Kittiwake hotels in Tromsø: an update before the birds return.

We started lowering the density of sea urchins with volunteers in June 2025. At first, nothing happened, and then it was winter, quite dark as Tromsø stands 350 km north of the Arctic Circle.

☀️ But then the sun came back, and we started noticing a change: a thin brown carpet of seaweeds. And then different colors: red, green, brown.

🥳 But what we saw today (Sunday 5 April) is an incredible reward for the «Kelpers». These volunteers have been gathering twice a months for the last 10 months, braving the polar winter.

🛥️ Overfishing since the 1970s in Norway reduced the urchin predators so much that the green sea urchin –a native species here– soon became super dominant and overgrazed kelp forests. In most places, in Northern Norway especially, these underwater jungles have been replaced by biological deserts called urchin barrens.

Rissa’s kelp restoration efforts with volunteers are part of the Ocean Green project, which aims at large-scale restoration of kelp forests.

Our two sites in Tromsø (Sørsjetéen and Telegrafbukta) show that reducing the grazing pressure triggers the return of seaweeds and kelp naturally, and very fast.

🤔 But what if we stop removing urchins? The answer is simple: they invade and overgraze the restored areas.

The populations of urchin predators need to be diverse and abundant again. Before industrial fishing, urchins and kelp forests coexisted.

🤝 @arktiskmuseum and @uitnorgesarktiske are key collaborators at the Telegrafbukta site.

🤝 @sut_dykk the student diving club facilitates this initiative by providing diving gears to the volunteers.

👐 A very warm welcome to Rachel Thume, who is doing an internship at Rissa Citizen Science. Rachel has been with us for three weeks now, but already her enthusiasm and dedication have brought a lot to the team!

🤿 Rachel had a very first dive this week, and she absolutely loved it. We suspect that Rachel has fish DNA. We feel very grateful for having her with us.

🙏 Rachel’s curiosity and strong sense of ethics are a real asset for a small nonprofit like Rissa. There is no doubt the learning benefits will be reciprocal, and we are looking forward to the next months!

🤩 Sea urchins are indeed amazing 🤩

In Norway, the green sea urchin (on the video) is a native species that has become invasive since the 1970s as a result of overfishing its natural predators.

Once overabundant, urchins overgraze their habitat, turning kelp forests into biological deserts, the « urchin barrens ».

To restore kelp forests, volunteers led by Rissa Citizen Science lower the density of urchins on three sites in Tromsø and Øksfjord.

These volunteers –the Kelpers– keep track of how many urchins they collect or crush while diving. They passed 57,000 urchins since 2023.

Kelp forests grow back naturally after the urchin density is brought down. But of course, maintaining kelp forests requires a constant effort. On the long term, the fish populations must be restored to pre-industrial fishing levels, so that predators keep urchins under control. Sea urchins play a very important role in healthy marine ecosystems.

👉 Join the next kelp restoration event in Tromsø or Øksfjord (go to Rissa’s website/EVENTS).

🤝 @sut_dykk the student diving club in Tromsø is a key partner, renting out wetsuits to many of the snorkelers.

✍️ To start this event, each participant will hand-write a short letter to the Minister for Climate and Environment Andreas Bjelland Eriksen, to support a ban on international commercial trade.

🐻‍❄️ Then, take the stage and tell us your favorite polar bear story!
——
For now, the polar bear is listed on CITES Appendix 2, which means the commercial trade is allowed under certain conditions.

🇳🇴 Norway continues to import polar bears. Between 2012 and 2021, Norway imported 185 polar bear hides from Canada, 144 for commercial purposes, 37 as hunting trophies and 4 for personal use.

In 2028, governments will gather at CITES COP21. Polar bears will only be considered for stronger protection if a country submits a proposal to uplist them to Appendix I, which would ban all international commercial trade. Norway is best placed to submit a proposal to protect polar bears from international commerical trade.

🤿 The Kelpers give a lot of their time to restore kelps forests around Tromsø by lowering the urchin density. And with spectacular success, like along Sørsjetéen, a 200 meter long jetty in the city center.

🐟 But without enough of the natural urchin predators in the ocean, the culling of sea urchins will remain a necessity.

The Kelpers replace —very locally— the natural urchin predators, to allow kelp to thrive. At least there, one can see what a kelp forest may look like in a healthy ocean where fish communities are diverse and abundant.

🤝 Rissa’s effort to restore kelp forests with volunteers (the Kelpers) is part of and supported by the Ocean Green project @oceangreenofficial. Our most direct partner is NIBIO @nibio_no in charge of of Work Package 7 (outreach, citizen science, capacity building).
🤝 Tromsø University @uitnorgesarktiske and @arktiskmuseum are a precious partner for the Telegrafbukta restoration site.

🎥 The footage shows a spotted wollffish (Anarhichas minor) at Polaria @polaria eating an urchin collected by the Kelpers during a kelp restoration event at Sørsjetéen on Sunday 8/3.
This species differs from the Atlantic wolffish (Anarhichas lupus) which is more likely to be found in shallower water, where kelp forests grow.

Leave No Trace, in Ånderdalen National Park
🎦 The documentary is now available on Rissa Citizen Science’s YouTube channel (and on Rissa’s website/blog).

THE PITCH:
🇫🇷 -> 🇳🇴 -> 🇫🇷 Twelve teenagers from Fénelon school (La Rochelle, France) set out on a memorable journey to Northern Norway. Traveling by train and bus to minimize their carbon footprint, they head to Ånderdalen National Park, 300 kilometers north of the Arctic Circle.

🏔️ There, they spend a week immersed in hands-on conservation work, restoring peatbogs and hiking trails, and mapping biodiversity in a fragile and spectacular landscape.

🌲 Combining action, reflection on how humans can coexist with nature, and moments of quiet contemplation in a remote Arctic setting, the project emerges as a compelling example of regenerative travel, ultimately becoming a once-in-a-lifetime adventure for everyone involved.

🤿 Volunteers started restoring the southern side of Sørsjetéen in 2023. Thanks to them, kelp has returned, attracting an impressive marine biodiversity.

Snake pipefish (like most small fishes) needs seaweeds to hide, and these seaweeds have been replaced by urchin barrens in most places along the coast. Liga (@facethewild.underwater) spotted this pipefish among the young blades of what became a kelp forest a few weeks later. Several of her photos are currently displayed in an exhibit along the jetty.

Rissa’s effort to restore kelp forests with volunteers is part of the Ocean Green project (@oceangreenofficial) led by Ava Ocean, and composed of @nibio_no @nivaforskning @akvaplanniva, Across Nature and Hofseth BioCare.

😮 What an evening!

A packed room, a standing ovation at the end for Adam Cruise, the investigative journalist featured in the film (but really for the whole team of Trade Secret).

A remarkable investigative work that lasted for 6 years, the films shows the behind-the-scene of CITES (Convention on International Trade in Endangered Species) and its role in maintaining commercial trade of polar bears skins and trophies.

🇳🇴 Norway plays a very influential role in this trade, being the second importer of polar bear fur and trophies, just behind China.

🙏 ❤️ Many thanks to those who helped promote this memorable event.
Aurora Fokus will donate 40% of the ticket sales to Trade Secret.
Fint Kafé & Bar will give 10% of their sales to Trade Secret (coupons distributed to those attending the screening) which shows the local support for the total protection of polar bears worldwide.

Rissa CS is very happy to have initiated and facilitated this screening, and it was an honor to welcome Dr Adam Cruise, a world-class investigative journalist.

⚠️ Rissa CS is working on a follow-up project on polar bears in Tromsø: reach out if you want to know more, we are looking for 2 or 3 volunteers to join the project.

Thanks to the Kelpers, life is coming back at Telegrafbukta!

These dedicated volunteers have removed over 32,000 sea urchins in this restoration site.

It is a bit early to tell how things will evolve, but we’re taking these new baby seaweeds as an encouragement.

The green sea urchin is an important part of a healthy ocean in Norway. But after overfishing reduced considerably the urchin’s natural predators, the urchin’s population exploded and the Norwegian coast turned into a large urchin barren where only a few species live. Without predators to control their population, urchins overgrazed their habitat.

With support from the Ocean Green project (@oceangreenofficial) we organize events where volunteers join (on land and in the sea) to restore these lost kelp forests.

After restoring a first site (Sørsjetéen) successfully, we started restoring Telegrafbukta in May 2025. Finally the sun is back (we are 350 km north of the Arctic Circle) and the ocean is waking up. The next two months will show how nature responds to our effort 🤞

🤝 @sut_dykk the student diving club has been a key partner, by providing wet suits to many of the snorkelers ❤️. We have been encouraging people to become a SUT member.

🤝 @arktiskmuseum the Arctic university museum has been facilitating the logistics, by letting us put up a tent (where the divers can change) under their roof when the weather was tough. We are also working closely with one of the researchers there.

👉 Everyone is welcome to join the events, and they are free. Check Rissa Citizen Science’s website/EVENTS and sign up!

🤝 Our main research partner in the Ocean Green project is @nibio_no. @nivaforskning and @akvaplanniva are also part of the consortium.

🤝 @arktiskmuseum the Arctic university museum has been facilitating the logistics, by letting us put up a tent (where the divers can change) under their roof when the weather was tough. We are also working closely with one of the researchers there.

👉 Everyone is welcome to join the events, and they are free. Check Rissa Citizen Science’s website/EVENTS and sign up!

🤝 Our main research partner in the Ocean Green project is @nibio_no. @nivaforskning and @akvaplanniva are also part of the consortium.

🥳 The Strandvegen 8 KITTIWAKE HOTELS are back! 🥳

This decision will ease conflicts with residents and workers in the neighborhood, as the hotels will provide alternative nesting sites to the kittiwakes using buildings where they are generally unwanted.

Two large hotels on top of Strandvegen 8 had been removed in 2025 just before the nesting season. The result was catastrophic for the kittiwakes. It was also bad news for people since some pairs relocated to neighboring buildings.

One person even ended up in @bladetnordlys, being fined by the police and with bad publicity for destroying nests on their house during the breeding season. Now kittiwakes can return to the hotels.

The black-legged kittiwake is ENDANGERED on Norway’s Red List and faces a HIGH RISK OF EXTINCTION in Norway.

👉 If you want to support the kittiwake in Tromsø, reach out to us, and become a Kittiwalker!

🙏 This year, the @hurtigruten foundation is supporting our work with kittiwakes in Tromsø.
🙏 @focusnordic is sponsoring us with amazing @kiteoptics_nature binoculars that the most active Kittiwalkers can borrow for free to monitor the kittiwake nests.

Restoring kelp forests in Norway requires to lower the density of sea urchins, which means either harvesting them or crushing them.

Sea urchins are amazing creatures. The green sea urchin is a native species. It has become invasive as a result of overfishing, when its natural predators weren’t enough to keep its population under control. Urchins overgrazed their habitat, and created barrens, ecological deserts.

Sea urchins are often framed as the cause of the disappearance of kelp (and more generally seaweed) forests. Whereas in fact, their over abundance is mainly the consequence of industrial fishing since the 1970s. Urchins are the scapegoat in the story.

Sea urchins are amazing. Learn about them, and you will look at them in a different light ❤️

Today at Sørsjetéen, volunteers sampled sea urchins to measure their mass and diameter. While enjoying waffles and having a good time together 🧇

@pixiepencil inaugurated the first lightning talk, and shared some personal stories about a male wolffish found at 400 m below the surface, and looking after his eggs. It was super interesting and fun to learn about a fish those restoring kelp forests hear so much about. Thank you Jane!

Many thanks to @roelm22 who sampled the sea urchins, to Kane, Thora, Sofia who did all the measurements and to Carina who entered all the values with care.

❤️ A generous supporter is letting us use his underwater drone to allow the volunteers who are not diving to admire the marine life thriving along the jetty: anemones, sponges, soft corals 🪸

🤙 We encourage everyone to become a member of the student diving club @sut_dykk, to join the Tromsø diving community while having access to diving equipment.

🤝 The Ocean Green project @oceangreenofficial is supporting our effort to restore kelp forests with volunteers in Tromsø. Our direct research partner in Work Package 7 is @nibio_no

As part of making tourism more REGENERATIVE in Tromsø, travelers who are exploring Norway onboard @vikingcruises contributed today to the Tromsø Tits research project @tromso_tits.

💡The project aims at better understanding the effect of light pollution in the Arctic on birds. It is led by Dr Tomotani at the Arctic University of Norway @uitnorgesarktiske.

⚠️ Overtourism is a serious problem in Tromsø, with negative impacts on the environment and local communities. It is an extractive industry, which converts nature, a resource that is free and available to all, into financial profits for a few, in ways that are not sustainable.

Regenerative tourism, on the other hand, creates the conditions where travelers are not viewed as consumers of commercial products, but can contribute during their visit to making the destination a better place for nature and the local population.

It’s a win-win system, where travelers experience a destination in ways that are rewarding, fun, and without the guilt that often comes with mass tourism.

🐣 Today, travelers explored an incredibly beautiful forest, in a small group, while being part of a meaningful research project. A hike with a purpose.

A kelp forest is thriving in Tromsø along Sørsjetéen, but only thanks to the volunteers who dive and remove sea urchins regularly.

This small-scale success story brings hope, but it also shows that on the long-term, the ocean needs better protection, and more fish diversity and abundance to keep the sea urchin population under control.

The super abundance of urchins is a consequence of overfishing their natural predators since the 1970s.

The green sea urchins (Strongylocentrus droebachiensis) is the species that dominates. It is a native species in Norway, and it plays a very important role in healthy oceans.

👼 It would be short-sighted to demonize sea urchins, or to frame them as the ones responsible for the disappearance of kelp forests.

🐣 The @tromso_tits project finished the 2025 nesting season with 202 nestboxes on Tromsøya.

Here is a recap about how the nestboxes have been used by great tits, blue tits and pied flycatchers.
The «number of chicks» corresponds to the number of chicks that fledged (those who left the nest).

Additionally, Dr. Tomotani’s team ringed 780 adults & chicks!

💡 One of the goals of the Tromsø Tits project is to better understand the effects of artificial light at night (ALAN) on songbirds, in areas in the Arctic like Tromsø where light pollution is very high.

🤝 @rissa_citizen_science is partnering with Dr Tomotani, making it possible for everyone to take part in her research in the field. This is Rissa’s SONGBIRDS project.

We organize events all year round to check the nestboxes, put up new ones, fill the feeding stations, and raise awareness about light pollution in the Arctic. We are currently building and painting nestboxes, from recycled wood, with volunteers as social events.

Sea urchins are super abundant in Northern Norway, due to decades of overfishing their natural predators. @sararoosvall has found a ways to turn urchins into art by using the pigments naturally present in the shell.

It is a tedious process that starts with selecting the most colorful shells, and those having a similar tone.

Sara uses the green sea urchin (Strongylocentrotus droebachiensis) which can be pink, or purple (yes!). This is a native species in Norway, and it became overwhelmingly dominant after the 1970s. It plays a very important role in a healthy ocean, but can overgraze its own habitat when its population is not controlled by predators.

🎨 Art is a powerful tool to raise awareness, and @rissa_citizen_science was very happy to collaborate with @esn.tromso for this project. We are very grateful to @esn.tromso for covering Sara’s travel costs and for making this workshop possible.

🙏 Many thanks to all the participants, and thumbs up to @sara.natureart for her great teaching skills and inspiring creativity!

🤿 Well done Kelpers!!

🦦Thanks to our team effort, Sørsjetéen remains a refuge for biodiversity, starting with the foundation of coastal marine life: kelp and other seaweed.

Last Sunday was tough! An early start (09:00), minus 12C and some wind. But the spirit was fantastic.

🙏 Thanks everyone, those in the sea, those on land, helping the divers, making waffles, running the citizen science, keeping the log book or just chit-chatting and sharing stories :)

🤝 These community events are made possible thanks to @oceangreenofficial.

🤝 @nibio_no is our direct partner in Work Package 7 of the Ocean Green project.

🙏 @hellyhansen made our freezing day a little cozier by sending fleeces that were used by the volunteers. Thank you @hellyhansen!

From now on, anyone — anywhere in the world — can contribute to our kelp forest restoration effort in Tromsø!

The Urchin Density Challenge takes citizen science to the next level, inviting people around the world to document biodiversity changes in areas where volunteers are restoring kelp forests.

👉 Read our latest post on Rissa’s website/ BLOG, and give it a try!

🤿 At each KELP event, one of our snorkelers takes around thirty photos of a 50×50 cm frame placed randomly on the seabed, both inside and outside the restoration area. These images help us track changes in sea urchin density and biodiversity over time. And this is where you come in! All you need to do is count the sea urchins you can spot inside the frame.

The first step is to download the Rissa’s mobile app from Google Play or the Apple Store. Open the app, select the Urchin Density Challenge, and start counting urchins!

🙏 @oceangreenofficial is supporting this citizen science initiative 🙏

🤝 @arktiskmuseum and @uitnorgesarktiske are close partners of The Urchin Density Challenge, and scientific advisors🤝
