IUFRO Spotlight #85 - Variety: the spice of life, also for future forests
*IUFRO Spotlight is an initiative of the International Union of Forest
Research Organizations. Its aim is to introduce, in a timely fashion,
significant findings in forest research from IUFRO officeholders and member
organizations to a worldwide network of decision makers, policy makers and
researchers. IUFRO will encapsulate, and distribute in plain language,
brief, topical and policy-relevant highlights of those findings, along with
information on where/how to access the full documents.*
*Occasionally, IUFRO Spotlight also presents special activities such as
sessions at major IUFRO congresses or the work of the IUFRO Task Forces.
These focus on emerging key issues that contribute to international
processes and activities and are of great interest to policy makers and to
groups inside and outside the forest sector. With those criteria in mind,
the Spotlights for the next several months will highlight the undertakings
and goals of the IUFRO Task Forces. The IUFRO Spotlights will be
distributed in a periodic series of emails as well as blog postings.*

Forests in the Mediterranean and similar biodiversity hotspot regions are
degrading rapidly due to the interaction of multiple stressors – both
natural and anthropogenic.
The accelerated degradation poses a serious threat to the diversity of
forest genetic resources (FGR).
To that end, a IUFRO Task Force (TF): *Strengthening Mediterranean Nursery
Systems for Forest Reproductive Material Procurement to Adapt to the
Effects of Climate Change*, has been organized to investigate the issue.
While the TF title may be somewhat unwieldy, the TF's role is clear: to
provide the basic scientific information needed to maintain diversity in
the forest nursery production chain; to apply serious and scrupulous
certification criteria; and to support the adaptation of future forests to
environmental changes.
At this time, "there is an increasing risk of irreversible losses of many
endemic forest tree species/populations or of unique marginal/peripheral
ecotypes harbored in biodiversity hotspot regions due to climate change
effects," said Dr. Giovanbattista de Dato, of Italy's Council for
Agricultural Research and Economics (CREA) and Coordinator of the TF.
The TF is focusing on how to improve the quality and suitability of the
forest reproductive material (FRM) used in forest plantings, how to
preserve high levels of genetic diversity in the produced FRM and how to
avoid extensive losses in forests caused by using FRM that is maladapted or
has low genetic variation; parameters that are especially important for the
resilience and sustainability of forests in the face of climate change.
This requires the collected FRM to be as diverse as possible. The above
goal can be achieved by securing the selection of different (non-related)
mother trees within and among populations.
A high degree of diversity is needed in the case of FRM transfer to distant
areas or to different climates, to ensure the local adaptation of the
transferred planting material.
"Diversity is the fundamental element of ecosystems, species and
populations that safeguards their survival, growth, long-term adaptation
and evolution.
"There is a need to initiate a process to collect, catalogue and combine
the existing knowledge on the availability and use of forest basic
reproductive material in the Mediterranean basin in order to achieve the
harmonization of all required steps," Dr. de Dato said.
"Economic and societal aspects have to be overcome," said Dr. Fulvio Ducci,
a colleague of Dr. de Dato at CREA. "Especially in the Mediterranean basin
it's not rare that the forest economy is a subsistence economy, the forest
nurseries are not well equipped, and their personnel often may not be
well-trained. And, frankly, there is often little attention paid to the FRM
certification and identification systems."
One of the major challenges, according to Dr. Paraskevi Alizoti, of the
Aristotle University in Thessaloniki, Greece, and Deputy Coordinator of the
TF, is that nurseries often gravitate toward fast-growing seedlings. While
this may facilitate a quick turnover, it results in culling seedlings that,
due to their genetic makeup, may be slow growth starters but tend to grow
faster later in the course of their development, or bear other traits of
adaptive significance that would assist in adaptation and survival in an
environment that, due to climate change, is continuously changing.

To meet those challenges, the TF's goal is to raise awareness among nursery
managers, forest managers and owners on the importance of preserving the
genetic variability of FRM throughout the nursery system as it represents
an active form of adaptation.
"Disseminating a flowchart of the correct steps and actions that need to be
taken to maintain and use the forest genetic resources (FGR) to the nursery
managers, forest managers and nursery owners can be a major step forward,"
Dr. Alizoti said.
At the end of the TF's five-year lifespan a shared information base on the
seed forests of the Mediterranean regions will be one of the expected
results. Then, as Dr. Ducci noted, convincing the various countries to
adopt effective identification and certification systems could be a great
result.
And, Dr. de Dato added, another positive outcome would be the development
of guidelines for nursery managers, forest managers and owners, that
explain, clarify and stress the importance of conserving genetic
variability along the nursery chain, due to its key role in the adaptation
of species and populations to climate change.
"With more existing variation among the individuals within a population, it
is more likely that some of them will be better suited to the environmental
challenges to be faced.
"In other words, genetic diversity guarantees the greater ability of a
species or a population to adapt and survive in a continuously changing
environment due to climate change and this can be secured by the high level
of genetic variation harbored in the FRM produced by forest nurseries that
will then be used for forest plantings," he concluded.

*The IUFRO Task Forces are established on a temporary basis during each
5-year IUFRO Board term and focus on emerging key forest-related issues.
The nine current TFs will run till 2024 at which time their relevance will
be assessed in relation to the forest issues of the day.*
