The Carl Faust Foundation was created in 1951 by the creator of the Marimurtra Botanical Garden, Carl Faust, with the aim of continuing his work. Among its founding objectives are “…the protection and promotion of Mediterranean biology studies, especially in botany […] seeking cooperation and international relations for the benefit, all of this, of scientific research and dissemination .. .”.

2023 report on the monitoring of birds in the Marimurtra Botanical Garden

The report made by the environmental consultant Pere Alzina i Bilbeny in 2023 on the ornithological monitoring in the Marimurtra Botanical Garden, in Blanes, presents detailed data on the species of birds that inhabit or visit this natural space. With an area of 16 hectares and a location between the Mediterranean Sea, forests and urban areas, the botanical garden is home to a rich variety of birds.

During the four visits carried out throughout the year 2023, a total of 35 species of birds were identified, with a special emphasis on nesting species. Several categories of nesting probability have been recorded, ranging from possible to certain, including species such as the Great-breasted Tern, the Black-breasted Tern and the Heron.

The document highlights the presence of 30 species that show signs of reproduction, among which the blue tern, the tudon and the crayfish stand out. The importance of protecting the environment and the species present is highlighted, with the aim of maintaining biological diversity.

In addition, Pere underlines Marimurtra’s involvement in environmentally sustainable practices, such as the cessation of the use of biocides and chemical fertilizers, and actions to promote ornithological fauna and their habitats.

This report contributes to a better understanding of the dynamics and richness of the ancestral fauna of the Marimurtra Botanical Garden, highlighting its importance as a space for conservation and scientific research in the context of international botanical gardens.

The Marimurtra Botanical Garden has carried out the fertilization of the Encephalartos natalensis

On Sunday, December 14th, there was an exceptional event in Marimurtra: the fertilization of the two female cones of Encephalartos natalensis. The history of cicadas goes back more than 200 million years, they are prehistoric plants and in fact, they coexisted with dinosaurs. Specifically, the species Encephalartos natalensis belongs to the Zamiaceae family and forms a fundamental part of the garden’s botanical collection. The vast majority of leafhoppers are seriously threatened in their natural habitats, adding a crucial component to the importance of this event, for its significance in terms of plant conservation.

The specimen of Encephalartos natalensis from Marimurtra is female and has produced two cones, the reproductive structures of these prehistoric gymnosperms. One of the cones has been fertilized with Encephalartos longifolius pollen, thanks to the collaboration of cicada expert Simon Lavaud from France. Simultaneously, the other cone has been fertilized with pollen from Encephalartos horridus, a species belonging to the Marimurtra Botanical Garden.
The pollination technique, carried out dry without the use of water, closely emulates natural conditions. Using an air bulb, the precise introduction of pollen into the cones has been achieved, a practice that mimics how this fertilization would happen in the wild, thanks to the role of insects.

The prospect of developing two hybrids from this fertilization is exciting, although it will take almost a year and a half to determine the success of this initiative. The scales of the cones close after allowing pollination, protecting the ovules inside as they mature into seeds. In approximately 6 months, they will have done so and will be collected. Another six to eight months of waiting will still be required before they can be sown and their viability checked, anticipating a promising spring of 2025 to know the fate of these unique hybrids.

The Nomad Blackboards Project, Marimurtra’s mobile blackboards

Welcome to “The Nomad Blackboards Project” at the Marimurtra Botanical Garden—an innovative initiative aimed at highlighting specific aspects of the Garden through the lens of science. This scientific outreach project allows for the dissemination of certain species, botanical concepts, notable specimens, or prominent locations within Marimurtra in an educational manner, using a flexible format.

“The Nomad Blackboards Project” consists of placing boards with significant content along the Garden, starting with a few boards and the plan to increase their number over time. We seek to integrate scientific knowledge with the natural beauty that surrounds us, without excessively altering the visual aspect of the Garden, offering a captivating experience for visitors.

The specific objectives of the project are to facilitate scientific education, highlight the importance of biodiversity, foster curiosity, and forge meaningful connections between visitors and the natural world. This initiative uses a flexible system that allows for periodic updates and content renewal, ensuring that the project remains dynamic, fresh, and relevant over time.

Each blackboard features a QR code—an interactive gateway to additional online information. By scanning the QR code, you’ll access supplemental knowledge, deepening your understanding of the scientific marvels and natural beauty that surround you.

Explore our online content to find not only more information but also, in some cases, scientific studies conducted on the highlighted topics. Join us on this scientific exploration as we use blackboards to present valuable information, share research findings, and create connections between the enchanting world of the Botanical Garden and the fascinating realms of science.

This project has been undertaken in collaboration with European volunteers, enriching the educational experience not only for our visitors but also for the volunteers themselves. Their dedication and contribution have played a vital role in bringing this project to life, fostering a vibrant exchange of ideas and perspectives. We extend our heartfelt gratitude to these volunteers, whose involvement has added a layer of depth and diversity to “The Nomad Blackboard Project.”

Science Week 2023 at the Marimurtra Botanical Garden

Science Week 2021 in Marimurtra

Over the last two weekends, there have been a lot of science-related activities at the Marimurtra Botanical Garden.

Setmana de la Ciència 2021 | Jardí Botànic Marimurtra

On November 12 and 13 we had the presence of the illustrious botanist Francis Hallé who gave two lectures (“The intelligence of plants” and “The architecture of trees”) and a practical drawing workshop based in the models of arboreal architecture that he himself has defined over more than 50 years of profession.

Its presence in Marimurtra responds, precisely, to the acts of homage to the half century of dedication to botany that Sello Arboleda wants to put in value through the visit to different points of botanical interest, the first of which has been the Garden Marimurtra Botanist.

A new edition of ‘Marimurtra + Científic’ was held on November 20, a one-morning activity in which some of the most important scientific activities of the Marimurtra Botanical Garden are presented. This year has focused on volunteer programs, plant extracts, herbarium, seed bank and the Mosquito Alert project. About twenty people attended this activity which combined the exhibition parts with the practices. In other words, in addition to learning about the different initiatives, it was also possible to make a small herbarium, practice the choice of seeds and get to know first hand the spaces where the natural extracts that make up the Marimurtra Botanical Garden are made.
Finally, on November 21, there was a free guided tour on scientific topics entitled ‘The biodiversity of Marimurtra’. This visit, lasting more than an hour, was designed to provide information on the main aspects of environmental management in Marimurtra. The more than 20 participants who were part of it were able to get to know first hand the programs for the production of plant extracts, the production of compost and natural fertilizer, the inventories of birds and insects, etc.

Once again, the Marimurtra Botanical Garden has taken part in Science Week, offering its visitors the opportunity to enjoy an enriching, scientific and fun experience.

  • Activitats Escola | Jardí Botànic Marimurtra


Botanical gardens, as museums and science centers, have the basic function of reaching both the general public and experts, and it is crucial that they reach students in schools. The museographic strategy includes teaching and dissemination actions, which are defined from the contents generated by botanical research, conservation and, in the case of Marimurtra, its collection of more than 4000 plant species.

Marimurtra returns to the sea to raise awareness of botanical biodiversity with the Botanical Snorkel

Marimurtra, un Jardí Botànic que des del seu inici ha estat connectat amb el mar, torna a apostar un any més per l’snorkel botànic, una activitat que ofereix als seus visitants una experiència que va més enllà de descobrir les més de 3500 espècies vegetals que es troben a l’interior del Jardí.
Amb l’snorkel botànic, els participants s’endinsen al meravellós món submarí on descobreixen que la biodiversitat vegetal no acaba als penya-segats i que la vida vegetal continua exuberant al medi marí.
En aquest indret de la Mediterrània, s’hi troben una gran quantitat d’espècies d’algues diferents, que constitueixen la base d’un ecosistema ric i divers que permeten que moltes altres espècies (tant animals com vegetals) tinguin unes condicions molt favorables per viure-hi. Tota aquesta biodiversitat forma un paisatge submarí ple de colors i vida, que es poden observar de la mà de guies d’snorkel experts en biologia marina. Amb l’Snrokel Botànic de Marimurtra es podran distingir les algues, classifica-les i entendre l’extraordinari valor que tenen per l’ecosistema.
