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.

Kibale National Park Rehabilitation Project

Background

Kibale National Park is one of the last remaining tracks of tropical forest in Uganda. It provides great environmental benefits, specifically serving as a home to large populations of primates. The Kibale National Park Rehabilitation Project seeks to protect these benefits.

High Seedling Recruitment of indigenous Tree Species in Forest Plantations in Kakamega Forest, Western Kenya

background

The study evaluates the potential for seedling recruitment of indigenous tree species in different types of plantations and secondary forest in western Kenya. The plantations are comprised of mixtures and monocultures of single or exotic indigenous tree species.

Regeneration of Timber Species following Selective Logging in a Moist Semi-Deciduous Forest in Ghana

background

This study examines the types and frequency of natural regeneration and growth of timber tree species in 4 logging gaps: loading bays, tree-fall, primary and secondary skid trails with forest shade as control in a moist semi-deciduous forest in Ghana.

Impact of Exotic Plantations and Harvesting Methods on the Regeneration of Indigenous Tree Species in Kibale Forest, Uganda

background

In 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.

Forest Restoration in Abandoned Agricultural Land: a Case Study from East Africa

background

This study quantifies the pattern of forest recovery following clearing and 3 years of cultivation of an abandoned agricultural land adjacent to a 300ha relatively undisturbed natural forest in a moist-evergreen forest in Kibale National Park, Uganda.

Intensive Tree Planting Facilitates Tropical Forest Biodiversity and Biomass Accumulation in Kibale National Park, Uganda

background

This study investigates how intensive planting affects tropical forest regeneration and biomass accumulation in reforested sites in Kibale National Park, Uganda. The study assessed species richness of naturally regenerating (i.e. non-planted) species in the park and compared the biomass accumulation of planted versus naturally regenerating trees in sites replanted by the Uganda Wildlife Authority.

Forest Succession in Kibale National Park, Uganda: Implications for Forest Restoration and Management

background

This sudy examines forest succession in 4 plots in former grasslands adjacent to mature forests in Kibale National Park, Ngogo, Uganda. These plots were located in areas protected from fire for .58,25,9 and 30 years for plots 1,2, 3, and 4 respectively.

Enrichment Planting Does Not Improve Tree Restoration when Compared with Natural Regeneration in a Former Pine Plantation in Kibale National Park, Uganda

background

This study assesses the rate of biomass accumulation of planted seedlings relative to natural regeneration in a harvested plantation in Kibale National Park, Uganda. Enrichment planting was carried out in an area where a pine plantation had been harvested to determine the relative value of these management options.

Quarry dust emission effects on tree species diversity in Chongoni forest Reserve and vegetation characteristics in adjacent villages, Dedza, Malawi

Background

Quarry dust is widely reported to have adverse effects on both human health and plant community structure, particularly resulting in decreased diversity and ecosystem functions. Therefore, it is critical to examine and monitor the interactions between these dust particles and vegetation.

Effects of Canopy Cover and Understory Environment of Tree Plantations on Richness, Density and Size of Colonizing Woody Species in Southern Ethiopia

background

This study investigates the effects of canopy characteristics and associated understory environmental factors of tree plantations on native woody species colonization in two broadleaved and two coniferous plantations in southern Ethiopia. The plantation forests investigated are surrounded by dry Afromontane natural forest.

Recovery of Plant Species Richness and Composition in Abandoned Forest Settlement Area in Kenya

background

This paper examines natural regeneration of tree species in a former forest village settlement that had been cultivated and abandoned in Mau forest, Kenya. Following 19 years of abandonment, the site consists of 3 zones of recovery due to different degrees of degradation before abandonment, continued grazing, selective logging and firewood collection. The zones are grass zone (GZ), transition zone I (TZ I) and TZ II and secondary forests (SF).
