Mosquito Alert and the Marimurtra Botanical Garden continue their collaboration in various experiments related to the tiger mosquito

Marimurtra, due to its climatic characteristics and the great plant biodiversity it contains, requires variable water inputs. All in all, it generates habitats very similar to the natural ones of the tiger mosquito. For this reason, it becomes an ideal place for carrying out Mosquito Alert experiments.
It should be noted that Marimurtra applies treatments to prevent the proliferation of this invasive species with very good results, and yet it is still a very suitable natural laboratory to carry out this type of study.

The following studies are currently being conducted:

1.Study of the dynamics of tiger mosquito populations throughout the season through the deployment of a series of traps to monitor the adult mosquito population in the Garden.
These traps are part of a more extensive network of traps throughout the province of Girona. The aim is to have data on the population dynamics of the mosquito in the province to understand the climatic factors, land uses (urban, garden, urbanization, etc ..) and sociodemographic that determine the abundance of mosquitoes.

2.Study of the population structure of the tiger mosquito in the garden and its survival. Experimentally, it is being studied in the garden how long a tiger mosquito lives and the demographic structure of its populations, this is done by comparing the survival rates of an experimental population born in a laboratory whose age is known, and wild individuals caught in the garden.
The survival study is important because the tiger mosquito is a vector (ie, transmitter) of disease. Therefore, determining the length of time mosquitoes live allows us to better understand the potential for transmission of these diseases.
3.Analysis of the treatments that are being done to control the proliferation of tiger mosquitoes and determine how these treatments affect the mosquito population.
4.Study of the human-mosquito interaction network. The goal is to analyze how many people can be bitten by a tiger mosquito from the genetic study of blood found inside female mosquitoes. Genetics makes it possible to find out if the blood corresponds to one, two or more different people and therefore to know how many different people a female can bite.
It is very interesting to determine what the network of interactions of the tiger mosquito is because there is not much scientific information about it and it will be possible to determine the potential for transmission of the diseases of which the tiger mosquito is a vector.
This pioneering study is done by relating the DNA in the blood in the abdomen of the female mosquito to the DNA of people who donated it to do this study. This way, you can know how many different people the mosquito has bitten and how many times it has bitten the same person.
5.Installing a smart trap. This trap works with artificial intelligence and is able to identify mosquitoes that enter it from the sensors it contains.
With these experiments, the Marimurtra Botanical Garden continues to collaborate with the Mosquito Alert project to better understand the behavior of the tiger mosquito and its impact on the human population. You can find more information about the tiger mosquito in Marimurtra by clicking here.

Agreement with the Vedruna School of Malgrat for a herbarium from the beginning of the 20th century

This herbarium, dated around 1909, has been recently discovered and will allow the presence of certain species of plants in Catalonia to be dated for the first time

Conveni Escola Vedruna Malgrat | Fundació Carl FaustThe Marimurtra Botanical Garden has received on loan a herbarium from the Vedruna School of Malgrat de Mar elaborated between 1909 and 1913 which will allow botanists and experts of the Marimurtra Botanical Garden to study and document the collection of plants collected at the beginning of the 20th century in different towns of the Baix Empordà that it contains. In other words, we can take a trip back in time to rediscover the plants that were in that place a hundred years ago and compare them with the current ones, which will allow us to date the presence of ornamental crop plants in the area and document species found for the first time time in Catalonia. In addition, this natural history collection places in the territory one more sample of the naturalist and botanical work that existed in Catalonia at the beginning of the century.
The herbarium received from the Malgrat de Mar Vedruna School consists of about 400 specimens of the ruderal, riverside, horticultural and ornamental flora of three towns in the Baix Empordà region (Sant Tomàs de Fluvià, Torroella de Fluvià and Vilacolum). It is preserved in very good condition and was prepared by Luis de Pont Adroher, a Girona pharmacist of whom the University of Girona herbarium also preserves some of his specimens.
Funded project
The Francesc Eiximenis 2021 Fund, awarded by the Ramon Muntaner Institute, has selected the study “Two Herbaria from Girona: Botany from Girona at the beginning of the 20th century (1909 to 1939)” presented by botanist Carlos Burguera, botanist curator of the herbarium of Marimurtra Botanical Garden. Precisely, the herbarium received is the first of these two representative herbaria of the Girona flora, which will allow to witness the plant species found in different regions of the province collected during the first half of the 20th century.
While waiting to receive the second herbarium, the Carl Faust Foundation begins the restoration and conservation work of the herbarium to begin its computerization and study.

Marimurtra’s insect hostel

Conversation between Pau Bosch, designer and builder of the insect hostel, and Jordi Fàbregas, Master Gardener of the Marimurtra Botanical Garden

During 2020, the second Marimurtra insect hostel was installed in the Braun-Blanquet lake area, in the 3rd Garden (the first is located right next to the organic garden).
An insect hostel is a typical element of the gardens that fulfills many functions at the same time.
On the one hand, it offers shelter and a space to nest the pollinating insects in the garden and, therefore, it helps those insects that participate in the reproductive function of plants to find a safe and welcoming space to carry out their task. Continuing with biodiversity, it must be said that an insect hostel brings variety and biological richness to a garden precisely because it is designed from the point of view that a garden is much more than its plants, and to understand it, many other important layers must be taken into account: from the soil itself to the animals (insects, amphibians, birds, etc.) that inhabit it. In other words, the insect hostel is also part of the narrative that has led Marimurtra to quit using synthetic chemicals to respect and enhance biodiversity, human, animal and plant health and, ultimately, pave the way towards a world without products that can be harmful to life on the planet.
In the case of the insect hostel at Lake Braun-Blanquet, it can be seen that it contains two different types of spaces: holes and plant elements. The holes are the really interesting part for pollinating insects (solitary bees, etc.) as it offers them a place to nest and lay their eggs. The different plant elements that the hostel contains, on the other hand, serve as shelter for insects that find safety in the insect hostel.
Finally, we must highlight the landscape value of an insect hostel like Marimurtra’s, which becomes an outstanding element of the Botanical Garden, also becoming an aesthetically remarkable piece, with a unique design and made with proximity materials that perfectly integrate with Marimurtra.
We invite you to discover every corner of the insect hostel of the Marimurtra Botanical Garden.

Preparem la planta de temporada amb en Ventura

Des de fa més de 50 anys, els jardiners de Marimurtra preparen anualment la flor de temporada als vivers del Jardí per tal que el visitant sempre trobi les espècies més destacades de cada estació. Aquest procés de preparació és ja una tradició a Marimurtra iniciada pel seu creador, Carl Faust. Això vol dir, que alguna de les llavors que s’estan plantant actualment, descendeixen de les plantades aleshores.

Aquest cicle es duu a terme dues vegades a l’any, i consisteix a recollir la llavor de les flors del Jardí i seleccionar-ne les millors per  guardar-les en pots de vidre per la seva correcta conservació. Quan arriba la temporada de plantació, es prepara el planter amb terra i compost que es prepara a Marimurtra, per poder sembrar-les. Quan ja han crescut, es transplanten a l’interior del Jardí, i quan aquestes plantes tornin a fer flor es torna a repetir el procés.
D’aquesta manera, s’obtenen dos beneficis:

  • L’aprofitament dels recursos que ens dóna la pròpia planta.
  • La visualització del cicle vital de les espècies.

En Ventura Torroella, jardiner del Jardí Botànic Marimurtra, ha estat l’encarregat de preparar la planta de temporada des de fa més de dues dècades i en el següent vídeo ens explica com duu a terme aquest ritual de Marimurtra.

Setmana de la Ciència a Marimurtra

Celebració de la Setmana de la Ciència 2018 al Jardí Botànic Marimurtra

La Fundació Privada Carl Faust organitza jornades de portes obertes i visites guiades amb sistema de taquilla inversa Jardí Botànic Marimurtra en motiu de la Setmana de la Ciència

Com cada any, la Fundació Carl Faust se suma a la Setmana de la Ciència oferint unes jornades de portes obertes que tindran lloc els diumenges vinents 11 i 18 de novembre. Tenen com a objectiu apropar el Jardí Botànic Marimurtra a tots els públics per tal que els visitants puguin gaudir de la riquesa del seu patrimoni botànic, arquitectònic, paisatgístic i humà.

En els seus estatuts s’hi estableixen els seus objectius fundacionals que són: “la protecció i el foment dels estudis de biologia mediterrània, especialment en botànica, […] cercant la cooperació i les relacions internacionals en benefici, tot plegat, de la recerca i de la divulgació científiques.”

La Fundació Carl Faust va ser mereixedora el 2009 de la Creu de Sant Jordi i el Jardí Botànic Marimurtra està classificat com a Bé Cultural d’Interès Nacional per la Generalitat de Catalunya.

Additions to Marimurtra’s cycad collection

Marimurtra Botanical Garden is expanding its collection of cycads thanks to collaborators Javier Garcia Pua and Simon Lavaud

The recent exchange with Javier Garcia Púa has offered Marimurtra the opportunity to acquire a very valuable specimen for the garden’s collection of cycads. A hybrid of the palms Jubaea chilensis and Butia odorata was exchanged for the cycad Encephalartos lebomboensis, a native of South Africa like most cycads. This species is in danger of extinction and is at risk of disappearing in its wild state.

Two specimens of Dioon merolae and one Macrozamia mountperriensis were also purchased. With the help of cycad specialist Simon Lavaud, these specimens have been planted in different strategic areas of the Garden.

Dioon merolae is also in danger of extinction. While the two new specimens are relatively young, specimens more than 500 years old have been found. You can determine their age by the length of the trunk, or stem. To know the sex of the plant, you must await its cone-shaped inflorescence. Males and females look different.

These species add value to the collection of cycads, which continues to increase in variety and number of species, with the aim of guaranteeing the survival of this genus, as many cycad species are in danger of extinction. The collection at Marimurtra is fast becoming one of the most important collections of cycad in Europe, with acquisition of new species included in the garden’s budget.

Innovating the detection of Red Palm Weevils

As always at Marimurtra, we work to ensure sustainability of the environment. Recently, an innovative system created by IoTrees, has been implemented to detect Red Palm Weevils (Rhynchophorus ferrugineus) which attack our palm trees. The new system consists of seismic sensors that are placed in the palm and detect the sounds weevils make as they chew their way towards the growing point or ‘heart’ of the palm. (Unlike other plants, palms have only one growing point, and if that is destroyed the palm cannot re-grow, and it dies).

marimurtraThis small insect is the culprit behind the deaths of thousands of palm trees every year in our country, and milions worldwide. The weevil has become a real plague that affects a large number of Communities in Spain, especially those located in coastal areas, and its pace of expansion has been unstoppable, and seemingly as well, the damage caused to the palm trees. The larva is the life stage that really causes the greatest damage to the palm trees. After hatching, they feed on the soft inner tissues and new growth of the tree, and it is at this moment that death begins for the palm.
In the Marimurtra Botanical Garden, a total of 4 palm trees have died due to this insect and, in order to avoid future attacks, an innovative and environmentally friendly system has been sought to help identify sufficiently in advance the specimens that suffer from this plague.

The sensors have incorporated a system that detects seismic movements. When they detect a match for a sound wave pattern coinciding with the sound of a weevil biting the palm stipule, it sends a signal to a mobile device, warning that that palm is being attacked. It is able to detect a larva of only 1 cm in length, which allows a very early detection of the attack to guarantee the survival of the specimen.

marimurtraA seismic sensor is placed in the stipule of the palm tree. In this way, it is able to detect all movements that occur in the palm tree. Its system of detection of the weevils is very effective and innovative, since it excludes the natural movements produced by the wind or the rain, but zeroes in on the movement and the vibration of the weevils chewing the palm.

In this way, the death of any specimen can be prevented by early detection. Once detected, we provide a treatment with plant extracts to eradicate the pest before it is too late. In Marimurtra, no chemicals are used and the treatment is done with Neem (Azadirachta indica) vegetable oil.

The most awaited bloom of the year in the Marimurtra Botanical Garden of the Costa Brava is now in full glory

Drossanthemum floribundum carpets the stone blocks bordering Marimurtra’s ‘Steps of Epicurus’ with a waterfall of pink.

The 81 Steps of Epicurus are one of the most significant constructions of Marimurtra, structured in 9 different levels of 9 steps each, the stairway is famed for tits majesty, for the stunning views provided, and for the color offered by the Drosanthemum during Spring. Due to its visual delight, Epicurus’ Steps during full flower has become one of the most representative images of the botanical garden on the Costa Brava.
Escales Epicur Marimurtra
Also known by the common name ‘Midday Flower’ or Queen’s Hair, this is a classic species because of the multitude of pink flowers it provides during its ephemeral flowering. Native to South Africa, and thus well adapted to wet winters and dry summers, it is commonly used in Meditarranean gardening as a living carpet. Drosanthemum’s leaves are covered with water cells and this makes them glisten as if dew-covered or freshly watered, the flowers are a pale pink color and unfortunately its flowering lasts approximately 3 weeks, between March and June. In addition, they are a great source of pollen collection by the pollinating bees of the Garden.
Drosanthemum Marimurtra

They are given the common name of ‘Midday Flower’, since they require a lot of sunlight to open up. Therefore, sunny days are ideal to enjoy this species, and especially when the sun is in its most perpendicular to the Earth, at noon. On cloudy and rainy days its flowers remain closed. The genus name Drosanthemum is derived from the Greek for dew, drosos, and flower, anthos, referring to the glittering appearance of many species. Their abundant flowering inspired another common name, ‘Queen’s Hair’, while the scientific name ‘floribundum’ is from the Latin for “many flowered”.

In addition to their botanical content interest, the Epicurus’ Steps mark the promise of love between two people. In the Marimurtra Botanical Garden weddings are held, and the spectacular descent of the bride takes place on these majestic stairs. It is a unique moment and the beginning of the path to the exclusive ceremony at the Temple of Linnaeus.

Water in Marimurtra Botanical Garden

Marimrutra Botanical Garden benefits from new projects themed around the importance and benefits of water

Water is an element of nature, integral to natural ecosystems, fundamental for reproducing life on the planet. It is indispensable in making possible the development of biological processes.

At Marimurtra Botanical Garden, we are very aware of both the need and importance of water: not only for the hydration and nutrients that it offers to the Garden, but also in a visual and sensory sense. We have begun a series of changes in our water systems and devices.
On the operational side, the Garden’s rainwater catchment system has been rehabilitated to optimize our use of water. Recovering the knowledge and practices of our ancestors, using basic materials and tools, a mechanism has been created to keep the rainwater and the underground water from being lost, we use this very efficiently, to the last drop.

La mina del Jardí Botànic Marimurtra
Botanical Garden Marimurtra’s mine

Therefore, at a time when there is an increasing scarcity of water resources, the improved efficiency achieved thanks to the collection system will provide significant environmental and economic benefits. Our irrigation supplies will gain from the 1.402.373,4 liters of collected water per year.

On the experiential side, we recognize that ‘water is life’ and the sounds produced by its movement helps to create a healing sensation of peace and calm for the visitor. The sources of the Garden are an essential element in this process, especially at the landscape level.

Marimurtra will create a new space of peace and relaxation through the fountains installed in the third garden: with the addition of three pumps, water will be able to circulate throughout the space. This will create the relaxing atmosphere, while being on-hand for some irrigation. By circulating continuously, stagnation is prevented, and mosquitoes are prevented.

Recognizing the importance of water for sustainability of the environment, Marimurtra Botanical Garden is organizing a photo contest on social networks (Facebook, Twitter or Instagram) in which the main theme is water in Marimurtra.

Express yourself with the hashtags #h2omarimurtra and #marimurtra and share with us your creative perception of the water inside the garden. The contest will be active until Sunday, March 25th at 11:59 p.m. The 5 most original photographs will be selected, of which 4 finalists will be awarded and one winner. The winner can enjoy an annual subscription to visit the Marimurtra Botanical Garden, a breakfast for two in the garden’s café area and a gift from a selction of Km0 craft products from Marimurtra.

Liven up and do not let your opportunity escape!

Imatge de l’entrada al Jardí Botànic Marimurtra l’estiu de 2017

La visita al Jardí Botànic Marimurtra, un dels dos únics de Catalunya i l’únic de la Costa Brava, continua presentant unes dades d’estacionalitat molt elevada, tal i com indica la dada de que el 83% dels visitants van anar a Marimurtra en el període de primavera i estiu (abril-setembre) mentre que nomes el 17% ho van fer la resta de mesos. En aquest sentit, la Fundació Carl Faust ha preparat un seguit d’accions per fer més atractiva la visita en els mesos que cauen fora de al temporada alta. Aquestes accions estan pensades també per promoure la vessant pedagògica de Marimurtra, i consisteixen en posar a disposició dels visitants uns materials lúdics i didàctics per fer en família i que es poden descarregar gratuïtament del web del Jardí Botànic

La Fundació Carl Faust, propietària i gestora del Jardí Botànic Marimurtra, valora molt positivament aquestes xifres en un context de recuperació del turisme a Catalunya i de la Costa Brava en particular. També en la revitalització d’un interès pels paratges més icònics i significatius de casa nostra, entre els quals destaca Marimurtra, una proposta lúdica i cultural amb un gran interès botànic i paisatgístic.

La Fundació Carl Faust és una fundació privada sense ànim de lucre que el 2009 va rebre la Creu de Sant Jordi de la Generalitat de Catalunya. El Jardí Botànic Marimurtra està classificat com a Bé Cultural d’Interès Nacional per la Generalitat de Catalunya.
