Managed forests are important landscape components in tropical regions. But an understanding of the response of the forests’ biodiversity to silvicultural interventions has been limited.
Finding out more about how that biodiversity responds was a fundamental question behind the research leading to the publication of Medium-term dynamics of tree species composition in response to silvicultural intervention intensities in a tropical rain forest. Read more…
American Indian forestry: blending science and tradition
For thousands of years, American Indians have been managing the forests in which they live.
Today, with trained professionals who are tribal members, their forests are managed with modern tools and methods; include manufacturing facilities and address global forest issues such as climate change, forest certification, carbon sequestration and a changing work force.

Dealing with uncertainties
REDD+ (reducing greenhouse gas emissions from deforestation and forest degradation, and enhancing forest carbon stocks in developing countries) is an evolving mechanism for climate change mitigation under continued debate within and outside of the UN Framework Convention on Climate Change (UNFCCC). While it has the potential to realize its primary climate change mitigation objective, there is considerable uncertainty regarding its actual or potential impacts on biodiversity, forests and the livelihoods of people in the tropical and sub-tropical forested landscapes where REDD+ implementation is envisaged.

The session addressed the very important issue of the trade-offs between biomass harvest, carbon storage and biodiversity. Biomass harvest is negatively correlated with biomass storage and, in most cases, with biodiversity.
A key finding of the first presentation, which dealt with a permanent plot experiment in the Amazon, is that logging intensity affects biomass recovery rate and period. The study determined that increased logging intensity is ensued by increased recovery rate, but increases the recovery period.
Another presentation highlighted the effects of logging after 30 years on tree diameter, timber species and floristic diversity. Floristic diversity had recovered to the original state. Conversely, diameter distribution was less heterogeneous and tree species composition had shifted to pioneer and other light demanding species.
The role of individual big trees was also highlighted in a presentation. The study conducted in Pará, Amazon, found that selective logging caused a net biomass storage decrease. Moreover, selective logging creates instability in stands, which results in elevated natural mortality of individual big trees, even 8 years subsequent to logging.
Another presentation emphasised the role of disturbance regimes, showing data that El Nino decreased standing biomass more than logging; where mature stands suffered more damage than newly logged stands. Emphasis was placed on the importance of rotation cycles, as the risk of devastating disturbance regimes increased with increasing rotation periods.

The session offered insight into functional ecology, with emphasis on climatic conditions along elevation gradients showing that biodiversity decreases with increasing altitude. It also dealt with the provision of ecosystem services in relation with biodiversity. Biodiversity is essential for pest damage resistance, for example. Source dilution, chemical signals and activity of natural enemies are identified as being essential for ensuring low pest damage. With increased source dilution, pests are less likely to establish themselves in a diverse setting. With increased chemical signals associated with diverse flora, pests are less likely to find their favourite source. And with a high number of natural enemies, whose presence is correlated with high biodiversity, pests are less likely to cause damage. Hence, diversification on a stand/landscape level is needed to ensure the provision of forest ecosystem services.
Plant conservation in Southeast Asia was another topic. In Malaysia, for example, efforts to preserve plants have become a prevalent goal for scientists. Diversity is vast, and since 40 – 50 % of the preserved species are endemic, 24% of which are either endangered (EN) or critically endangered (CR), conservation is a central goal. While the pleas of scientists are being heard in some cases, legal frameworks are needed to protect these species.
A presentation on the carbon sequestration potential for complex mosaic forest landscapes in western Mexico aimed at addressing shifting cultivation, framed in the carbon emission discourse. With shifting cultivation, carbon is released to the atmosphere, adding to GHG concentrations. However, the study showed that on a landscape level, there are no net carbon dioxide emissions, as the carbon sequestration rate of forest re-growth compensates for the carbon emission from shifting cultivation.
The presentation entitled “Native forest cover increase: drivers and implications on ecosystem services”, focused on why some areas in the Piracicaba river basin were allowed to reforest. Satellite imagery helped determine deforestation and reforestation from 1990 – 2010. Having preselected variables, the results demonstrate that natural reforestation occurs when slopes exceed 30%, when water proximity is less than 100 m, when annual rainfall exceeds 1400 mm, when elevation is lower than 400 m below sea level or more than 800 m above sea level, and when vicinity to towns is more than 7 km.
The final paper focused on Chakras, forestry systems that are employed by indigenous peoples in the Amazon. Plant composition in Chakras is heterogeneous; they provide multiple sources of food, are biodiverse and function as stores of carbon. The presented study demonstrated that in Chakras, fauna is more diverse, carbon storage is higher in both biomass and necromass than in comparable Cocoa plantations.

What REDD+ looks like on the ground: evidence from the Amazon and beyond
Moderator: Niels Elers Koch, IUFRO President
Thursday, 13 June 2013, 08:00 – 10:00 (Santa Rosa 2)
Agricultural expansion has been identified as a key driver of deforestation in developing countries. The IPCC estimated that carbon dioxide emissions, as a consequence of deforestation, amounted to 20% of all anthropogenically induced carbon dioxide emissions in the 1990s. Reducing Emissions from Deforestation and Forest Degradation in developing countries (REDD+), has been proclaimed an environmental policy instrument that could potentially provide mitigative benefits for net carbon emissions and biodiversity degradation.
In the session entitled “What REDD+ looks like on the ground: evidence from the Amazon and beyond”, leading scientists addressed the relationship between biodiversity, carbon, forests and people, as well as experiences with the operationalization of REDD+ in Latin America.
The Global Forest Expert Panel (GFEP), which is coordinated by IUFRO, presented a global assessment report on REDD+, which consolidates the research of more than 50 leading scientists. The report constitutes a comprehensive analysis of the synergies and trade-offs between biodiversity, forest management and REDD+.
The assessment report proposes that biodiversity is paramount, as a prerequisite for providing ecosystem services. In the face of disturbance regimes such as climate change, ecosystem resilience, a product of biodiversity, ensures ecosystem service provision.
Moreover, a successful REDD+ implementation, that achieves mitigative net carbon emissions and ensures biodiversity provision, requires, in conjuncture with the implementation, the pursuit of social objectives by securing tenure rights and local engagement. Only when tenure and property rights are clearly defined can a REDD+ implementation be effective.
The session also included presentations on a global comparative study entitled “What REDD+ looks like on the ground: Carried out by CIFOR”. The study, which is t largest project ever undertaken by CIFOR, aims to provide scientific insights on how to ensure that REDD+ measures meet the three “E’s”; Effectiveness, Efficiency, Equity. As the first phase of the study has been completed, the findings of four cases were presented during the session. For more detailed information please visit the CIFOR webpage.

Understanding Relationships between Biodiversity, Carbon, Forests and People: The Key to Achieving REDD+ Objectives
Forests harbour a major proportion of the world’s terrestrial biodiversity and provide a wide range of vitally important ecosystem services – including carbon sequestration and storage. Deforestation and forest degradation continue to erode biodiversity and the capacity of forest ecosystems to help mitigate climate change and provide the goods and services that sustain livelihoods and human well-being locally, and globally. Reducing greenhouse gas emissions from deforestation and forest degradation, and enhancing forest carbon stocks in developing countries (REDD+) is a proposed mechanism which has the potential to realise its primary objective – climate change mitigation – with variable impacts, positive and negative, on biodiversity, forests and people. REDD+ is complex, its proposed activities and implementation mechanisms not yet clearly defined, and therefore surrounded by uncertainty. Because of its high relevance to climate change mitigation, the conservation and sustainable use of forests and their biological diversity, the Expert Panel on Biodiversity, Forest Management and REDD+ was established by the Collaborative Partnership on Forests in December 2011 to carry out this assessment.
The Expert Panel included 24 scientists and other experts from a variety of biophysical and social science disciplines relevant to the topics covered in this assessment report. An additional 18 contributing authors added their expertise to the assessment. Each chapter was prepared by a team of Lead Authors and Contributing Authors led by one or more Coordinating Lead Authors. A full draft of the report and its individual chapters was peer-reviewed prior to its completion. The results of this voluntary collaboration between January and October 2012 are presented in the six inter-related chapters comprising this book.
This assessment report evaluates the implications of forest and land management interventions envisaged under REDD+ in a multidimensional and integrated fashion. It summarises the most current scientific literature that sheds light on the relationships between forest biodiversity and carbon (and other ecosystem services), how these complex relationships may be affected by management activities implemented to achieve REDD+ objectives, the potential synergies and tradeoffs between and among environmental and socio-economic objectives, and their relationship to governance issues. Based on the main findings of the assessment (summarised in Chapter 6), a policy brief entitled ‘REDD+, Biodiversity and People: Opportunities and Risks’ has been prepared especially for policy- and decision-makers.
The full report is formally presented at Forest Day 6 on 2 December during the United Nations Framework Convention on Climate Change (UNFCCC) meeting in Doha, Qatar (26 November-7 December, 2012).
The report, the policy brief and a press release – New Study Suggests Global Pacts Like REDD Ignore Primary Causes of Destruction of Forests – are available for download.

IUCN has launched a campaign, « Plant a Pledge » , and is asking readers to sign the petition at www.plantapledge.com. It takes just a minute of your time!
IUCN is hoping that you will help the campaign by reaching out as widely as possible, by helping to promote the campaign through your networks, through publicising it through the web, social media, presentations and word of mouth.
Plant a Pledge – www.plantapledge.com – is an opportunity for the global public to tell world leaders and land owners that they support the goal to restore 150 million hectares of degraded and deforested lands by the year 2020. The goal is an implementation vehicle for achieving CBD Aichi Target 15 and has become known as the “Bonn Challenge” after it was launched in Bonn, Germany, in September 2011.
The Bonn Challenge target to restore 150 million hectares by 2020 came second when over 1 million people took part in the on-line public Rio Dialogue vote for the most important global recommendation during the recent UN summit in Brazil, “Rio+20”.
Restoring 150 million hectares would inject billions of new dollars into economies every year, and would significantly help mitigate climate change, boost biodiversity and reduce poverty.
The Plant a Pledge petition will gather the signatures from people across the globe, and will be personally delivered by our Ambassador Bianca Jagger to senior delegates at an upcoming high level international meeting, urging land owners and governments to dedicate land to landscape restoration.
Help gather enough signatures to really turn the heads of those leaders and convince them to commit to the Bonn Challenge.
The website www.plantapledge.com will give you lots more information on the campaign and on forest landscape restoration.
Please go there now and sign the petition and urge all your friends, contacts and networks to do the same, by forwarding this message, and ideally also by sharing it through other means.
If you have time to explore the site, you might like to watch the videos, explore the interactive restoration globe, read the case studies and learn more about the issue and the campaign.
