18 Secondary Forests in West Africa: A Challenge and Opportunity for Management

background

This chapter discusses the importance and threats to secondary forests in West Africa, and the description of the floristic diversity and forest succession in secondary forest ecosystems. In addition, silvicultural and complementary management systems and the opportunities and challenges related are also discussed.

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.

The Restoration of Degraded Forests in Ghana: A Case Study in the Offinso Forest District

background

This study investigates how density and diversity of key native tree saplings differ in different plantation stand types in plantations adjacent to a degraded forest reserve in the Ashanti Region of Ghana. The influence of overstory species composition on natural regeneration of single exotic (Cedrella odorata and Tectona grandis) and mixed stands (Khaya grandifoliola, Antiaris toxicaria, Ceiba pentandra, Triplochiton scleroxylon, Terminalia superb, Terminalia ivorensis and Anopyxis klaineana) of native species was assessed.

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).

Expediting Reforestation in Tropical Forests Grasslands: Distance and Isolation from Seed Sources in Plantations

background

This study investigates the potential use of tree plantations to facilitate regeneration of indigenous trees in successionally arrested grassland. It focuses on how characteristics of the plantations and native species can determine the type of regeneration occurring in Kibale National Park, Uganda.

Restoration of Dry Afromontane forest using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidata

Background

Shrubs are often considered competitive barriers for seedlings planted in reforestation programs, although they can facilitate tree recruitment, especially in ecosystems under high abiotic stress. An alternative reforestation technique using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidata was tested in exclosures in northern Ethiopia.

The Savanna Tree Acacia polyacantha Facilitates the Establishment of Riparian Forests in Serengeti National Park, Tanzania

background

This study tests if stands of Acacia polyacantha facilitate the establishment of forest trees by examining the distribution, growth, and survival of juvenile forest trees. The influence of stand size, locations within the stand, presence of canopy trees, competition from grasses, effects of fires and effects of thorny shrubs on herbivore exclusion and conditions for establishment of A. polyacantha in grasslands were examined in Serengeti National Park of Tanzania.

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.

Manejo del fuego y restauración de bosques en la reserva de la biosfera sierra de Manantlán, México (Fire management and and forest restoration)

Los autores analizan la incidencia de incendios forestales y los efectos de los regímenes de fuego sobre los bosques de la Reserva de la Biosfera Sierra de Manantlán en el occidente de México, y se presentan las líneas de acción estratégicas del Programa de Manejo del Fuego y Restauración de Bosques de esta área protegida.

A pesar de los esfuerzos de supresión de los incendios forestales en México, se observan tendencias de aumento en la superficie quemada y en la severidad de los efectos del fuego.
