Reef Check Data through the end of 2021 on inverts, kelp, and UPC is now available via the data request form on or website. Fish data and 2022 data will be available soon! https://t.co/Me5hFNbDhM

As far as I know this the first #pycnopodia seen in California in a long time.

#WSN2022 such an amazing conference! So great to see so many friends and colleges and to see so many great talks, including two from Reef Check about some of our kelp restoration projects. #kelpforests

"We learn our indicator species and then we stop looking at and IDing other species."

David Kushner, Naturalist of the Year, #WSN2022

I'm so guilty of that. I'm going to try to change that about myself and from now on be constantly looking for things that aren't on my list.

At Tankers Reef in Monterey, hundreds of divers with G2KR have volunteered their time and energy in the effort to reduce the urchin population. The results speak for themselves.

[Dan Abbott @ImpatientGopher]

One year ago this site was an urchin barren with very little kelp. Today it's a healthy kelp forest where the urchins are tucked back in cracks, passively feeding on the drift algae. #kelprestoration #kelp #kelpforest #tankersreef

[Dan Abbott @ImpatientGopher]

Reef Check has been involved in kelp restoration for going on five years, and in that time we have never really achieved the goal of flipping barren areas back to full-fledged kelp forests--until now.

Great article in this morning's SF Chronicle!

Our team in Washington came across an aggregation of sunflower stars during a survey on Camano island last weekend. They saw "hundreds of little pycnopodia, most were between 10-13 cm and few were larger 25-40 cm." #sunflowerstar #pycnopodia #reefcheck #citizenscience #kelpforest

New data collected by Reef Check shows that kelp restoration efforts at Tankers Reef off the coast of Monterey have resulted in the significant growth of giant kelp! The density increased roughly fivefold from 33 stipes per 100m2 to 150 per 100m2 from March 21' to Sept 22'

It's inspiring to see so much effort put into restoring California's kelp forest by recreational divers (G2KR), citizen science divers (Reef Check), and members of the scientific and management communities including CDFW, NOAA, and OPC.

Was out with Reef Check Oregon this week doing surveys around Port Orford, including at Arch Rock on Orford Reef. Oregon has experienced a significant loss of kelp similar to Northern California but there is less data in Oregon so the extent of the loss is less well understood.

[Dan Abbott @ImpatientGopher]

According to Tom Calvanese at the OSU Field Station, Ordford Reef used to support a massive kelp forest, but all we saw was a few individual bull kelp plants and a carpet of urchins. The good news is that this issue is now being studied and efforts are underway to restore kelp.

@Trawler1x1 Thanks

[Dan Abbott @ImpatientGopher]

Finished up surveys along the #SonomaCoast this weekend. Sites look unchanged from the past full years. Absolute #urchinbarrens with almost no #kelp and a lack of invertebrate diversity. I saw no #abalone. One observation of interest is there are very few small urchins (<4 cm).

[Dan Abbott @ImpatientGopher]

@Trawler1x1 Trawlers were blamed for kelp lost? Were they fishing urchin predators? Now I’m the one who needs the explainer.
