Fires in exotic forest plantations of Zimbabwe: Causes and management strategies

BACKGROUND

Of the 201,704-ha allocated to plantation forestry in Zimbabwe, 95,754-ha is usable. Forest plantations are mainly composed of Eucalyptus, Wattle and Pine. The dominant species grown are Pinus patula, P. taeda, E. grandis and Acacia mearnsii. Revenue is generated from timber exports. Forest fires are the major contributors of significant financial losses in these commercial plantations. Hence this article examines the causes of these fires and possible strategies for mitigating these anthropogenic fires.

A Comparative Assessment on Regeneration Status of Indigenous Woody Plants in Eucalyptus grandis Plantation and Adjacent Natural Forest

background

This study investigates and compares diversity, density and species composition of naturally regenerated woody plants under Eucalyptus grandis plantations and the adjacent natural forest in southwestern Ethiopia.

research goals & methods

Vegetation data was collected from 40 sample plots, 20 in natural forest and 20 in plantations. Within the plots plant species were identified, DBH of all trees measured using a caliper; total heights of larger trees were measured using hypsometer.

Does Weeding Promote Regeneration of an Indigenous Tree Community in Felled Pine Plantations in Uganda

background

This study evaluates a management scheme to cut vines, grasses, and shrubs to promote regeneration of indigenous trees subsequent to removal of plantation softwoods over a period of 3 years in Kibale National Park, Uganda.

Research Goals & Methods

Sampling of tree species from seedlings to adults were identified to species. The diameter of all stems more than 1.2m tall were measured at that height (DBH). The plots were subjected to subsequent cutting of weeds on average once every 7 months.

Manual of Reforestation and Erosion Control for the Philippines

background

This manual provides a detailed guide to reforestation, including information about species selection, nursery techniques, site preparation and plantation design, weed and fire control, stand improvement and other practical aspects of establishing and managing tree plantations. Additionally, there is a large portion devoted to erosion control, using trees and engineered structures to stabilize slopes and decrease the velocity of water runoff.

Evaluation of Reforestation Potential of 83 Tree Species Planted on Imperata cylindrica Dominated Grassland – A case Study from South Kalimantan, Indonesia

background

In this study, 83 tree species (native and exotic) were tested for their growth and survival in species selection trials in South Kalimantan, Indonesia.

Research Goals & Methods

The trees were planted between January 1987 and December 1988 in areas dominated by the exotic grass Imperata cylindrica and weeding was conducted twice a year.

Forestry Project for the Basin of the Chinchiná River, an Environmental and Productive Alternative for the City and the Region

Background

Over the last century, Andean watershed within Colombia has faced threats of uncontrolled deforestation, which have been driven by a rapid expansion of agriculture and cattle grazing. It is imperative that these trends be halted and reversed, thus the FAO proposes the reforestation of watersheds, which will improve the regulation of hydaulic flows to populations living in and downstream from river basins. This project planning document describes one of these programs, PROCUENCA-FAO, which began in 2001 and focuses on the Chinchiná River watershed.
