Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

Understory Development in Young Cordia alliodora Plantations

background

This article presents the findings of a study evaluating the biomass and composition of understory plants in 1- and 5- year old plantations at the La Selva Biological Station in Costa Rica.

Reserach Goals & Methods

This study sampled plantations of Cordia alliodora in monoculture plots and in polyculture plots with trees interplanted with monocots (Euterpe macrospadix, Euterpe oleracea, and Heliconia imbricata).

Effects of Artificial Roosts for Frugivorous Bats on Seed Dispersal in a Neotropical Forest Pasture Mosaic

background

This article evaluates whether the installation of bat roosts into abandoned pasture sites can attract frigivorous bats into pasture areas and encourage seed rain of early-successional plant species.

Farmer Participation in Reforestation Incentive Programs in Costa Rica

background

This article evaluates the participation of farm households in reforestation incentive programs in Costa Rica from 1988 to 1995. The Forestry Bond Certificate in Advance (CAFa) was started in 1988 as a grant of 100,000 colones per hectare (it increased to 120,000 colones per hectare) for reforestation to be disbursed over 5 years of plantation establishment. The Forestry Development Fund (FDF) was initiated in 1989 and offers 58,000 colones per hectare over 3 years for reforestation.

Tropical Montane Forest Restoration in Costa Rica: Overcoming Barriers to Dispersal and Establishment

background

Due to the rapid pace of tropical deforestation, it is essential to design restoration experiments that both further basic knowledge of tropical ecology and inform management strategies to facilitate recovery of these ecosystems. This study synthesizes the results of recent research on tropical montane forest recovery in abandoned pasture in Costa Rica to address limitations on tropical forest recovery in abandoned pasture and designing strategies to facilitate ecosystem recovery.

Factors Limiting Tropical Rain Forest Regeneration in Abandoned Pasture: Seed Rain, Seed Germination, Microclimate, and Soil

background

This research evaluates the ability of seeds to be dispersed into and germinate in areas of abandoned pasture.

Research Goals & Methods

Seed rain, germination of tree seedlings, percent herbaceous and woody cover, soil moisture, phosphorous, air temperature, and other microclimate conditions were tested in plots located 250m and 25m from the forest edge as well as within the primary forest.

Canopy development in tropical tree plantations: a comparison of species mixtures and monocultures

Background

The establishment of plantation monocultures has dominated much of the intensive forest management practiced in the humid tropics of the Americas, with most forestry research and practice concentrating on a small number of non-indigenous species. Growing interest exists in modifying these practices both by creating mixed-species plantations and by making greater use of native tree species.
