Promoting Biodiversity: Advances in Evaluating Native Species for Reforestation

background

This article describes the design of a long-term species screening trial conducted at La Selva Biological Station in Costa Rica.

Research Goals & Methods

Growth and survivability data is presented for 84 species (17 popular exotics used for timber and 67 little-known local species with timber potential) at 3 years of age.

Reforestation of Abandoned Pastures: Silvicultural Means to Accelerate Forest Recovery and Biodiversity

Background

Despite the 2736 native tree species in Ecuador, the majority of forestation activities in the country are based on exotic pines and eucalypts. In this book chapter, the authors describe the reason for this neglect being the lack of knowledge on the ecology and silvicultural treatment and the lack of nurseries growing these species.

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.

Exotic Trees as Nurse-Trees for the Regeneration of Natural Tropical Forests

Background

This article challenges widely-held views that the presence of exotic tree plantations in the tropics harm the environment. Through collecting evidence from experiences in tropical countries, the authors argue that exotic tree canopies exert protective functions - a nurse effect - for the regeneration of natural forest.

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.

Selecting framework tree species for restoring seasonally dry tropical forests in northern Thailand based on field performance

Background

Framework tree species are indigenous forest tree species, planted to complement and accelerate natural regeneration of forest ecosystems and encourage biodiversity recovery, on degraded sites. This study tests the extent to which 37 native forest tree species might act as framework tree species to accelerate recovery of evergreen, seasonal forest in a degraded upper watershed in Doi Suthep-Pui National Park in northern Thailand.

Poverty reduction in the Doi Mae Salong Landscape

Background

The Doi Mae Salong Landscape has experienced deragadation in ecosystem services due to a variety of reasons along with the significant poverty and high risk to climatic variations. The IUCN partnered with the Supreme Commander’s Office of the Royal Thai Armed Forces to pursue forest restoration and support local livelihoods. The program ran from 2010 to 2013 in the Chiang Rai Province of Thailand.
