Seed germination and seedling establishment of Neotropical dry forest species in response to temperature and light conditions

Background

Site conditions in restoration projects vary widely, with proper conditions for germination not always available for a given species. This study examines the germination requirements of Cedrela odorata, Guaiacum sanctum and Calycophyllum candidissimum seeds under varying light conditions beneath the canopy of a dry forest in Nicaragua.

Reforestation with Native Species in the Dry Lands of Panama

BACKGROUND

Natural populations of precious timber species in Panama are being overexploited, and some have been registered in the IUCN Red List in recent years. Within the overall framework of natural resource scarcity and mounting effects of climate change, the need for sustainable production of native trees that offer added values of water cycle regulation, soil improvement, and biodiversity conservation is stressed.

Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year results

Background

Commercial forestry plantations have consistently relied on a limitd number of species, often favoring exotic species over native ones. This is mainly due to a lack of information or understanding related to the silviculture of native species plantations. This article uses a long-term experiement site in Costa Rica's La Selva Biological Station to work towards filling this knowledge gap.

Growth of native forest species planted on abandoned pasture land in Costa Rica

Background

Reforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species.

Growth characteristics of some native tree species used in silvopastoral systems in the humid lowlands of Costa Rica

Background

Degraded pastures established throughout Central America in the latter 20th C are gradually transitioning to silvopasture or secondary forest. Understanding growth characteristics of trees on these lands is important for proper management.
