Flexible Mating System in a Logged Population of Swietenia Macrophylla King (Meliaceae): Implications for the Management of a Threatened Neotropical Tree Species

Scarce information on canopy dimensions re¯ects the dif®- culties associated with measuring crown height, width, depth, and area in tall, humid tropical forests. New ®eld and spaceborne observations provide an opportunity to acquire these measurements, but the accuracy and reliability of the methods are unknown. We used a handheld laser range ®nder to estimate tree crown height, diameter, and depth in a lowland tropical forest in the eastern Amazon, Brazil, for a sampling of 300 trees strati®ed by diameter at breast height (DBH). -

E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al. -

Ecology and Distribution of the Malesian Podocarps Neal J
4 Ecology and Distribution of the Malesian Podocarps Neal J. Enright and Tanguy Jaffré ABSTRACT. Podocarp species and genus richness is higher in the Malesian region than anywhere else on earth, with maximum genus richness in New Guinea and New Caledo- nia and maximum species richness in New Guinea and Borneo. Members of the Podo- carpaceae occur across the whole geographic and altitudinal range occupied by forests and shrublands in the region. There is a strong tendency for podocarp dominance of vegetation to be restricted either to high- altitude sites close to the limit of tree growth or to other sites that might restrict plant growth in terms of water relations and nutri- ent supply (e.g., skeletal soils on steep slopes and ridges, heath forests, ultramafic parent material). Although some species are widespread in lowland forests, they are generally present at very low density, raising questions concerning their regeneration ecology and competitive ability relative to co- occurring angiosperm tree species. A number of species in the region are narrowly distributed, being restricted to single islands or mountain tops, and are of conservation concern. Our current understanding of the distribution and ecology of Malesian podocarps is reviewed in this chapter, and areas for further research are identified. INTRODUCTION The Malesian region has the highest diversity of southern conifers (i.e., Podocarpaceae and Araucariaceae) in the world (Enright and Hill, 1995). It is a large and heterogeneous area, circumscribing tropical and subtropical lowland to montane forest (and some shrubland) assemblages, extending from Tonga in Neal J. Enright, School of Environmental Science, the east to India in the west and from the subtropical forests of eastern Australia Murdoch University, Murdoch, Western Austra- in the south to Taiwan and Nepal in the north (Figure 4.1). -
26 Extreme Trees Pub 2020
Publication WSFNR-20-22C April 2020 Extreme Trees: Tallest, Biggest, Oldest Dr. Kim D. Coder, Professor of Tree Biology & Health Care / University Hill Fellow University of Georgia Warnell School of Forestry & Natural Resources Trees have a long relationship with people. They are both utility and amenity. Trees can evoke awe, mysticism, and reverence. Trees represent great public and private values. Trees most noticed and celebrated by people and communities are the one-tenth of one-percent of trees which approach the limits of their maximum size, reach, extent, and age. These singular, historic, culturally significant, and massive extreme trees become symbols and icons of life on Earth, and our role model in environmental stewardship and sustainability. What Is A Tree? Figure 1 is a conglomeration of definitions and concepts about trees from legal and word definitions in North America. For example, 20 percent of all definitions specifically state a tree is a plant. Concentrated in 63% of all descriptors for trees are four terms: plant, woody, single stem, and tall. If broad stem diameter, branching, and perennial growth habit concepts are added, 87% of all the descriptors are represented. At its most basic level, defining a tree is not species based, but is a structural definition. A tree is represented by a type of plant architecture recognizable by non-technical people. The most basic concepts for defining a tree are — a large, tall, woody, perennial plant with a single, unbranched, erect, self-supporting stem holding an elevated and distinct crown of branches, and which is greater than 10 feet in height and greater than 3 inches in diameter. -
