New Issues: Scientific stamps (France, Åland, Netherlands, Croatia, Spain)

In the last few weeks there have been a few new European issues with a scientific theme. I am quite interested in science and I have decided to review all of them together partly because there is a shared theme and also because it is a really good thing to celebrate science. France: 400th Anniversary of the National Museum of Natural History, Botanical Garden

The Jardin des Plantes, the botanical garden that is part of the National Museum of Natural History (Muséum national d’Histoire naturelle) in Paris, celebrated its 400th anniversary this year.

The WOPA website tells us something about its history:

"At the urging of his physicians, Louis XIII established a Royal Garden of Medicinal Plants in 1626. The institution gradually expanded its scope of natural history studies, relying on talented individuals. In the 18th century, the Count of Buffon, superintendent for nearly 50 years, tirelessly expanded the collections brought back from explorations. Surrounded by leading scientists of his time, he contributed to the prestige of the royal garden and doubled its size. During the French Revolution, the institution reinvented itself: the National Museum of Natural History was created in 1793 by decree of the National Convention. Until the mid-19th century, it reigned supreme throughout Europe, without any real rival.

"In the 20th century, it expanded beyond the Jardin des Plantes: botanical gardens, marine stations, archaeological sites, and zoological reserves broadened its scope of activities across France. The Paris Zoological Park, the Musée de l’Homme (Museum of Man), and the Grande Galerie de l’Évolution (Great Gallery of Evolution) were among its notable additions. The 21st century began with a thorough reform of the institution's organization, followed by a major renovation.

"Today, drawing on its sites, collections, research, and teaching, the Museum is a leading scientific center. A French and global expert on issues related to nature protection, he is committed on a daily basis to bringing the voice of nature to the widest possible audience."

Design quality: This is simple, but it works. The museum building gives the stamp a sense of place, while the plants in front are what catch my eye first. The green leaves stand out against the mostly white background without making it feel crowded. 7/10 Theme and subject choice: Four hundred years is a huge milestone for a place with such a long history of studying nature. The Jardin des Plantes is the historic heart of France’s National Museum of Natural History, so it feels like a really good choice for a French stamp. 9/10 Cultural and historical relevance: This is much more than a nice garden. Its history goes back to a royal garden for medicinal plants, and it has become an important place for science, learning and visitors. 10/10 Innovation and creativity: I like how the plants overlap the building. It makes the garden feel alive instead of just showing a picture of a museum. It’s a clever touch, although the overall design is still quite traditional. 6/10 Collectability: I can see this appealing to people who collect stamps about plants, gardens, science or French history. It has a clear subject and a design that is pleasant to look at. 7/10 Personal appeal: The theme is the main reason I like it, but the design helps too. The museum is there, yet the plants get most of the attention, which feels right for a stamp celebrating the Jardin des Plantes. 8/10 Overall Score: 47/60

France: Underwater Flora

Here is another scientific stamp from France, this time celebrating underwater flora. La Poste helpfully tells us something about the subject and why it is so important: "Underwater flora is revealed at low tide or while diving: marine plants and especially green, red, or brown algae, sometimes tiny and delicate, sometimes majestic. They then rise up like underwater trees. A careful look, a touch, is all it takes to marvel at their diversity, their colors, their beauty. Each one is a veritable oxygen factory: together, they capture solar energy to nourish the food chain.

"On the tidal coast, species surprisingly tolerant of daily exposure cycles, such as wrack (Fucus), provide refuge for an entire animal community while awaiting the incoming tide. In the depths, kelp forests form veritable forests, offering shelter and sustenance to numerous species of fish, crabs, starfish, anemones, and other animals. Their smooth, undulating fronds form a canopy that filters dim light, ideal for the growth of other algae adapted to this "undergrowth." In other habitats, marine plants form large, equally productive seagrass meadows that serve as nurseries for numerous fish and shelter seahorses.

"This elegant, powerful, and fragile flora remains a world to be explored, opening up many possibilities. Will we know how to care for it? The delicate balance of life on our planet depends on it." Design quality: The green and pink forms look beautiful, but they also give the stamp a scientific feel. We see two sides of a "specimen" placed side by side - or is it two different specimens? The sharp line down the middle makes you stop and compare them. At first it looks like a view above and below the water, but both sides show bubbles if you look closely, so the split draws attention to the variety of marine life. 9/10

Theme and subject choice: Underwater flora is an excellent choice. Stamps often show sea creatures, but the plants and algae that help support them deserve attention too. 10/10

Cultural and historical relevance: There isn’t an obvious anniversary or historical event here. The relevance is in what this marine life does: it produces oxygen and provides food and shelter for other species. 8/10

Innovation and creativity: The split composition is my favourite part. It makes the stamp feel like an illustration you could study, while the bright colours keep it exciting. Showing two contrasting forms makes you notice that underwater flora isn’t all one thing, which is an important part of the message. 10/10

Collectability: Science might be a more specialised collecting theme, but nature and marine life are popular. The unusual design could also catch the eye of someone who wasn’t looking for a science stamp. 7/10

Personal appeal: I think this is a brilliant stamp. It looks striking, teaches me something just by making me look more closely, and celebrates a part of the ocean that’s easy to overlook. 9/10 Overall score: 53/60

Åland: Microalgae

Next we have an issue from Åland about microalgae. I will let the WOPA website tell you more: "As the most important marine primary producers, microalgae form the foundation of the food chain. Free-floating algae are called phytoplankton, and they produce nearly half of the Earth’s oxygen.

"The stamp features Chaetoceros wighamii, photographed in material found in the inlet of Inre Verkviken, Saltvik, Åland. This yellow-brown diatom forms chains of cells and long bristles which reduce sinking and grazing of zooplankton. The stamp sheet includes more microalgae.

"'Microalgae exhibit remarkable diversity in shapes and colours. Their movements are also fascinating: ultra-fast jumps, rotating or gliding. The Baltic Sea hosts several thousand species,' says Tore Lindholm, who has studied algae in the Baltic Sea. His images form the foundation of the stamp issue." Design quality: The microscope photography is amazing. The stamps repeat one tiny chain of algae across the top and bottom, while the space between them shows different organisms in circular close-ups. It feels a bit like looking through a microscope and then turning the page of a scientific notebook. The arrangement makes the whole sheet more interesting than the individual stamps alone. 9/10

Theme and subject choice: Science doesn’t get enough attention on stamps, and microalgae are a brilliant subject. These images come from research in Åland waters, so the theme is connected to the place issuing them. 9/10

Cultural and historical relevance: Researcher Tore Lindholm has studied algae in Åland waters for more than 50 years, which gives this a strong local link. And it feels slightly ridiculous to ask whether microalgae are historically relevant as they’ve been part of life on Earth for millions of years! 8/10

Innovation and creativity: Using real microscope images is a great idea, but the sheet’s layout is what makes it special. The repeated stamp image gives it a clear pattern, and the different shapes in the middle reveal how much variety is hidden in a drop of water. 8/10

Collectability: I think nature collectors will notice this, even if science is a more specialised theme. I’d like to own the whole sheet because the layout is part of its appeal, but the price could be an issue - £32.70 is a lot to spend on a minisheet. 6/10

Personal appeal: I love the theme and how cleverly it has been presented. It makes something almost invisible look fascinating. The price would make me think twice, but it’s one of the most memorable stamp sheets I’ve seen. 8/10 Overall score: 48/60

Netherlands: Underwater Life, Saba

This is part of the "Experience Nature: Saba" series, which so far has included birds and butterflies. This issue celebrates the 1,300-hectare Saba National Marine Park, which is home to many fish and coral species. Saba is part of the Leeward Islands and has a very rich underwater life. Saba has been designated as a Hope Spot, which means the area is recognised as scientifically critical to the health of the ocean.

Design quality: The clear blue water makes the colourful sea creatures stand out, and I like how the coral continues behind all three stamps. It makes them feel like part of one underwater scene. The illustrations are lovely, although the sheet is more attractive than any one stamp on its own. 7/10

Theme and subject choice: Saba’s underwater life is a great subject. The island has a marine park full of fish and coral so there is plenty to show and it gives people a glimpse of a part of the Netherlands they may know very little about. 9/10

Cultural and historical relevance: This has a genuine connection to Saba rather than just being a pretty sea-life theme. Its marine environment is part of what makes the island special, and the nearby Saba Bank is recognised for its biodiversity. It's clearly a scientifically important place. 9/10

Innovation and creativity: Putting the three stamps into a larger reef scene is a nice idea. But the stamps themselves are fairly ordinary pictures of sea creatures, so the design doesn’t surprise me as much as some of the other underwater issues I’ve seen or the other issues in the "Experiencing Nature: Saba" series. 6/10

Collectability: This should appeal to collectors of marine life, nature and Caribbean themes. 7/10

Personal appeal: I like the subject and the colours. It's a good looking sheet, but it doesn't quite live up to the amazing sheets we've already had in this series (birds and butterflies). 6/10 Overall score: 44/60

Croatia: Water management

This stamp celebrates 150 years of organised water management in Croatia. That doesn't sounds very exciting, does it? However, Hrvatska pošta has asked Zoran Đuroković, the Director General of Croatian Waters, to tell us a bit more. Maybe he can change your mind? "Water management has always been inextricably linked to the survival and development of the Croatian people. This is evidenced by the establishment of the Society for the Regulation of the Vuka River on 7 September 1876, headed by Bishop Josip Juraj Strossmayer - a great visionary, statesman and champion of progress. Ever since, thanks to the work of many generations of engineers, experts and employees, the Croatian water management sector has become one of the key drivers of development in harmony with nature and the needs of society and has been recognized beyond the borders of the Republic of Croatia as an example of successful, sustainable and responsible management of one of the world’s most valuable natural resources water.

"At a time when the effects of climate change are becoming increasingly pronounced and society’s needs are growing, Croatian Waters (Hrvatske vode), in cooperation with the relevant ministry and their partners, implement numerous infrastructure projects financed with national and European funds... The results confirm that sustainability, responsibility and partnership form the foundation of successful water management. "For 150 years, cooperation with state institutions, local and regional self government units, the scientific community, the business sector and many other partners has helped build a system based on expertise, trust, knowledge sharing and shared efforts to find solutions to the challenges of today and tomorrow.

"Today, Croatia’s water management system ranks among modern, internationally recognized water management systems. This achievement brings with it a responsibility to continue managing water resources responsibly and work together to build a sustainable future for generations to come." Perhaps that still doesn't sound exciting, but it explains why water management is so important. It isn't just about science, but "survival and development". It's also about planning for a sustainable future. Design quality: The photograph is beautiful. The clear water and bright leaves make me want to look closely, and the green and blue colours suit the subject perfectly. I also like that the water takes up most of the stamp: it makes the theme obvious without needing a diagram. it also shows how beautiful and how important water is. 8/10

Theme and subject choice: Water management is a really unusual subject for a stamp, which is part of why I like it. It’s something people depend on every day but probably don’t think about much. The anniversary marks 150 years since a society for regulating Croatia’s River Vuka was founded in 1876. 8/10

Cultural and historical relevance: This is a specific part of Croatian history, and managing water might seem boring but it really matters. The stamp does a good job of showing why water is worth caring about, even though the image doesn’t tell you much about what happened 150 years ago. 8/10

Innovation and creativity: Choosing such a calm nature photograph for a subject that sounds quite technical is a good decision. It makes the stamp appealing, although the design itself is quite simple and uses a nice photograph to make its points. 6/10

Collectability: Not many collectors have thematic collections about water management. But the nature image could attract collectors. It’s a lovely stamp, but the anniversary is quite specialised, so I’m not sure it would stand out to everyone. 6/10

Personal appeal: I like that this stamp makes an unexpected subject look interesting! 7/10 Overall score: 43/60

Spain: Geomineral Museum

Madrid's Geomineral Museum is celebrating its 100th anniversary, so why not issue a special stamp? The museum is "a scientific, educational, and heritage-focused project dedicated to preserving and sharing geological richness". The stamp shows a view of one of the rooms in the museum, along with a specimen of Australian banded iron formation—one of the collection's oldest rocks, formed 3.5 billion years ago.

Design quality: I love how the stamp shows both the museum and something you can find inside it. The photograph makes the room look warm and inviting, while the colourful bands in the rock catch your eye straight away. It gives you two reasons to stop and look. 9/10

Theme and subject choice: A geology museum is an excellent choice. Rocks and minerals might sound ordinary until you see what they can tell us about Earth’s past. Celebrating the museum’s 100th anniversary is also important. 9/10

Cultural and historical relevance: This is an important Spanish museum with a century of history, and its collections help preserve and explain geological heritage. The building itself is part of the appeal. The rock shown on the stamp is an Australian banded iron specimen formed about 3.5 billion years ago, which makes the contrast between human history (and the museum's 100 years!) and Earth’s much longer history even more impressive. 9/10

Innovation and creativity: Dividing the stamp into two sections works really well with the museum on one side and a close view of a specimen on the other. It feels like seeing the place and then taking a closer look at what it holds. It’s a clever layout, even if the idea itself isn’t completely new. 7/10

Collectability: Geology may be a smaller collecting theme, but there are definitely people who look for stamps showing rocks, minerals and gemstones. Museum and science collectors could enjoy this one too. 7/10

Personal appeal: I really like it. The room makes me want to visit, and the striped rock makes me want to know more. That’s exactly what I’d hope a museum stamp would do. 9/10 Overall score: 50/60
