LIFE4FIR at the 116th Congress of the Italian Botanical Society (online) – 8-10 September 2021

The team of CNR-IPSP presented the LIFE4FIR project during the 116th Congress of the Italian Botanical Society, held online from 8 to 10 September 2021.

CNR prepared an abstract titled “Identification and removal of exotic fir trees for in situ preservation of Abies nebrodensis – Rosario Schicchi, Filippo Amato, Giuseppe Di Noto, Anna Geraci, Gaetano La Placa, Stefano Secci, Roberto Danti” and presented a video for disseminating the contents of the LIFE4FIR project to the scientific audience of the event.

LIFE4FIR at the XIII Italian Conference on Biodiversity (online) – 7-9 September 2021

The team of CNR-IPSP presented the LIFE4FIR project during the XIII Italian Conference on Biodiversity, held online from 7 to 9 September 2021.

This event represented an important opportunity to disseminate to a specialised audience the objectives, activities and expected results of the LIFE4FIR project: LIFE4FIR could represent a virtuous model to be replicated for the protection of other endangered species.

 

Below are the recordings of the two speeches held by Dr. Roberto Danti and Dr. Waed Tarraf, who presented the LIFE4FIR project and related activities.

LIFE4FIR and the Abies Nebrodensis protagonists of the event organized for the FAI Days – 6 June 2021

On Sunday 6 June 2021, as part of the Giornate FAI di primavera, an event dedicated to the Madonie Fir entitled ’Abies nebrodensis, un albero prezioso’ (Abies nebrodensis, a precious tree) was organized.

An excursion to the natural population was led by Prof. Rosario Schicchi of UNIPA and by Dr. Peppuccio Bonomo, executive of the Madonie Park Authority who illustrated the activities and objectives of the Life4fir project to the numerous participants.

The day allowed the exchange of experiences and information between the Life4fir project and the European Network of Geoparks of which the Madonie Regional Park is part.

Summer update of the progress of the LIFE4FIR project

Germination of seedlings in the nursery

The seedlings obtained from the controlled crosses carried out in spring of 2020 have recently germinated and are growing at the ‘Piano Noce’ forest nursery. The development of the seedlings is constantly monitored by UNIPA researchers and DRSRT technicians. These plants will be used to create new plantations in the reforestation and re-diffusion plots identified for the species.

 

 

The system of fences to protect the Abies Nebrodensis is under construction

The technicians and workers of the DRSRT are engaged in setting up the new fencing system, to replace the old, deteriorated fences. The new fences are higher than the previous ones and surround a wider area around the trees of the natural population, allowing to protect the recently surveyed natural regeneration from wild herbivores and anthropogenic pressure.

 

 

 

LIFE4FIR meets the Mayor of Polizzi Generosa – 25 May 2021

On May 25 2021, the Life4fir project delegates met the Mayor of Polizzi Generosa, Gandolfo Librizzi, to define the matter related to the management of the cryobank under construction at the premises of the Abies Nebrodensis Museum, located in the Town Hall.

Progress meeting for the 18th months of the LIFE4FIR project – 25-26 May 2021

The progress meeting of the Life4fir project was held on 25-26 May 2021 at the headquarters of the Ente Parco delle Madonie in Petralia Sottana (PA).

All the beneficiaries of the project  participated the meeting, aimed at evaluating the progress of the technical activities and dissemination events and at updating of financial matters of the project which is approaching the middle of its course (2019-2021).

 

LIFE4FIR for the World Environment Day – 5 May 2021

On Saturday 5th May, the ‘Germogli in Città’ event was organized in Piazza del Duomo in Messina to celebrate the World Environment Day. On this occasion, the Ente Parco delle Madonie prepared a space for the presentation and promotion of the Life4fir project, through the distribution of gadgets, brochures, hats, pencils and the assignment of some young plants of Abies nebrodensis delivered directly by the president of the Park Authority, Dr. Angelo Merlino.

Update on the action A 1.4 “Seed conservation at low temperature (-18°C), application of cryopreservation protocols”

The LIFE4FIR project is currently working on the project action A 1.4 ‘Seed conservation at low temperature (-18 ° C), application of cryopreservation protocols’.

The activities relate the developing of techniques for the conservation at low temperatures of seeds, pollen, isolated embryos and lines of embryogenic callus of Abies nebrodensis. These activities are functional to the implementation of the sperm bank and cryobank.

 

X-ray screening of seeds.

The vain seed problem is the main obstacle in the germination of Abies nebrodiensis seeds. X-ray analysis is a technique developed by IBE-CNR for the rapid selection of seeds with embryo and empty seeds of Abies nebrodensis (Figure 1). This procedure represents a mass screening of the seeds to be used for germination tests or to be stored at -18 ° C.

Prove di germinazione e coltura

In vitro germination tests of seeds stored at -18 ° C and embryos extracted from mature seeds and kept in a refrigerator (4 ° C) were carried out at the CNR-IBE and Unipa-Saaf laboratories, placing the isolated embryos on filter paper and then on different culture substrates (Figures 4,5 and 6).

Figure 6. Germination and in vitro development of Abies nebrodensis embryos

 

In vitro culture tests of immature embryos isolated from cones collected in July are underway at the two laboratories, in order to obtain direct or indirect embryogenesis. The embryogenic callus, obtained from the excision of the embryos extracted from the seeds of the immature cones from plants 6, 8, 10, 15, 16 and 27 shows a rather slow growth. Various culture media containing different basic salts and plant growth hormones are being tested. A better growth of calluses seems to be favored by the contribution of cytokinins.

Germination tests are also underway on Abies nebrodensis pollen samples stored at low temperatures (Fig. 7).

Remote sensing via drone and monitoring activities of the LIFE4FIR project

The remote sensing via drone of the LIFE4FIR project

At the beginning of October 2020 the survey of the Abies nebrodensis natural are was carried out using a drone equipped with multispectral cameras. Remote sensing allows the monitoring of the health of trees and habitat through the measure of the radiation reflected by the vegetation.

During the drone flight, panoramic shots of the habitat and of the individual trees of the Abies nebrodensis population were acquired.

Phytosanitary monitoring and laboratory activities of LIFE4FIR project

Phytosanitary surveys were carried out in November 2019 and in October 2020. Trees were subjected to a careful visual examination to evaluate their vegetative condition based on observations of the crown shape and transparency, turning foliage, presence of declining, desiccated or damaged parts, occurrence of lesions.

Laboratory analysis for LIFE4FIR monitoring activities

Laboratory analysis of collected samples were conducted through: observations under stereomicroscope, isolation and culture of fungal colonies and their genetic characterization through PCR amplification and sequencing of target loci for their identification. This allowed identification of the fungal microflora associated with the observed alterations and to detect the possible presence of harmful pathogens.

Coordination meeting for the 12 months of the LIFE4FIR project – 12-13 October 2020

The beneficiaries of the LIFE4FIR European project met in Palermo on 12 and 13 October 2020. During the meeting, progresses and results obtained in each action have been presented by each partner, and the next steps to be taken in the continuation of the project have been discussed.

Certainly one of the most relevant issues has been the impact of COVID-19 on project activities. The beneficiaries have taken all possible containment actions, but the possibility of having an impact on original scheduling remains, also in light of the uncertainty regarding the pandemic dynamics of the future months.
