Understory Regeneration
Regeneration of Indigenous Trees in Mgahinga Gorilla National Park, UgandabackgroundThis study examines the dominant exotic species, their distribution and effect on the regeneration of indigenous tree species in the formerly encroached area of Mgahinga Gorilla National Park, southwestern Uganda. The 4 habitat types examined were exotic woodlots, old croplands and natural forest habitat. Research Goals & MethodsIndigenous species diversity was assessed by systematic sampling of the vegetation and soils in transect plots. Available with subscription or purchase |
Impact of Exotic Plantations and Harvesting Methods on the Regeneration of Indigenous Tree Species in Kibale Forest, UgandabackgroundIn the late 1960s and early 1970s, exotic tree plantations were established in hilltop grassland sites of the Kibale Forest Reserve. In the late 1990s and early 2000s, many of these sites were selected for logging to encourage growth of native trees. Research Goals & MethodsThis study assesses the impact of both pitsawing and sawmilling of exotic species plantations on the colonization and regeneration of indigenous species. Tree enumeration was conducted within plots representing the different plantation types and harvesting methods in order to determine indigenous species richness and diversity.

Caracterização do Dossel e do Estrato de Regeneração Natural no Sub-Bosque e em Clareiras de Uma Florestal Estacional Semidecidual no Município de Viçosa, MGThe authors analyzed clearings in a forest reserve belonging to the Federal University of Viçosa, MG, to compare the species and composition of clearing and forest understory vegetation. The found that the level of diversity (Shannon index) and species found (n= 69) were similar in the clearings and the understory in the surrounding forest. Coffee (Coffea arabica) and Picramnia regnellii were the most common species in both the clearings and the understory. The authors suggest that the dominance of coffee may be problematic for the regeneration of native species. Open access copy available |

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)SpanishAntecedentesDe 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. Open access copy available |
Indigenous Woody Species Diversity in Eucalyptus globulus Labill spp. globulus Plantations in the Ethiopian HighlandsbackgroundThis study evaluates the regeneration of native woody species in eucalyptus plantations in the central highlands of Ethiopia. Research Goals & MethodsUnderstory 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, IndonesiaBackgroundRegeneration 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. Available with subscription or purchase |
The Apparent Paradox of Reestablishing Species Richness on Degraded Lands with Tree MonoculturesbackgroundThis 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. Open access copy available |
Forest Regeneration in a Chronosequence of Tropical Abandoned Pastures: Implications for Restoration EcologyBackgroundDuring 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. Available with subscription or purchase |
