacific and Red Sea. Similar in appearance to the native Brown Chromis, the Regal Damsel is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill, and yellow rear margins of the fins and tail. In contrast, the native Brown Chromis is identified by dark margins on the tail and a dark spot at the base of the pectoral fin.

If you see this fish while doing a REEF survey, be sure to report it on your form in the unlisted fish section. Please also report detailed information on the sighting to REEF through the invasive species reporting page.

Double Your Donation and Support REEF Discoveries

On World Oceans Day, REEF kicked off our annual summer matching campaign. Every donation that comes in through August 8, up to $40,000, will be matched dollar for dollar! We are highlighting all the exciting new discoveries REEF staff and members are making through our core programs. With your help this summer, REEF can continue to study the vast underwater world that remains largely unexplored and encompasses more than 70% of our blue planet.

To make a contribution, please visit

If you are a regular reader of Making It Count, you may have already heard of these exciting discoveries. They are significant steps forward in marine conservation efforts, and it is only possible through donor support, citizen science, and the help of our members, that we uncovered:

  • Previously undescribed species, including a Coralblenny from the Philippines, Eyre’s Dwarfgoby, from Fiji, and Alfian’s Flasherwrasse from Indonesia 
  • Nassau Grouper can travel up to 275 km during their reproductive season (with this finding, the Cayman Government recommended seasonal protections rather than fishing closures only at reproductive locations) 
  • Ongoing lionfish removals can suppress the invasion to a low enough level to allow for the protection and recovery of native fish populations on Caribbean reefs

From all of us at REEF, we sincerely thank all our donors who make this work possible! Please have a safe and fun-filled 4th of July!
