Plantation forests and biodiversity: Oxymoron1 or
opportunity?
Forests form the natural vegetation over much of the Earth’s land, and they are
critical for the survival of innumerable organisms. The ongoing loss of natural
forests,whichinsomeregionsmayhavetakenmanymillenniatodevelop,isone
of the main reasons for the decline of biodiversity. Preventing the further
destruction of forests and protecting species and ecosystems within forests have
become central issues for environmental agencies, forest managers, and govern-
ments.Inthisdifficulttasksciencehasanimportantroleininformingpolicyand
management as to how to go about this. So how do industrial and other plan-
tation forests fit into this?

With plantation forests expanding at a rate of approximately three million

land uses often benefit conservation by providing new or expanded habitat for
forest species of all kinds, from microorganisms, fungi, and insects to birds and
mammals.Thisisparticularlysowhentheuseofnativetreesleadstoaforestthat

management to improve their value for biodiversity. This applies to both the

within the plantation forest landscape.
This book is the result of ongoing collaboration among forest scientists from
numerous countries who have joined efforts under the umbrella of the Interna-
tional Union of Forest Research Organisations (IUFRO), with contributions
from the World Conservation Union (IUCN), the WWF-World Wide Fund For
Nature, and many others. The contents of this volume are derived from papers
presented at three conferences that took place in Europe and Australia between
2005 and 2006, with the aim of increasing our understanding of conservation
issues and opportunities around plantation forestry. The research presented here
covers a wide range of taxa living in forests, from lichens to primates, from
varioustemperateandtropicalregionsaroundtheworld.Thefindingsareequally
of interest to the scientific community, policy makers and forest managers. This
work can assist with the improvement of best-practice guidelines for the estab-
lishment and management of plantation forests. The topical examples of applied
conservation issues will make the volume also highly valuable for use in
conservation biology courses.
The 14 contributions presented here were first published in Biodiversity and
Conservation 17(5):925–1211 (2008). They are being released again now in book
form in view of the great interest shown by the scientific community in the
compilation. Since the conception of this project there has been an increasing
momentum towards planting more forests as carbon sinks to combat climate
change. Much of the contents of this volume are relevant to such ‘‘carbon
forests’’, and its appearance is timely. As with all types of planted forests, there
are significant win-win opportunities for multiple benefits, including biodiversity
conservation.

Abstract Losses of natural and semi-natural forests, mostly to agriculture, are a signiW-
cant concern for biodiversity. Against this trend, the area of intensively managed plantation
forests increases, and there is much debate about the implications for biodiversity. We pro-
vide a comprehensive review of the function of plantation forests as habitat compared with
other land cover, examine the eVects on biodiversity at the landscape scale, and synthesise
context-speciWc eVects of plantation forestry on biodiversity. Natural forests are usually
more suitable as habitat for a wider range of native forest species than plantation forests but
there is abundant evidence that plantation forests can provide valuable habitat, even for
some threatened and endangered species, and may contribute to the conservation of biodi-
versity by various mechanisms. In landscapes where forest is the natural land cover, planta-
tion forests may represent a low-contrast matrix, and aVorestation of agricultural land can
assist conservation by providing complementary forest habitat, buVering edge eVects, and
An ‘oxymoron’ is a Wgure of speech using an intended combination of two apparently contradictory
terms.

increasing connectivity. In contrast, conversion of natural forests and aVorestation of
natural non-forest land is detrimental. However, regional deforestation pressure for agricul-
tural development may render plantation forestry a ‘lesser evil’ if forest managers protect
indigenous vegetation remnants. We provide numerous context-speciWc examples and case
studies to assist impact assessments of plantation forestry, and we oVer a range of manage-
ment recommendations. This paper also serves as an introduction and background paper to
this special issue on the eVects of plantation forests on biodiversity.

Introduction
Deforestation is a major cause of the loss of biological diversity and a signiWcant global
concern (e.g., Wilson 1988; Brook etal. 2003; Laurance 2007) as it is estimated that more
than half of the known terrestrial plant and animal species live in forests (Millenium
Ecosystem Assessment 2005). Globally, the area of natural and semi-natural forests
decreases by some 13millionha annually (ca. 0.3%), mostly due to conversion to
agriculture (FAO 2006a, 2007). Plantation forests constitute only about 3.5% of the total
forest area (ca. 140millionha) but the area of plantation forests is increasing by about
2–3millionha (ca. 2%) annually, against the trend of a globally falling forest cover (FAO
2006a, Table1). According to the current Food and Agriculture Organization (FAO) and
International Union of Forest Research Organisations (IUFRO) deWnitions (e.g., FAO
2006a), plantation forests are established through planting or seeding of one or more indig-
enous or introduced tree species in the process of aVorestation or reforestation. Particularly
in the Wrst rotation after establishment, stands are typically of an even-aged structure with
an even spacing of trees. Their main objective is often the production of timber or fuel
wood (plantations provided about 35% of the global wood supply in 2000) but some are
established to reduce erosion, Wx carbon, or provide other environmental, economic, or
social beneWts. Many plantations are intensively managed including the use of improved
tree varieties and silvicultural operations that may involve site preparation (e.g., ploughing,
harrowing, use of fertilizers, and herbicides), thinning, and clear-cut harvesting, often with
short rotations (e.g., <30years between planting and harvesting, or as little as 5–10years
for poplars and some tropical species). Apart from such plantations, the FAO deWnition for
“planted forests” (FAO 2006b) also includes some types of semi-natural forests that were
established through planting or seeding by human intervention. In reality, it is often diY-
cult to categorise planted forests such as those that have been established as pure stands by
planting or sowing centuries ago, and have since become more diverse by natural
processes, which is common in much of Europe.
The implications for the conservation of forest biodiversity of plantation forests and their
continuing expansion are being debated vigorously. Although plantation forest managers
increasingly recognise the need to conserve biodiversity, and many adhere to sustainable
management guidelines such as those of the Forest Stewardship Council (FSC Forest
Stewardship Council 2007a) or the Programme for the Endorsement of Forest CertiWcation
schemes (PEFC 2007), certiWcation does not always beneWt biodiversity conservation
(Gullison 2003), and criticism of plantation forestry from some stakeholders remains strong
(e.g., Cossalter and Pye-Smith 2003, and see below). Plantation forests are the focus of
