Understory Regeneration

La vegetación leñosa en helechales y bosque de ribera en la reserva científica Ebano Verde, República Dominicana (Woody vegetation in fernlands and riparian forests in Ebano Verde scientific reserve, Dominican Republic)

Spanish

Antecedentes

De 1940 a 1970, áreas deforestadas en la Cordillera Central de la República Dominicana fueron sujetas a incendios rutinarios lo cual causó erosión intensa y llevo al establecimiento de Dicranopteris pectinate, una especie de helecho de sotobosque. Esta especie de helecho rápido forma comunidades estables que inhiben el crecimiento de especies maderables e impide la sucesión natural del bosque. Se ha observado un fenómeno similar dentro de la Reserva Científica Ébano Verde en la República Dominicana.

Indigenous Woody Species Diversity in Eucalyptus globulus Labill spp. globulus Plantations in the Ethiopian Highlands

background

This study evaluates the regeneration of native woody species in eucalyptus plantations in the central highlands of Ethiopia.

Research Goals & Methods

Understory trees and shrubs were identified and measured in 11 year old plantations at Chancho where no natural forests remain, and in 37 year old plantations at Menagesha where remnant natural forests exist.

Growth of dipterocarp seedlings in artificial gaps: An experiment in a logged-over rainforest in South Kalimantan, Indonesia

Background

Regeneration of dipterocarps following logging has become a crucial issue in tropical forest management. Secondary forest frequently and rapidly replaces dipterocarps in large logged-over patches. If unmanaged, these secondary forest patches are often composed of unmerchantable early-succession species. It has been hypothesized that dipterocarps grow most successfully in small gaps.

The Apparent Paradox of Reestablishing Species Richness on Degraded Lands with Tree Monocultures

background

This article discusses the use of tropical tree plantations as an approach to rehabilitation of degraded landscapes. For extremely degraded sites, the use of plantations may provide the proper shade, microclimate and protection for other species to colonize the understory. Research on the use of plantations in restoration is discussed, with examples primarily from Puerto Rico.

Forest Regeneration in a Chronosequence of Tropical Abandoned Pastures: Implications for Restoration Ecology

Background

During the mid‐1900s, most of the island of Puerto Rico was deforested, but a shift in the economy from agriculture to small industry beginning in the 1950s resulted in the abandonment of agricultural lands and recovery of secondary forest. This research examines the natural regeneration patterns on these abandoned agricultural lands in four different regions of Puerto Rico.

Environmental Services of Native Tree Plantations and Agroforestry Systems in Central America

Background

Plantations and agroforestry systems supply wood and environmental services such as carbon sequestration and recovery of biodiversity. At the time of writing (2004), Central American countries were developing systems of payments for environmental services to encourage the development of these systems.

The Effect of a Teak (Tectona grandis) Plantation on the Establishment of Native Species in an Abandoned Pasture in Costa Rica

background

This study compares native tree species recruitment in the understory of a 10-year-old teak plantation in premontane wet forest in Costa Rica to the native tree species recruitment on nearby abandoned agricultural land.

Release from Root Competition Promotes Tree Seedling Survival and Growth Following Transplantation into Human-Induced Grasslands in Sri Lanka

background

This study evaluates the growth and survival of four native tree species planted as seedlings in grasslands situated in previously abandoned tea plantations.

Research Goals & Methods

Each seedling underwent one of eight different treatments based the various combinations of: with or without root competition, shoot competition, and vertebrate herbivory. Seedlings that died within the first month were replaced. Growth and survival was evaluated at 18 and 28 months.
