A review of the floral composition and distribution of mangroves in Sri Lanka

Background

The article reviews literature on the numbers and distributions of Sri Lankan mangrove species and highlights the causes of overestimation. It also attempts to provide an accurate count based on standardized fieldwork over a 4-year period along the coast between Palatupana and Puttalam, Sri Lanka. The authors name some examples of mischaracterized or misidentified species from previous studies and address the importance of clearly defining the terms for mangroves.

Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa Rica

Español

Antecedentes

El entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas.

Can tropical farmers reconcile subsistence needs with forest conservation?

background

Despite efforts to protect tropical rainforests through various policy initiatives, forests continue to face pressure from smallholders' subsistence needs, especially in montane regions. This paper proposes a means to turn abandoned montane pastoral land into productive agroforestry land as a viable alternative to further encroachment on existing forests.

Differences in Seedling Survival and Growth among Tropical Rain Forest Pioneers in Relation to Canopy Openness and Herbivory.

Background

The study monitored the effect of canopy openness and herbivore damage on seedling survival and growth of 960 individuals of six pioneer tree species: Dillenia triquetra, Macaranga indica, Macaranga peltata, Schumacheria castaneifolia, Trema orientalis, and Wendlandia bicuspidata.

Assessing and Monitoring Forest Biodiversity: A Suggested Framework and Indicators

background

This study looks at afforestation and reforestation (A/R) projects that are part of the Kyoto Protocol's Clean Development Mechanism. The study seeks to determine whether large-scale A/R projects meet the twin goals of carbon sequestration and sustainable development, using projects in India's Karnataka State as case studies.

Gmelina Boom, Farmers Doom: Tree growers risks, coping strategies and options

Background

The widespread smallholder tree plantations of Gmelina arborea established in the South Philippines in the 1980s led to price boom and bust cycles rather than the expected economic returns for growers. This study evaluates grower responses to the timber price bubbles of the 1990s and recommends policy responses.

Rehabilitation of Nickel Mining Sites in New Caledonia

background

New Caledonia has the fourth largest Nickle deposits in the world, and major mining companies have frequently used open-pit nickle extraction. New Caledonia boasts around 1,137 endemic species, and distrubance from mining threatened many of them. The government came under pressure to regulate the mining sector and rehabilitate mined areas damaged from mining pollution. Both the waterways and New Caledonia's tourism sector suffered from the pollution.
